Intel Core i5 processors for the LGA1151 platform. Intel Core i5 processors for platforms LGA1150 and LGA1151 Socket 1151 Processors I7

An old tradition was acquainted with the possibilities of any new platform on the example of the top processors of the K-sedition, and there was no exception with the LGA1151. Core i5-6600K and I7-6700K are already tested in a variety of "poses" by the majority of publications, including. Actually, the Intel policy to promote new solutions has it precisely to such development: firstly, it is to-modify processors that apply among the browsers, and secondly, "ordinary" models are also issued with some delay relative to the "tops" of families. If you go down below the Core i5 in the "table of ranks", then there sometimes should pass for several months to collect the entire product range - for example, Celeron under the LGA1151 will have to wait until the new year. And sometimes not all possible modifications of processors appear on the market - so, Broadwell desktop models are practically no. Dual-core - no, although in the mobile segment it is from them all last fall and began.

But Skylake is designed for massive presence on the market, it is not limited only to part of the segments, like Broadwell (by the way, this happens far from the first time - simply and Ivy Bridge, and Haswell were also massive, so many began to forget the times of Sandy Bridge and earlier microarchitectures). With regard to desktop systems, this means that slowly but steadily the LGA1150 platform will be supplemented by the LGA1151 platform. This does not mean, of course, the components of the first platform will instantly disappear from retail chains, however ... It is enough to look at the commodity residues of the LGA1155, which only two and a half years ago was the main: system fee at least an average level (not to mention High) today you can purchase except that in the secondary market, and there is only a wide selection of processors only there. Accordingly, in order not to be in a couple of years in a similar situation, if necessary, repair and / or modernization, it makes sense now, other things being equal, it is equal to acquire a newer decision. The only thing that can prevent this is the presence of a large amount of DDR3 memory (if necessary, this is quite possible with the LGA1156 or an older platform, but, as we have already found out, the desire to use DDR3 in the new platform does not lead, but Suitable boards are on sale. Another question is that with time DDR3 risks repeat the DDR2 fate, which is on sale, but it is now twice as expensive than DDR3 / DDR4, so in order not to get to a dead end (again - if necessary, repair or modernization), better if necessary With the "old" memory still not to contact.

In general, the time passes when the LGA1151 was just a hot novelty and the subject for theoretical discussions - the usual labor weekdays of the buyer begin. Accordingly, it comes time to test the usual mass models of processors: after all, the segment of processors with CRP above $ 200 accounts for literally 3% of sales, and it includes both all Core i7 and older Core i5. However, the older Core I5 \u200b\u200bfall into it the most edge, so also interesting - especially the Core i5-6600, from the point of view of the buyer who does not plan to accelerate anything, almost identical I5-6600K for the main characteristics (which is not at all like the situation in the top segment where i7-6700 and i7-6700k simply do not intersect in clock frequencies). We have already been tested the most affordable quad-core processor, but there are also "intermediate" i5-6500. In general, it is time to learn all the family (so far without models with TDP 35 W) than we today and we will deal with.

So, at the moment, Intel offers customers of seven Core i5 models under LGA1151, and all of them are quad-core processors, even in the T-family of dual-core no longer - for the first time they remained only among laptop processors, and there and there are for the first time two quad-core Core i5 . In principle, it is not surprising - as we see, and the heat pump of "ordinary" processors is reduced to 65 W, which was once a standard only for dual-core processors, and then not everyone was fitted. Above such a "revolution", the company began to work at the time of Ivy Bridge, but then it turned out not very, and in Haswell at all I had to "retreat" to the usual position. Now the process ended: only "overclocker" models live above 65 W.

What else is interesting? Fighting frequencies are funny: 6400 and 6500 distinguishes as much as 500 MHz, and 6500 and 6600 are only 100. At the same time, the maximum frequency in TURBO Boost mode is a flat line with a step of 300 MHz, which is perhaps more important because at this frequency some The kernels sometimes work, but on the starting - never (with Turbo Boost enabled, of course). Most likely, in practice, the maximum frequency will be evenly achieved or not achieved by everyone, so the processors will be lined up in a flat lineup of performance. But we are just today and check.

