Gigabyte Nvidia GeForce GTX 660 Ti Opinion. Appearance and cooling system
We are rarely the opportunity to review and testing several interesting new products at once, and to make a large-scale video card test of one model of almost all manufacturers and never ever brought. Today's material is intended to correct this annoying misunderstanding, as in this article we will study and comprehensively test eight original GeForce GTX 660 Ti video cards on the GK104 graphics processor architecture "KEPLER", issued by ASUS, EVGA, Gigabyte, Inno3D, KFA2, MSI, Palit and ZOTAC. And if this method of filing information and comparison you will seem interesting to you, then in the future for serial video cards we will try our exactly similar large-scale materials. We are waiting for your feedback in the comments to the article, and immediately go to acquaintance with testing participants.
Well, now we will study in detail each of them.
They also provide basic information about the video card extended on the back of the box. Equipment, surprisingly poor - only fast installation instructions and DVI-TO-D-SUB adapter:
Probably, the cables for connecting additional power and the CD with drivers and the ASUS brand utilities are lost somewhere on the road. ASUS GeForce GTX 660 Ti Directcu II Top in China is available and costs $ 309, which is only $ 10 more expensive GeForce GTX 660 Ti reference samples. A three-year warranty period is provided on the video card.
The ASUS video card design is easily recognizable by the referring system DirectCu II closing the entire front side. The card looks stylish, but strictly:
Due to the Couple Circuit Coupling Course, the length of the video card is 269 mm, and this is the longest GeForce GTX 660 Ti of today's testing. At the same time, the thickness of the ASUS GeForce GTX 660 TI DirectCu II TOP is 38 mm, that is, no three slots it blocks, such as, for example, flagship GTX 680.
The video card is equipped with a standard set of outputs: DVI-I and DVI-D (Dual-Link), HDMI and Displayport, combined with a lattice for partial emission of a heated aircraft aircraft outside the system unit housing:
Two MIO connectors for creating 2-, 3- and 4-way SLI configurations and two six-pin connections for connecting additional power are installed in familiar to GeForce GTX 660 TI places:
Looking forward, we note that almost all other video cards of today's review have the same configuration of these connector pairs, with the exception of one product, which we will definitely say separately. Therefore, we will not stop more in this moment in the overwhelming majority of cases. We add that the recommended power of the power supply unit for a system with one such video card is 450 watts.
Asus has traditionally pleases overclocking lovers and gives its product a unique printed circuit board with a reinforced power supply system:
Six phases are allocated on the graphics processor, two, and on the power supply chain - one phase:
The proprietary digital Digi + Power supply system with the Super Alloy Power technology, which assumes the use of only high-quality and durable components, allows 30% to reduce the vendors, increase energy efficiency by 15% and extend the service life in comparison with the reference products by 2.5 times. It's great that the technologies previously used by ASUS only in HI-END products are gradually becoming accessible and transferred to the medium price segment video cards.
The graphics processor of our ASUS GeForce GTX 660 TI DirectCu II Top instance is released in Taiwan at week 18 of the current year (beginning of May), and refers to A2 revision:
Since the GK104 configuration on the GTX 660 TI has already been studied earlier, then in today's article we will emphasize your attention on changes in terms of graphics processors of video cards. And then Asus did not hit the dirt face - its graphics processor operates at 1059 MHz in conventional 3D-mode and at 1137 MHz - in forced. This, immediately say, the record frequency of the graphics processor is not only among the eight video cards of the material, but also in general all the serial-produced GeForce GTX 660 Ti.
ASUS GeForce GTX 660 TI DirectCu II Top is equipped with eight GDDR5 memory chips in FCBGA packaging with a total volume of 2 GB issued by Hynix Semiconductor Inc.:
Marking microcircuits - H5GQ2H24AFR R0c, the theoretical efficient frequency of operation is 6000 MHz, on which memory and functions. Thus, with a bus width of 192 bits, the memory bandwidth is equal to the reference for GeForce GTX 660 Ti and is 144.2 GB / s. All today's testing video cards are equipped with chips with the same labeling, but not all functioning at the same efficient frequency.
Final Specifications ASUS GeForce GTX 660 TI DirectCu II Top:
In addition to a unique printed circuit board, ASUS is ready to please and lovers of effective and, importantly, quiet cooling. Of course, the company's branded cooling system ASUS DirectCu II:
It consists of an aluminum radiator on three copper 8-mm heat pipes with direct contact and aluminum casing with two fans:
On the power elements, an additional aluminum radiator with thermal block laying, covered by an air flow of one of the fans.
Two 75 mm impeller issued by Firstd and equipped with PWM control:
The speed of their rotation is adjusted by the video card automatically in the range from 1000 to 3500 rpm. The maximum power consumption of each fan should not exceed 4.2 W.
Hereinafter, to check the temperature mode of the video card as a load, we used five test cycles. Very resource-intensive game Aliens VS. Predator (2010) with the maximum quality of graphics in the resolution of 2560x1440 pixels with anisotropic filtering level 16x, but without the use of smoothing to load the graphics processor to the maximum. Program was used to monitor temperatures and other parameters MSI Afterburner version 2.2.3 And the GPU-Z utility version 0.6.4. All tests were conducted in a closed system block case, the configuration of which you can see in the next section of the article, at room temperature 20 degrees Celsius. All video cards disassembled before testing, so after the assembly were tested on the same thermal interface on the graphics processor - the thermal pump of Arctic MX4.
We look at the temperature mode of ASUS GeForce GTX 660 TI DirectCu II TOP:
Total: 69 degrees Celsius in automatic mode of operation of fans and only 54 degrees Celsius at their maximum speed. These are excellent results, especially considering the increased frequency of the graphics processor. In addition, we advise special attention to pay for the maximum fan speed with automatic adjustment - only 1440 rpm. But, about the noise level we will talk a little later.
Overclocking potential of all video cards we studied at rated graphics processor voltage. When overclocking ASUS GeForce GTX 660 TI DirectCu II TOP did not demonstrate some outstanding results. Without loss in stability and as an image, the basic frequency of the graphics processor was possible to increase only by 50 MHz, and the video memory is 960 effective megahertz:
As a result, the frequency of the ASUS video card amounted to 1109/1187/6968 MHz:
Not the best, but not the worst overclocking result among all eight testing video cards. But the temperature mode of the video card and noise level may envy any other manufacturer:
Total 70 degrees Celsius in the peak of the load at the speed of fans 1410 rpm. Note that the peak frequency of the graphics processor according to the monitoring data was 1239 MHz.
Let's see what other manufacturers can surprise us.
From the packaging features, select a plastic window with which you can refer to the serial number on the package and directly on the video card printed circuit board:
The equipment is not as an example of the richer ASUS product and includes everything you need to connect and operate the video card, as well as bonuses in the form of stickers and a huge calendar poster:
The video card is produced in China and costs $ 309. Warranty - three years.
Even glanced at Evga GeForce GTX 660 Ti SuperClocked, you understand that this is a copy of the reference product:
Only the inscription on the plastic casing indicates that the video card is produced under the EVGA label. Outputs, of course, standard, but closed with plastic caps, and the grille is cut and is supplemented with additional slots to the maximum:
A short printed circuit board, released on reference design, well-known to our regular readers:
Under the high aluminum radiator, the batteries are hidden according to the "4 + 2 + 1" scheme (GPU + MEM + PLL) running the ON SEMICONDUCTOR NCP5392P controller:
The crystal protected by the steel frame of the graphics processor is released a week later the GPU ASUS video card - 19 week 2012:
Audit, marking and configuration do not differ. The base frequency in 3D mode is 980 MHz, in boost mode - 1059 MHz. This is the most modest acceleration among all other testing video cards. By the way, while we prepared this material, EVGA removed from the production of the EVGA GeForce GTX GTX 660 Ti SuperClocked video card, replacing it on a more high-speed FTW version with frequencies 1046/124 MHz, that is, barely lower than that of ASUS. Perhaps she will also come to us for testing.
Memory chips and its volume are exactly the same as all other video cards articles:
The effective frequency in the 3D-mode is not increased relative to the reference and is 6008 MHz, and in general, the characteristics of the EVGA GeForce GTX 660 Ti SuperClocked are as follows:
Under the plastic cover is hidden the standard cooling system:
It is based on an aluminum radiator with a copper base and thick ribs, through which the radial fan runs the stream of air, cooling the graphics processor and the radiator on strength keys:
Everything is simple, inexpensive, and all hot air is thrown out. But is it effective? Check:
I think, the same results as at ASUS DirectCu II, no one waited from the reference cooler, nevertheless, we cannot not note the fact that the EVGA cooling system fully copes with its task: 75 degrees Celsius in automatic operation at 1770 R / min and 54 degrees Celsius at the maximum 3780 rpm.
The acceleration of the graphics processor was not impressed - to the base frequency, we managed to add only to 60 MHz, but the memory was frankly pleased, adding an effective frequency to nominal 1220 MHz:
After overclocking the frequency of the EVGA GeForce GTX 660 Ti SuperClocked video card amounted to 1040/1119/7328 MHz:
In high load mode, the frequency of the graphics processor after overclocking reached 1197 MHz, and its maximum temperature was 78 degrees Celsius:
Obviously, EVGA turned out to be the most common video card with a reference printed circuit board, a cooling system and not highly increased frequencies. Perhaps, Gigabyte will delight with something more attractive?
On the back - information about the features of the product, system requirements and used technologies. Inside a thin colorful shell inserted an additional box of thick cardboard. The separate compartment is assigned to it under the video card, and in another smaller, there are two adapter cables to connect additional power, a CD with drivers and a brief installation instructions:
Gigabyte GeForce GTX 660 Ti Ultra Durable Produced in Taiwan and is already selling for $ 299. A three-year warranty is provided on the video card.
From the two previous Gigabyte products is distinguished by blue textolite and, of course, the cooling system:
The length of the video card with accounting outside the circuit board of the cooling system is 252 mm, the thickness is 39 mm.
The outputs are the same as connectors for SLI and additional power:
The printed circuit board is quite interesting. It would seem that the magnified length of the PCB indirectly tells us about the original design:
But, if you look attentively, Gigabyte uses a reference printed circuit board with a 4 + 2 + 1 power scheme, like EVGA, for example:
On the empty rear of the textolite there are only two power connections, a connector for fans and a pair of small elements. However, Gigabyte talks about using Ultra Durable technology in this model, due to which the graphics processor temperature is 5-10% lower, overclocker potential is 10-30% higher, and electricity saving can reach 30% compared to the reference samples of GeForce GTX 660 Ti. Marketing?
The Gigabyte video card graphics processor is released at the same week as ASUS - in early May:
Its base frequency in 3D mode is increased from the nominal 915 MHz to 1033 MHz, and in the forced mode it may increase to 1111 MHz. In addition, we note that despite not the highest GPU frequency, according to the monitoring data, it is at the Gigabyte video card, we observed the greatest raising of frequency during testing - up to 1229 MHz.
Two GDDR5 gigabytes of memory are typed by the same HYNIX chips, as in the two previous test participants:
Their effective frequency in the 3D-mode is equal to 6008 MHz, that is, not at all increased relative to the reference for GeForce GTX 660 Ti.
Let's look at the Gigabyte GeForce GTX 660 Ti Ultra Durable specification and then we turn to the study of the cooling system:
The original GIGABYTE WINDFORCE 2X cooling system is a lightweight version of the top cooler Gigabyte "Triangle Cool" installed on the video card upper price segment:
The cooler consists of a three-seen aluminum radiator on two copper heat pipes with a diameter of 8 mm and a light plastic frame with two 100-mm fans. The ribs are soldered to the tubes and the base, and for the power elements, a separate copper plate is assigned, which is part of a small radiator section:
The fan rotation speed is automatically adjusted by the PWM method in the range from 1200 to 2550 rpm (according to monitoring data). The original manufacturer of "turntables", the type of bearing and electrical characteristics are unknown.
In the automatic mode of operation of the windforce 2x fans, it coped with its task, by coiling the graphics processor in the peak of the load to 68 degrees Celsius. At the same time, the speed of rotation of the fans increased only to 1620 rpm:
At the maximum 2550 rpm, the cooler cools the graphics processor of the video card for 8 degrees is better at the final 60 degrees Celsius.
When checking the overclocking potential of the Gigabyte GeForce GTX 660 Ti Ultra Durable, the frequency of the graphics processor was increased by 65 MHz, which is higher than the two previous test participants, but still not impressive. But the memory pleased, putting a record of today's article and disperse at 1460 effective megahertz:
As a result, the frequency of the overclocked video card amounted to 1098/1176/7468 MHz:
According to monitoring after acceleration, the frequency of the graphics processor in the load reached 1293 MHz, which is also a record among participants in today's material:
As for the temperature of the graphics processor, after overclocking, it increased only by 3 degrees Celsius, and the speed of the cooling system fans remained at the same level.
