Gigabyte GeForce GTX980 G1 Gaming Video Card Review: Alone and SLI. Gigabyte GeForce GTX980 G1 Gaming Video Card Review: Alone and SLI ⇡ Cooling Systems - Efficiency and Noise Level

Which demonstrated outstanding overclocking indicators against the background of comrades. It has staged the older model. Let's see if the Gigabyte GV-N980G1 Gaming-4GD will be surprised after review top versions GeForce GTX. 980 from MSI and ASUS and did not exceed the reference sample by final frequencies.

The video card comes in a large box of simple design.


Supply set:

  • two adapters from two Molex on PCI-E 8-PIN;
  • disk with software;
  • instruction.
Externally, GV-N980G1 Gaming-4GD does not differ from the younger version. A similar two-fledged cooling system with three fans, which highlight a special catchy design with grooves on the surface.


The side face of the cooler is crowned with a large inscription windforce with backlight. Started in the presence of two power connectors for eight contacts.


The total length of the adapter reaches 29.5 centimeters, but the board itself is shorter.


The back side is closed with a metal plate with slots.


A set of interface connectors in Gigabyte in comparison with the reference is richer: two DVI, three DisplayPort and one HDMI.


The card support Flex Display technology, offering the most simple auto-definition and configuration of devices in complex multimonitorial configurations of four displays. It is enough to connect them to one of the schemes.


With external identity, the cooling system in Gigabyte GV-N980G1 is still different from the GV-N970G1. The number of heat pipes increased, and the contact itself with the kernel is now carried out through a massive copper base, simultaneously covers and memory chips.


Cooling is unable for both GPU and for power supply circuit. Their contact plate is attack on one of the radiator sections. This certainly improves the cooling of the corresponding components, but also increases the overall heat load on the radiator.


Thermal tubes are six, and five of them with a diameter of 8 mm. The radiator itself is larger and more powerful in comparison with the younger map. Now it is broken into two sections, and the location of the plates is more dense and close. For all criteria, the effectiveness of such cooling should be higher in comparison with Gigabyte GV-N970G1. Ensure only the absence of direct kernel contact with heat pipes.


Plastic casing with three POWER Logic PLD 8010S12H fans is mounted with 80 mm sizes.


Fans are highlighted by the unique design of Unique Fan Blade with grooves on the blades, grooves on the lower edges and the cloth on the outside. Such a special form is designed to increase the density of air flow and increasing the total efficiency of the fans at the same turns.


The plate covering the opposite side of the textolite is not in contact with the electronic components, performing the role of an amplifying element that gives the rigidity of the entire structure.


The printed fee has become more difficult, the number of power phases has been increased. In the area of \u200b\u200bthe power node, the dense installation of components from both sides of the textolite.



The GPU feed system has eight phases instead of four in reference execution. Memory is powered by two phases.


The GM204 graphics processor is surrounded by a massive protective frame.


Standard memory - four gigabytes. It has been recruited by eight Samsung K4G41325FC-HC28 chips.


Gigabyte has the highest factory frequency indicators among those GeForce GTX 980, which we have tested. The basic nucleus frequency is increased to 1228 MHz with Base Clock 1329 MHz. Memory traditionally costs without adjustments, working for 7012 MHz.


The GPU-Z utility rated asic Quality at 72.9%.


Real frequency is kept on the value of peak boost in 1367 MHz, without decreasing lower thanks to efficient cooling and an extended capacity limit. When warming up for 13 minutes, the Unigine Valley Benchmark test on Ultra-quality the kernel temperature did not exceed 63 ° C (indoor 24 ° C). For the top video adapter, this is a great indicator. That's just the speed of rotation of the fans at the same time reached 2500-2600 rpm, so there was a certain hum. Taking into account the low temperature, it is possible to reduce speed in manual mode to an acceptable acoustic level, but the initial settings are difficult to name successful.
With acceleration, Gigabyte did not fail. The memory earned at 4 GHz. The graphics processor managed to overclock up to 1408 MHz at the base frequency at the real boost in 1572 MHz.


For such a mode, it took a voltage to 50 mV. By manual adjustment, the velocity of the fans was increased. Characteristics of tested video cards

The considered graphics accelerator is comparable to the latest defendants of our reviews in the face of the reference GeForce GTX 980, ASUS GTX 980 STRIX OC and MSI GTX 980 Gaming 4G. The old generation is presented by GeForce GTX 780 Ti. From AMD - Radeon R9 290x in Uber mode (MSI R9 290X Lightning) on \u200b\u200bthe corrected frequencies).

The table indicates the official specification of all GeForce. The performance charts indicates the full working core frequency range, including short-term peak BOOST values.

Test results



Studying results Let's start with. Gigabyte in the denial of the faster of the reference by 7% and by 27-31% better than a representative of AMD. The latter even at elevated frequencies is markedly inferior to the hero of the review running in factory frequencies. Performance growth from overclocking 15%.



