i5 processors socket 1151. Intel Core i5 processors for LGA1151 platform

Impact of RAM on system performance

Introduction

It is difficult to argue that the growing dollar exchange rate has seriously affected buyers of computer components, because in just a year, hardware has risen in price by 30-60%. What are manufacturers doing, what steps are they taking to maintain their positions in the market? Who responded most quickly to the suddenly unfavorable situation? Answering these questions will be easier if you look at the situation as a whole.

ASRock, ASUS and MSI are the top trio of mainstream motherboard vendors, with almost 70% market share. And the tastiest part of the pie is the Intel Skylake CPU segment, with fresh processors increasing the chances of tempting buyers. But if earlier users forgave Intel's pranks and changed platforms when switching from one type of CPU to another, now people have become more picky.

Of course, technology does not stand still, but this time, instead of one intelligible step, we got only its semblance. For example, try to immediately find five differences between the motherboards of the previous generation and the current one. Yes, new models are equipped with USB 3.1, M.2 or U2 connectors, but without them it was possible to assemble a solid computer. Why, then, take an expensive motherboard, if you can get by with a more modest version? Perhaps overclocking will say its weighty word when choosing? And here Intel tried to cut off the oxygen to customers as much as possible.

Manufacturers, seeing a decline in consumer demand, began to introduce new features, including undocumented ones. But after that, Intel elevated the principles of segmentation of its products to the absolute - if you want to overclock now it's not enough just the CPU, you also need a motherboard based on the Intel Z170. And there is no doubt that under the onslaught of the vendor, manufacturers will sooner or later remove the overclocking capabilities of processors without the “K” index. Apparently, right now it is important not to miss the moment, choose something suitable among hundreds of motherboards and stop updating the BIOS.

The aforementioned trinity also did not sit idly by and gradually saturated Russian retail with more affordable models. And almost all of them have already been described earlier in a series of materials, divided into sets of system logic:

Budget options on Intel H110;
Available models and solutions a class higher on Intel B150;

Testing modern Core i3 processors, we noted that the level of performance demonstrated by representatives of this family has noticeably changed largely due to the fact that the manufacturer has ceased to “clamp” clock frequencies too much. A similar state of affairs was noted in the top segment, where two peaks are clearly distinguished in the form of the "old" i7-4790K and the "new" i7-6700K, fortunately, in their case, the clock frequencies were "set aside" 4 GHz, which is generally not typical for Intel processors. So much so that since the release of the 4790K, the "overclocker" Core i7 simply ceased to intersect with the "regular" family, which made them more interesting for those users who are not interested in overclocking. And what about the Core i5 segment?

In principle, for many buyers, these processors are of maximum interest. The reasons for this are simple - the main sales on the market are in the $80-$200 segment, i.e. any Core i7, for example, these are already processors in any design not for all to the same extent as Celeron or junior Pentium. Core i3 are actively promoted, which are mid-range solutions (fortunately, the price matches), while Core i5 at the same time turn out to be an interesting compromise between the desire to get a quad-core processor and the reluctance to pay too much for it. As we have seen on average, younger modern Core i5 in terms of performance with older Core i3 already intersect, but this is an average: in some tasks that “gravitate towards multithreading”, they are still faster, despite a significant lag in clock frequency. However, you can compensate for this without such significant costs: in principle, the price difference between the Core i5-6600K and i5-6400 is approximately equal to that when comparing the same 6400 with even the youngest Core i3-6100. So if there are people who diligently reach for "at least some" Core i5, then there will be those who prefer the older model of this family. Especially when purchasing a new computer as a whole, the costs of which significantly exceed the cost of the processor itself, making the choice of a powerful model psychologically easier. It is more difficult with modernization - in fact, in this case, you can only count on a performance increase due to "intensive methods" in the transition from generation to generation, since clock frequencies practically did not grow here. It is enough to compare the same 6600K with 2500K five years ago - some 200 MHz at both ends of the range, when the Core i3 or "K" modifications of the Core i7 scored up to 500.