Useful information on it is a bit and the whole it seems to us, borrowed from the NVIDIA website. Together with the video card, one cable adapter is supplied to connect the additional power supply, the DVI-TO-D-SUB adapter and the drivers CD:
Country of production - China, warranty - 1 year, retail price - 299 US dollars.
The entire front side of the video card closes the cooling system, which goes a little over the edge of the short circuit board:
The total length of the video card is 203 mm, and the thickness is 42 mm.
The printed circuit board is made on reference design:
Consequently, nothing new or special to say about the flow system of the video card is impossible:
But on the Inno3D installed the most "fresh" graphics processor, released at the junction of June and July of the current year:
The basic frequency of the graphics processor in 3D mode is 915 MHz, in boost mode - 980 MHz, that is, completely standard for GeForce GTX 660 Ti. The same with the memory of the video card, its volume and frequency are identical to the reference and are equal to 2 GB and 6008 MHz, respectively.
Thus, the Inno3D GeForce GTX 660 TI Herculez2000S is the only testing video card, the frequency of which is not higher than the nominal GeForce GTX 660 Ti:
Therefore, interest in this video card can only be the HerculeZ2000S branded cooling system. Compact and lightning it consists of a two-section aluminum radiator on four copper heat pipes with a diameter of 6 mm, two fans in plastic framework, decorative fan linings, as well as a metal plate with thermal stacks on memory chips and power elements:
Note that the radiator's ribs are soldered to heat pipes:
Two 75-mm impeller of the fans are fixed in the plastic framework, the edges of which are engaged in the slits in the side sides of the radiator. The fans are released by Colorful and are based on sliding bearings:
The speed of rotation of the fans is automatically adjusted by the pulse modulation method in the range from 1260 to 3240 rpm. The maximum power consumption of each fan should not exceed 3.4 W.
Let's see how effective Herculez2000S is effective:
The graphics processor warmed up to 71 degrees Celsius in the automatic mode of operation of the fans, when their speed increased to 1680 rpm, and up to 59 degrees Celsius at the maximum 3240 rpm. These are average results for today's testing participants.
The low base frequency of the graphics processor allowed the INNO3D GEFORCE GTX 660 Ti Herculez2000S video card to demonstrate a good overclocking potential. Thus, the core frequency managed to increase by 105 MHz, and video memory - at 980 effective megahertz:
At the same time, the final frequency of the GPU Inno3d was even lower than the basic ASUS and Gigabyte products - only 1020 MHz:
The maximum temperature of the kernel after overclocking the video card was 72 degrees Celsius, and the speed of the fans increased to 1770 rpm:
A good result, given that Inno3D is not so much noise against the background of some other test participants. Go to the next video card review.
Along with the video card, two adapter cables are supplied for additional power, adapter DVI-TO-D-Sub, Driver CDs, Installation Instructions and Advertising Booklet:
The video card produced in China, worth 299 US dollars, is provided a two-year warranty.
Against the background of the three previous KFA2 video cards, GeForce GTX 660 Ti Ex OC looks great, more resembling the GeForce GTX 680 than on GTX 660 Ti. Its length is 255 mm:
On the output panel we can only mark the sparse grille:
Mio connectors for SLI-ligaments here are the same as on all other test cards, but with food KFA2, I decided not to notice, and instead of two six-pin connections installed eight and six-contact connections:
At the same time, the requirements for the power supply for a system with one such video card remained the same - 450 watts.
After removing the cooling system, it becomes clear that in front of us - the circuit board from the original KFA2 GeForce GTX 680 Ex OC:
On the nutrition of the graphics processor, five phases are reserved immediately, two more - on video memory:
The Richtek RT8802A controller is responsible for controlling the power of the graphics processor. Obviously, the power circuit in this way should contribute to more successful acceleration and stability at high frequencies. Check.
Externally, the graphical processor of the KFA2 GeForce GTX 660 Ti EX OC video card is different from the above-mentioned marking week of release:
Internally - only the frequency that is 1006 MHz in the base mode, and in the forced - 1085 MHz. This is the average result among other video cards of the material.
KFA2's memory decided not to overclock, leaving regular 6008 MHz, but increased its volume from two to three gigabytes. At the same time, the same HYNIX chips are used here as on all other video cards:
Thus, the KFA2 GeForce GTX 660 TI EX OC specification is as follows:
The original video card cooling system has no own name, but it does not diminish its advantages. This is a massive nickel-plated design with a copper base, four 8 mm thermal tubes and thin aluminum plates:
All places of conjugation places are registered, and even simply visually here it is not difficult to determine that the KFA2 radiator area is the largest among all today's cooling systems:
Two 92-mm impeller are installed in the plastic framework, which are brought to the metal casing. Fan manufacturer is Everflow:
In the fans, a sliding bearing with an increased service life (EBR) is applied. Depending on the temperature of the graphics processor and the load on the video card, the PMW adjustment can change the speed of rotation of the fans in the range from 1100 to 3100 rpm.
KFA2 GeForce GTX 660 TI EX OC has demonstrated the highest cooling efficiency both in the automatic mode of fan speed adjustment and in maximum speed mode:
The graphics processor warmed up only 60 degrees Celsius at the speed of 1620 rpm fans and only up to 49 degrees at the maximum 3090 rpm. This is the best result among all eight video cards.
Unfortunately, such an effective cooling system and enhanced printed circuit board did not contribute to the high acceleration potential of the video card. We were able to cross the graphics processor only at 50 MHz, and the video memory by 1300 MHz:
The final frequencies amounted to 1056/1135/7308 MHz:
According to the monitoring data after the acceleration of the video card, the frequency increased to 1187 MHz, however, the temperature mode of operation KFA2 GeForce GTX 660 TI EX OC, due to the highly efficient cooling system, has not changed:
All the same 60 degrees Celsius with automatic adjustment of the rotational speed of the fans. An interesting product turned out to be at KFA2, now let's get acquainted with the offer of MSI.
On the front side of very bright packaging, all basic information about the product is provided, including support for triple stress control and improved PWM control:
On the reverse side of the packaging, detailed video card specifications are given, minimum system requirements and key features on two dozen languages.
Along with the video card, two adapter cables for additional power supply are supplied, one DVI-TO-D-Sub Adapter, a CD with Drivers and Utilities, Installation Instructions, as well as a MSI advertising booklet:
A video card is produced in China and costs 299 US dollars. The warranty period is equal to three years.
Like Asus, MSI video cards are easily recognizable externally, thanks to the branded TWINFROZR cooling system and stylish design:
Note that MSI N660TI PE 2GD5 / OC TWINFROZR IV is the second in length of the video card testing - 257 mm. This must be considered if you plan to assemble the game system in a close building. The thickness of the video card is only 37 mm.
The standard set of outputs in the form of DVI-I and DVI-D (Dual-Link), HDMI and DisplayPort gives GeForce GTX 660 TI with simultaneous support for four monitors, and the MSI video card in this sense is no exception:
Additional power and SLI connectors are identical to the reference, but the printed circuit board at MSI its own development:
In the power part we can see five phases of the function of the graphics processor, two phases on video memory and one on the power chain:
Moreover, in the design of the printed circuit board, only high-quality durable components of the Military Class III class are used, using Hi-C capacitors with a tantalum core, SFC chokes and condensers with Dark Solid Cap solid-state electrolyte. All this, according to MSI, will allow overclockers to squeeze "all juices" from GK104.
The graphics processor is released at the same week as the crystals of ASUS and GIGABYTE video cards:
The nominal frequency for the 3D-mode is 1020/1098 MHz, but according to the monitoring data increased to 1176 MHz. That is pretty good factory overclocking. But the amount of memory (2 GB) and its frequency (6008 MHz) are standard, as well as the HYNIX microcircuits used:
Let's look at the MSI N660TI PE 2GD5 / OC specification and then turn to the cooling system TWINFROZR IV:
The original MSI cooler is already well familiar to our regular readers, since his company establishes on many of its other models of video cards that we tested earlier. In its basis, an aluminum radiator on four copper nickel-plated heat pipes with a diameter of 8 mm, leaving copper base:
It features two fans closed on top of a metal casing. To cool the memory chips and power keys, a metal plate with thermal layers is used. Skink was used in the radiator.
The fans with a diameter of 80 mm are released by POWER Logic (model - PLD08010B12HH) and are based on a double rolling bearing:
This is not the best choice in terms of noise level, but ideal in terms of durability. Nevertheless, MSI declares about 17.1 dB gains noise level and about a 14-degree advantage over temperature in comparison with the reference cooler. With the temperature TWINFROZR IV really copes well:
70 degrees Celsius with automatic adjustment (1620 rpm) and only 55 degrees Celsius on the kernel at the maximum power of the fans (4170 rpm). What is there and the rest of the coolers with the level of noise, we will learn a little later.
When checking the overclocker potential, the video card found out that the frequency of the graphics processor can be listed without loss in stability and image quality, and the video memory frequency is 1160 MHz:
As a result, the acceleration of the GPU MSI N660TI PE 2GD5 / OC took second place of eight testing video cards, and the final frequencies amounted to 1110/1188/7168 MHz:
After overclocking the temperature of the nucleus in the load increased by 3 degrees Celsius at the final 73 degrees and 1740 rpm of two twinfrozr iv fans:
The peak of the kernel during tests according to the monitoring data reached 1266 MHz. It cannot be said that the MSI product calls "a storm of positive emotions", but in general it is quite a good and attractive for the buyer of the video card. However, do not rush to run to the store, we have the next participant and comparative charts in the queue.
We see the design of the back of the box today for the third time - not all designers bother themselves fantasy. But the Palit the top cover of the box is open, opening out the potential buyer and the video card itself and comprehensive information about it:
Complete set without findings: two adapters, power cable and drivers drive:
The homeland product is "subwayen", the cost is 299 US dollars and one year warranty.
The jetstream-design of Palit products are also easily recognizable. The plastic casing with two transparent fans and the hieroglyph between them is remembered at a glance:
The length of the video card is small - only 245 mm, but the thickness is more than the remaining seven video cards and is 49 mm. Thus, use this model in SLI mode when the PCI-Express location is located on the Motherboard "through one".
Two six-contact connections for additional nutrition, two MIO connectors and outputs here are standard:
We see the video card with a printed circuit board today in the fourth time - this is a copy of reference design:
At the same time, several other batteries are installed on Palit than on EVGA or INNO3D, although the phase configuration remained the same: "4 + 2 + 1":
The graphics processor A2 revision, as well as all the other GPUs, released in Taiwan on the 28-nm technical process and dated 13th week 2012 (March-April):
Its base frequency is 1006 MHz, forced - 1085 MHz, which according to monitoring data and at high load reaches 1150 MHz.
Unlike all the video cards discussed above, their two gigabytes of memory in Palit decided to disperse. True, it was embarrassed with overclocking and added to the rated frequency of 6008 MHz, only 100 MHz at the final 6108 MHz. To use some other chips, a clear case, it did not need - here are all the same chips HYNIX H5GQ2H24AFR R0C:
Specifications Palit GeForce GTX 660 Ti Jetstream are shown in the GPU-Z screenshot:
The video card is set exactly the same cooling system as on Palit GeForce GTX 670 JetStream With an aluminum radiator on three copper thermal tubes with a diameter of 6 mm and a plastic casing with two fans:
On the power elements a high aluminum radiator with thermal block laying is installed.
Fans, like MSI, released Power Logs and are labeled PLA09215S12H:
Thanks to the support of PWM control, they can rotate at a speed of 900 to 2900 rpm.
The temperature mode of the video card is not very different from other test participants: 71 degrees Celsius in automatic mode of operation of fans and only 55 degrees Celsius at maximum speed:
Despite the use of the reference printed circuit board, the lack of newcomer technologies and not a record cooling system, our instance of the Palit GeForce GTX 660 Ti Jetstream accepted the kernel at 135 MHz (the best result), and on video memory - by 1200 MHz, which is also quite good:
The frequencies of the video card after overclocking amounted to 1141/1220/7308 MHz:
Moreover, in the 3D load, the peak frequency of the graphics processor was held at a level of 1285 MHz, which is only below Gigabyte:
But the temperature after overclocking the video card, in our opinion, is still high - 77 degrees Celsius at 1470 rpm.
Go to the last test participant - the product of ZOTAC product.