The potential of NVIDIA flagships is constrained by the performance of the processor, but still a substantial separation from a competitor AMD is visible.



About 3% wins Gigabyte in other irregularities. The difference with the usual GeForce GTX 980 is 7-10%. The most powerful AMD video adapter even at elevated frequencies loses Gigabyte. Growth from overclocking 14%.



Up to 9% difference with reference in Dead Rising 3. AMD's competitor loses 7-8%. Acceleration gives acceleration at 12-13%.



The traditional leadership of Gigabyte is observed in. Advantage over reference up to 9%. The increase from overclocking 14%



The last part of the Hitman in heavy modes critical refers to memory bandwidth. GeForce GTX 980 There is not only RADEON R9 290X, but also the predecessor GeForce GTX 780 Ti. The factory overclocking gives the minimum advantage over the reference without overclocking the memory. When you accelerate Gigabyte faster than all comrades of your series.



The advantage over the usual version of the GeForce GTX 980 at the level of 11%. Radeon is weaker by almost 18%.


Additionally, testing was carried out when the SSAA resource-intensive smoothing is activated. In this mode, Gigabyte brought the difference with the reference to 12%, and the separation from AMD competitor to 19%. Acceleration gives acceleration by 13%.



GeForce GTX 980 slightly loses GeForce GTX 780 TI in
The difference with the closest companion from MSI is almost 3%. The reference is weaker by 10%. Radeon R9 290X loses almost 38%.



The advantage over the reference is less than 8%. AMD competitor reduces gap to 24%. Acceleration increases the results of Gigabyte by 15%.

Energy consumption

For clarity in this comparison, younger models of video cards were added, which did not fall on the graphics comparison of gaming performance.


The survey hero has demonstrated the highest rates of power consumed against the background of the other GeForce of the new series. In the Gigabyte rating, comparable with the GeForce GTX 780, during acceleration, it goes to the level of GeForce GTX 780 Ti. And still, it is less than top Radeon.

conclusions

Gigabyte GV-N980G1 GIGAGY-4GD video card demonstrated the best performance results compared to the analogues of this series with factory frequencies and in acceleration. The operating temperatures in the denomination are very low, as for the top product with the highest factory core frequency. Unfortunately, this is provided not only by improving the cooling relative to the Gigabyte GV-N970G1 Gaming-4GD, but also due to the high speed of blowing fans. The quiet map is not called, but the temperature indicators suggest that it is possible to confidently reduce the revolutions to achieve a comfortable acoustic level. This simultaneously testifies to the fact that in terms of cooling Gigabyte is still inferior to competitors. But acceleration is noticeably better than rivals. Although it will not be possible to implement it in a quiet mode, so the final frequencies for practical everyday use will be no higher than that of other non-reference models. Gigabyte GV-N980G1 Gaming-4GD is an interesting solution with powerful power and excellent acceleration, but not particularly attractive for connoisseurs of silence. If the latter is not critical for you, then the video card can be a good purchase.

That's what I understand the optimization! Excellent FPS increase on all permissions. That's how Ideally, the SLI technology should work.

Several general moments relating to the bundle of Gigabyte GeForce GTX 980. Firstly, such a tandem turned out very powerful. So much that the RADEON R9 295X was not able to sob into the fastest gaming video card today. Secondly, let's calculate how things are at SLI with optimization. Suppose that the FPS increase in percentage ratio to 50% is an unsatisfactory result. In the interval from 50% to 70% - satisfactory. And in a context from 70% to 100% - positive. Test gaming applications in 29 modes were tested (3DMark benchmark was not taken into account). We did the following:

  • Unsatisfactory result - 7 coincidences (24.1% of total modes).
  • Satisfactory result - 5 coincidences (17.3% of the total number of modes).
  • Good result - 17 coincidences (58.6% of the total number of modes).

As you can see, the absolute majority of modes have demonstrated a good performance increase in SLI. And it's great!

Obviously, to collect a SLI-array of high-performance video cards in order to play Full HD, meaningless. FPS in most games and is at a high level. Secondly, as has shown our testing, the speed increases, as a rule, turns out to be very low.

conclusions

It is important to understand that SLI is a technology that depends immediately from several factors. Combining two top video cards, it is necessary that the processor can "pump them". Much depends on the optimization of games, as well as drivers. Today, the application may not support SLI, and tomorrow - on the contrary.

As for performance, then, in my opinion, the meaning in installing the second (third?) GeForce GTX 980 is if you want to play a maximum in WQHD and Ultra HD. In all other cases there will be enough and one graphic adapter.

Finally, the Gigabyte GeForce GTX 980 video card itself left a very pleasant impression. She definitely better than reference: quieter and colder, moreover, it has a very high factory overclocking chip. In general, Must Have! Therefore, the device is awarded to the medal "Editor's Choice".

Packaging and equipment

The video card is sealed into a relatively large cardboard box, the design of which is quite typical for the company's products. On its face, you can find the name of the video card model, the series, the corporate cooling system and the list of supported graphic technologies NVIDIA.