Who to compare with? First, we need younger and eldest Haswell. The youngest (I5-4430) for sale for a long time is not visible for a long time, so there is no longer testing it, but 4460 is a very popular model, since it is cheap (and for the year from the moment of its appearance this quality began to be valued much more than before ). Well, let's take the eldest Core i5-4690k, which we, by the way, even with 6600K compared only in a pair with a discrete video card, and now it's time to evaluate them in more often in practice conditions. However, specifically for the K-family, maybe not more often, but 4690k has a complete analogue without unlocked multipliers. Analogue is completely complete: with the same frequencies and even the TDP of the same level (the difference is only 4 W). From the point of view of the search for Holy Grail, such as studying "pure progress", it would be worthy of, of course, test the S-modifications of processors, but from a practical point of view it is not interesting. The buyer is important what you can just buy (with the same costs), and the heat pump in the usual modular desktop, at least the MINI-ITX format has no significant value. In Intel considered it possible to make it regularly tougher? So, if it affects productivity, the company itself is to blame :)

In principle, when looking from the buyer of these two processors is enough. Why not require Core i5-5675c? This is already well-studied model, the strengths and weaknesses of which are well known: the processor with the most powerful in its class integrated graphics, but more expensive than any secret Haswell and Skylake, obviously is a niche solution: it only needs a "hunting" for a powerful GPU . If there is such a need, then the alternatives have no i5-5675c, but if it is not (and there is, for example, the desire to save, or is planned to use a discrete video card at least in the future), then I5-5675C is not needed. In any case, the direct competitor of Core i5 processors under LGA1151 is not.

But Core i5-3570, like some other senior models under LGA1155, is. Of course, in case such a system already has and works, the issue of competition is deprived of meaning: as we have repeatedly wrote, upgrading the working system with the processor of this class on LGA1150 or LGA1151 with a similar thing - there is no point. Yes, weak graphics, but this problem is easier to solve the discrete. But if "at hand" has a computer with a junior processor for LGA1155, which for one or another reasons "is not enough", then the question arises: to change the processor only or go to a new platform? A particularly attractive second option begins to look, if "not enough" is not only a processor. It is clear that "complete modernization" is conjugate with great inconvenience, and it will be tritely more expensive, but suddenly this option will be more attractive from the point of view of performance? Especially since the old (and slow) processor is already difficult to sell separately, but along with the motherboard and memory it is simpler: they will buy them, who else has not been. In general, since we have the opportunity to compare new Core i5 (including younger) with the old, but one of the best in your class - we will do it.

As for other testing conditions, they were equal, but not the same: the frequency of operational memory was maximum supported by specifications. But its volume (8 GB) and the system drive (TOSHIBA ThnSnH256GMCT with a capacity of 256 GB) were the same for all subjects.

Testing technique

For performance evaluation, we used our performance measurement methodology using benchmarks and IXBT Game Benchmark 2015. All test results in the first benchmark We were normalized regarding the results of the reference system, which this year will be the same for laptops, and for all other computers, which is designed to facilitate readers a difficult comparison and choice work:

iXBT Application Benchmark 2015

As it has already been said more than once, this group of applications is highly dependent on the GPU, so that only HD Graphics 2500 Core i5 is a clear outsider: 6 EU Gen7 is very small. Alas, but in those days, the "full-fledged" video frame was guaranteed only laptop models, and in the desktop segment - all Core i7, but only a few models of other families. There is no such problem in Haswell, since simplified GPUs remained only in Celeron and Pentium with all the resulting. Skylake is even better, but not much, although the number sometimes already goes into quality - so the "middle pepper" i5-6500 already overtakes the top i5-4690k. But it concerns this not only GPU, by the way. As we already know, installing a discrete video card based on the Radeon R7 260x to the system on Core i5-3570 speeds up the work almost one and a half times, but it only ultimately catch up with an I5-4690K with an integrated video. And 4690k with the same R7 260X in turn becomes faster than i5-6500, but still lags behind I5-6600. So an approach: " what is your integral me? I will buy a quick discrete and overtaking»Well works except in toys :)

What else is interesting, the processors under the LGA1151 lined up in a smooth line, despite the "insane jumps" of the starting frequency - as we warned, it does not matter. A 6600 is almost equal to 6600K. In the future, it will repeat more than once, so we will already do without comment.