The video card is sealed in the mid-sized cardboard box, on the front side of which the model, memory, the DIRECTX 11 support and other technologies, the extended warranty and the DUAL SILENCER cooling system are indicated:
On the back of the box schematically drawn the video card itself and individual icons indicate that its 10 degree Celsius cooling system is more efficient and for 10 dB quische with the GeForce GTX 660 Ti reference cooler, plus what amp! EDITION is 10% faster. The following are key features of the video card, various NVIDIA technologies and minimal system requirements are still listed.
The video card package includes two adapter cables to connect the power supply, DVI-TO-D-SUB adapter, a CD with drivers, utilities and software, brief and complete installation instructions, as well as a coupon for downloading the game Trackmania 2:
The video card is produced in China and is recommended for sale for 299 US dollars, that is, exactly for the same money as the reference GeForce GTX 660 Ti 2 GB. ZOTAC provides its video card with a so-called extended warranty for a period of 3 years.
Zotac GeForce GTX 660 Ti Amp! EDITION The most compact video card testing is its size constitute only 191x100x37 mm:
We have the fifth and last reference design of the printed circuit board:
Here, as in other four cases, "references", four phases of the graphics processor and two phases of the video memory:
The graphics processor GK104 A2 revision is released again in Taiwan, and again at the 18th week of 2012:
The basic frequency of the ZOTAC graphics processor in 3D mode is 1033 MHz (1111 MHz - in forced mode), which is immediately 118 MHz above the base frequency of the reference GeForce GTX 660 Ti. According to monitoring data, the GPU frequency increased to 1215 MHz. We add that when switching to 2D mode, the frequency is reduced to 324 MHz at a voltage of 0.987 V.
HYNIX memory microcircuits with exactly the same label, as with all other testing video cards:
However, unlike other participants, ZOTAC GeForce GTX 660 Ti Amp! EDITION The effective memory frequency is 6608 MHz. This should give odds to the ZOTAC product in the resource-intensive modes using smoothing. Check tests.
Let's look at the characteristics of this video card:
On Zotac GeForce GTX 660 Ti Amp! Edition, as well as on the usual version of this video card, the original DUAL SILENCER cooling system is installed with three copper thermal tubes with a diameter of 6 mm:
On a compact aluminum radiator with thin ribs, two 70mm fans are installed, closed with metal casing:
Fans are released under the Apistek label and are labeled GA81S2U. The speed of their rotation is controlled automatically by pulse modulation (PWM) in the range from 1100 to 3500 rpm.
The maximum power consumption of each such fan should not exceed 4.6 W.
Check the effectiveness of Dual Silencer on an overclocked ZOTAC GeForce GTX 660 TI AMP factory! Edition:
In general, it is not bad, although before the records of today's test are distant: 71 degrees Celsius in automatic mode and 65 degrees Celsius at maximum fan power.
As with all other testing participants, the overclocking potential of the ZOTAC video card was studied with the maximum Power Limit value, which is 123% for this video card. The GPU frequency of the video card managed to raise by 65 MHz, and the video memory only on 260 effective megahertz, which, alas, is the worst test results:
The final frequencies of the video card amounted to 1098/1176/6868 MHz:
The maximum frequency of the graphics processor in 3D mode after acceleration according to the monitoring data was 1280 MHz:
The GPU temperature increased to 72 degrees Celsius at a fan speed of 2490 rpm. It's time to tell about the noise level of all video cards of testing, as well as look at the summary temperature charts and the frequency table.
Let's see what happened on schedule and table:
Obviously, the most quiet is the Cooling system DirectCu II ASUS video card, and this is confirmed by a subjective assessment of the noise level. In second place - the cooler Zotac Dual Silence, but the general group of the rest of the video cards he won quite a bit. Also note for a very high noise level of the cooling system Palit Jetstream and the reference EVGA video card cooler. The remaining video cards are approximately the same by noise level.
However, you should not forget that with automatic adjustment of the speed of rotation of the coolers, they achieved different speeds, so it would be useful to note on the schedule of their border of the work, which we always and make in articles about video cards. But since today we immediately have eight video cards, then an unreadable meal would be on the chart. Therefore, we did somewhat differently, making the noise level in the automatic mode of operation of the coolers and at their maximum speed to a separate diagram and adding these results with data on the maximum graphics processor temperature. Video cards in the diagram in each mode testing are sorted in ascending order of noise level. We look:
In automatic operation, the ASUS GeForce GTX 660Ti DirectCu II Top video card operates in automatic operation, which is not surprising at its maximum 1440 rpm. At the same time, the ASUS video card ranked third at the maximum graphics processor temperature. Impressive result! Next, with a decent difference in noise, a dense group of video cards INNO3D, MSI and KFA2 is underway, among which the latest video card is allocated with its cooling efficiency. Its cooler is generally the best among all eight video cards of the article. Following with a small lag behind, Gigabyte and EVGA video cards are followed, and the reference cooler is quite naturally the outsider in efficiency. Well, more than all the Palit and ZOTAC products are no longer the automatic mode.
At the maximum fan speed, the picture has changed. In terms of noise, the leaders came out by the Gigabyte video card, and ASUS moved to second place, while at the same time bypassing Gigabyte by 6 degrees Celsius at peak graphics processor temperature. ZOTAC from an outsider turns into one of the leaders, although the temperature of this video card is the highest at the maximum speed of rotation of the fans. Standing from ZOTAC Only 0.1 dBA, the Cooling Cooling System INNO3D cools the graphics processor for 6 degrees Celsius is better. True, you should not forget about the difference in the GPU frequencies. The KFA2 product is again located "in the middle of the peloton", and again leads the temperature. The remaining tripler from EVGA, MSI and Palit demonstrates the practical equal noise level results and temperatures.
Next, we brought into a separate table all the frequencies of video cards in the nominal mode of their work and after overclocking. The best results are marked in red, the worst - blue:
Interestingly, despite the highest factory frequencies, the ASUS video card did not demonstrate the maximum frequency in the load (according to the monitoring data). The leader in this indicator was the Gigabyte video card. The Palit product demonstrated the highest potential of the kernel overclocking, but in the load, the frequency of Gigabyte again turned out to be slightly higher. Note that the Power Limit at Gigabyte is not the highest, however, it is from this card that the GPU frequency in the load rises above the rest. In addition, Gigabyte has a better memory of everyone. The worst core acceleration turned out to be an Inno3D video card, and on the acceleration of video memory - ZOTAC.
Now the temperature of the graphic processors of video cards in acceleration and the noise level of their cooling systems with automatic adjustment mode to one diagram, sorting the video card from top to bottom in the order of increasing noise levels:
As before, the leader in the noise level after overclocking video cards remained the ASUS product, and it also belongs to the second place at the temperature of the graphics processor. But the first with a huge 10-degree advantage is the KFA2 video card. This video card has a really most effective cooler, and thanks to him KFA2 was able to rise to second place in terms of noise. Following a dense group from Inno3d, MSI and Gigabyte products. They demonstrate not only almost the same noise level, but also the temperature of graphics processors. True, you should not forget about the frequencies that MSI and Gigabyte are higher than that of INNO3D. The remaining Trinity from the ZOTAC video cards, Palit and EVGA is noise above 50 dBA, but if ZOTAC holds the temperature of the graphics processor at the level of other higher testing participants, then Palit and EVGA are not possible, they lose 5..6 degrees Celsius. Go ahead.
Let's see what we did:
The difference in power consumption of systems with eight original GeForce GTX 660 Ti is not significant. From the general range, the instance of ZOTAC is embossed, apparently due to the increased frequency of the video memory. In all other cases, the difference is laid in 10-12 watts, which, with the overall power consumption of the system, about 400 watts does not play any role. We dare to assume that all the statements of manufacturers about the economy of their video cards against the background of competitors are no more than marketing tricks. As for the arched GeForce GTX 660 TI performed by Gigabyte, the power consumption of the system with it 14 watts is higher than in the nominal mode of operation, and almost reaches the level of Gigabyte GeForce GTX 670. Maximum consumption demonstrates the system with Sapphire Radeon HD 7950, stacking anyway 450 watts.
In addition to video cards from a review in testing, we have added two more video cards: Gigabyte GeForce GTX 670 Ultra Durable 2 GB and Sapphire Radeon HD 7950 Dual-x 3 GB with the latest version of BIOS:
As we see, the frequencies of these video cards are raised relative to the nominal, but we did not reduce them to the reference layer, since almost all the GeForce GTX 660 Ti are tested today have increased frequencies.
To reduce the dependence of the video card performance from the platform speed, 32-nm a six-core processor with a multiplier 37, a support frequency of 125 MHz and the activated "Load-Line Calibration" function was overclocked to 4.625 GHz with raising voltage in the motherboard BIOS to 1.49 V:
Hyper-Threading technology is activated. At the same time, 16 GB of RAM was functioned at a frequency of 2 GHz with timings of 9-11-10-28 at a voltage of 1.65 V.
Testing started on September 14, 2012 was conducted under the Microsoft Windows 7 Ultimate X64 SP1 operating system with all critical updates to the specified date and with the installation of the following drivers:
Since we have 10 video cards in tests today, then their performance we have checked only in one resolution of 1920x1080 pixels. However, two chart quality modes were still used for tests: "Quality + AF16X" - the quality of the textures in the default drivers with the inclusion of anisotropic filtering level 16x, and "Quality + AF16X + MSAA 4x (8x)" with inclusion Anisotropic filtering of the level 16x and full-screen smoothing of degrees 4X or 8X, in cases where the average number of frames per second remained high enough for a comfortable game. The inclusion of anisotropic filtering and full-screen smoothing was performed directly in the game settings. If these settings in the games were absent, then the parameters changed in the Catalyst and GeForce drivers control panels. It also disabled vertical synchronization. No more changes in the driver settings were made.
The list of test applications was reduced to one semi-synthetic package and 7 the most recent and resource-intensive games updated to the latest versions (at the start date of tests). That's what it looks like:
We add that if the game implements the possibility of fixing the minimum number of frames per second, it also reflected in the diagrams. Each test was performed twice, the final result was made the best of the two values \u200b\u200bobtained, but only if the difference between them did not exceed 1%. If the deviations of the tests exceeded 1%, then testing was repeated at least at least once to get a reliable result.
3dMark 2011.
Despite the proximity of the frequencies of the majority of GeForce GTX 660 Ti, in the "Performance" settings mode, we can observe a noticeable variation of the results. Moreover, it is also leading not the products of ASUS or ZOTAC, which have the highest core and memory frequencies, respectively, and Gigabyte. Probably, it is the maximum peak frequency of a graphics processor, which at the Gigabyte GeForce GTX 660 Ti Ultra Durable is the highest, allowed this video card to escape into leaders. The last place among GeForce GTX 660 Ti quite naturally occupied the InnO3d product, whose frequencies are equal to the reference. In the "Extreme" settings mode, the difference between video cards is leveled, but Gigabyte and Zotac are still slightly faster than everyone else.
Metro 2033: The Last Refuge
In Metro 2033: The Last Refuge the difference in the performance of all eight GeForce GTX 660 Ti is either absent or is 1-2 frames per second. Mathematically, the leadership belongs to ZOTAC, yet the factory overclocking the video memory of this video card was not in vain. Note that Radeon HD 7950 in this game is ahead of all GeForce GTX 660 Ti and even a slightly overclocked GeForce GTX 670. Sense from the additional gigabyte video memory of the KFA2 product.
Total War: Shogun 2
Minimal difference between GeForce GTX 660 Ti and in the game Total War: Shogun 2. Only in the mode without using smoothing, we can observe a slight spread of the results. The slowest reappears inno3d, and the fastest - Gigabyte and Zotac. Related GeForce GTX 660 Ti is not inferior to Gigabyte GeForce GTX 670 Ultra Durable, and 3 GB of video memory on KFA2 again do not bring effect.
Crysis 2.
The same picture is repeated in the game CRYSIS 2:
Battlefield 3.
A slightly larger scatter of the results of GeForce GTX 660 Ti We can observe in the game Battlefield 3, but the leaders and outsider remained the same. Three gigabytes of memory on KFA2 in these test modes do not bring additional productivity growth in comparison with conventional two-scale GeForce GTX 660 Ti.
Nexuiz
In the test game Nexuiz, only ZOTAC product was able to stand out on a general background of the results of GeForce GTX 660 Ti, and Gigabyte rates closer to the bulk of these video cards. It is impossible not to note the overwhelming superiority of the Radeon HD 7950 in this game created with the support of AMD, by the way.
