Core i5 and i7 processors in LGA1155 design
Finally, the long-awaited moment has come when you can get acquainted with the performance of Intel processors for the new LGA1155 platform! True, just like last year, it fell exactly on holidays, but that’s okay — after recovering from the rest, the more interesting it is to go to the store 🙂 By the way, not only the date makes today’s event related to the announcement of processors based on the Clarkdale core a year ago. The fact is that the story with LGA1156 is essentially repeating itself — the announcement of new processors is stretched over several stages. Today we will learn all the details about the quad-core models of the Sandy Bridge architecture, but more affordable dual-core models will have to wait for almost a month and a half. «People’s» Pentiums do not even fall into the first quarter.
But still, one and a half — not four, Pentium will appear much more than one, prices for them are expected to be more humane than for a single processor (well, one and a half) of this family under LGA1156, and Celeron are visible on the horizon: in a word, in the company took into account the experience of the «stretched start» LGA1156 and most likely will not make such mistakes. Thus, starting from the second or third quarter of this year, LGA1155 will finally allow to abolish the healed LGA775 construct, and by the end of the year will also do away with LGA1156. But for some time these three platforms will exist in parallel, which, coupled with the surviving LGA1366 (and it will definitely live until the end of the year), will only increase the confusion on the market. However, these are the harsh realities of the modern market and we can hardly change them in any way. It remains only to carefully study everything and always make the right choice 🙂
There will be no theoretical part today. The fact is that we already had materials on this topic, and more detailed studies of microarchitecture are just around the corner. In general, we will not beat the bread from the theorists 🙂 Also, for now, we will leave behind the scenes the issue of performance and functionality of the graphics core — this is also a separate and serious topic, which we will return to for a detailed study in the near future. At the moment, the main thing is to study the performance of the processor part itself and compare it with competing products from both Intel and AMD. To what we propose and go.

In the family of processors under LGA1156, two processors of the Core i7 line and only one Core i5 first appeared, but now the ratio is reversed — one to three. The explanation is simple: the older Core i7-800s are still on the market and have adequate performance, so don’t bother them too much. But the Core i5 is too motley company, which includes fast, but devoid of graphics processors of the 700th series and equipped with graphics, but rather weak (due to only two cores) Core i5-600. It is this imbalance that Intel decided to eliminate in the first place. Note that now Core i5 is is always four cores, and the «old» two-core/four-thread variant is only present in the cheaper Core i3 family. But these processors will be released a little later, since now the Core i3-500 is not so bad.
What does the performance comparison show? If earlier the Core i5-700 and Core i7-800 differed only in the presence / absence of Hyper-Threading support and frequencies, now the differences have become a little deeper: the i5 also has less cache memory. Moreover, the line is built in an interesting way — the step of the starting clock frequencies is uneven, but here at the maximum frequency in the boost mode “everything is right”: a hundred in the index is equal to 300 MHz of the clock frequency. A very serious difference, since both Intel and AMD have already accustomed us to the fact that neighboring processors in the line differ only by one multiplier. It is still difficult to say whether the concept will continue in the future or whether the company will go to tighten the ranks, so we will postpone this issue for the future. In our opinion, «do not part» is very useful — there are already too many processors on the market, in which it is too easy to get confused. But there may be some progress — otherwise the Core i5-2300 looks a bit strange, whose price is only slightly lower than that of the 2400, but the clock frequency lag is greater than the difference between the older models. Unless in one-two-threaded applications, it is reduced, but there are fewer and fewer of them. Moreover, the presence of background processes “votes” in favor of multithreading, which sometimes require not so few computing resources (and some of these background applications have also become multithreaded).
But with the Turbo Boost mode itself somehow … More was expected. And the maximum increase has decreased to 400 MHz (do not forget that one «new» step is equal to 3/4 of the old one), and the dependence on the number of working cores has not gone away, although there were rumors that now it is possible to increase the frequency of all cores to the maximum. The only significant change is that now processors have the right to overclock «to the last»: the boost mode is allowed to the TDP level (it used to be turned off at a lower limit), and if necessary, for a short time — even higher. Thus, a certain increase in performance under heavy load should be observed. Which one, let’s check.