The reverse side of the box is traditionally informative - here it is described about the design of the cooling system and its features, accessories of the video card to the Super Over CLOCK series, video outputs and the capabilities of the video card with four monitors simultaneously using Flex Display technology.

The reliability of the packaging does not occupy, because inside the colored shell is another box - from thick cardboard, and in it, in turn, the insert of the foamed polyethylene is located in the center of which and the video card is fixed. But the equipment is very poor: it includes only two cables for connecting additional nutrition - and nothing else.

It remains to hope that only samples for the press are equipped with such a scant set of components.

A video card is produced in China, and a three-year warranty is provided with it. In Russian stores, this model at the time of the preparation of the article could be purchased at least 2,290 rubles. By the time of publication, it has risen up to 30,720. Nedlyozy, straight to say. Well, let's see, for which the buyer gives such money.

Design and Features of PCB

The cooling system consists of an aluminum radiator with a TRIANGLE COOL technology and a special structure of the roiber on new composite heat pipes with an increased heat transfer rate, an aluminum frame with three advanced fans with an increased volume of air flow and a protective perforated plate on the reverse side of the board.

In total, five copper thermal tubes with a diameter of 8 mm and a diameter of 6 mm are used in the radiator. Thin aluminum plates in contact with them by soldering are riveted on heat pipes.

One section of the radiator is evenly permeated with eight-millionth thermal tubes, while the second of the same tubes are part of the base, and the sixmillimeter permeates the upper face of this section of the radiator.

We particularly note that composite heat pipes are used in the design of the WINDFORCE 3X 600W, in which the capillaries due to the additional layer are provided with a more speed and efficient heat exchange between the components of the radiator.

At the height and quality of the radiator assembly, and the tightness of the heat pipes to the plates, and the quality of the treatment of the plates themselves.

The copper base of the radiator is in contact with the graphics processor through a thin layer of thick gray thermal papers, and thermal staples are applied to contact with memory chips and power elements.

The radiator is cooled with three fans in a metal frame.

On the blades of each of the impeller with a diameter of 77 mm there are five notches and an additional "fin" on the front end.

According to the company's engineers, the blades of such an original form made it possible not only to reduce the turbulence of the air flow injected into the radiator, but also increase its volume at once by 23% compared with the fans with the traditional shape of the blades. The adjustment of the rotational speed of the fans is carried out by means of PWM modulation in the range from 1000 to 4,300 rpm.

In addition, the cooling system windforce 3x 600w is equipped with a blue backlight on the top of the casing.

To check the temperature mode of the video card G1 Gaming 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 an anisotropic filtering level 16x and MSAA-smoothing degree 4X.

MSI AfterBurner version 4.0.0 and utility were used to monitor temperatures and all other parameters. GPU-Z version 0.8.0. All tests were carried out in a closed case. system Blockwhose configuration you can see in the next section of the article, at a medium room temperature 23 Degree Celsius.

The G1 Gaming cooling system is traditionally started with automatic fan speed adjustment.

Auto mode

AMD today will perform a two-processor Radeon HD 7990 and reference AMD Radeon. R9 290X.

We add that the value of Power Limit on all video cards was put up per maximum.

To reduce the performance of video card performance from the platform speed 32-nm, a six-core processor with a multiplier 48, a support frequency of 100 MHz and an activated Load-Line Calibration function was overclocked to 4.8 GHz with raising voltage in the BIOS of the motherboard to 1.380 V.

Hyper-Threading technology activated. At the same time 32 GB random access memory Functioned at a frequency of 2.133 GHz with timings 9-11-11-20_CR1 at a voltage of 1,6125 V.

Testing started on October 26, 2014 was conducted under operating system Microsoft Windows. 7 Ultimate X64 SP1 with all critical updates to the specified date and with the installation of the following drivers:

  • chipset motherboard Intel Chipset Drivers - 10.0.22 WHQL dated 05.08.2014;
  • libraries DirectX End-User Runtimes, release date - November 30, 2010;
  • video card drivers on NVIDIA graphics processors - 344.48 WHQL of 10/22/2014.
  • video Card Drivers on AMD Graphic Processors - AMD Catalyst. 14.9.2 Beta (14.301.1006.0) of 10/24/2014.

The performance of video cards was tested in two permissions: 1920x1080 and 2560x1440 pixels. For tests, two graph quality quality modes were used: Quality + AF16X - the quality of textures in the default drivers with the inclusion of anisotropic filtering level 16x and Quality + AF16X + MSAA 4x (8x) with the inclusion of anisotropic filtering level 16x and full-screen smoothing of degree 4x or 8x, in cases When the average personnel per second remained high enough for a comfortable game. In some games, due to the specifics of their gaming engines, other smoothing algorithms were used, which will be referred further in the technique and in diagrams. 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 Driver Control Panel or. There was also forcibly disabled vertical synchronization (V-SYNC). In addition to the specified, no additional changes in the driver settings were made.