Sniper Elite V2 Benchmark
In the Sniper Elite V2, the difference between the original GeForce GTX 660 Ti can only be seen in the mode without using smoothing, where ZOTAC and Gigabyte is once a little faster than the remaining video cards. As for the mode with the use of supersembling, the difference in performance does not exceed 1-2 frames per second. At the same time, all the video cards are tested today on NVIDIA graphics processors much slower than Sapphire Radeon HD 7950.
Sleeping Dogs.
Not knocked out of the general range and test results in the game Sleeping Dogs.
We apply the outcome to the charts, and go to the conclusion.
ASUS GeForce GTX 660Ti DirectCu II Top is the best choice of all the tested GeForce GTX 660 Ti, in our opinion. And the case is not at all in the highest frequency of the graphics processor, but in a very quiet and fairly efficient cooling system capable of satisfying both the most demanding level of the noise of Estet and overclockers. The latter will also have a reinforced printed circuit board with a high-quality element database and a three-year warranty. The poor equipment of the video card does not correspond to its status, but this moment is still not critical when choosing.
EVGA GeForce GTX 660 Ti SuperClocked is a reference with a slightly increased frequency of the graphics processor. As if we did not respect the company EVGA, but today's round she lost, taking only the last eighth place. Noisy and relatively ineffective cooler, simple reference PCB and unbearable indicators when accelerating and in performance tests. All this does not allow us to recommend this video card to purchase. Isn't EVGA already removed this model from production, replacing for more interesting modification of FTW?
Gigabyte GeForce GTX 660 Ti Ultra Durable - did not hit the face of Gigabyte in today's review and testing. Like all the other six dough participants, it loses in terms of noise and efficiency asus product, but lags behind quite a bit. In addition, in the tests of Gigabyte, all other video cards are consistent with the exception of ZOTAC. Perhaps we would give the Gigabyte third place in today's material.
Inno3D GeForce GTX 660 Ti Herculez2000s is another model with a reference printed circuit board. However, unlike EVGA, Inno3D engineers equipped their video card with the original cooling system, and, judging by the results demonstrated by it, it turned out quite well. But the frequencies they have forgotten the factory, but it would be quite high, because inno3d GeForce GTX 660 Ti Herculez2000s turned out to be the only video card in an article with rated frequencies.
KFA2 GeForce GTX 660 Ti Ex OC 3 GB is primarily a video card with a stunningly efficient cooler. Even a reinforced printed circuit board, which is a copy of the flagship GTX 680 EX OC, is moving into the background when the original KFA2 cooler will "brings" all other test participants 10 degrees Celsius at the maximum temperature of the graphics processor. In addition, the increased frequency of the GPU and the moderate noise level, the final second place on the combination of noise and temperatures after acceleration of video cards allow us to give the second after the ASUS space of the KFA2 video card.
MSI N660TI PE 2GD5 / OC TWINFROZR IV - nothing bad we cannot say about the MSI video card. It is a very high-quality product with an expensive and reliable element base, an effective cooler, an increased frequency of graphics processor and in addition stylishly looking. The bonus in the form of a system for removing dust from the cooler and is completely unique. MSI N660TI PE 2GD5 / OC TWINFROZR IV is a bit more tricking, a little quickly and a droplet is more effective, it would be quite able to get around Gigabyte or even ASUS. We recommend buying, but still only in the absence of test leaders.
Palit GeForce GTX 660 Ti Jetstream - and newly reference circuit board, original cooler and increased graphics processor frequencies and even memory. However, it is the high level of noise of the cooling system JetStream, it does not allow us to recommend this model to the acquisition. The company's engineers should still work on a plastic casing in which fans are fixed to reduce the noise-produced and make a video card more attractive from this point of view. At the same time, we recall that it was Palit today who today demonstrated the highest overclocking potential of the GPU.
Zotac GeForce GTX 660 Ti Amp! EDITION - The smallest video card material turned out to be the fastest amount of all tests. Due to the significantly increased memory frequency and the core frequency at the level of video cards of other manufacturers, ZOTAC was able to beat all the other GeForce GTX 660 Ti. But in terms of cooling efficiency and noise level, ZOTAC leaders have not yet reached. Perhaps, just released version of AMP! EXTREME EDITION will be able to achieve this? We'll see. And we have everything today.
Specifications
Features of all eight original GeForce GTX 660 TI video cards are given in the following table:Well, now we will study in detail each of them.
ASUS GeForce GTX 660 TI DirectCu II TOP 2 GB (Ti-DC2T-2GD5)
The new ASUS Top series video card comes in a large and colorful decorated box with traces of someone's claws on the front side:
They also provide basic information about the video card extended on the back of the box. Equipment, surprisingly poor - only fast installation instructions and DVI-TO-D-SUB adapter:
Probably, the cables for connecting additional power and the CD with drivers and the ASUS brand utilities are lost somewhere on the road. ASUS GeForce GTX 660 Ti Directcu II Top in China is available and costs $ 309, which is only $ 10 more expensive GeForce GTX 660 Ti reference samples. A three-year warranty period is provided on the video card.
The ASUS video card design is easily recognizable by the referring system DirectCu II closing the entire front side. The card looks stylish, but strictly:
Due to the Couple Circuit Coupling Course, the length of the video card is 269 mm, and this is the longest GeForce GTX 660 Ti of today's testing. At the same time, the thickness of the ASUS GeForce GTX 660 TI DirectCu II TOP is 38 mm, that is, no three slots it blocks, such as, for example, flagship GTX 680.
The video card is equipped with a standard set of outputs: DVI-I and DVI-D (Dual-Link), HDMI and Displayport, combined with a lattice for partial emission of a heated aircraft aircraft outside the system unit housing:
Two MIO connectors for creating 2-, 3- and 4-way SLI configurations and two six-pin connections for connecting additional power are installed in familiar to GeForce GTX 660 TI places:
Looking forward, we note that almost all other video cards of today's review have the same configuration of these connector pairs, with the exception of one product, which we will definitely say separately. Therefore, we will not stop more in this moment in the overwhelming majority of cases. We add that the recommended power of the power supply unit for a system with one such video card is 450 watts.
Asus has traditionally pleases overclocking lovers and gives its product a unique printed circuit board with a reinforced power supply system:
Six phases are allocated on the graphics processor, two, and on the power supply chain - one phase:
The proprietary digital Digi + Power supply system with the Super Alloy Power technology, which assumes the use of only high-quality and durable components, allows 30% to reduce the vendors, increase energy efficiency by 15% and extend the service life in comparison with the reference products by 2.5 times. It's great that the technologies previously used by ASUS only in HI-END products are gradually becoming accessible and transferred to the medium price segment video cards.
The graphics processor of our ASUS GeForce GTX 660 TI DirectCu II Top instance is released in Taiwan at week 18 of the current year (beginning of May), and refers to A2 revision:
Since the GK104 configuration on the GTX 660 TI has already been studied earlier, then in today's article we will emphasize your attention on changes in terms of graphics processors of video cards. And then Asus did not hit the dirt face - its graphics processor operates at 1059 MHz in conventional 3D-mode and at 1137 MHz - in forced. This, immediately say, the record frequency of the graphics processor is not only among the eight video cards of the material, but also in general all the serial-produced GeForce GTX 660 Ti.
ASUS GeForce GTX 660 TI DirectCu II Top is equipped with eight GDDR5 memory chips in FCBGA packaging with a total volume of 2 GB issued by Hynix Semiconductor Inc.:
Marking microcircuits - H5GQ2H24AFR R0c, the theoretical efficient frequency of operation is 6000 MHz, on which memory and functions. Thus, with a bus width of 192 bits, the memory bandwidth is equal to the reference for GeForce GTX 660 Ti and is 144.2 GB / s. All today's testing video cards are equipped with chips with the same labeling, but not all functioning at the same efficient frequency.
Final Specifications ASUS GeForce GTX 660 TI DirectCu II Top:
In addition to a unique printed circuit board, ASUS is ready to please and lovers of effective and, importantly, quiet cooling. Of course, the company's branded cooling system ASUS DirectCu II:
It consists of an aluminum radiator on three copper 8-mm heat pipes with direct contact and aluminum casing with two fans:
On the power elements, an additional aluminum radiator with thermal block laying, covered by an air flow of one of the fans.
Two 75 mm impeller issued by Firstd and equipped with PWM control:
The speed of their rotation is adjusted by the video card automatically in the range from 1000 to 3500 rpm. The maximum power consumption of each fan should not exceed 4.2 W.
Hereinafter, to check the temperature mode of the video card as a load, we used five test cycles. Very resource-intensive game Aliens VS. Predator (2010) with the maximum quality of graphics in the resolution of 2560x1440 pixels with anisotropic filtering level 16x, but without the use of smoothing to load the graphics processor to the maximum. Program was used to monitor temperatures and other parameters MSI Afterburner version 2.2.3 And the GPU-Z utility version 0.6.4. All tests were conducted in a closed system block case, the configuration of which you can see in the next section of the article, at room temperature 20 degrees Celsius. All video cards disassembled before testing, so after the assembly were tested on the same thermal interface on the graphics processor - the thermal pump of Arctic MX4.
We look at the temperature mode of ASUS GeForce GTX 660 TI DirectCu II TOP:
Total: 69 degrees Celsius in automatic mode of operation of fans and only 54 degrees Celsius at their maximum speed. These are excellent results, especially considering the increased frequency of the graphics processor. In addition, we advise special attention to pay for the maximum fan speed with automatic adjustment - only 1440 rpm. But, about the noise level we will talk a little later.
Overclocking potential of all video cards we studied at rated graphics processor voltage. When overclocking ASUS GeForce GTX 660 TI DirectCu II TOP did not demonstrate some outstanding results. Without loss in stability and as an image, the basic frequency of the graphics processor was possible to increase only by 50 MHz, and the video memory is 960 effective megahertz:
As a result, the frequency of the ASUS video card amounted to 1109/1187/6968 MHz:
Not the best, but not the worst overclocking result among all eight testing video cards. But the temperature mode of the video card and noise level may envy any other manufacturer:
Total 70 degrees Celsius in the peak of the load at the speed of fans 1410 rpm. Note that the peak frequency of the graphics processor according to the monitoring data was 1239 MHz.
Let's see what other manufacturers can surprise us.
EVGA GeForce GTX 660 Ti SuperClocked 2 GB (02G-P4-3662-KR)
EVGA GeForce GTX 660 Ti SuperClocked Sealed in a small cardboard box, decorated in EVGA products and therefore easily recognizable:
From the packaging features, select a plastic window with which you can refer to the serial number on the package and directly on the video card printed circuit board:
The equipment is not as an example of the richer ASUS product and includes everything you need to connect and operate the video card, as well as bonuses in the form of stickers and a huge calendar poster:
The video card is produced in China and costs $ 309. Warranty - three years.
Even glanced at Evga GeForce GTX 660 Ti SuperClocked, you understand that this is a copy of the reference product:
Only the inscription on the plastic casing indicates that the video card is produced under the EVGA label. Outputs, of course, standard, but closed with plastic caps, and the grille is cut and is supplemented with additional slots to the maximum:
A short printed circuit board, released on reference design, well-known to our regular readers:
Under the high aluminum radiator, the batteries are hidden according to the "4 + 2 + 1" scheme (GPU + MEM + PLL) running the ON SEMICONDUCTOR NCP5392P controller:
The crystal protected by the steel frame of the graphics processor is released a week later the GPU ASUS video card - 19 week 2012:
Audit, marking and configuration do not differ. The base frequency in 3D mode is 980 MHz, in boost mode - 1059 MHz. This is the most modest acceleration among all other testing video cards. By the way, while we prepared this material, EVGA removed from the production of the EVGA GeForce GTX GTX 660 Ti SuperClocked video card, replacing it on a more high-speed FTW version with frequencies 1046/124 MHz, that is, barely lower than that of ASUS. Perhaps she will also come to us for testing.
Memory chips and its volume are exactly the same as all other video cards articles:
The effective frequency in the 3D-mode is not increased relative to the reference and is 6008 MHz, and in general, the characteristics of the EVGA GeForce GTX 660 Ti SuperClocked are as follows:
Under the plastic cover is hidden the standard cooling system:
It is based on an aluminum radiator with a copper base and thick ribs, through which the radial fan runs the stream of air, cooling the graphics processor and the radiator on strength keys:
Everything is simple, inexpensive, and all hot air is thrown out. But is it effective? Check:
Automatic mode Maximum power
I think, the same results as at ASUS DirectCu II, no one waited from the reference cooler, nevertheless, we cannot not note the fact that the EVGA cooling system fully copes with its task: 75 degrees Celsius in automatic operation at 1770 R / min and 54 degrees Celsius at the maximum 3780 rpm.