In general, in this segment, everything should be quite “smooth and calm”. However, how interesting. So today we just decided to study the older models of two and a half Core i5 lines, initially realizing that no "miracles" could be found.

Why are we talking about two and a half rulers? Because the desktop Broadwell does not pull on a full-fledged one - there are exactly two “desktop” models: one Core i5 and one Core i7. Last, as we have already seen, could become the "flagship LGA1150", if ... If it worked on all boards, if a new platform had not appeared in just a couple of months, if the "steroid" 4790K had not been released a year before it. However, the Core i5-5675C is devoid of such a problem - as we noted above, both 4690K and 6600K do not break away from it so much in frequency. At the same time, the presence of a cache memory of the fourth level sometimes even i7-5775C compensated for its lagging behind 4790K (very noticeable), so that the "younger brother" may be the second, or even the first in its segment. Even in general-purpose applications - if we focus on the video core, then there are still no similar models for LGA1151 at the moment. It is clear that when purchasing a computer mainly for games, you need to buy a discrete video card, but if necessary, you can (and, in this case, you need to!) Save money on the processor, but it happens when you just need something compact, not too voracious, but capable of at least relatively successfully coping with at least five-year-old hits without question. What makes this processor still relevant.

Unlike 4690K, although the latter may be useful to those who already have a system on the LGA1150, the performance is no longer enough: for example, the tasks being solved have changed a little. In this case, replacing only the processor is, of course, easier and cheaper than switching to a new platform. And in some markets of developed countries, the “old” one can already be given with significant discounts. Here are at least two reasons why you should not write off this processor (especially its slightly cheaper "twin brother" with locked multipliers) for the time being. In the rest - it is better to pay attention to the new platform. Accordingly, there will be two processors for it - the youngest Core i5-6400, since we already know it well and the fastest i5-6600K at the moment.

Test Methodology

The technique is described in detail in a separate article. Here we briefly recall that it is based on the following four pillars:

And the detailed results of all tests are available in the form complete table with results (in Microsoft Excel 97-2003 format). Directly in the articles, we use already processed data. In particular, this applies to application tests, where everything is normalized relative to the reference system (as last year, a laptop based on Core i5-3317U with 4 GB of memory and SSD, with a capacity of 128 GB) and grouped by the areas of application of the computer.

iXBT Application Benchmark 2016

Here is the situation immediately, the possibility of which was announced a little higher - the fastest Core i5 turned out to be 5675С. However, it cannot be said that its advantage is so great, firstly. Secondly, it will be smaller when using a discrete graphics card - these GPU programs are sometimes at the very least used.

As well as a group of applications for working with photos. However, there is a complete triumph of Skylake in it - not even because the 6600K turned out to be the fastest, but because the slowest Core i5-6400 in the family got close to the 4690K, which was officially the fastest Core i5 just a year ago. In general, we have a growing suspicion that the specifics of recent years (and the main goals in the development of new microarchitectures) can bring major benefits to buyers of mid-range desktop processors. Or budget. But the top segment is updated only insofar as, and older Core i5 models are also already affected.

We have already noted some "dislike" of the previous version for Broadwell processors with L4 cache - as you can see, nothing has changed. But the models under LGA1151, on the contrary, have clearly accelerated. However, not only in this program, so it may turn out that the error corrections and other “little things in life” that have occurred in the field of system software have also affected.

Which did not affect this program - the results are very similar to those obtained last year in its earlier version. In principle, a completely predictable phenomenon - abrupt changes without a significant change in the program code are just less likely. So we are seeing the usual "creeping progress" and nothing more.

As well as in this case. Actually, taking into account the similarity of processors in organization, there is nothing surprising in the fact that they behave approximately the same in different code. Significantly different from the other i5-5675C, but in two ways: L4 and GPU pull it forward where possible, but lower frequencies than the other two tops - back and always. The end result in his case may vary within the range of 4690K-6600K. And in special situations - and marry him.