The main thing for overclockers is that Turbo Boost in the new incarnation also supports such a feature as «Limited Unlocked Core» — the ability to set multipliers to «Max Turbo +4». That is, in other words, according to the Intel documentation, a completely ordinary Core i7-2500 will be able to operate at a frequency of 3. 9 GHz when all cores are loaded, and when only one is loaded, it will even reach a frequency of 4.1 GHz! The reality turned out to be even more interesting — the Gigabyte board, on which we tested the new family, of course, limited the multipliers, but … But for the 2600, for example, the maximum value (namely 42) could be set for any number of active cores, i.e., with a flick of the wrist, a 3.4 GHz processor turns into a 4.2 GHz model. And we have strong suspicions that other boards based on the P67 chipset (with the possible exception of those made by Intel itself) will behave in the same way.
P67 boards also support «Fully Unlocked Core», which allows using a multiplier up to 57 in any mode. However, this requires a K-series processor. Note that they are of interest not only to overclockers (and maybe not so much to them: as shown above, you can add 700-800 MHz on conventional processors): the K-series uses the HD 3000 series video core, but in conventional models — only only HD 2000, in which half of the execution modules are disabled. Thus, these processors will also be extremely useful for fans of integrated graphics, who will use them on motherboards based on the H67 chipset. But on the P67, it will not work to use the built-in video core (since there is no FDI link in it), but it will be possible to fully «retreat» during overclocking, as mentioned above. Moreover, when overclocking not only cores, but also memory: despite the fact that the officially supported maximum mode is DDR3-1333, this is true only for H67. On the P67, higher multipliers are also available, which gives memory frequencies up to 2133 MHz. And the TDP level on these boards can be adjusted manually, increasing it during overclocking or, conversely, reducing it to save energy (which was previously available only for extreme processors). In general, when developing processors and chipsets for LGA1155, Intel took into account all past experience, putting things in order in their comparative positioning 🙂 9
9001 2 —
As expected when testing a new family of processors, there will be more competitors than test subjects. Especially competitors produced in the same factories. The company of Intel processors we selected at first glance looks too colorful, but the selection logic is simple — the table (from left to right) shows:
- The fastest processor for LGA1156 equipped with a graphics core (it costs, by the way, like the Core i7-2600)
- The fastest Core i5 of the previous generation (has the same starting frequency as the new Core i5-2300, price — as Core i5-2500)
- The fastest Core i7 for LGA1156
- The fastest quad-core x86 processor
- In general, the fastest x86 processor 🙂
The last two models, of course, we need mainly out of curiosity — any LGA1155 processor announced today is not ashamed to lose to them 🙂 However, there are serious suspicions that the «extreme» i7-9 will loseThe Core i7-2600 won’t be able to achieve 75 Extreme (no matter how hard it tries), but a comparison with the i7-980X in a wide range of applications is of considerable interest.

Now let’s move on to AMD. It is obvious that when the heavy equipment of the “blue” enters the battlefield, only guerrilla warfare and ambush actions remain “green”. In any case, this situation will last until the Superwaffe, codenamed «Bulldozer», rolls out of the laboratories, but there is quite a lot of time left until that moment. Today we will not touch the «Green partisans», in the form of hordes of various Athlon IIs, but we will consider a couple of «tank ambushes». The first will be Phenom II X4 9 already familiar to our readers.70 is the fastest guaranteed quad-core processor on the market (Core i7-2600 only reaches 3.5 GHz in boost mode, and others are not capable of that either). As the second — Phenom II X6 1090T. The launch of this line last spring allowed the company to return to the $200-$300 market segment again, as the processors very successfully occupied a niche between the older Core i5 and younger Core i7 — let’s see if they manage to maintain their positions taking into account the renewal of the product range Intel. To be fair, both the X4 and X6 families are expecting replenishment in the near future (more precisely, 1100T appeared at the end of last year, and 975 — now), but since we are talking about only a slight increase in the clock frequency, it is obvious that the presence of slightly more productive ones than the ones used will not change the qualitative picture.

Performance testing methodology (list of software used and testing conditions) is described in detail in a separate article. For ease of perception, the results on the diagrams are presented in percentages (the result of AMD Athlon II X4 620 is taken as 100% in each of the tests). Detailed results in absolute terms are available as a spreadsheet in Microsoft Excel format.
