Socket 1151 i7 processors. Intel Core i5 processors for LGA1150 and LGA1151 platforms. Which processors are suitable for installation with the LGA1151 socket

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 to avoid making a mistake when buying a processor.

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

• Skylake is the sixth generation of processor microarchitecture Intel Core. According to the Tick-Tock strategy followed by Intel company, this architecture has received significant changes and improvements, but without switching to a new technical process. Like the Broadwell architecture, the Skylake architecture uses a 14 nm process technology. The first Skylake chips went on sale in August 2015. The main features of the Skylake architecture are: support for Thunderbolt 3.0, support for 512-bit vector instructions AVX 3.2, support for SATA Express, new tire DMI 3.0, built-in image processor.
• Kaby Lake is the seventh generation of 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 at the beginning of 2017. The main features of the Kaby Lake architecture are: USB support 3.1, support for Intel Optane memory, 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 Intel Core processor microarchitecture. According to the Tick-Tock strategy, the Coffee Lake architecture is an improved version of Kaby Lake with 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 with speeds up to 10 Gbps, support for Intel Wireless-AC, support for the new generation of Intel Optane.

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

It should also be recalled that at the time of writing, Socket LGA 1151 is the current platform and new processors may still be released on 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 purchasing a processor, you should always look at the list of supported processors on the motherboard manufacturer’s website.

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 on the “Mainboard” tab.

After this, you need to study the information on the motherboard manufacturer’s website. There should be a list of supported processors. Typically this list can be found in the "Support" or "Support" section.

The processors from this list are 100 percent supported by the motherboard and can be purchased with confidence.

Which processors are suitable for socket 1151 and 1151v2

Hello, technoblog 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 inexpensive Intel Core, Pentium and Celeron chips.

The list of CPUs will be arranged in a list so that you have a more accurate idea of ​​the models on the market.

And yes, it’s worth making an important clarification: socket LGA1151 does not imply backward compatibility with 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 the 8th. Regarding the AM3 socket, the picture is much simpler, but this is not what we are talking about.
Let's see which i5 processors are different generations, as well as i3, i7, Pentium and Celeron are capable of running the 1151 Gen 1.
Now let's look at the line of chips that will fit a motherboard with socket 1151v2.

Optimal processor for its price

Now comes the most interesting part of the comparison. We have indicated which processor is suitable for a specific socket. Now it remains to decide on the model of the chip itself. If you want to learn more about CPUs, we recommend reading this article.
Now let’s look at 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 thermal package of 35 W.

Kaby Lake Intel Pentium G4620. The so-called “Hyperpen” became a cult among gamers at the time of its 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-end version i7-7700k, which has 4 cores and 8 data processing threads. The stone is still considered relevant, powerful and interesting solution for progressive systems, and also supports overclocking up to 5 GHz multiplier.

Coffee Lake – i5-8400. The emergence of the 8th generation of Intel chips added not only a new socket, but also 2 additional cores for 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 confidently recommend it to you (and at the same time there is an interesting offer for you - Intel Core i5 8400 + Free shipping).

Differences between 1151 and 1151v2

It has long been no secret that the processor socket designed for system logic sets 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 rework the power supply circuit of Coffee Lake processors to ensure stable operation of the chips, even under extreme overclocking.
Key changes affected the VCC (power) and VSS (ground) pads. At the same time, the number of previously reserved RSVD contacts has decreased slightly. So 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 were unstable, and the rest were completely missing.

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

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

Sincerely, Andrey Andreev

What are the prospects for the socket now?

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

Three-channel DDR3 memory will allow the speed to approach the initial two-channel DDR4. At the same time, DDR3 ECC modules are now the most affordable.

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

A short summary

Apparently, this is a simplified version of the 2011 socket.

Advantages:

• Cheap processors and RAM
• Three-channel memory
• A budget gaming build will be cheaper than on LGA2011

Flaws:

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

Intel processors. Performance rating for the LGA1151 platform

This article will review the most current Intel processors. The rating of their performance given below will indicate whether one or another model belongs to a certain niche of the semiconductor chip market.

Celerons are Intel's least powerful desktop processors. Their performance rating indicates that they are ideal only for use in office computing systems that are capable of performing only the most simple tasks: text and spreadsheet programs, browsing websites, playing multimedia and reading books electronically.

This family of chips includes 3 models: G3930T, G3930 and G3950. The key difference between them is the clock speed. The younger model operates at 2.7 GHz, the middle one at 2.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 2 MB third-level cache. The price for the younger models is 42 dollars, and for the older one - 52.