The video cards were tested in two graphic tests and fourteentham games updated to the latest versions on the start of the preparation of the material. However, except standard update Games, there were changes and in the test set itself. The oldest games are excluded Total War: SHOGUN 2 - Fall of the Samurai and Sniper Elite V2, and their place was taken by Sniper Elite III and Middle-Earth in June and September of the current year: Shadow of Mordor. Here is what the list of test applications looks like (games are located in the order of their official output):

If the games implemented the possibility of fixing the minimum frame number per second, it also reflected in 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%, the testing was repeated at least once to get a reliable result.

Results of performance tests

In diagrams, the results of two single-processor video cards on NVIDIA graphics processors - NVIDIA and G1 Gaming - reflected light green lines, and on the AMD graphics processor - Radeon R9 290x - habitual red. Dual-processor NVIDIA GTX 690 and a bunch of pairs are highlighted timno-turquoise Color, and the results of the two-processor AMD Radeon HD 7990 - lilavapouring.

Study and analysis of results will begin with semi-synthetic benchmarks.

  • 3DMark (2013)

  • Crysis 3.

Despite almost two years, which have passed since CRYSIS 3, it is still a very resource-intensive game and is able to uncover the performance of the 2-way SLI even with the most modest graphics quality settings.

A very low minimum FPS is not a feature of SLI, because in this test it is peculiar to all video cards on NVIDIA graphics processors. G1 Gaming faster than the reference video card by 3-6%, and NVIDIA GTX 690 and AMD Radeon HD 7990 are again equal to performance.

  • Metro: Last Light

First, the results with ADVANCED PHYSX activated technology.

And then - when it is turned off.

In both cases, we received the same 2-way SLI performance increase relative to a single video card, and it turned out to be lower than an average of testing, only from 45 to 69%. Otherwise, the differences in the ratio of the results we did not reveal.

  • COMPANY OF HEROES 2

In Company of Heroes 2, the greatest effect of adding the second is achieved with MSAA8X smoothing in a resolution of 2560x1440 pixels.

Much depends not only from the specific game and correct support to it SLI technology, but also from the quality mode or permission. As a rule, when activating smoothing and choosing the maximum possible permission of 2-way SLI works noticeably more efficiently. For example, if on average for all tests in the resolution of 1920x1080 pixels without the use of smoothing productivity growth amounted to only 41%, then in the resolution of 2560x1440 pixels with smoothing - already 75.3%! As they say, feel the difference. However, each of you probably understands that the purchase of two such expensive video cards is obviously not caused by the desire to play them on the monitor with a maximum resolution of 1920x1080 pixels ...

GeForce GTX 990 2x4 GB on average for all other tests may be faster than GTX 690 by size from 46 to 77%, but in some games the difference exceeds 90%. So, with a lower heat dissipation and not too increased energy consumption of the GTX 990 is very interesting. If only the price for her NVIDIA did not overdo it.

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). The measurement was carried out in 2D mode, normal work in Microsoft Word. or Internet surfing, as well as in 3D mode. In the latter case, the load was created using four consecutive switchgear of the Swamp level from the Crysis 3 game in the resolution of 2560x1440 pixels at maximum graphics quality settings, but without using MSAA smoothing.

GeForce, which requires less than 500 watts in the peak of the load.

Conclusion

To begin with - about the video card itself: G1 Gaming is one of the most interesting original versions of the GTX 980 on the market. Despite the high cost, offers a potential buyer very high graphics processor frequencies obtained thanks to the GPU Gauntlet Crystal Sampling System. To coupled with a high-quality element base built on durable components on the Ultra Durable VGA concept, this allowed us to achieve even higher frequencies during acceleration and noticeably increase the performance of the already fast video card. It is impossible not to say about the highly efficient cooling system windforce 3x 600W, which even provides such a high-frequency video card comfortable temperature. At the same time, the noise level of the cooler, as shown by our tests, can be reduced to a minimum. So if you have collected a choice of very fast video cards and efficient cooling with noise level for you matter, then G1 Gaming is ideal for this role.

O 2-Way SLI: this technology A pair demonstrates more than 80- or even 90 percent performance increase in comparison with single video card indicators. It should be understood that we are talking about the most resource-intensive games and their modes using the most "hard" smoothing algorithms in permission not lower than 2560x1440 pixels. Only in such conditions, this bunch of ourselves is entirely justified: enough to look at the results of Hitman: Absolution, Crysis 3, Metro: Last Light, Company of Heroes 2 or Sniper Elite III.

In this regard, our expectations from the intended release of a two-processor GeForce

    The video card is sealed in a relatively heavy medium-sized box, decorated in the Gigabyte G1 Gaming series products. On the front side near the mechanical eye of one of the transformers, the name of the series and the video card model, the cooling system and the list of supported NVIDIA technologies are indicated.