As you can see, even now, when processing video, it is not always possible to extract from OpenCL such a significant benefit, as on the first diagram (however, work on the new version of the test method has shown that the software update and in this group allows you to change a bit, but about it It is too early to talk in detail), so sometimes the video card can be neglected. But it is not the only advantage of Skylake above Haswell, so here already from 4690k almost on the equal "comes" and 6500.

It is noteworthy that, despite several different "preferences" of the programs included in this group, the result turns out to be similar to those obtained in the previous one. And from the repeatability it follows that it is unlikely to be something special :)

But not necessarily - as we have already written more than once, Adobe regularly releases new versions of this program, but the approach to its optimization does not change for five years for a minimum. Accordingly, everything that needs here is one or two high-frequency kernels and nothing else. From this point of view, new processors are not better than old processors, so the productivity is concerned. We also note that this is one of the few cases when the performance of 6600 and 6600K differs noticeably. The reason is simple - with uniform loading there is no difference, the clock frequency of the cores used as the "phenomenon are over" or achieved by Turbo Boost, but when the load "jumps", an economical processor with a long frequency range sometimes to increase the frequency simply "does not have time." From the point of view of energy saving, this approach is useful - once it was possible to perform some kind of work quickly even without increasing the frequency and supply voltage, this is good. But on the performance, as we see, it affects not the best way.

What Audtion Despite the regular (before) optimization behaves sometimes very similar to Illustrator, we also noted more than once. In this case, we have an intermediate between "good" and "bad": 6600 and 6600K here are approximately equal, but 4690k is still lagging behind them. No, in general, "convincing superiority" of a new family.

The recognition of the text is obviously the case when even if you wish, do not "match." Except that the multithreading can be disposed of more fully, but it does not matter when comparing the processors of one class, it does not have (they are all four cores four), and the graphics core if it is put on the service to people, it is clearly not now. We are instead of 4690k 4690s (which on TDP is just much more like new Core i5) - it could get better. But since Intel believes that all processors can be limited to 65 W, it means that newcomers have to act in inconvenient conditions without any discount on the latter.

Although sometimes they need it very much - in this case, it turns out something similar to parity already and "at both ends of the range", which in our opinion is even worse than when older models are not much faster than their predecessors.

And in these cases - it is. Although from the point of view of functionality in terms of supporting various high-speed drives, a new platform is much better than the immediate predecessor, not to mention the LGA1155, it does not always affect the performance accordingly. With the same drive, but different processors it may be different. Actually, why we prefer from these tests not to refuse - in the end, this is what in practice any user of a real computer is facing, where the processor does not work at all in a spherical vacuum.

What come to the end? In principle, Core i5's performance has not changed and does not change for a long time - just all models in the family with each generation begin to work a little faster. Radically increase productivity. It is possible for increasing the clock frequencies, but they have long been kept at the same level (more precisely, in the same range), increasing only in dual-core models or in processors for laptops. However, the development of 14 Nm of the technical process made it possible to increase frequencies and quad-core Core i5 with TDP 65 W, but in parallel they were the main ones in the Intel's assortment, and earlier the "basic" turned out to be completely different heat boosters. Actually, one thing to another and exchanged.

Gaming applications

For obvious reasons, we are limited to computer systems of such a level, we are limited to a minimum quality mode, and not only in the "full" resolution, but also with its decrease to 1366 × 768: despite the obvious progress in the field of integrated graphics, it is not yet able to satisfy the demanding to Quality of the picture of the gamer. And we decided not to check the Core i5-3570 at all on the standard game set: it is obvious that those owners who use the integrated video card, the games are not interested in the word at all. It is enough to remember that the Pentium G2130 turned out to be unable to cope with any game from our set, except without WOT, but its GPU is exactly equal to the HDG 2500. Yes, and the best in Ivy Bridge HDG 4000, too, not enough stars from the sky, so And you can no longer remember about it, not to mention the younger IGP models in processors for this platform platform. Here are newer something can. So let's see what.