Average level

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 ensured by an increased clock frequency, an increased third-level cache to 3 MB and support for NT 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 is the volume of level 3 cache, which is 4MB.

High performance chips

The high-performance Intel processor core consists of four physical code processing units. This CPU family includes i5 and, of course, i7 chips. In the first case, semiconductor solutions are labeled 7400, 7500 and 7600. Their 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 to 8 MB and NT support. That is, i7 is capable of working with program code in 8 threads. As a result, the latest CPU family has a 15 percent increase in performance in tests.

Today we will understand the differences between Intel 1151 chipsets and the differences between motherboards based on H110, B150, B250, H170, H270, Z170, Z270 chips. There are many different misconceptions: some “overclock” processors on motherboards with the H110 chipset, others are “convinced” that games only require a “game board” Z170, Z270.

In 2018, the article “What are the differences between Intel chipsets” is more relevant 1151v2“You can read it.

Let's look at what the difference really is and what motherboard suitable for your needs.

The first point should be noted that there is no fundamental difference between the 100 and 200 series of chips. Overall, the 200 series received minor feature improvements over the 100 series.

The hundredth series of motherboards was made before the release of the seventh generation of Intel processors - Kaby Lake and, accordingly, their “old” BIOS is designed only for Skylake (6th generation Intel processors). However, if you buy a new motherboard of the 100th series, then the BIOS will most likely be flashed at the manufacturing plant by the manufacturer itself (usually indicated on the packaging), which means it will support processors of both generations. The 200th series already supports both Kaby Lake and Skylake out of the box.

All the features and functions of the 100 series have been carried over to the 200 with some additions. For example, running an SSD with Optane cache support will strictly require a 200-series chipset and Kaby Lake processors of at least i3. The most optimal PC in 2018 - read.

Features of motherboards based on the H110 chipset

If you decide to build a system on a limited budget, then the H110 chipset is your choice.

H series chipsets have traditionally served as cut down versions of the Z series due to smaller HSIO slots and lack of overclocking support.

1. No processor overclocking (with the exception of very rare models which are quite difficult to get in Russia)
2. The power system is usually 5-7 phases (for a motherboard not intended for overclocking it is quite enough)
3. Two connectors for RAM
4. One video card (no Crossfire/SLI capability)
5. Maximum RAM frequency – 2133MHZ
6. Up to 4 USB, 4SATA ​​3x4PIN FAN
7. Missing technology: INTEL SMART RESPONSE RAPID STORAGE

All these restrictions lead to the fact that this motherboard is very cheap. It is perfect for budget builds, but with the ability to install the latest generation processors. Based on this chipset you can build gaming computer entry-intermediate level. The average price of motherboards based on the H110 chipset is 2.5-3.5 thousand rubles.

Features of motherboards based on B150/B250 chipsets

Motherboards based on B150/B250 chips have, perhaps, the best price/quality ratio (if overclocking is not important to you). Ideal for an average system.

The price for boards on B150/B250 chips is from 4 thousand. The only drawback is that there is no support for a raid array (combining two (or more) physical disks into one “physical” disk).

1. No CPU overclocking
2. No RAM overclocking
3. Maximum RAM frequency - 2133MHZ (B250 - 2400MHZ)
4. Up to 12 USB, 6 SATA 3-5 X4PIN FAN, up to 2 M2 connectors? USB 3.1 support
5. Technology support: INTEL SMALL BUSINESS ADVANTAGE

Features of motherboards based on H170/H270 chipsets

Solutions based on H170 are a compromise between the B150/B250 and Z170/Z270 chips. The user gets even more features: support for a raid array, more ports, but still cannot use this motherboard for overclocking.

1. No CPU overclocking
2. No RAM overclocking
3. Power system 6-10 phases (usually)
4. Up to 4 slots for RAM
5. Yes Crossfire X16X4, No SLI support
6. Maximum RAM frequency - 2133MHZ (H250 - 2400MHZ)
7. Up to 14 USB, 6 SATA 3-7 X4PIN FAN, up to 2 M2 connectors? USB 3.1 support

Features of motherboards based on Z170/Z270 chipsets

Motherboards based on the Z170/Z270 chipset offer overclocking capabilities. There are useful features for enthusiasts, such as: power buttons directly on the motherboard itself, post-code indicators, additional fan connectors, BIOS reset and switch buttons. All this greatly simplifies the life of enthusiasts (people who overclock).