    The reverse side of the box is traditionally more informative: it will tell you in detail the potential buyer about the design of the cooling system and its features, will tell about the accessories of the video card to the Super Over CLOCK series, the graphics processors for which the special selection pass, as well as on video outputs and the capabilities of the video card with four monitors simultaneously .

    At the bottom of the box, the power supply requirement requires a dual BIOS information, Ultra Durable VGA technology and HDMI output.

    Inside the colored shell there is another box of thick black cardboard, and a substrate from foamed polyethylene is inserted into it, in the center of which and the video card is fixed, - not to take reliability. Delivery set as such is missing - inside we found only installation instructions.

    Of course, Gigabyte GEFORCE GTX 980 Ti G1 Gaming serial instances will include a much more complete set of components.

    A video card is produced in China, and a three-year warranty is provided with it. In Russian stores this model Gigabyte at the time of the preparation of the article has not yet appeared, and abroad is offered for 689 US dollars, that is, exactly the same as the original version of Inno3D is also worth.

    In Gigabyte, we decided to change the colors of the cooler casing so that the flagship model differs from, for example, Gigabyte GeForce GTX 980 G1 Gaming, but in general the design has not changed. The entire front side of the video card closes the windforce 3x 600w cooling system with three fans, and the reverse side hides behind the perforated plate.

    From above on the housing, the inscription "WINDFORCE" is visible, equipped with backlight, and two more windows with "Silent" and "Stop" appeared on the side of her. The size of the novelty is 299 × 110 × 41 mm, and weighs the video card 1238 grams.

    Unlike the reference versions of the GeForce GTX 980 Ti, Gigabyte GeForce GTX 980 TI G1 Gaming is not equipped with one, but two dVI connectors. After catching that with such a cooling system in perforations panels with outputs, there is no particular need, Gigabyte engineers decided to expand the functionality of video outputs and, calling this Flex Display solution, the DVI-D DVI-D-D-out (both with Dual Link is supported). At the same time, the three standard for GeForce GTX 980 TI output DisplayPort version 1.2 and one HDMI version 2.0 remained in their places.

    At the same time, the number of monitors simultaneously connected to the video card remains the same equal to four, but now users are available more connectivity options.

    The same scheme was used in Gigabyte GeForce GTX 980 G1 Gaming - it favorably distinguishes the company's products from competitors.

    Two standard connectors for creating SLI configurations are located at their regular places, but instead of six and eight-contact connections of the reference GeForce GTX 980 Ti on Gigabyte GeForce GTX 980 TI G1 Gaming are used two eight-contact.

    It is not difficult to assume that additional food appeared due to the enhanced printed circuit board and increased frequencies of the video card. The fact that the board is really non-standard, we were convinced immediately after removing the cooling system.

    Instead of the power supply system according to the "6 + 2" scheme, which we met on the reference GeForce GTX 980 Ti, the Gigabyte GeForce GTX 980 TI G1 Gaming uses an eight-phase diagram for a graphics processor and two-phase for video memory and power circuits.

    Traditionally, for a Gigabyte, the printed circuit board is built using the Gigabyte Ultra Durable VGA branded concept, which we have repeatedly told, and also complemented by solid-state capacitors on the reverse side of the board, including in the area opposite the graphics processor.

    If you judge the microcircuits on the front and reverse side of the board, the four-channel controller NCP 81174 and two-channel NCP 81172 correspond to the power management of NCP 81172 (both - production on semiconductor).

    In addition to them, the Tree-channel controller INA 3221 produced by Texas Instruments, which is responsible for the monitoring functions.

    The GM200 Graphic Processor Crystal is 601 mm 2 refers to the A1 version, released in Taiwan, but already at the 17th week of 2015 (the second half of April). Note that this is the most "fresh" GPU model GM200 among video cards granted to us for testing.

    It consists of 2816 unified shader processors, 176 textural blocks and 96 raster operations (ROPS) blocks. Thanks special Program According to the selection of Gigabyte GPU GAUNTLET graphics processors and comprehensive testing, the base frequency of the GPU in 3D mode is increased to 1152 MHz, and in the forced mode, it is possible to automatically increase to 1241 MHz.

    This is the same result of the factory overclocking of the kernel, as well as on the previously tested by the ENO3D video card, however, according to the monitoring data, the frequency increased to 1380 MHz, which is 26 MHz above. Note that in the video card specifications on the official page, the OC MODE mode is specified, in which the kernel frequencies should be 1190/1291 MHz. Apparently, there are in mind the frequencies that can be set up using the Gigabyte OC GURU II branded utility. When switching to 2D mode, the GPU frequency is reduced to 100 MHz. The quality of ASIC graphics processor of our video card instance is 77.1%.

    Like all GeForce GTX 980 Ti, Gigabyte GeForce GTX 980 Ti G1 Gaming is equipped with six gigabytes of video memory of the GDDR5 standard, placed on the front side of the printed circuit board in the twelfth microcircuits manufactured by SK Hynix (labeling H5GQ4H24MFR-R2C chips).