As you can see, they begin somewhere where Haswell ends. Differences, however, are mostly quantitative, but they are within the line: 4460 and 4690k can be considered even the same, but in the 6x00 runtime clock frequencies differ already by 200 MHz with a larger number of EU, which together with different heat pumps and Different performance of the processor part already leads to the apparent effect.

WOT is undemanding to the chart so much that here in practice permission can not be reduced, but to play in full, so this is this mode. In which the i5-6400 is already faster than any processors under the LGA1150, and the 6600K shows the same frame rate as 4690K in low resolution.

In Grid2, again, the main "breakthrough" in FHD. Due to not only a change in quantitative characteristics, but also internal changes in the graphics core (formally it is one and a half generation, while with the Ivy Bridge to Haswell changed only half of it), but the main result - one and a half - twice, which will already clearly abandon From the minimum quality settings and improve the picture.

In principle, Core i5 for the LGA1150 has already been minimally suitable for this game (albeit only in low resolution), but on the background of LGA1151 this result is somehow lost: even I5-6400 at least a little, but faster, and senior models are already unconditionally Suitable.

The older game of the series is more demanding on the performance of the processor part, which in conditions of a limited thermal package affects a negative way. However, with the exception of I5-6400, we see the results of the same level with low resolution and greater performance in FHD. It is a pity that there is still insufficient for the game, although ... although it is possible in practice and permission to intermediate choose, for example, so that the improvements in the graphic part are not at least not useless.

Returning to "good" cases. Without quality changes (for HD, there was enough, in FHD and now there is little), but with pleasant quantitative.

In FHD, performance is still too low, but in HD-resolution, gradually approach the "playability" border. At least approaching - on the LGA1150 before it was too far. Unless, of course, consider solely Haswell - I5-5675C, for example, already enough for somehow play, but this is a special story.

Quad-core processors and previously coped with this game in full resolution, but completely without productivity. Now he began to appear. What is funny, the frequency of frames in the case of senior models is almost the same as the AMD A8 processors provide. It is clear that they are cheaper, but also performance in general-purpose programs are also different. But such an eternal advantage of AMD, like higher game performance, begins to gradually dissolve, for which processors with GT3E are not always required.

However, it's not everywhere everywhere it turns out so well, but in general, there is a general productivity increase. Of course, it's not that someone from the computer users could encourage on the old platform to the upgrade - it's better to buy a discrete video card, even inexpensive: it's much more benefit and less than the right. However, the computer's buyer on a new processor for the same money will receive a little more than a year ago.

TOTAL

The state of affairs in the segment of processors for desktop computers has long been depressing enthusiasts. Honestly, and we are to some extent too: the easiest way to write about radical improvements - for example, about the appearance of Core 2 in 2006 or Sandy Bridge in 2011. Then everything was simple and clear: the novelties are definitely better than the predecessors in all respects and in all areas of application. However, it is obvious that these "revolutions" were not so much nascent in the Sector of the Desktop "Persons", as they were a reflection of the processes occurring in the mobile computers market (Core 2 in general was the heir to laptop Core Duo). But then practical benefits from new approaches and technologies and all other, and now changes are clearly not to improve the service of lovers large dusty boxes. Rather, even on the contrary: reduction of cooling requirements is a clear step towards manufacturers of compact systems, but it is no less clearly affected by potential performance. However, it is easy to see that the increase in the performance of the processor cores has long been stopped long ago, the increase in their number - all the more, and what is really becoming more powerful and more powerful (i.e. processor graphic), a lover is not needed to play on a large desktop computer.

In general, it can be stated that the new platform is the same as old but more than the best. A little more productive, a little functional, but does not differ in principle. On the other hand, this is not required: so far new needs will appear in the mass segment (such as there were multimedia technologies or 3D games in the year before last, for example), no significant increase in computing capacities is needed. In principle, everyone who wanted to buy a desktop computer has already done. And if it occurs sometimes to change (due to failure, for example), it is quite suitable as it was. So far it turns out that the new computer will be at least a bit, but better than the old one. But only a little. Times, when in three or five years in the market could be changed, everything was left only in oral legends (however, if it's good to look at the history, they never happened).