The very first group of programs — and the first discoveries. As we already know, these tasks do not require a large number of computational threads, so the speed with which these same threads (in the amount of two or three) are «run» through the processor comes first. That is, in other words, this is exactly the area where architecture optimizations can have the best effect. And they did — already the Core i5-2300 (the youngest and cheapest) overtook all the processors that we tested earlier. Including extreme Core i7-975, which no one has been able to beat in this test so far. The remaining representatives of the new architecture, for obvious reasons, are even faster, so there is simply no one to compete with them.
It seems to us that Sandy Bridge will have the last word in these tasks when the new AVX vector instruction set is supported in programs. So far, this is “pure” mathematics, and very well parallelized, so the more computation threads, the better: the force breaks straw. However, the high efficiency of each computation thread affects here as well. In particular, the new Core i5 is faster than the old ones with the same number of cores and at a comparable clock frequency by 10 percent (looking at the diagram, do not forget that the i5-760 in boost mode runs at a frequency of 2.93 GHz, while the i5-2300 is only 2.9 GHz). But the transition to a thinner process technology allows the new processors to run at higher frequencies, so they can compete with both the old Core i7 and the six-core Phenom II X6. And with the latter — even despite their higher frequency;) However, there are no miracles in the world, so six-core Core i7 are out of reach, but they are much more expensive. Therefore, the second place of the Core i7-2600 is actually not a defeat, but a brilliant victory.
Scientific and engineering computing
Another basically low-flow group with a few multi-thread interspersed that distinguishes it from the first. But not much — the first two places were taken by processors under LGA1155 (the first was shared by as many as two, which once again shows that Hyper-Threading technology is still far from «free»), and the «penny» Core i5-2300 lost only to «multi-ruble» extreme processors of previous families.
As we have already written more than once, the applications included in this group have very different preferences: Adobe Photoshop «loves» a lot of calculation threads, while the three «amateur» programs do not need them (and even interfere at times). Well, since there are three of them for one, it is not surprising that the dual-core (but high-frequency) Core i5-600 showed very good summary results earlier. Only extremals gave out more, where there are a lot of cores, and the frequencies are also rather big. «Family 2000» suits these programs even better, and in Photoshop its results are very good — here you have new leaders. In particular, the Core i7-2600 shocked, which almost caught up with the much more expensive six-core Core i7-9 in the Adobe software package.70, and in the three remaining applications it simply has no competitors. The Core i5-2400 in them also showed a similar performance to the Core i5-680 (previously leading), but outperformed it in Photoshop by almost a factor of one and a half, which allowed this inexpensive model to take its place among the former leaders in terms of the totality of results. The Core i5-2500 is understandably faster than them and only behind the Core i7-2600. In general, only the youngest Core i5-2300 did not shake the imagination. Although if you remember that its wholesale price is only $ 177, and it “didn’t shock” against the background of processors for a whole hundred (or even all four — if you remember how much the Core i7-880 costs, to which the “baby” from the new line somewhat closer than to the equal frequency Core i5-760) more expensive dollars, this is also just a wonderful result.
7-Zip is able to use as many cores as it finds, all three subtests strongly «like» a large amount of cache memory, and the latter seems to be only interested in it — in general, it’s not surprising that here are the new Core i5 did not perform as well as in the previous groups: only four threads and a cache reduced to 6 MB make themselves felt. But «not perfect» does not mean bad — they easily bypassed all AMD processors and managed to reach about the level of the old Core i7, which cost about a hundred more. But the new Core i7-2600 has Hyper-Threading support and 8 MB cache, so its only competitor is the extreme Core i7-980X (even 975 is slower).
Visual Studio turned out to be not the most loyal application to new processors, apparently due to the fact that the compilation task was already one of the best optimized ones. However, the Core i5-2300 slightly outperformed the Core i5-760: taking into account the smaller cache memory capacity (which is of considerable importance in this test) of the new product, this deserves a positive assessment. The increase (albeit small) is actually of strategic importance — as we remember, earlier in this program the Phenom II X6 were very good, located above the Core i5 and with older models reaching the younger Core i7. And now? And now with compilation quad-core (and «honest» — without any Hyper-Threading) Core i5-2400 copes with exactly the same speed as six-core Phenom II X6 1055T (albeit the youngest in the family, but more expensive)! And the next model with the 1075T index is not far behind, only one point ahead of the Core i5-2500. The older models, as we can see, are still faster than even the new Core i5 and they can already be compared with the old Intel processor at the $294 bar, but the new one for the same money has galloped far ahead, and is only behind six-core processors of the Intel itself. Moreover, it cannot be said that it is very noticeable — some 10% separates it from the current extreme Core i7-980X.