    Unlike Inno3D, here the factory overclocking, unfortunately, was not, therefore, the effective frequency of memory is equal to the standard 7012 MHz, which, with a 384-bit tire, the exchange can provide theoretical bandwidth of 336.6 GB / s. In 2D mode, the memory frequency is reduced to 648 MHz.

    Via latest version GPU-Z Utilities Let's look at the Gigabyte GeForce GTX 980 Ti G1 GMING Specifications ...

    ... and go to the study of its cooling system.

    Gigabyte GeForce GTX 980 TI G1 GMING video card is equipped with the most powerful company cooling system - WindForce 3x 600W.

    Interestingly, in thickness, this cooler does not go beyond two-billive design, which means that theoretically, the video card can be used in any SLI configurations.

    The cooling system consists of an aluminum radiator with the TRIANGLE COOL technology and a special structure of the roiber on new composite heat tubes, an aluminum frame with three optimized fans with an increased air flow volume, as well as the protective plate on the reverse side of the board.

    The radiator uses five copper thermal tubes with a diameter of 8 mm and one diameter of 6 mm. Thin aluminum plates in contact with them by soldering are riveted on heat pipes.

    Especially lay out so high quality The radiator and the accuracy of the soldering of heat tubes to the plates.

    One section of the radiator is evenly permeated with eight-million thermal tubes, for the second section, these tubes are the base, and the sixmillimeter passes along the upper boundary of the radiator.

    In the design of Gigabyte WinDForce 3x 600W, composite heat pipes are used, in which the additional layer of capillaries is provided with a more speed and effective heat exchange between the components of the radiator.

    We add that the copper base of the radiator contacts the graphical processor through a thin layer of thick gray thermal stas, and thermal staples are used to contact with memory chips and power elements.

    The radiator is cooled with three fans fixed in a metal frame.

    On the blades of the impeller with a diameter of 77 mm, five notches are made, teeth in the backside and an additional "fin" on the front edge of each blade.

    According to Gigabyte engineers, the blades of such a form allowed not only to reduce the turbulence of the airflow into the radiator, but also increase its volume at once by 23% compared with the fan indicator with the traditional form of blades. Adjusting the speed of rotation of the fans, according to the monitoring data, is carried out by means of PWM in the range from 0 to 4220 rpm - in the mode of minimum 3D load or 2D fans stop completely.

    In this version of the cooling system GIGABYTE WINDFORCE 3X 600W not only the backlight is used on the top edge of the casing, but also two more windows with backlit are added, and both have very speaking names - Silent and Stop.

    Version 4.1.1 and utility

    In efficiency Here, the result is no better - 72 degrees Celsius against 65 at Inno3D, but we will not forget that Gigabyte GeForce GTX 980 Ti G1 Gaming The cooling system blocks only adjacent to the video card pCI-E slot, while Inno3D overlaps two such slots. Yes, and in comparison with the reference version of the GeForce GTX 980 Ti, the winnings are evident.

    Since we still have a reserve on the temperature of the GPU, we have identified a subjectively comfortable on the noise level of operation of the Gigabyte WindForce 3x 600W fans, fixing their speed by 38% of the power, or 1600 rpm, and conducted tests again.

    Maximum speed (4220 rpm, x3)

    The noise level is very high that we will now confirm the measurement results.

    Measuring the noise level of cooling systems of video cards was carried out by electronic noiseomer "Octave-110a" after an hour of night 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 exclusively 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. Motherboardwhere the video card was inserted with a cooling system installed on it, was placed on the corner of the table on a polyurethane foam substrate. The lower boundary of the measurements of the noiseomer is 22 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.

    On a graph with noise level Gigabyte GeForce GTX 980 TI G1 Gaming, we included the noise level measurement results of the noise level just tested inno3d iChill GeForce GTX 980 TI X4 ULTRA and the reference version of GeForce GTX 980 Ti. We add that the vertical dotted lines of the corresponding color marked the upper bounds of the cooling system during their automatic PWM adjustment (in Gigabyte two such lines, since, in addition to automatic adjustment, we noted 38% of the cooler power under which the temperature regime tests conducted). That's what results we got.

    Gigabyte GeForce GTX 980 Ti G1 GEFORCE GTX 980 TI G1 GEFORCE GTX 980 TI G1 GEFORCE GTX 980 TI G1 GEFORCE GEFORCE GTX 980 TI X4 Ultra, that is, theoretically its cooler with equal fan speeds should be quieter. However, in fact, this is not the case, because if in INNO3D, with automatic speed adjustment, the fans are spinning up to 1380 rpm, then in Gigabyte they accelerate up to 2490 rpm. Of course, no silence or at least comfort in terms of noise level is not to speak here, unfortunately. The video card is tangible noise. It is noticeably correcting the situation manual fixation of the fan speeds by 1600 rpm - this allows the Gigabyte windforce 3x 600W to reach one noise level with the Inno3D Herculez X4 Air Boss, but as you can see above, the temperature of the video card in this mode is very high. So if on the Gigabyte GeForce GTX 980 G1 Gaming, we were more or less satisfied with the temperature mode of operation while manual fixation of the fan speed, then we cannot say no longer on the new Gigabyte GeForce GTX 980 TI G1 GEFORCE GEFORCE GM200. Nevertheless, we note that the original Gigabyte video card is functions quiet than the NVIDIA reference sample.