For example, like here. But this is just the ideal option for a more powerful hierarchical memory system - it is clear that L4 is faster than RAM. And if you also remember its huge (by the standards of caches) capacity, then the result is all the more unsurprising.

But file operations are performed in approximately the same way, since they almost do not depend directly on processors of this class.

As we already wrote, in Broadwell there were enough optimizations to overtake Haswell even at a lower clock frequency, and there is also a susceptibility of the program to delays and bandwidth of the memory system. In general, the older Core i7-4790K and 6700K were greatly "saved" by a serious advantage in clock speed, however, as mentioned above, there is no such advantage in the Core i5 family. With all the ensuing consequences.

Ultimately, we come to the conclusion that even in general-purpose applications, the 5675C still looks good - it overtakes 4690K much more than it lags behind 6600K. Unfortunately, this line has not received significant distribution, and we have not yet seen its further development, although it would be interesting. As a result, we come to a slightly strange state of affairs. 4690K is generally clear why it is needed - it is somewhat cheaper than the rest of the test subjects, and it is well suited for upgrading almost any system with LGA1150 (you never know - the Core i3 bought two years ago began to "miss" after replacing the video camera, for example), so now sells well. Especially taking into account the fact that it is calm and good for overclocking (still popular in certain circles). The Core i5-5675C, on the other hand, cannot be installed on any motherboard, and it costs as an older (in the class) solution for a newer and “promising” platform. As a result, you can buy, of course, but measure it three times. However, it is not this that hits all three today's heroes the most, but the prices for the lower line processors for LGA1151 - 6400 and their neighbors. As you can see, they are not so much slower, they are all just as "promising" and noticeably cheaper. As a result, it turns out that the older Core i5 can only be useful for overclockers, since their clock speeds have not been growing for a very long time. Unlike the Core i7, where for two years the top model is really the top model in any use case.

Energy consumption and energy efficiency

Another strong point of the younger Core i5 is the extremely moderate appetite. Inherent and older, despite the formally high official heat pack, but less pronounced. The younger ones are already easily limited to amounts of energy that not so long ago were sufficient only for dual-core models (and even earlier - only for some of them).

Accordingly, if we remove the results of the Core i5-6400 from the diagram, we see a beautiful and even ladder with approximately equal steps corresponding to the change of generations. For the i5-5675C, even winning, but due to a change in the technical process. However, it is worth taking into account not only the older, but also the younger processors for LGA1151, as it suddenly turns out that without changing the production standards, you can achieve very good results, if you do not chase performance too much. Actually, this is what made the older Broadwell models a niche solution almost immediately: the practical readiness of a more efficient new microarchitecture did not leave these processors a chance for a long and happy life.

iXBT Game Benchmark 2016

However, this development of events gives reasons not only for joy, since so far only processors with GT2 GPUs are on sale for LGA1151. In practice, as we can see, this is the same level of performance as that of the "socket" Haswell, but cannot be compared with the GT3e Broadwell (we decided to do without detailed results today, since have seen them many times, and they are also in the table). However, if you buy a computer, focusing on gaming, it does not matter much - anyway, you can’t do without a decent discrete video card. It's better to save just on the processor - a pair of Core i3-6100 with, for example, the Radeon R7 370 will smash any modern integrated graphics shattered and in half. But if the priority is the compactness of the system, and games - insofar as, this is where such a solution would come in handy. But it exists so far only for the platform leaving the market.