In addition to the fact that you can overclock a processor on motherboards with Z170/Z270 chips, they also allow you to use faster sets of random access memory (RAM) and overclock them.

1. Supports CPU overclocking
2. Supports RAM overclocking
3. Power system 7-13 phases (usually)
4. Up to 4 slots for RAM
5. CROSSFIRE X8X8/X8X4X4/X8X8X4, SLI X8X8 possible
6. Maximum RAM frequency - 4500MHZ (B250 - 2400MHZ)
7. Up to 14 USB, 6 SATA 5-7 X4PIN FAN, up to 3 M2 connectors, USB 3.1 support
8. Technology support: INTEL SMALL RESPONSE TECHNOLOGY, INTEL RAPID STORAGE

By the way, we did not touch upon motherboards on the chipset with the “Q” index. These motherboards are used primarily for business and very rarely in home assemblies. In essence, the Q170 chip is an analogue of the H170, but with corporate features. By the way, you might be interested in the article “The best gaming processor. Intel Review Core i7-8700K", you can read it.

With Skylake, Kaby Lake, and Coffee Lake cores having 1151 pins. Not compatible with previous LGA1150, 1155 and earlier processor sockets, either mechanically or electrically. At the time of writing this article, within the LGA1151 socket there was a division into early boards with 100 and 200 series chipsets and new boards with 300 Series chipsets. The sockets within these platforms are mechanically compatible, that is, any processors with the specified socket can be installed in them, but are not electrically compatible, which is why it is impossible to use Coffee Lake processors on boards with old chipsets, and Skylake and Kaby Lake cannot be used on new ones.

Pin locations in the old (left) and new (right) LGA1151 sockets

Which processors are suitable for installation with the LGA1151 socket?

Core processors of the sixth, seventh and eighth generations are suitable for installation in the LGA1151 socket. For processors of the sixth and seventh generations to work, the motherboard must be equipped with one of the Intel Z270, Q270, H270, Z170, Q170, H170, B250, B150, H110 chipsets. To support eighth generation processors, the motherboard must be equipped with the Z370 chipset, or chipsets that will appear a little later, such as the H370, Q370 or Z390. To distinguish between Core processors of different generations, just look at their markings. The first character in the digital marking of processors indicates the generation, for example, the Intel Core i5-8600K belongs to the eighth generation. Detailed characteristics of processors and their comparison can be found by clicking on the button:

Which Skylake, Kaby Lake, and Coffee Lake processors are faster?

In accordance with the release chronology, processor performance increased. A particularly strong increase in performance is observed in the eighth generation Core family of processors, since the number of cores in them has changed for the first time since the transition to names like Core i.

What type of memory does Skylake, Kaby Lake, and Coffee Lake processors support?

All processors with the LGA1151 socket support dual-channel memory mode. Skylake supports LV DDR3 up to 1600 MHz and DDR4 up to 2133 MHz. Kaby Lake supports LV DDR3 up to 1600 MHz and DDR4 up to 2400 MHz. Coffee Lake only supports DDR4 up to 2666 MHz.

How many PCI-E 3.0 lanes does the controller built into Skylake, Kaby Lake, and Coffee Lake processors contain?

All processors with an LGA1151 socket support the same number of PCI-E 3.0 lanes – 16 pcs. Additional lines contain motherboard chipsets, due to which there is a fairly large number of boards that support configurations with multiple video cards.

Which coolers are compatible with LGA1151?

The cooler mountings for LGA1151, LGA1150, LGA1155 and LGA1156 are identical, so coolers for old processors are compatible with new ones. Considering that the TDP of processors has remained virtually unchanged, the transition from the old platform to the new one will not require replacing the cooling system.