The acceleration of the graphics processor was not impressed - to the base frequency, we managed to add only to 60 MHz, but the memory was frankly pleased, adding an effective frequency to nominal 1220 MHz:
After overclocking the frequency of the EVGA GeForce GTX 660 Ti SuperClocked video card amounted to 1040/1119/7328 MHz:
In high load mode, the frequency of the graphics processor after overclocking reached 1197 MHz, and its maximum temperature was 78 degrees Celsius:
Obviously, EVGA turned out to be the most common video card with a reference printed circuit board, a cooling system and not highly increased frequencies. Perhaps, Gigabyte will delight with something more attractive?
Gigabyte GeForce GTX 660 Ti Ultra Durable 2 GB (GV-N66TOC-2GD)
The Gigabyte box is again depicted by the Eye of the Decepticon, next to which information about the video card model, the cooling system, the volume of video memory and acceleration is given:
On the back - information about the features of the product, system requirements and used technologies. Inside a thin colorful shell inserted an additional box of thick cardboard. The separate compartment is assigned to it under the video card, and in another smaller, there are two adapter cables to connect additional power, a CD with drivers and a brief installation instructions:
Gigabyte GeForce GTX 660 Ti Ultra Durable Produced in Taiwan and is already selling for $ 299. A three-year warranty is provided on the video card.
From the two previous Gigabyte products is distinguished by blue textolite and, of course, the cooling system:
The length of the video card with accounting outside the circuit board of the cooling system is 252 mm, the thickness is 39 mm.
The outputs are the same as connectors for SLI and additional power:
The printed circuit board is quite interesting. It would seem that the magnified length of the PCB indirectly tells us about the original design:
But, if you look attentively, Gigabyte uses a reference printed circuit board with a 4 + 2 + 1 power scheme, like EVGA, for example:
On the empty rear of the textolite there are only two power connections, a connector for fans and a pair of small elements. However, Gigabyte talks about using Ultra Durable technology in this model, due to which the graphics processor temperature is 5-10% lower, overclocker potential is 10-30% higher, and electricity saving can reach 30% compared to the reference samples of GeForce GTX 660 Ti. Marketing?
The Gigabyte video card graphics processor is released at the same week as ASUS - in early May:
Its base frequency in 3D mode is increased from the nominal 915 MHz to 1033 MHz, and in the forced mode it may increase to 1111 MHz. In addition, we note that despite not the highest GPU frequency, according to the monitoring data, it is at the Gigabyte video card, we observed the greatest raising of frequency during testing - up to 1229 MHz.
Two GDDR5 gigabytes of memory are typed by the same HYNIX chips, as in the two previous test participants:
Their effective frequency in the 3D-mode is equal to 6008 MHz, that is, not at all increased relative to the reference for GeForce GTX 660 Ti.
Let's look at the Gigabyte GeForce GTX 660 Ti Ultra Durable specification and then we turn to the study of the cooling system:
The original GIGABYTE WINDFORCE 2X cooling system is a lightweight version of the top cooler Gigabyte "Triangle Cool" installed on the video card upper price segment:
The cooler consists of a three-seen aluminum radiator on two copper heat pipes with a diameter of 8 mm and a light plastic frame with two 100-mm fans. The ribs are soldered to the tubes and the base, and for the power elements, a separate copper plate is assigned, which is part of a small radiator section:
The fan rotation speed is automatically adjusted by the PWM method in the range from 1200 to 2550 rpm (according to monitoring data). The original manufacturer of "turntables", the type of bearing and electrical characteristics are unknown.
In the automatic mode of operation of the windforce 2x fans, it coped with its task, by coiling the graphics processor in the peak of the load to 68 degrees Celsius. At the same time, the speed of rotation of the fans increased only to 1620 rpm:
Automatic mode Maximum power
At the maximum 2550 rpm, the cooler cools the graphics processor of the video card for 8 degrees is better at the final 60 degrees Celsius.
When checking the overclocking potential of the Gigabyte GeForce GTX 660 Ti Ultra Durable, the frequency of the graphics processor was increased by 65 MHz, which is higher than the two previous test participants, but still not impressive. But the memory pleased, putting a record of today's article and disperse at 1460 effective megahertz:
As a result, the frequency of the overclocked video card amounted to 1098/1176/7468 MHz:
According to monitoring after acceleration, the frequency of the graphics processor in the load reached 1293 MHz, which is also a record among participants in today's material:
As for the temperature of the graphics processor, after overclocking, it increased only by 3 degrees Celsius, and the speed of the cooling system fans remained at the same level.
Inno3d GeForce GTX 660 Ti Herculez2000s
Inno3d GeForce GTX 660 Ti Herculez2000s Sealed into a small vertically oriented box:
Useful information on it is a bit and the whole it seems to us, borrowed from the NVIDIA website. Together with the video card, one cable adapter is supplied to connect the additional power supply, the DVI-TO-D-SUB adapter and the drivers CD:
Country of production - China, warranty - 1 year, retail price - 299 US dollars.
The entire front side of the video card closes the cooling system, which goes a little over the edge of the short circuit board:
The total length of the video card is 203 mm, and the thickness is 42 mm.
The printed circuit board is made on reference design:
Consequently, nothing new or special to say about the flow system of the video card is impossible:
But on the Inno3D installed the most "fresh" graphics processor, released at the junction of June and July of the current year:
The basic frequency of the graphics processor in 3D mode is 915 MHz, in boost mode - 980 MHz, that is, completely standard for GeForce GTX 660 Ti. The same with the memory of the video card, its volume and frequency are identical to the reference and are equal to 2 GB and 6008 MHz, respectively.
Thus, the Inno3D GeForce GTX 660 TI Herculez2000S is the only testing video card, the frequency of which is not higher than the nominal GeForce GTX 660 Ti:
Therefore, interest in this video card can only be the HerculeZ2000S branded cooling system. Compact and lightning it consists of a two-section aluminum radiator on four copper heat pipes with a diameter of 6 mm, two fans in plastic framework, decorative fan linings, as well as a metal plate with thermal stacks on memory chips and power elements:
Note that the radiator's ribs are soldered to heat pipes:
Two 75-mm impeller of the fans are fixed in the plastic framework, the edges of which are engaged in the slits in the side sides of the radiator. The fans are released by Colorful and are based on sliding bearings:
The speed of rotation of the fans is automatically adjusted by the pulse modulation method in the range from 1260 to 3240 rpm. The maximum power consumption of each fan should not exceed 3.4 W.
Let's see how effective Herculez2000S is effective:
Automatic mode Maximum power
The graphics processor warmed up to 71 degrees Celsius in the automatic mode of operation of the fans, when their speed increased to 1680 rpm, and up to 59 degrees Celsius at the maximum 3240 rpm. These are average results for today's testing participants.
The low base frequency of the graphics processor allowed the INNO3D GEFORCE GTX 660 Ti Herculez2000S video card to demonstrate a good overclocking potential. Thus, the core frequency managed to increase by 105 MHz, and video memory - at 980 effective megahertz:
At the same time, the final frequency of the GPU Inno3d was even lower than the basic ASUS and Gigabyte products - only 1020 MHz:
The maximum temperature of the kernel after overclocking the video card was 72 degrees Celsius, and the speed of the fans increased to 1770 rpm:
A good result, given that Inno3D is not so much noise against the background of some other test participants. Go to the next video card review.
KFA2 GeForce GTX 660 TI EX OC 3 GB
The fifth alphabet with the participant of today's testing was the KFA2 GeForce GTX 660 Ti Ex OC video card. The box differs from Inno3d only with dimensions and pattern on the front side, and everything else here is exactly the same:
Along with the video card, two adapter cables are supplied for additional power, adapter DVI-TO-D-Sub, Driver CDs, Installation Instructions and Advertising Booklet:
The video card produced in China, worth 299 US dollars, is provided a two-year warranty.
Against the background of the three previous KFA2 video cards, GeForce GTX 660 Ti Ex OC looks great, more resembling the GeForce GTX 680 than on GTX 660 Ti. Its length is 255 mm:
On the output panel we can only mark the sparse grille:
Mio connectors for SLI-ligaments here are the same as on all other test cards, but with food KFA2, I decided not to notice, and instead of two six-pin connections installed eight and six-contact connections:
At the same time, the requirements for the power supply for a system with one such video card remained the same - 450 watts.
After removing the cooling system, it becomes clear that in front of us - the circuit board from the original KFA2 GeForce GTX 680 Ex OC:
On the nutrition of the graphics processor, five phases are reserved immediately, two more - on video memory:
The Richtek RT8802A controller is responsible for controlling the power of the graphics processor. Obviously, the power circuit in this way should contribute to more successful acceleration and stability at high frequencies. Check.
Externally, the graphical processor of the KFA2 GeForce GTX 660 Ti EX OC video card is different from the above-mentioned marking week of release:
Internally - only the frequency that is 1006 MHz in the base mode, and in the forced - 1085 MHz. This is the average result among other video cards of the material.
KFA2's memory decided not to overclock, leaving regular 6008 MHz, but increased its volume from two to three gigabytes. At the same time, the same HYNIX chips are used here as on all other video cards:
Thus, the KFA2 GeForce GTX 660 TI EX OC specification is as follows:
The original video card cooling system has no own name, but it does not diminish its advantages. This is a massive nickel-plated design with a copper base, four 8 mm thermal tubes and thin aluminum plates:
All places of conjugation places are registered, and even simply visually here it is not difficult to determine that the KFA2 radiator area is the largest among all today's cooling systems:
Two 92-mm impeller are installed in the plastic framework, which are brought to the metal casing. Fan manufacturer is Everflow:
In the fans, a sliding bearing with an increased service life (EBR) is applied. Depending on the temperature of the graphics processor and the load on the video card, the PMW adjustment can change the speed of rotation of the fans in the range from 1100 to 3100 rpm.
KFA2 GeForce GTX 660 TI EX OC has demonstrated the highest cooling efficiency both in the automatic mode of fan speed adjustment and in maximum speed mode:
Automatic mode Maximum power
The graphics processor warmed up only 60 degrees Celsius at the speed of 1620 rpm fans and only up to 49 degrees at the maximum 3090 rpm. This is the best result among all eight video cards.
Unfortunately, such an effective cooling system and enhanced printed circuit board did not contribute to the high acceleration potential of the video card. We were able to cross the graphics processor only at 50 MHz, and the video memory by 1300 MHz:
The final frequencies amounted to 1056/1135/7308 MHz:
According to the monitoring data after the acceleration of the video card, the frequency increased to 1187 MHz, however, the temperature mode of operation KFA2 GeForce GTX 660 TI EX OC, due to the highly efficient cooling system, has not changed:
All the same 60 degrees Celsius with automatic adjustment of the rotational speed of the fans. An interesting product turned out to be at KFA2, now let's get acquainted with the offer of MSI.
MSI N660TI PE 2GD5 / OC TWINFROZR IV 2 GB
MSI N660TI PE 2GD5 / OC TWINFROZR IV - The first video card of the POWER EDITION series, which fell to us for testing. The more interesting will find out what it is different from both reference products and more advanced versions.On the front side of very bright packaging, all basic information about the product is provided, including support for triple stress control and improved PWM control:
On the reverse side of the packaging, detailed video card specifications are given, minimum system requirements and key features on two dozen languages.
Along with the video card, two adapter cables for additional power supply are supplied, one DVI-TO-D-Sub Adapter, a CD with Drivers and Utilities, Installation Instructions, as well as a MSI advertising booklet:
A video card is produced in China and costs 299 US dollars. The warranty period is equal to three years.
Like Asus, MSI video cards are easily recognizable externally, thanks to the branded TWINFROZR cooling system and stylish design:
Note that MSI N660TI PE 2GD5 / OC TWINFROZR IV is the second in length of the video card testing - 257 mm. This must be considered if you plan to assemble the game system in a close building. The thickness of the video card is only 37 mm.
The standard set of outputs in the form of DVI-I and DVI-D (Dual-Link), HDMI and DisplayPort gives GeForce GTX 660 TI with simultaneous support for four monitors, and the MSI video card in this sense is no exception:
Additional power and SLI connectors are identical to the reference, but the printed circuit board at MSI its own development:
In the power part we can see five phases of the function of the graphics processor, two phases on video memory and one on the power chain:
Moreover, in the design of the printed circuit board, only high-quality durable components of the Military Class III class are used, using Hi-C capacitors with a tantalum core, SFC chokes and condensers with Dark Solid Cap solid-state electrolyte. All this, according to MSI, will allow overclockers to squeeze "all juices" from GK104.