Testing modern Core i3 line processors, we noted that the level of performance demonstrated by representatives of this family has changed markedly largely due to the fact that the manufacturer has ceased to "clamp" to the clock frequencies too much. The similar state of affairs was noted in the top segment, where two vertices are clearly distinguished in the form of "old" i7-4790k and "new" i7-6700k, and in their case, the clock frequencies were "allocated abroad" 4 GHz, which in general for processors Intel is not typical. So much that since the release of 4790K "Overclocker" Core i7 simply stopped intersecting with the "ordinary" family, which made them more interesting and for those users who accelerate is not interested. What is the case in the Core i5 segment?

In principle, for many buyers, these processors are maximum interest. The reasons for which simple - the main sales on the market fall on a segment of $ 80- $ 200, i.e. any Core i7, for example, is already in any performance processors not for all To the same extent as Celeron or younger Pentium. Core i3 is actively promoted, which are a mid-level solutions (good and the price corresponds to), and Core i5 is a curious compromise between the desire to get a quad-core processor and reluctance to pay too much for it. As we have already seen on average, the younger modern Core i5 in terms of performance with older Core i3 are already intersecting, but it is an average: in some tasks, "they are still faster, despite the substantial lag on the clock frequency. However, it is possible to compensate for this without such significant costs: in principle, the price difference between 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 stretch to "at least some kind of" Core i5, then there are those who prefer the older model of this family. Especially when purchasing a new computer, the costs of which significantly exceed the cost of the processor actually, making the choice of a powerful model simpler psychologically. More difficult to modernize - in fact, in this case, it is possible to calculate only on the productivity increase due to the "intensive methods" when moving from generation to generation, since the clock frequencies here practically did not grow. It is enough to compare the same 6600K with a 2500K five-year old statute - some 200 MHz at both ends of the range when Core i3 or "K" -Modification of Core I7 scored to 500.

In general, in this segment everything should be enough "smoothly and calmly." Nevertheless, how interesting is. So today we just decided to explore the older models of two and a half Linek Core I5, initially giving themselves a report that no "miracles" cannot be detected.

Why are we talking about two and a half rules? Because the desktop Broadwell is not fully drawn - "desktop" models here are exactly two: one Core i5 and one Core i7. The latter, as we have already convinced, could be the "flagship of the LGA1150", if ... if it worked on all boards, if just a couple of months, a new platform did not appear if the "steroid was not published »4790K. However, here's the Core i5-5675c such a problem is deprived - as we have noted above, and 4690k, and 6600k so much from it in frequency does not come off. At the same time, the presence of a fourth-level cache sometimes and I7-5775C compensated for its backlog from 4790K (very noticeable), so that the "younger fellow" may turn out to be the second, and then first in its segment. Even in general-purpose applications - if you leave for video cards, there are still no similar models for LGA1151 at the moment. It is clear that, acquiring the computer mainly for games, you need to buy a discrete video card, but on the processor, if necessary, you can (and, in this case, you need!) Save, but it happens when you just need something compact, not too voracious, but Capable at least without questions relatively successfully cope with at least five-year-old hits. What makes this processor is still relevant.

Unlike 4690K, although the latter can come in handy by the one who already has a system on the LGA1150, but the performance ceased to grasp: for example, the solid tasks changed a little. In this case, the replacement is only a processor, naturally, easier and cheaper than the transition to a new platform. And in some markets of developed countries, "old" can already be given to essential discounts. This is at least two reasons why this processor is still replicated from accounts (especially - it is a slightly cheaper "twin brother" with blocked multipliers) is not worth it. In the rest - it is better to pay attention to the new platform. Accordingly, the processors for it will be two - the youngest Core i5-6400, the benefit of it we are already familiar well and the fastest I5-6600K currently.

Testing technique

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

• Methods for measuring power consumption when testing processors
• Method of monitoring power, temperature and processor loading during testing

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

iXBT Application Benchmark 2016

This is immediately the situation, the possibility of which was voiced a little higher - the fastest Core I5 \u200b\u200bturned out to be 5675s. However, it is impossible to say that its advantage is so great, first. Secondly, it will be less when using a discrete video card - these GPU programs sometimes use thin poorly.