    Gigabyte GeForce GTX 980 Ti G1 Gaming has the same factory core frequency, as well as Inno3D ICHILL GeForce GTX 980 Ti X4 Ultra, but a reinforced printed circuit board with an increased up to 130% nutritional limit instead of 111% in Inno3D and reference versions of GeForce GTX 980 Ti. This allowed us to hope for a more successful acceleration of the graphics processor. Our expectations were to some extent justified, since the base frequency of the GPU could be increased by another 130 MHz, or by 11.3%, and to the basic frequency of the reference version of the GeForce GTX 980 Ti, the frequency increase was 28.2%. In turn, the effective frequency of video memory without loss of stability and the appearance of image defects, we increased by 1220 MHz, or 17.4%, which is also higher than the result inno3d.

    After overclocking the total frequencies of Gigabyte GeForce GTX 980 Ti G1 Gaming amounted to 1292-1381 / 8232 MHz.

    The speed of the fans in the automatic adjustment mode has grown from 2490 to 2680 rpm - it is not so much, given the fact that in any of these modes of the video card noticeably noise.

    This is the original version of the GeForce GTX 980 Ti from Gigabyte. Now let's find out what its performance and how effective NVIDIA SLI technology is effective on a pair of "freshly baked" flagship video cards.

    Finally, all manufacturers have released their own versions of GeForce GTX 970 and GTX 980 video cards based on a new graphic processor. Of course, in most cases, users encounter reference circuit boards and original cooling systems.

    This statement applies mainly to the older model, the youngest was initially deprived of a reference circuit board, or rather NVIDIA recommended using the GeForce GTX 980 fee. But, as you understand, it is expensive and unattractive, if you can save on wiring and components. Therefore, manufacturers began to develop the design of the GTX 970 on their own, sometimes borrowing the GTX 980 cooling system.

    Recently, several graphic accelerators GeForce GTX 970 and GTX 980 visited our laboratory, now it's time to introduce our readers with them. And first we will look at the model Gigabyte Series G1 Gaming.

    Gigabyte GV-N970G1 Gaming-4GD

    Despite the fact that Gigabyte GV-N970G1 Gaming-4GD has already visited the hands of one of our authors, in this review she fell not by chance, since the similarity of its cooling system with a GV-N980G1 Gaming-4GD cooler can play a cruel joke with the buyer.

    Per external species (or rather, the casing) is hidden big differences, and you should not succumb to this trick. Gigabyte was so skillfully used this approach that even the reverse side casing applies almost identical design. Otherwise, these are copies: Couple DVI outputs (DVI-I / DVI-D), one HDMI and three DisplayPort. Moreover, HDMI is initially declared NVIDIA as supporting standard 2.0 (i.e. compatible with TVs and monitors 4K @ 60Hz). But what was the disappointment of the first buyers, when only selective compatibility was found.

    To blame here, in my opinion, both sides: TV manufacturers, stating the HDMI 2.0 standard, did not bother checking hardware compatibility, and NVIDIA when released new video card Implemented this in accordance with the new version not yet adopted. As a result, everything is suffering.

    Gigabyte GV-N980G1 Gaming-4GD

    Externally, it is copied to the smallest detail GV-N970G1 Gaming-4GD, but its mass is much harder. The departure lies in a more dense placement of the edges of the cooling system and the greater the heat pipes. And the printed circuit board itself is comparable to the size of the reference version of NVIDIA. In particular, it repeats the basic placement of the elements, but some of them are replaced by branded.

    However, it did not make Gigabyte GV-N980G1 Gaming-4GD become completely silent. Yes, the eternal and beaten the theme of the pickels touched the senior Maxwell solutions fully.

    Printed circuit board

    Gigabyte GV-N970G1 Gaming-4GD

    Personal vision of Gigabyte engineers has expressed in the desire to create an exclusive printed circuit board, which is no bit similar to the reference GeForce GTX 980. Of the advantages, we immediately note a large supply for nutrition (6 + 8 PIN) and power connectors deployed in the opposite side so that the radiator does not interfere with the connection. .

    The main part of the VRM is moved forward a video card.

    The power of the graphics processor corresponds to six phases, which is more than enough for serious overclocking.

    Gigabyte engineers are constantly recycled and modified, and therefore often use proven components. Alas, but from the high-frequency pic of throtters, their measures did not save neither GeForce GTX 970, nor GTX 980. The only solution is still activating V-SYNC.

    The PHIM controller remained the same - NCP81174, it is also installed on all GeForce GTX 980. To universal sadness, control voltage on video cards, as well as the energy consumption threshold, it became very difficult. More precisely, if it remains possible at all.