The graphics processor is released at the same week as the crystals of ASUS and GIGABYTE video cards:
The nominal frequency for the 3D-mode is 1020/1098 MHz, but according to the monitoring data increased to 1176 MHz. That is pretty good factory overclocking. But the amount of memory (2 GB) and its frequency (6008 MHz) are standard, as well as the HYNIX microcircuits used:
Let's look at the MSI N660TI PE 2GD5 / OC specification and then turn to the cooling system TWINFROZR IV:
The original MSI cooler is already well familiar to our regular readers, since his company establishes on many of its other models of video cards that we tested earlier. In its basis, an aluminum radiator on four copper nickel-plated heat pipes with a diameter of 8 mm, leaving copper base:
It features two fans closed on top of a metal casing. To cool the memory chips and power keys, a metal plate with thermal layers is used. Skink was used in the radiator.
The fans with a diameter of 80 mm are released by POWER Logic (model - PLD08010B12HH) and are based on a double rolling bearing:
This is not the best choice in terms of noise level, but ideal in terms of durability. Nevertheless, MSI declares about 17.1 dB gains noise level and about a 14-degree advantage over temperature in comparison with the reference cooler. With the temperature TWINFROZR IV really copes well:
Automatic mode Maximum power
70 degrees Celsius with automatic adjustment (1620 rpm) and only 55 degrees Celsius on the kernel at the maximum power of the fans (4170 rpm). What is there and the rest of the coolers with the level of noise, we will learn a little later.
When checking the overclocker potential, the video card found out that the frequency of the graphics processor can be listed without loss in stability and image quality, and the video memory frequency is 1160 MHz:
As a result, the acceleration of the GPU MSI N660TI PE 2GD5 / OC took second place of eight testing video cards, and the final frequencies amounted to 1110/1188/7168 MHz:
After overclocking the temperature of the nucleus in the load increased by 3 degrees Celsius at the final 73 degrees and 1740 rpm of two twinfrozr iv fans:
The peak of the kernel during tests according to the monitoring data reached 1266 MHz. It cannot be said that the MSI product calls "a storm of positive emotions", but in general it is quite a good and attractive for the buyer of the video card. However, do not rush to run to the store, we have the next participant and comparative charts in the queue.
Palit GeForce GTX 660 Ti Jetstream 2 GB (NE5X66TH1049-1043J)
Palit video cards are the regulars of our tests, and today we will get acquainted with GeForce GTX 660 Ti Jetstream. If the choice of the best video card was dependent on the size of its box, then Palit would have taken this "nomination" - its box is the largest among all testing participants:
We see the design of the back of the box today for the third time - not all designers bother themselves fantasy. But the Palit the top cover of the box is open, opening out the potential buyer and the video card itself and comprehensive information about it:
Complete set without findings: two adapters, power cable and drivers drive:
The homeland product is "subwayen", the cost is 299 US dollars and one year warranty.
The jetstream-design of Palit products are also easily recognizable. The plastic casing with two transparent fans and the hieroglyph between them is remembered at a glance:
The length of the video card is small - only 245 mm, but the thickness is more than the remaining seven video cards and is 49 mm. Thus, use this model in SLI mode when the PCI-Express location is located on the Motherboard "through one".
Two six-contact connections for additional nutrition, two MIO connectors and outputs here are standard:
We see the video card with a printed circuit board today in the fourth time - this is a copy of reference design:
At the same time, several other batteries are installed on Palit than on EVGA or INNO3D, although the phase configuration remained the same: "4 + 2 + 1":
The graphics processor A2 revision, as well as all the other GPUs, released in Taiwan on the 28-nm technical process and dated 13th week 2012 (March-April):
Its base frequency is 1006 MHz, forced - 1085 MHz, which according to monitoring data and at high load reaches 1150 MHz.
Unlike all the video cards discussed above, their two gigabytes of memory in Palit decided to disperse. True, it was embarrassed with overclocking and added to the rated frequency of 6008 MHz, only 100 MHz at the final 6108 MHz. To use some other chips, a clear case, it did not need - here are all the same chips HYNIX H5GQ2H24AFR R0C:
Specifications Palit GeForce GTX 660 Ti Jetstream are shown in the GPU-Z screenshot:
The video card is set exactly the same cooling system as on Palit GeForce GTX 670 JetStream With an aluminum radiator on three copper thermal tubes with a diameter of 6 mm and a plastic casing with two fans:
On the power elements a high aluminum radiator with thermal block laying is installed.
Fans, like MSI, released Power Logs and are labeled PLA09215S12H:
Thanks to the support of PWM control, they can rotate at a speed of 900 to 2900 rpm.
The temperature mode of the video card is not very different from other test participants: 71 degrees Celsius in automatic mode of operation of fans and only 55 degrees Celsius at maximum speed:
Automatic mode Maximum power
Despite the use of the reference printed circuit board, the lack of newcomer technologies and not a record cooling system, our instance of the Palit GeForce GTX 660 Ti Jetstream accepted the kernel at 135 MHz (the best result), and on video memory - by 1200 MHz, which is also quite good:
The frequencies of the video card after overclocking amounted to 1141/1220/7308 MHz:
Moreover, in the 3D load, the peak frequency of the graphics processor was held at a level of 1285 MHz, which is only below Gigabyte:
But the temperature after overclocking the video card, in our opinion, is still high - 77 degrees Celsius at 1470 rpm.
Go to the last test participant - the product of ZOTAC product.
Zotac GeForce GTX 660 Ti Amp! EDITION 2 GB (ZT-60804-10P)
We have already studied ZOTAC GeForce GTX 660 Ti in the basic article about GTX 660 TiNow it's time to get acquainted with an accelerated version - Zotac GeForce GTX 660 Ti Amp! Edition..The video card is sealed in the mid-sized cardboard box, on the front side of which the model, memory, the DIRECTX 11 support and other technologies, the extended warranty and the DUAL SILENCER cooling system are indicated:
On the back of the box schematically drawn the video card itself and individual icons indicate that its 10 degree Celsius cooling system is more efficient and for 10 dB quische with the GeForce GTX 660 Ti reference cooler, plus what amp! EDITION is 10% faster. The following are key features of the video card, various NVIDIA technologies and minimal system requirements are still listed.
The video card package includes two adapter cables to connect the power supply, DVI-TO-D-SUB adapter, a CD with drivers, utilities and software, brief and complete installation instructions, as well as a coupon for downloading the game Trackmania 2:
The video card is produced in China and is recommended for sale for 299 US dollars, that is, exactly for the same money as the reference GeForce GTX 660 Ti 2 GB. ZOTAC provides its video card with a so-called extended warranty for a period of 3 years.
Zotac GeForce GTX 660 Ti Amp! EDITION The most compact video card testing is its size constitute only 191x100x37 mm:
We have the fifth and last reference design of the printed circuit board:
Here, as in other four cases, "references", four phases of the graphics processor and two phases of the video memory:
The graphics processor GK104 A2 revision is released again in Taiwan, and again at the 18th week of 2012:
The basic frequency of the ZOTAC graphics processor in 3D mode is 1033 MHz (1111 MHz - in forced mode), which is immediately 118 MHz above the base frequency of the reference GeForce GTX 660 Ti. According to monitoring data, the GPU frequency increased to 1215 MHz. We add that when switching to 2D mode, the frequency is reduced to 324 MHz at a voltage of 0.987 V.
HYNIX memory microcircuits with exactly the same label, as with all other testing video cards:
However, unlike other participants, ZOTAC GeForce GTX 660 Ti Amp! EDITION The effective memory frequency is 6608 MHz. This should give odds to the ZOTAC product in the resource-intensive modes using smoothing. Check tests.
Let's look at the characteristics of this video card:
On Zotac GeForce GTX 660 Ti Amp! Edition, as well as on the usual version of this video card, the original DUAL SILENCER cooling system is installed with three copper thermal tubes with a diameter of 6 mm:
On a compact aluminum radiator with thin ribs, two 70mm fans are installed, closed with metal casing:
Fans are released under the Apistek label and are labeled GA81S2U. The speed of their rotation is controlled automatically by pulse modulation (PWM) in the range from 1100 to 3500 rpm.
The maximum power consumption of each such fan should not exceed 4.6 W.
Check the effectiveness of Dual Silencer on an overclocked ZOTAC GeForce GTX 660 TI AMP factory! Edition:
Automatic mode Maximum power
In general, it is not bad, although before the records of today's test are distant: 71 degrees Celsius in automatic mode and 65 degrees Celsius at maximum fan power.
As with all other testing participants, the overclocking potential of the ZOTAC video card was studied with the maximum Power Limit value, which is 123% for this video card. The GPU frequency of the video card managed to raise by 65 MHz, and the video memory only on 260 effective megahertz, which, alas, is the worst test results:
The final frequencies of the video card amounted to 1098/1176/6868 MHz:
The maximum frequency of the graphics processor in 3D mode after acceleration according to the monitoring data was 1280 MHz:
The GPU temperature increased to 72 degrees Celsius at a fan speed of 2490 rpm. It's time to tell about the noise level of all video cards of testing, as well as look at the summary temperature charts and the frequency table.
Noise level, summary temperature charts and frequency table
Measuring the noise level of the cooling systems of video cards was carried out using the CENTER-321 electronic noiseomer after an hour in a fully closed room with an area of \u200b\u200babout 20 m² with double-glazed windows. The noise level was measured outside the system unit housing when the source of noise in the room was only the cooling system and its fans. The sound meter, fixed on the tripod, has always been located strictly at one point at a distance of exactly 150 mm from the fan rotor / cooler turbine. The motherboard in which the video card was inserted with the cooling system installed on it, was placed at the corner of the table on the polyurethane foam substrate. The lower limit of the noiseomer measurements is 29.8 dBa, and the subjectively comfortable (not to be confused with low) noise level during measurements from such a distance is near the 36 dBA mark. The speed of rotation of the fans changed throughout the range of their operation using a special accurate controller by changing the supply voltage in increments of 0.5 V.Let's see what happened on schedule and table:
Obviously, the most quiet is the Cooling system DirectCu II ASUS video card, and this is confirmed by a subjective assessment of the noise level. In second place - the cooler Zotac Dual Silence, but the general group of the rest of the video cards he won quite a bit. Also note for a very high noise level of the cooling system Palit Jetstream and the reference EVGA video card cooler. The remaining video cards are approximately the same by noise level.
However, you should not forget that with automatic adjustment of the speed of rotation of the coolers, they achieved different speeds, so it would be useful to note on the schedule of their border of the work, which we always and make in articles about video cards. But since today we immediately have eight video cards, then an unreadable meal would be on the chart. Therefore, we did somewhat differently, making the noise level in the automatic mode of operation of the coolers and at their maximum speed to a separate diagram and adding these results with data on the maximum graphics processor temperature. Video cards in the diagram in each mode testing are sorted in ascending order of noise level. We look:
In automatic operation, the ASUS GeForce GTX 660Ti DirectCu II Top video card operates in automatic operation, which is not surprising at its maximum 1440 rpm. At the same time, the ASUS video card ranked third at the maximum graphics processor temperature. Impressive result! Next, with a decent difference in noise, a dense group of video cards INNO3D, MSI and KFA2 is underway, among which the latest video card is allocated with its cooling efficiency. Its cooler is generally the best among all eight video cards of the article. Following with a small lag behind, Gigabyte and EVGA video cards are followed, and the reference cooler is quite naturally the outsider in efficiency. Well, more than all the Palit and ZOTAC products are no longer the automatic mode.
At the maximum fan speed, the picture has changed. In terms of noise, the leaders came out by the Gigabyte video card, and ASUS moved to second place, while at the same time bypassing Gigabyte by 6 degrees Celsius at peak graphics processor temperature. ZOTAC from an outsider turns into one of the leaders, although the temperature of this video card is the highest at the maximum speed of rotation of the fans. Standing from ZOTAC Only 0.1 dBA, the Cooling Cooling System INNO3D cools the graphics processor for 6 degrees Celsius is better. True, you should not forget about the difference in the GPU frequencies. The KFA2 product is again located "in the middle of the peloton", and again leads the temperature. The remaining tripler from EVGA, MSI and Palit demonstrates the practical equal noise level results and temperatures.
Next, we brought into a separate table all the frequencies of video cards in the nominal mode of their work and after overclocking. The best results are marked in red, the worst - blue:
Interestingly, despite the highest factory frequencies, the ASUS video card did not demonstrate the maximum frequency in the load (according to the monitoring data). The leader in this indicator was the Gigabyte video card. The Palit product demonstrated the highest potential of the kernel overclocking, but in the load, the frequency of Gigabyte again turned out to be slightly higher. Note that the Power Limit at Gigabyte is not the highest, however, it is from this card that the GPU frequency in the load rises above the rest. In addition, Gigabyte has a better memory of everyone. The worst core acceleration turned out to be an Inno3D video card, and on the acceleration of video memory - ZOTAC.