As well as a group of applications for working with photos. However, it has a complete Skylake celebration - not even because the 6600k turned out to be the fastest, and because the most slow in the Core i5-6400 family came close to 4690k, which was officially the fastest Core i5 just a year ago. In general, we are increasingly strengthened by the suspicion that the specifics of recent years (and the main goals in the development of new microarchitets) are able to bring the main binifications to customers of the mid-level desktop processors. Or budget. But the top segment is updated only to the insight-since, and the older Core i5 models are also touched.

We have already noted some "dislike" of the previous version to the Broadwell processors with the fourth-level cache - as we see nothing has changed. But the models under the LGA1151, on the contrary, clearly accelerated. However, not only in this program, so it may be that the errors and other "little things of life affected the system for correcting mistakes.

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

As well as in this case. Actually, taking into account the similarity of processors on the organization, there is nothing surprising and in the fact that at different code they behave about the same. It differs significantly from other I5-5675C, but two ways: L4 and GPU pull it forward, where possible, but lower, rather than two other frequency tops - back and always. The end result in its case may vary within the range of 4690k- 6600K. And in special situations - and go for it.

For example, as here. But this is just an ideal option for a more powerful hierarchically memory system - it is clear that L4 is faster than RAM. And if you also remember it huge (according to the standards of caches), the capacity, then the result is no surprising.

But file operations are made approximately the same, since directly from the processors of this class is almost independent.

As we have already written, in Broadwell optimizations it was enough to and with a smaller clock frequency to overtake Haswell, and the sensibility of the program to delays and the bandwidth of the memory system is available. In general, the eldest Core i7-4790k and 6700K strongly "saved" a serious advantage in the clock frequency, however, as mentioned above, there is no such in the Core I5 \u200b\u200bfamily. With all the consequences arising from here.

In the end, we come to the fact that even in general-purpose applications, 5675s still looks good - 4690k he overtakes much more thanks, rather than behind 6600k. Unfortunately, this line of noticeable spread did not receive, and we have not seen its further development, although it would be interesting. As a result, we come to a slightly strange state of affairs. 4690k In general, it is clear why you need - it is somewhat cheaper than the remaining subjects, and well suited for the modernization of almost any system with LGA1150 (little Li-bought two years ago Core i3 start "miss" after replacing the camcorder, for example), so now Well for sale. Especially considering that calmly and overclocking (still popular in certain circles) is well. Core i5-5675c same in any motherboard will not deliver, and it costs as a senior (in class) solution for a newer and promising "platform. As a result, you can buy, of course, but measuring three times. However, the strongest thing for all three today's heroes "beats" is not this, and the prices for junior ruler processors for LGA1151 - 6400 and neighboring with them. As you can see, they are not so slower, all as "promising" and noticeably cheaper. As a result, it turns out that older Core i5 can come in handy only overclocking lovers, since their clock frequencies have not grown for a very long time. Unlike Core i7, where for two years the top model has been really topped in any scenario of use.

Energy consumption and energy efficiency

Another strong place of younger Core I5 \u200b\u200bis extremely temperate appetite. Inherent in the elders, despite the formally high official heat pump, but less pronounced. The youngest is already easily limited by the amounts of energy, not so long ago only with dual-core models (and even earlier - only some such).

Accordingly, if the Core i5-6400 is removed from the diagram - we see a beautiful and even ladder with approximately equal steps corresponding to the change of generations. For i5-5675, even winning, but by changing the technical process. However, it is worth considering not only the elders, but also the younger processors for LGA1151, as suddenly it turns out that without changing the norms of production, it is possible to achieve very good results, if not too chasing performance. Actually, that the older models of Broadwell did a niche solution literally 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, such a development of events gives reimers not only for joy, since so far for LGA1151 there are only processors only with GPU GT2. In practice, as we see, this is the same level of productivity as "socket" Haswell, but not in any comparison with GT3E Broadwell (we decided to do today without detailed results, because they were observed repeatedly, and in the table they There is also there). However, if you acquire a computer, focusing on the game application, it does not matter much - it's still without a decent discrete video card can not do. It is better to save just on the processor - a pair of Core i3-6100 C, for example, Radeon R7 370 will distribute any modern integrated schedule to smithereens and in half. But if the system compactness priority, and games - intearca-since, there would be just such a decision and came in handy. But it exists so far only for the platform leaving from the market.