Testing modern processors of the Core i3 line, we noted that the level of performance demonstrated by representatives of this family has changed noticeably, largely due to the fact that the manufacturer has stopped “clamping” their clock frequencies too much. A similar state of affairs was noted in the top segment, where two peaks clearly stand out in the form of the “old” i7-4790K and the “new” i7-6700K, fortunately in their case the clock frequencies were “allocated abroad” 4 GHz, which is generally for processors Intel is not typical. So much so that since the release of the 4790K, “overclocker” Core i7s simply no longer overlap with the “regular” family, which made them more interesting for those users who are not interested in overclocking. How is it going in 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 fall in the $80-$200 segment, i.e. any Core i7, for example, these are processors of any version not for all to the same extent as Celeron or younger Pentiums. Core i3, which are mid-level solutions, are actively promoted (fortunately, the price matches), while Core i5 turns 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 already seen, on average, the younger modern Core i5 already overlaps with the older Core i3 in terms of performance, but this is on average: in some tasks that “gravitate towards multi-threading” they are still faster, despite a significant lag in clock frequency. However, this can be compensated for 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 are diligently reaching for “at least some” Core i5, then there will be those who will prefer the older model of this family. Especially when purchasing a new computer entirely, the costs of which significantly exceed the cost of the processor itself, making the choice of a powerful model easier psychologically. It’s more difficult with modernization - in fact, in this case, you can only count on a performance increase due to “intensive methods” when moving from generation to generation, since clock frequencies here practically did not increase. It’s 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 reached up to 500.

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

Why are we talking about two and a half lines? Because desktop Broadwells are not fully functional - there are exactly two “desktop” models here: one Core i5 and one Core i7. The latter, as we have already seen, could have become the “flagship LGA1150” if... If it had worked on all boards, if literally a couple of months later a new platform had not appeared, if a year before it the “steroid » 4790K. However, the Core i5-5675C does not have such a problem - as we noted above, both 4690K and 6600K are not that far behind it in frequency. At the same time, the presence of fourth-level cache memory sometimes compensated for the i7-5775C’s lag behind the 4790K (very noticeable), so the “younger brother” may turn out to be second, or even first, in its segment. Even in general-purpose applications - if you focus on the video core, then similar models for LGA1151 this moment still not at all. It is clear that when purchasing a computer primarily for gaming, you need to buy a discrete video card, but if necessary, you can (and, in this case, need to!) save on the processor, but it happens when you just need something compact, not too power-hungry, but capable of, at least without question, relatively successfully coping with at least hits from five years ago. What makes this processor still relevant today?

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

Testing methodology

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

• Methodology for measuring power consumption when testing processors
• Methodology for monitoring power, temperature and processor load during testing

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

iXBT Application Benchmark 2016

Here we have a situation, the possibility of which was announced a little higher - the fastest Core i5 turned out to be 5675C. However, it cannot be said that his advantage is so great, firstly. Secondly, it will be smaller when using a discrete video card - these GPU programs sometimes, at the very least, use them.

As well as a group of applications for working with photographs. However, it demonstrates the complete triumph of Skylake - not even because the 6600K turned out to be the fastest, but because the slowest Core i5-6400 in the family came 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 ones. But the top segment is updated only to the extent that it is, and the older Core i5 models are also already affected by this.

We have already noted some “dislike” previous version to Broadwell processors with fourth-level cache - as we see, nothing has changed. But models for LGA1151, on the contrary, have clearly accelerated. However, not only in this program, so it may turn out that the error corrections that happened in the field of system software and other “little things in life” also had an impact.

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

The same as in this case. Actually, taking into account the similarity of processors in organization, it is not surprising that they behave approximately the same in different codes. The i5-5675C is significantly different from the others, but in two ways: L4 and GPU pull it forward where possible, but lower frequencies than the other two tops pull it back and always. The final result in his case can vary within the range of 4690K-6600K. And in special situations - and marry him.

For example, like here. But that's just it perfect option for a more powerful hierarchically memory system - it is clear that L4 is faster than RAM. And if we also remember its huge (by cache standards) capacity, then the result is all the more unsurprising.

But file operations are performed approximately the same, since they almost do not directly depend 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 also the program’s susceptibility to delays and bandwidth memory system available. In general, the older Core i7-4790K and 6700K were greatly “saved” by a serious advantage in clock frequency, 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 outperforms the 4690K much more than it lags behind the 6600K. Unfortunately, this line has not received noticeable distribution, and we have not yet seen its further development, although it would be interesting. As a result, we arrive at a slightly strange state of affairs. 4690K in general is clear why it is needed - it is somewhat cheaper than the rest of the tests, and is well suited for upgrading almost any system with LGA1150 (you never know - the Core i3 purchased two years ago began to “not be enough” after replacing the video camera, for example), so now sells well. Especially considering the fact that it is calm and has a good attitude towards overclocking (still popular in certain circles). Core i5-5675C in any system board you can’t install it, and it costs as an older (in class) solution for a newer and “promising” platform. In the end, you can buy it, of course, but after measuring it three times. However, what hits all three of today’s heroes the hardest is not this, but the prices of the low-end processors in the line for LGA1151 - 6400 and those adjacent to them. As you can see, they are not that much slower, they are all just as “promising” and noticeably cheaper. In the end, it turns out that older Core i5s can only be useful to overclocking enthusiasts, since their clock frequencies have not increased for a very long time. Unlike the Core i7, where the top model has been the top model for two years now - truly top-end in any usage scenario.