Now the temperature of the graphic processors of video cards in acceleration and the noise level of their cooling systems with automatic adjustment mode to one diagram, sorting the video card from top to bottom in the order of increasing noise levels:
As before, the leader in the noise level after overclocking video cards remained the ASUS product, and it also belongs to the second place at the temperature of the graphics processor. But the first with a huge 10-degree advantage is the KFA2 video card. This video card has a really most effective cooler, and thanks to him KFA2 was able to rise to second place in terms of noise. Following a dense group from Inno3d, MSI and Gigabyte products. They demonstrate not only almost the same noise level, but also the temperature of graphics processors. True, you should not forget about the frequencies that MSI and Gigabyte are higher than that of INNO3D. The remaining Trinity from the ZOTAC video cards, Palit and EVGA is noise above 50 dBA, but if ZOTAC holds the temperature of the graphics processor at the level of other higher testing participants, then Palit and EVGA are not possible, they lose 5..6 degrees Celsius. Go ahead.
Energy consumption
Measuring the power consumption of a system with various video cards was carried out using the Zalman ZM-MFC3 multifunction panel, which shows the consumption of the system "from the outlet" as a whole (excluding the monitor). Measurement was carried out in 2D mode, with normal operation in Microsoft Word or Internet-"Surfing", as well as in 3D-mode, the load in which was created using a three-time test from the Metro 2033: The Last Refugee game in the resolution of 2560x1440 at maximum settings Graphics quality but without using smoothing.Let's see what we did:
The difference in power consumption of systems with eight original GeForce GTX 660 Ti is not significant. From the general range, the instance of ZOTAC is embossed, apparently due to the increased frequency of the video memory. In all other cases, the difference is laid in 10-12 watts, which, with the overall power consumption of the system, about 400 watts does not play any role. We dare to assume that all the statements of manufacturers about the economy of their video cards against the background of competitors are no more than marketing tricks. As for the arched GeForce GTX 660 TI performed by Gigabyte, the power consumption of the system with it 14 watts is higher than in the nominal mode of operation, and almost reaches the level of Gigabyte GeForce GTX 670. Maximum consumption demonstrates the system with Sapphire Radeon HD 7950, stacking anyway 450 watts.
Test configuration, toolkit and testing technique
Testing video cards was performed on the following configuration system:
System board: Intel Siler DX79SI (Intel X79 Express, LGA 2011, BIOS 0537 dated 07/23/2012);

Monitor: 27 "SAMSUNG S27A850D (DVI-I, 2560x1440, 60 Hz).
In addition to video cards from a review in testing, we have added two more video cards: Gigabyte GeForce GTX 670 Ultra Durable 2 GB and Sapphire Radeon HD 7950 Dual-x 3 GB with the latest version of BIOS:
As we see, the frequencies of these video cards are raised relative to the nominal, but we did not reduce them to the reference layer, since almost all the GeForce GTX 660 Ti are tested today have increased frequencies.
To reduce the dependence of the video card performance from the platform speed, 32-nm a six-core processor with a multiplier 37, a support frequency of 125 MHz and the activated "Load-Line Calibration" function was overclocked to 4.625 GHz with raising voltage in the motherboard BIOS to 1.49 V:
Hyper-Threading technology is activated. At the same time, 16 GB of RAM was functioned at a frequency of 2 GHz with timings of 9-11-10-28 at a voltage of 1.65 V.
Testing started on September 14, 2012 was conducted under the Microsoft Windows 7 Ultimate X64 SP1 operating system with all critical updates to the specified date and with the installation of the following drivers:
chipset Motherboard Intel Chipset Drivers - 9.3.0.1021 WHQL dated 07/27/2012;
libraries DirectX End-User Runtimes, release date - November 30, 2010;
video Card Drivers on AMD Graphic Processors - Catalyst 12.8 (8.982.0.0) of 08/15/2012 + Catalyst Application Profiles 12.8 (CAP2);
video card drivers on NVIDIA graphics processors - GeForce 306.23 Beta dated 08/27/2012.
Since we have 10 video cards in tests today, then their performance we have checked only in one resolution of 1920x1080 pixels. However, two chart quality modes were still used for tests: "Quality + AF16X" - the quality of the textures in the default drivers with the inclusion of anisotropic filtering level 16x, and "Quality + AF16X + MSAA 4x (8x)" with inclusion Anisotropic filtering of the level 16x and full-screen smoothing of degrees 4X or 8X, in cases where the average number of frames per second remained high enough for a comfortable game. The inclusion of anisotropic filtering and full-screen smoothing was performed directly in the game settings. If these settings in the games were absent, then the parameters changed in the Catalyst and GeForce drivers control panels. It also disabled vertical synchronization. No more changes in the driver settings were made.
The list of test applications was reduced to one semi-synthetic package and 7 the most recent and resource-intensive games updated to the latest versions (at the start date of tests). That's what it looks like:
3dMark 2011. (DirectX 11) - version 1.0.3.0, Profiles of "Performance" and "Extreme" settings;
Metro 2033: The Last Refuge (DirectX 10/11) - Version 1.2, used official test, Quality settings "Very High", Tessellation, DOF included, AAA smoothing was used, a double serial pass "Frontline" scene;
Total War: Shogun 2 (DirectX 11) - version 2.0, built-in test (battle at sekigahara) on the maximum graphics quality settings and use in one of the MSAA 4x modes;
Crysis 2. (DirectX 11) - version 1.9, used Adrenaline Crysis 2 Benchmark Tool V1.0.1.14 Beta, profile of the quality settings "Ultra High" graphics, high-resolution textures are activated, two-time DEMO-record cycle on the Times Square scene;
Battlefield 3. (DirectX 11) - version 1.4, all graphics quality settings on "Ultra", double sequential passage of the scene from the beginning of the "Hunting" mission lasting 110 seconds;
Nexuiz (DirectX 11) - version 1.0, all graphics quality settings on Ultra, double run-in test game on the "High" and Ultra settings profiles;
Sniper Elite V2 Benchmark (DirectX 11) - version 1.05, used ADRENALINE SNIPER ELITE V2 BENCHMARK TOOL V1.0.0.2 Beta Maximum graphics quality settings ("Ultra"), Advanced Shadows: High, Ambient Occlusion: ON, STEREO 3D: OFF, double dough runoff;
Sleeping Dogs. (DirectX 11) - version 1.0, built-in test, maximum graphic quality settings for all items, Hi-Res Textures Pack is installed, FPS Limiter and V-Sync are disabled, double test test with a total smoothing at the "Normal" level and at the level " Extreme. "
We add that if the game implements the possibility of fixing the minimum number of frames per second, it also reflected in the diagrams. Each test was performed twice, the final result was made the best of the two values \u200b\u200bobtained, but only if the difference between them did not exceed 1%. If the deviations of the tests exceeded 1%, then testing was repeated at least at least once to get a reliable result.
Performance test results and analysis
On GeForce GTX 660 Ti video cards are located in alphabetical order, as in the review, and "frame" them GeForce GTX 670 and Radeon HD 7950. Gigabyte GEFORCE GTX GTX 670 Ultra Durable 2 GB is marked with green - Sapphire Radeon HD 7950 Dual -X 3 GB, and dark-turquoise - all GeForce GTX 660 Ti with a separate allocation of results overclocked Gigabyte GeForce GTX 660 Ti. The amount of memory is specified only in the KFA2 product, according to quite, in our opinion, of understandable reasons.3dMark 2011.
Despite the proximity of the frequencies of the majority of GeForce GTX 660 Ti, in the "Performance" settings mode, we can observe a noticeable variation of the results. Moreover, it is also leading not the products of ASUS or ZOTAC, which have the highest core and memory frequencies, respectively, and Gigabyte. Probably, it is the maximum peak frequency of a graphics processor, which at the Gigabyte GeForce GTX 660 Ti Ultra Durable is the highest, allowed this video card to escape into leaders. The last place among GeForce GTX 660 Ti quite naturally occupied the InnO3d product, whose frequencies are equal to the reference. In the "Extreme" settings mode, the difference between video cards is leveled, but Gigabyte and Zotac are still slightly faster than everyone else.
Metro 2033: The Last Refuge
In Metro 2033: The Last Refuge the difference in the performance of all eight GeForce GTX 660 Ti is either absent or is 1-2 frames per second. Mathematically, the leadership belongs to ZOTAC, yet the factory overclocking the video memory of this video card was not in vain. Note that Radeon HD 7950 in this game is ahead of all GeForce GTX 660 Ti and even a slightly overclocked GeForce GTX 670. Sense from the additional gigabyte video memory of the KFA2 product.
Total War: Shogun 2
Minimal difference between GeForce GTX 660 Ti and in the game Total War: Shogun 2. Only in the mode without using smoothing, we can observe a slight spread of the results. The slowest reappears inno3d, and the fastest - Gigabyte and Zotac. Related GeForce GTX 660 Ti is not inferior to Gigabyte GeForce GTX 670 Ultra Durable, and 3 GB of video memory on KFA2 again do not bring effect.
Crysis 2.
The same picture is repeated in the game CRYSIS 2:
Battlefield 3.
A slightly larger scatter of the results of GeForce GTX 660 Ti We can observe in the game Battlefield 3, but the leaders and outsider remained the same. Three gigabytes of memory on KFA2 in these test modes do not bring additional productivity growth in comparison with conventional two-scale GeForce GTX 660 Ti.
Nexuiz
In the test game Nexuiz, only ZOTAC product was able to stand out on a general background of the results of GeForce GTX 660 Ti, and Gigabyte rates closer to the bulk of these video cards. It is impossible not to note the overwhelming superiority of the Radeon HD 7950 in this game created with the support of AMD, by the way.
Sniper Elite V2 Benchmark
In the Sniper Elite V2, the difference between the original GeForce GTX 660 Ti can only be seen in the mode without using smoothing, where ZOTAC and Gigabyte is once a little faster than the remaining video cards. As for the mode with the use of supersembling, the difference in performance does not exceed 1-2 frames per second. At the same time, all the video cards are tested today on NVIDIA graphics processors much slower than Sapphire Radeon HD 7950.
Sleeping Dogs.
Not knocked out of the general range and test results in the game Sleeping Dogs.
We apply the outcome to the charts, and go to the conclusion.
Conclusion
Despite the above-dimensional frequencies of eight GeForce GTX 660 Ti video cards, considered and tested in today's article, the performance of the slowest of them is the right of the right, the right is different on average by no more than 6-8%. Such a difference is not all players will be able to feel. However, given that the cost of video cards will be varied by no more than 10 US dollars, most of us will choose the fastest of them, which is pleasant at least from a psychological point of view. There are no tangible advantages and the video card with three gigabytes of memory, against the usual two gigabytes, as shown the tests of the KFA2 product. At least, this is true for the resolution of 1920x1080 pixels, including modes using smoothing. Throughout this, on the "advancement" of the difficult choice of GeForce GTX 660 Ti, such characteristics as the noise level and cooling efficiency are crowded with overclocking potential. And if we cannot estimate the latter objectively, having only one instance of each video card on tests, then the estimate of the first two characteristics today was made. It's time to distribute to all the sisters on small "earrings."ASUS GeForce GTX 660Ti DirectCu II Top is the best choice of all the tested GeForce GTX 660 Ti, in our opinion. And the case is not at all in the highest frequency of the graphics processor, but in a very quiet and fairly efficient cooling system capable of satisfying both the most demanding level of the noise of Estet and overclockers. The latter will also have a reinforced printed circuit board with a high-quality element database and a three-year warranty. The poor equipment of the video card does not correspond to its status, but this moment is still not critical when choosing.
EVGA GeForce GTX 660 Ti SuperClocked is a reference with a slightly increased frequency of the graphics processor. As if we did not respect the company EVGA, but today's round she lost, taking only the last eighth place. Noisy and relatively ineffective cooler, simple reference PCB and unbearable indicators when accelerating and in performance tests. All this does not allow us to recommend this video card to purchase. Isn't EVGA already removed this model from production, replacing for more interesting modification of FTW?
Gigabyte GeForce GTX 660 Ti Ultra Durable - did not hit the face of Gigabyte in today's review and testing. Like all the other six dough participants, it loses in terms of noise and efficiency asus product, but lags behind quite a bit. In addition, in the tests of Gigabyte, all other video cards are consistent with the exception of ZOTAC. Perhaps we would give the Gigabyte third place in today's material.