TOTAL

So what do you come in the end? As we have already established, during their existence in the "historical period" processors of the Pentium and Core i3 families, productivity increased significantly due to not only intensive methods, but also a banal growth of clock frequencies. In principle, they were ready for this before, however, the manufacturer specifically limited these models in order to avoid unnecessary competition with more expensive Core I5. Such an approach was applied in relation to Core I7, only there the clock frequencies not all models have increased - just in 2014, the "overclocker" series, "overlapping" for a mark of 4 GHz, was separated from the main family. But Core i5 actually remained at the mark, achieved another five years ago with all the consequences from here. Of course, the performance of representatives of this family grew, but much less pace - only due to architectural changes. Or thanks to the introduction of another level of cache memory, which is not yet implemented within the LGA1151. However, the approximate effect of this can be estimated - as we see, not so small.

Effect of RAM on system performance

Introduction

It is difficult to argue that the growing dollar rate was seriously affected by buyers of computer components, because in just a year of the "hardware" rose in price by 30-60%. What makes manufacturers attached, what steps are made to hold positions in the market? Who reacted faster to the unfavorable situation suddenly? Answer these questions will be easier if you look at the situation as a whole.

The trios of the most massive suppliers of motherboards are ASRock, Asus and MSI, the market share of which almost reaches 70%. And the most tasty part of the cake is the segment of solutions for the Intel Skylake CPU - thanks to the fresh processors, the probability of seduce buyers is growing. But if earlier users forgot the poles of Intel and during the transition from one type of CPU to another, the platforms changed, now the people have become leaning.

Of course, technology does not stand still, but this time instead of one plum step we received only his likeness. For example, try to find five differences between the system boards 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 you could collect a good computer. Why then take an expensive motherboard, if you can do the version more modest? Perhaps your weight word will say overclocking? And here Intel tried to overlap the oxygen as much as possible to buyers.

Manufacturers, seeing a decline in consumer demand, began to introduce new opportunities, including undocumented. But after that Intel, the principles of segmentation of their products in Absolut elevated - if desired, it is now unable to disperse only the CPU, also the motherboard based on Intel Z170 is needed. And there is no doubt that under the onslaught vendor, manufacturers will sooner or later remove the possibility of overclocking processors without the "K" index. Apparently, it is now important not to miss the moment, choose something suitable among hundreds of motherboards and stop updating the BIOS.

The mentioned Trinity also did not sit back and gradually ranked Russian retail more accessible models. And almost all of everyone has already been told earlier in a series of materials, broken through the sets of system logic:

• Budget options on Intel H110;
• Available models and solutions class above on Intel B150;

With Skylake, Kaby Lake cores, and Coffee Lake with 1151 contact. It is not compatible with the previous processor connectors LGA1150, 1155 and earlier sockets both mechanically and electrically. At the time of writing this article, within the framework of the LGA1151 socket, there was a division into early fees with chipsets 100 and 200 Series and on new boards with 300 Series chipsets. The sockets within the data of the platform data are compatible mechanically, that is, you can install any processors with the specified socket, but are not compatible with electrically, because of the boards with old chipsets it is impossible to use COFFEE Lake processors, and you cannot use Skylake and Kaby Lake.

What processors are suitable for installation with LGA1151 socket?

For installation in Socket LGA1151, the Core processors of the sixth, seventh and eighth generations are suitable. For the performance of the sixth and seventh generations processors, the motherboard must be equipped with one of the Intel Z270, Q270, H270, Z170, Q270, H170, B250, B150, H110 chipsets. To support the processors of the eighth generation, the motherboard must be equipped with the Z370 chipset, or chipsets that appear slightly later, for example, H370, Q370 or Z390. To distinguish between the Core processors of different generations, it is enough to look at their marking. The first symbol in digital processor marking indicates a generation, for example, Intel Core i5-8600K refers to the eighth generation. Detailed processor characteristics and comparison them can be found by clicking on the button:

Which of the Skylake processors, Kaby Lake, and Coffee Lake work faster?