Total

So what do we end up with? As we have already established, during their existence in the "historical period" processors of the Pentium and Core i3 families have noticeably increased their performance due not only to intensive methods, but also to a banal increase in clock frequencies. In principle, they were ready for this before, however, the manufacturer specifically limited these models in order to avoid unnecessary competition with the more expensive Core i5. A similar approach was applied to the Core i7, only the clock speeds of not all models increased there - it’s just that in 2014 the “overclocker” series separated from the main family, “passing” the 4 GHz mark. But the Core i5 actually remained at the mark reached five years ago with all the ensuing consequences. Of course, the productivity of the representatives of this family grew, but at a much slower pace - only due to architectural changes. Or thanks to the introduction of another level of cache memory, which has not yet been implemented within the LGA1151. However, the approximate effect of this can be estimated - as we see, it is not so small.

Hello tech blog readers. Today I will tell you which processors are suitable for socket 1151 (Skylake, Kaby Lake), as well as 1151v2 (Coffee Lake). In this article we will try to talk about the most powerful, inexpensive and cheap Intel Core, Pentium and Celeron chips.

The list of CPUs will be listed in order to give you a more accurate idea of the models on the market.

And yes, it's worth making an important clarification: the LGA1151 socket is not backward compatible with the 1150 and does not support Xeon server processors.

Processor compatibility table

Socket 1151 from Intel is very insidious in its essence, since it has 2 versions: the first supports chips of the 6th and 7th generations, and the second only supports the 8th. In relation, the picture is much simpler, but it is not about him.
Let's see which ones, as well as i3, i7, Pentium and Celeron, are capable of running on 1151 Gen 1.
Now let's look at the line of chips that will fit the motherboard with socket 1151v2.
In 2018, 9th generation CPUs were added to the previous list.

The best processor for its price

And now the most interesting part of the comparison. We have indicated which processor fits a particular socket. Now it remains to decide on the model of the chip itself. If you want to learn more about the CPU, we recommend reading this article.
And now let's go through the brightest representatives of the 6th, 7th and 8th generations:

skylake– Intel i5 6400T engineering sample. At one time, this processor made a lot of noise, because it had an extremely low cost, 4 productive cores with a frequency of up to 2.8 GHz and a very modest heat pack of 35 watts.

Kaby Lake– Intel Pentium G4620. The so-called "Hyperpen" became a cult among gamers at the time of release, as it offered the functionality of the Intel Core i3-7100 at a significantly lower cost. It is also worth mentioning the peppy mid-range i5-7400 and the top version of the i7-7700k, which has 4 cores and 8 data processing threads. To this day, the stone is considered a relevant, powerful and interesting solution for progressive systems, and also supports overclocking up to 5 GHz by a multiplier.

Coffee Lake– i5-8400. The advent of the 8th generation of Intel chips added not only a new socket, but also 2 additional cores of each line, with the exception of Celeron and Pentium. Having a 6-core processor that can automatically increase the frequency from 2.8 to 4 GHz is a very successful investment in the future and therefore I recommend it boldly (for i5 prices, you can find out about this (especially since this discounter is well known to many as reliable and verified seller.

Difference between1151 and 1151v2

It has long been no secret that a processor socket designed for chipsets of the 100th and 200th series is completely incompatible with the 300th. And it's not even that Intel wants to make more money. The introduction of additional cores forced engineers to radically redesign the power supply scheme of Coffee Lake processors in order to ensure stable operation of the chips, even under extreme overclocking.
Key changes have been made to the VCC (power) and VSS (ground) pads. At the same time, the number of previously reserved RSVD contacts was slightly reduced. Thus the situation is as follows:

	Skylake/Kaby Lake	coffee lake
VCC	110	128
VSS	364	378
RSVD	46	25

As you can see, it is physically impossible to "make friends" of old chips with new motherboards, just like plugging a Chinese plug into a European socket. Yes, there are enthusiasts who managed to get Kaby Lake on the Z370 by modifying the BIOS, but the lion's share of the functions in this case was unstable, and the rest were completely absent.

So if you have a lot of free time - you can try, but I strongly do not recommend doing this.

I hope that the article was useful to you, so comment, share with your loved ones. See you in new articles. Bye.