Inno3D GeForce GTX 660 Ti Herculez2000s is another model with a reference printed circuit board. However, unlike EVGA, Inno3D engineers equipped their video card with the original cooling system, and, judging by the results demonstrated by it, it turned out quite well. But the frequencies they have forgotten the factory, but it would be quite high, because inno3d GeForce GTX 660 Ti Herculez2000s turned out to be the only video card in an article with rated frequencies.
KFA2 GeForce GTX 660 Ti Ex OC 3 GB is primarily a video card with a stunningly efficient cooler. Even a reinforced printed circuit board, which is a copy of the flagship GTX 680 EX OC, is moving into the background when the original KFA2 cooler will "brings" all other test participants 10 degrees Celsius at the maximum temperature of the graphics processor. In addition, the increased frequency of the GPU and the moderate noise level, the final second place on the combination of noise and temperatures after acceleration of video cards allow us to give the second after the ASUS space of the KFA2 video card.
MSI N660TI PE 2GD5 / OC TWINFROZR IV - nothing bad we cannot say about the MSI video card. It is a very high-quality product with an expensive and reliable element base, an effective cooler, an increased frequency of graphics processor and in addition stylishly looking. The bonus in the form of a system for removing dust from the cooler and is completely unique. MSI N660TI PE 2GD5 / OC TWINFROZR IV is a bit more tricking, a little quickly and a droplet is more effective, it would be quite able to get around Gigabyte or even ASUS. We recommend buying, but still only in the absence of test leaders.
Palit GeForce GTX 660 Ti Jetstream - and newly reference circuit board, original cooler and increased graphics processor frequencies and even memory. However, it is the high level of noise of the cooling system JetStream, it does not allow us to recommend this model to the acquisition. The company's engineers should still work on a plastic casing in which fans are fixed to reduce the noise-produced and make a video card more attractive from this point of view. At the same time, we recall that it was Palit today who today demonstrated the highest overclocking potential of the GPU.
Zotac GeForce GTX 660 Ti Amp! EDITION - The smallest video card material turned out to be the fastest amount of all tests. Due to the significantly increased memory frequency and the core frequency at the level of video cards of other manufacturers, ZOTAC was able to beat all the other GeForce GTX 660 Ti. But in terms of cooling efficiency and noise level, ZOTAC leaders have not yet reached. Perhaps, just released version of AMP! EXTREME EDITION will be able to achieve this? We'll see. And we have everything today.
The price is less - the product is more valuable, it is true that this rule is not infinity, because the video cards, for example, at a cost of about $ 100 can demonstrate all the possibilities of three-dimensional graphics already in a limited version and at low permissions. Therefore, somehow it happened in the Russian market, the costs of 150 to 200 dollars use the greatest demand. This review is devoted to a more expensive product that recently released GeForce GTX 660 Ti, but it is distinguished by the fact that it has a much more attractive price, rather than top GTX 680/670, and at the same time it is not very weaker than the GTX 670. In general, Usefulness in 660 Ti is clearly higher than 670/680.
So, today we will study the serial product produced by Gigabyte, based on the above GPU. About the manufacturer, I suppose, do not need to tell - this is the most famous and oldest world IT brand. All Gigabyte maps that we studied in recent years have possessed both great CO and a good price-quality ratio.

All our explanations are directed, as a rule, on newcomers or inexperienced users who want, however, produce upgrade their computer or simply collect new. Those who do not understand what the core is why there are so many processors that such flows and so on makes sense to familiarize themselves with our brief directories on the families of modern video cards and processors based on which they are issued. It should be noted the frequency of work, support for modern technologies (shaders), as well as conveyor architecture. And now let's look at the tests. We present the GTX 660 Ti tests in two modes: at nominal frequencies and at elevated to 1100 MHz on the kernel. The Gigabyte product has intermediate frequencies, so you can easily estimate its location.
conclusionsLet's start with the analysis Site accelerators ratingwhich demonstrates us the functionality of video cards relative to each other and normalized by the lowest accelerator - GeForce GT 630 (that is, the combination of speed and functions GT 630 are taken for 100%). We give a sample from this rating. Rating 3D accelerators Website
Actually, as we see, the overclocked version of the GTX 660 Ti leads in the ranking inside its group. Yes, no less overclocked version of the competitor HD 7870 clicks on the heels, so we can assume that our case with the Gigabyte product can also give up the championship, but no more. Look at that even working at regular GTX 660 Ti frequencies bypass not only the opponent in the face of HD 7870, but even more expensive HD 7950! Usefulness rating (capabilities / price)
As expected, and in this case we see that GTX 660 Ti, working at elevated frequencies, got into leaders. Yes, a competitor is pressed again in the face of HD 7870, but still GTX 660 Ti looks preferable. Now on the map itself. Gigabyte GeForce GTX 660 TI OC 2048 MB 256-bit GDDR5 PCI-E (GV-N660TOC-2GD) - An excellent version of the new product of the average price range (which can be so to speak, to the top level). The accelerator has excellent CO, relatively small sizes and has all the output needs for today. Well, once again remind you that inside your group GTX 660 Ti looks an explicit leader. The final decision traditionally remains for our readers. We only give information about the products considered, but do not make direct instructions on the selection of a particular product. |

The previous review described about three new GeForce GTX 660 Ti video cards produced by MSI, EVGA and ASUS. However, along with video cards from these manufacturers, graphic cards from Gigabyte are very popular. This company presented its own version of the GTX 660 Ti, which will be discussed.
In a review, which prepared the expert TechSpot portal Steven Walton, the specifications and performance of the Gigabyte GV-N66TOC-2GD video card with factory overclocking are considered in detail. It was this modification that would be more correct to compare with the overclocked video cards from ASUS, EVGA and MSI.
The main competitors of the GeForce GTX 660 Ti are video cards based on Radeon HD 7870 and Radeon HD 7950. However, it is already known from the results of the GXT 660 TI testing, the Radeon HD 7870 is almost always inferior to GeForce GTX 660 Ti in performance. Even the "basic" Radeon HD 7950 often shows the worst results compared to the video cards from NVIDIA, and only the Radeon HD 7950 Boost with the video card activated in the BIOS highly significant acceleration of the graphics processor with varying success is opposed to GTX 660 Ti.
For details on comparing GeForce GTX 660 Ti with its main rivals Radeon HD 7870 and Radeon HD 7950, as well as on features and characteristics of the GK104 chip itself, on which GTX 660 Ti is based, you can read. In the current review, the video card from Gigabyte focus on the video card.
Gigabyte Specifications "S GTX 660 Ti
nVIDIA did not create a full-fledged reference (reference) video card with GPU GTX 660 Ti, in such a way to partners independently choose the design for their products. Therefore, video cards from different manufacturers differ markedly from the design of printed circuit boards: some companies decided to use as the basis of the PCB from GeForce GTX 680, while others rely on the design of the printed circuit board, intended for GeForce GTX 670.

The GV-N66TOC-2GD model from Gigabyte turned out to be quite compact: its boot length does not exceed 21.5 cm, but the radiator increases the dimensions of the video card - up to 25 cm, which roughly corresponds to the length of the Radeon HD 7870, but at the same time significantly "does not reach" to Length of top video cards like Radeon HD 7970. Gigabyte GeForce GTX 660 Ti can be easily accommodated in most ATX-enclosures.
The GTX 660 TI graphics chip contains 1344 CUDA kernels (shader blocks) and 7 SMX blocks, which is 192 CUDA kernels and 1 SMX block smaller in comparison with GTX 680, but equal to similar indicators for GTX 670 (however, the number of rasterization blocks It was reduced from 32 to 24 compared with GTX 670).
As for graphics, Gigabyte GeForce GTX 660 Ti uses 2 GB of the GDDR5 standard with a nominal frequency of 1502 MHz (effective memory frequency is 6008 MHz) and a bandwidth of 144.2GB / s. However, the size of the memory bus is reduced from 256 bit to 192 Bit, which leads to a slight decrease in the performance of GTX 660 Ti, if compared with GTX 670.

However, the most important feature of the video card from Gigabyte should be considered the working frequencies of its graphics processor: the manufacturer dispersed GPU by more than 10 percent. If the standard GTX 660 TI frequencies are 915 MHz in normal mode and 980 MHz in Boost-mode (performance mode), then in the Gigabyte video card specifications, we already see 1032 MHz and 1111 MHz for the usual and boost mode, respectively.
Noteworthy Gigabyte GeForce GTX 660 Ti and its unique active cooling system: The GV-N66TOC-2GD model is equipped with a windforce 2x branded cooling system, including two 75 million fans. The fans are mounted on a massive radiator consisting of three main segments, combined with thermal tubes with a diameter of 8 mm. One of the radiator blocks is responsible for efficient graphics cooling. The TRIANGLE COOL technology, which determines the configuration of the cooling system elements, is based on the use of triangular modules, which, due to its form, contribute to the best heat removal from the radiator. Gigabyte claims that with the help of Triangle Cool, it is possible to reduce the working temperature of the video card by 10 percent compared to conventional radiators.

To power the video card at its board there are two 6-pin PCIe connector - as much as Radeon HD 7870 and GeForce GTX 670. The recommended power supply power (PSU), if we proceed from the clarification of NVIDIA, should be at least 550W (although The minimum value is 450-500W, in real conditions, the use of such a "weak" power supply will lead to unstable operation of the system with frequent reboots).
Gigabyte GeForce GTX 660 Ti supports 3-way SLI technology: there are two SLI connector on the board. Two DVI connectors are located on the back panel of the video card (one dual-channel DVI-I and one DVI-D), HDMI 1.4A port, and DisplayPort 1.2.
Test stand and list of tested video cards
The system configuration used to test video cards includes: Intel Core I7-3960X Extreme Edition processor, operating at a frequency of 3.30GHz, 8 GB RAM G.skill DDR3-1600 with CAS 8-8-8-20 timings, motherboard ASRock X79 EXTREME11 based on Intel X79 chipset, 512GB CRUCIAL M4 solid-state drive and OCZ ZX Series Power Supply 1250W.

Testing was conducted in the Windows 7 x64 operating system. For NVIDIA video card tests installed NVIDIA ForceWare drivers 301.42 and a newer version of NVIDIA FORCEWARE 305.37, optimized to work with GTX 660 Ti. Radeon HD video card tests were performed on a system with AMD Catalyst 12.7 installed drivers.
For synthetic video card performance tests, 3DMark 11 Pro Edition has been selected. Testing was carried out in Performance modes ("Performance") and Extreme. The standard version of the GTX 660 Ti scored 2755 points, and the video card from Gigabyte turned out to be 5 percent faster, showing the result equal to 2903 points. It is very close to the results of both the GTX 670 and one of the top video cards from AMD - 7970 GHz Edition. And your direct competitor - Radeon HD 7870 - Gigabyte GeForce GTX 660 Ti overtook by 33%.

Energy consumption, temperature modes and noise level
Gigabyte GeForce GTX 660 Ti consumes almost as much energy as its "older" sister GTX 670. This is explained, apparently, there is no significant difference in the plan of the component base between two video cards. Despite the fact that the GK104 chip version for GTX 660 Ti, several "simplified", the factory overclocking of the graphics processor in the tested model of the Gigabyte video card led to an increase in energy consumption. In addition, GTX 660 Ti consumes 11 percent more energy compared to HD 7870.

Under the load, the GIGABYTE GPU temperature reached 77 degrees Celsius (maximum value for all time testing), which is slightly higher than that of the Radeon HD 7870 ICEQ production of HIS, but is within the limits of allowable. As for the average temperature in games, it, as a rule, does not exceed 65-70 degrees. Approximately the same values \u200b\u200bwere observed in MSI and ASUS video cards.
.png)
The noise level under load can be called moderate: 43 dB (a) on the close distance. Recall, MSI is equal to 40 dB (a), and ASUS is about 37 dB (a). However, it is worth noting that the maximum level of fan revolutions near the Gigabyte video card reaches 52%, while MSI does not exceed 41%. However, using a special software can be manually reduced the maximum frequency of fan speed.

Conclusion
The Gigabyte GV-N66TOC-2GD video card showed itself from the best side in most of the tests carried out: it turned out to be faster than the price of the Radeon HD 7870 video card and confidently competes with a more expensive Radeon HD 7950. However, somewhat confuses relatively high power consumption - at GXT 670 So do not forget to purchase a powerful power supply unit (we recommend the power level from 550 W). The WindForce 2X cooling system is effectively coping with its tasks, supporting the acceptable temperature values \u200b\u200bunder load. If you have a "quiet" system, it may be necessary to reduce the frequency of fan speeds up to 45%, so that the video card does not stand out on the overall background with the noise produced.