    Now a part of the code in the drivers actively monitors the energy consumption of the video card and counteracts the overestimation of parameters above a certain value. Treatment methods are immediately two: BIOS modification and hardware voltmode; It is impossible to do with the software method. Although NVIDIA itself has significantly expanded the corridor of permissible frequencies, stresses and power consumption.

    In general, for ordinary users, the situation is seriously complicated, and for the overclocker enthusiasts to work the soldering iron over the printed circuit board - the case is ordinary.

    Eight samsung production microcircuits are planted on both sides. They are calculated on the frequency of up to 1750 MHz (effective frequency of 7000 MHz), the width of the tire is 256 bits.

    The combination of the microcircuits of the South Korean manufacturer and competent engineering always brought its fruits. So, the memory on GeForce GTX 970 and GTX 980 video cards excellently accelerates to 1900-2000 MHz.

    Maxwell's graphics core released in 2014. As usual, the marking uses a secondary number that denotes the GPU class (100-200-400), and the higher the decision. The "200" number is assigned GeForce GTX 970, "400" means GTX 980.

    Gigabyte GV-N970G1 Gaming-4GD video card rated frequencies are 1178 MHz for GPU (GPU Boost to 1329 MHz) and 1750 MHz for memory. The characteristics are impressive, let's see a little later, as the BOOST frequency is withstanding in reality.

    Gigabyte GV-N980G1 Gaming-4GD

    The power system "4 + 1" reference version of GeForce GTX 980 has become "8 + 2" on Gigabyte GV-N980G1 Gaming-4GD. Two 8Pin power connector used, and for the output to monitors there was a place for special keys (visible on the left side of the video card).

    Personally for GV-N980G1 Gaming-4GD developers Gigabyte completely revised the design, nothing remains from the reference.

    Even for memory two phases are assigned. Perhaps this will help the video card in acceleration? We will definitely check, but there should be no doubt. With such facilities would not let the BIOS image. And it turns out that they have gone for a long time, but in the end they did not go fast.

    From manufacturers, no one risked replacing the standard NCP PWM controller. And it is indicative migrates from one graphic accelerator to another. The reason lies in the support of voltage table drivers. If you specify the goal of installing a more advanced PWM controller, you will have to certify it from NVIDIA.

    What GeForce GTX 970 is that GTX 980 in the denomination should be equipped with a frequency chips with a frequency of at least 7000 MHz, so we will often encounter identical memory on video cards. Is that there eight samsung production chips are planned from the front side.

    The graphics processor released at the 32nd week 2014. The index "400" tells us about accessories for the senior version of Maxwell.

    The nominal frequencies of the Gigabyte GV-N980G1 GAMING-4GD video card are 1228 MHz for GPU (GPU Boost up to 1329 MHz) and 1750 MHz for memory. The base frequency is even greater than the GV-N970G1 Gaming-4GD, the boost is the same. But we know how the situation in reality may change.

    Cooling system

    Gigabyte GV-N970G1 Gaming-4GD

    Differences lies in the details - they play an essential role. Subjectively in front of us are two similar video cards. The external length is the same, size and type of fans - the same, rear protective plate - the same, then what items are we talking about?

    The inner structure of the cooling system GV-N970G1 Gaming-4GD is seriously simplified. Four heat pipes, wide placed edges, direct contact, total communication Graphic core and power system are all characteristic of the younger model. Thanks to the intercostal distance, one can judge the smaller air resistance (and as a result - a smaller level of noise), but let's see if engineers were able to benefit from geometry or not.

    While you can say only one thing - dismantling and disassembling CO do not pull on a high rating due to certain difficulties. To remove the main radiator, you need to unscrew not only the four screws, but also a couple more, passed through the casing. And only then you can get to the attachment of the protective plate. But to the fans get it easier.

    I would like to introduce some subjective assessment, like if IFIXIT, so that we can compare the thoughtful cooling systems of various manufacturers. So, the cooler Gigabyte GV-N970G1 Gaming-4GD deserves six points out of ten. And be careful with heat-conducting ribbons, their thickness is too small to withstand with a dozen disassembly.

    Gigabyte GV-N980G1 Gaming-4GD

    This model repeats the general design rule, but does not copy the insides. Before us with albeit without a cherry (and with a cherry, you can call the evaporative chamber, once used in Gigabyte video cards), but well-designed quite competently.

    Six heat pipes, five of which are 8 mm in diameter, maximally use the radiator area. For contact with the graphics core, a single and large plate of copper is involved. With it in contact and memory chips. And again there are questions to the quality of heat transfer materials. Gaskets are very thin! IN unified system Cooling with GPU combined and power system. It is worth noting that the distance between the edges is critical, there is a chance that the fans do not have enough strength to blow them.

    And to shoot and disassemble the system is still hard. Therefore, the overall assessment of the design is only eight points out of ten.