Socket 1151: which processors are suitable

Socket LGA 1151 is the current socket for installing Intel processors. It is on Socket 1151 that all the latest consumer class Intel processors are installed. In this article, you can find out which processors are suitable for Socket LGA 1151 and what you need to do in order not to make a mistake when buying a processor.

So, Socket LGA 1151 is a socket for Intel processors with Skylake, Kaby Lake and Coffee Lake architectures.

Skylake is the sixth generation of the Intel Core processor microarchitecture. According to the "tick-tock" strategy followed by Intel, this architecture has received significant changes and improvements, but without switching to a new process technology. Like the Broadwell architecture, the Skylake architecture uses a 14nm process technology. The first Skylake chips went on sale in August 2015. The main features of the Skylake architecture are: Thunderbolt 3.0 support, support for 512-bit AVX 3.2 vector instructions, SATA Express support, a new DMI 3.0 bus, and an integrated image processor.
Kaby Lake is the seventh generation of the Intel Core processor microarchitecture. According to the tick-tock strategy, Kaby Lake is an improved version of the Skylake architecture on the same 14nm process technology. The first processors of this generation went on sale in early 2017. The main features of the Kaby Lake architecture are: USB 3.1 support, Intel Optane memory support, support for HEVC (H.265) and VP9 video encoding formats, support for HDCP 2.2 technology, official compatibility only with Microsoft Windows 10.
Coffee Lake is the eighth generation of the Intel Core processor microarchitecture. According to the tick-tock strategy, the Coffee Lake architecture is an improved version of Kaby Lake using the same 14nm process technology. The first processors of this generation began to be sold on October 5, 2017. The main features of the Coffee Lake architecture are: an increased number of cores, Turbo Boost 2.0 technology, support for USB 3.1 second generation at speeds up to 10 Gb / s, support for Intel Wireless-AC, support for the next generation of Intel Optane.

Below you will find a list of all processors that were released in the Socket 1151. This information can be used to initially select a processor for the motherboard. But, before deciding to buy a processor, you need to check on the website of the motherboard manufacturer whether the processor you have chosen is supported by your motherboard. Since the coincidence of the socket on the motherboard and processor does not mean that they will work together. For example, 8th generation Core (Coffee Lake) processors can only work with 300-series chipsets. The situation is similar with server Xeons, they only work on motherboards with server chipsets.

We also need to remind you that at the time of this writing, Socket LGA 1151 is an up-to-date platform and new processors may still be released to it in the future. If such processors appear, the information in the article will be updated.

How to check processor support on the manufacturer's website

As we wrote above, the ability to install a processor on a motherboard does not guarantee that this processor will work with it. Therefore, before buying a processor, you should always look at the list of supported processors on the website of the motherboard manufacturer.

This is done very simply. First you need to find out the manufacturer of your motherboard and the exact model name. This information can be obtained in the CPU-Z program under the "Mainboard" tab.

After that, you need to study the information on the website of the motherboard manufacturer. There should be a list of supported processors. You can usually find this list in the "Support" or "Support" section.

Processors from this list are 100 percent supported by the motherboard and you can safely buy them.

Which processors are suitable for socket 1151 and 1151v2

The list of CPUs will be listed in order to give you a more accurate idea of the models on the market.

And yes, it's worth making an important clarification: the LGA1151 socket is not backward compatible with the 1150 and does not support Xeon server processors.

Processor compatibility table

Socket 1151 from Intel is very insidious in its essence, since it has 2 versions: the first supports chips of the 6th and 7th generations, and the second only supports the 8th. With regard to the AM3 socket, the picture is much simpler, but this is not about him.
Let's see which i5 processors of different generations, as well as i3, i7, Pentium and Celeron processors, are capable of running on 1151 Gen 1.
Now let's look at the line of chips that will fit the motherboard with socket 1151v2.

The best processor for its price

Skylake - Intel i5 6400T engineering sample. At one time, this processor made a lot of noise, because it had an extremely low cost, 4 productive cores with a frequency of up to 2.8 GHz and a very modest heat pack of 35 watts.