In accordance with the release chronology, processor performance increased. A particularly strong performance increase is observed in the processors of the eight-generation Core family, as they have changed the number of nuclei for the first time with the transition to the names of the Core I type I.

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

All processors with the LGA1151 connector support the two-channel memory mode. SKYLAKE supports LV DDR3 with a frequency of up to 1600 MHz and DDR4 with a frequency of up to 2133 MHz. Kaby Lake supports LV DDR3 with a frequency of up to 1600 MHz and DDR4 with a frequency of up to 2400 MHz. Coffee Lake supports only DDR4 with a frequency of up to 2666 MHz.

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

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

What colaers are compatible with LGA1151?

The seating of coolers for LGA1151, LGA1150, LGA1155 and LGA1156 is identical, so the cooler for old processors is compatible with new ones. Considering that TDP processors practically did not change, the transition from the old platform to a new one will not require the replacement of the cooling system.

Hello, technoblog readers. Today I will tell you which processors are suitable under Sotet 1151 (Skylake, Kaby Lake), as well as 1151V2 (Coffee Lake). In this article, we will try to tell about the most powerful, inexpensive and cheap Intel Core, Pentium and Celeron chips.

The list of CPU will be built as a list so that you have a more accurate view of the models presented in the market.

And yes, it is worth making an important refinement: Socket LGA1151 does not imply reverse compatibility with 1150 and does not support Xeon server processors.

Table compatibility table

Socket 1151 from Intel is very cunning in essence, because it has 2 versions: the first supports the chips of the 6th and 7th generations, and the second is only the 8th. With respect to the picture it is much easier to make up, but it's not about him.
Let's see what, as well as I3, I7, Pentium and Celeron are able to work at 1151 Gen 1.
Now consider the line of chips that are suitable for the motherboard with a socket 1151v2.
In 2018, the 9th generation CPU was added to the previous list.

Optimal processor for its value

And now the most interesting part of the comparison. We designated 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 the CPU - we recommend reading this article.
And now we will go through the most vivid representatives of 6.7 and 8th generations:

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

Kaby Lake - Intel Pentium G4620. The so-called "hyperpen" has become cult, among gamers at the time of the exit, since he offered the Intel Core i3-7100 functionality at a significantly lower cost. It is also worth mentioning the vigorous middling I5-7400 and the top version of i7-7700K, in which 4 kernels and 8 data processing threads. Stone and to this day is considered a relevant, powerful and interesting solution for progressive systems, and also supports acceleration up to 5 GHz on the factor.

Coffee. Lake - I5-8400. The appearance of the 8th generation of Intel chips added not only a new socket, but also 2 additional kernels of each line, with the exception of Celeron and Pentium. Have a 6-nuclear processor that can automatically increase the frequency from 2.8 to 4 GHz - a very successful contribution to the future and therefore I bold it recommended it (at the prices of I5 you can navigate this (especially, many of this discounter is well known as reliable and Verified seller)).

Difference between1151 and 1151.v2.

It is not a secret for a long time that the processor connector intended for sets of system logic of the 100th and 200th series is absolutely not compatible with the 300th. And the point is not even that Intel wants to earn more money. The introduction of additional cores forced engineers in the root to recycled Coffee Lake processors to ensure the stable operation of chips, even under extremal acceleration.
Key changes affected VCC and VSS (Earth) contact sites. At the same time, the number of previously reserved RSVD contacts has decreased. Thus, the situation is as follows:

	Skylake / Kaby Lake	Coffee Lake
VCC.	110	128
VSS.	364	378
RSVD.	46	25

As you can see, "make friends" old chips with new motherboards are physically impossible, like a chinese plug into a European outlet. Yes, there are enthusiasts that managed to start the Kaby Lake on the Z370 by modifying the BIOS, however, the lion's share of functions in this case worked unstable, and the rest was completely absent.

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

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