Energy consumption and energy efficiency

Another strong point of the younger Core i5 is its extremely moderate appetite. It is also present in the elders, despite the formally high official heat package, 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 it’s even winning, but due to a change in the technical process. However, it’s worth considering not only older, but also younger processors for LGA1151, and it suddenly turns out that even without changing production standards you can achieve very good results, if you don’t chase performance too much. Actually, this is what made the older Broadwell models a niche solution literally right away: 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 see, this is the same level of performance as that of the “socket” Haswell, but cannot be compared with the GT3e Broadwell (we decided today to do without detailed results, since we have observed them more than once, and they are also in the table there too). However, if you buy a computer focusing on gaming use, this does not matter much - you still cannot do without a decent discrete video card. It’s better to save on the processor - a pair of Core i3-6100 with, for example, a Radeon R7 370 will blow away any modern integrated graphics to pieces 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 a platform that is leaving the market.

Total

So, what do we end up with? As we have already established, during its existence in “ historical period» processors of the Pentium and Core i3 families have noticeably increased their performance thanks not only to intensive methods, but also to a banal increase in clock frequencies. In principle, they were ready for this before, but 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 Core i5 actually remained at the level reached five years ago with all the ensuing consequences. Of course, the productivity of representatives of this family grew, but at a much slower pace - only thanks to architectural changes. Or thanks to the introduction of another cache memory level, 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.

LGA-1151 is a standardized and still relevant socket designed for installing Intel processors with 6th and 7th generation architectures - Skylake and Kaby Lake. To interact with the 8th generation of processors, an alternative version of the socket is provided - LGA 1151 v2, although similar in design to the “original”, but differing in the approach to the organization of contact pads and power circuits, which ensure stable operation of chipsets installed in the motherboard under extreme load or when using non-standard cooling. The remaining characteristics of the connectors are similar - the same spring-loaded contact for contact with the processor, familiar DMI 3.0 and PCI Express 3.0, identical mounting of tower coolers.

The approach is as follows:

• LGA-1151. Core i7, i5 and i3 processors are supported, as well as the 6th and 7th generation Pentium and Celeron series belonging to Skylake or Kaby Lake.
• LGA-1151 v2. Core i7, i5 and i3 and the Pentium and Celeron series are connected, but already of the 8th generation, which are marked Coffee Lake.

Optimal processor

Among the available variety of processors, identifying specific models is more difficult than it seems at first glance. And the main reason for this is lack of information. What is the money ceiling? Will an upgrade be needed in the future? Do you need a gaming platform or an office one? If you don’t go into details and focus on the only indicator - price/quality, then from Skylake it is worth noting the Intel i5 6400T, from Kaby Lake - the Intel Pentium G4620, and from Coffee Lake - the i5-8400.

The second revision of the LGA 1151 socket appeared at the end of 2017, along with the release of Coffee Lake series processors, which, as Intel developers immediately warned, are electrically incompatible with the “original” (due to changes that affected the number of contact pads responsible for power supply , signal transmission and processing of some processes, installation of old-generation processors on a new one is impossible - however, backward compatibility is not provided).

Hence, in fact, the conclusion - the differences between the versions are reduced to the method of organizing power supply and electrical “recharge”. And, since there was a desire to install Coffee processor Lake, then you will have to look for LGA-1151 v2 motherboards on sale (necessarily with DDR4 support), but if you need Skylake or Kaby Lake, then LGA 1151 with DD3 will do.

Top 10 motherboards with LGA 1151 socket

The choice of motherboard with connectors of the first and second revision directly depends on the number Money and the preferred brand, and additional characteristics, such as a built-in Wi-Fi module or support for two or even four PCI-E x16 slots for installing video cards. And therefore, drawing a parallel between recommendations in a similar vein is more difficult than it seems at first glance - the chances of being reduced to subjective advice rather than straightforward help are too high.

Therefore, even before getting acquainted with the top 10 motherboards, you should look into the nearest online store and, having placed the appropriate tags, start searching (you should immediately indicate the price, select the manufacturer and form factor - for example, ATX or Mini-ATX, and At the same time, decide on the sound circuit or RAM slots).