Kaby Lake - Intel Pentium G4620. The so-called "Hyperpen" became a cult among gamers at the time of release, as it offered the functionality of the Intel Core i3-7100 at a significantly lower cost. It is also worth mentioning the peppy mid-range i5-7400 and the top version of the i7-7700k, which has 4 cores and 8 data processing threads. To this day, the stone is considered a relevant, powerful and interesting solution for progressive systems, and also supports overclocking up to 5 GHz by a multiplier.

Coffee Lake - i5-8400. The advent of the 8th generation of Intel chips added not only a new socket, but also 2 additional cores of each line, with the exception of Celeron and Pentium. Having a 6-core processor that can automatically increase the frequency from 2.8 to 4 GHz is a very successful investment in the future and therefore I recommend it to you (and at the same time an interesting offer for you - Intel Core i5 8400 + Free shipping).

Differences between 1151 and 1151v2

So if you have a lot of free time - you can try, but I strongly do not recommend doing this.

What are the prospects for the socket now

Unfortunately, it seems that all the stones have a locked multiplier, which practically makes it impossible to overclock. However, the models with the highest frequency may well be considered the initial gaming decision. Processors with 8 and 10 cores, but a low frequency, are well suited for work.

Three-channel DDR3 memory will allow you to get closer in speed to the initial two-channel DDR4. At the same time, DDR3 ECC modules are now the most cost-effective.

The main problem now is the lack of quality motherboards, but we can hope that the Chinese will quickly expand production, as they did with socket 2011. The first Chinese motherboards are already on sale.

A small summary

Apparently, we have a simplified version of the 2011 socket.

Advantages:

Cheap processors and RAM
Tri-channel memory
Budget gaming build will be cheaper than lga2011

Disadvantages:

There are few motherboards and they are still quite expensive
Not all processor models can be easily found on sale
No stones with unlocked multiplier, almost no overclocking
Less space for further upgrades

Intel processors. Performance rating within the LGA1151 platform

This article will discuss the most current Intel processors. The rating of their performance, given below, will indicate whether a particular model belongs to a certain niche in the semiconductor chip market.

Celeron are the least powerful desktop processors from Intel. Their performance rating indicates that they are best suited only for use in office computing systems, which are capable of solving only the most basic tasks: text and spreadsheet programs, web browsing, multimedia playback and reading books in electronic form.

This family of chips includes 3 models: G3930T, G3930 and G3950. The key difference between the two is the clock speed value. The younger model operates at 2.7 GHz, the middle one - at 2.0 GHz and the older one - at 3.0 GHz. Among other features of this series of CPUs, it is necessary to note the presence of 2 computing modules and a third-level cache memory of 2 MB. The price for the younger models is $42, and the older one is $52.

Average level

The Pentium and Core i3 are mid-range Intel processors in terms of performance and cost. The rating of these semiconductor solutions indicates their similar affiliation. Pentium chips are labeled G45XX or G46XX. Their initial clock frequency is 2.9 GHz, and the maximum is 3.7 GHz. Higher performance compared to the Celeron series CPU is provided by an increased clock frequency, increased L3 cache up to 3 MB and support for HT technology.

The presence of the latter allows these chips to process software in 4 threads. Core i3 chips are designated 71XX and 73XX. The difference from the younger family in this case lies in the amount of level 3 cache memory, which is 4 MB.

high performance chips

The high-performance Intel processor core consists of four physical code processing units. The i5 chips and, of course, the i7 chips belong to this CPU family. In the first case, semiconductor solutions are marked 7400, 7500 and 7600. The cache at the third level is 6 MB. TurboBust support is also implemented, due to which the chip frequency is dynamically adjusted. The difference between i7 and i5 is the increased cache at the third level up to 8 MB and support for HT. That is, i7 is able to work with program code in 8 threads. As a result, the latest CPU family has a 15 percent performance increase in benchmarks.