But SPECjvm was a bit of a surprise, since we’re used to citing this test as a good example of multi-core optimization. However, apparently, its capabilities extend to an area with eight to ten streams, but no more. While processors with a different number of cores competed, but based on similar architectures, this gave an obvious priority to more multi-threaded models, but as soon as we started comparing models with different efficiency per thread … In general, Core i7-980X is still the fastest, but the advantage over the Core i7-2600 has become purely formal. Well, the Core i5-2400 somehow «didn’t notice» that the Core i7-880 supports twice as many computational threads and has a close clock speed, and almost caught up with it 🙂 The 970 was faster than any Core i5, and the Phenom II X6 1090T outperformed any Core i7-800. Now Phenom II X4 970 is slower than all Core i5 for LGA1155, and Phenom II X6 1090T is behind the Core i5 -2500. And it’s not surprising that with the new Core i7 for LGA1155, AMD’s six-core processors can no longer compete in terms of performance.
Previously, this group of applications was the most loyal to the Phenom II X4, since even the model with the 965 index bypassed all Intel processors. Now, as we can see, even the Core i5-2300 can repeat the results of the past tops, the Core i5-2400 outperforms the Phenom II X4 965 and only slightly falls short of 970, while the 2500 and 2600 are simply the fastest on the market. Without any reservations 🙂 However, as we have said more than once, from a practical point of view, it makes no sense to attach great importance to the results of these tests on top processors, but from a research point of view, we mark with a tick that, perhaps, the last group has disappeared, where AMD processors held the lead.
Another group of applications that can benefit greatly from the introduction of AVX over time, but so far operates only with «old» code. In addition, as has been said more than once, the testing conditions favor processors that are capable of simultaneously executing a large number of computation threads to the greatest extent. Therefore, at first glance, the new Core i5 is not so good here. But if you look closely, it becomes obvious that this is the level of the «old» Core i7 or Phenom II X6, i.e. more expensive CPUs. In any case, earlier, not a single quad-core crystal scored 150 points here, and now three are gaining more at once. The Core i7-2600, as one would expect, takes an honorable second place, trailing only the six-core (and twelve-thread) Core i7-980X.
Similar to the previous picture. Only now the gap between 2600 and 980X has become larger, but it can be done — after all, devices of completely different price classes. The main thing is that new devices are able to defeat not only direct competitors, but also processors that are one step higher.
Even this group of applications has run out of stagnation. After which we started to run into a far from the slowest video card — for example, in Stalker and Resident Evil 5, all new processors showed the same results 🙂 Which, it should be noted, turned out to be much higher than all the old ones. In general, the question of finding the best gaming processor, perhaps, should be considered resolved in all cases where you can spend more than $ 150 on a purchase — such is the Core i5-2300. Or, if finances are not so pitiful, then the Core i5-2400, which costs quite a bit more, but “keeps” at the level of former extreme sportsmen. Top-end video cards or multi-GPUs remain “behind the scenes”, but here, as it seems to us, the question of the price of the processor is not decisive. Moreover, even the Core i7-2600 is not too expensive. And you can also overclock it by 400-800 MHz if you wish … Or pay just a little extra for 2600K and overclock it even more. Or save a hundred and do the same procedure with the Core i5-2500K 🙂 In general, the only choice will be for those who need a fast processor for games for $ 100 or who, on principle, want to take something very expensive.
There was a time when the older Phenom II X4 models were sold at a price of about $300, but the introduction of the Core i5-750 «driven» all AMD processors into the «under $200» price niche. The company was able to get out of it only by releasing the Phenom II X6. Now, it looks like history is repeating itself: already six-core Phenom IIs should be sold at prices not exceeding $200 — to the delight of some fans, but to the dismay of shareholders. (After all, it is obvious that quad-core processors manufactured according to the 32 nm process technology are cheaper in production than six-core ones at 45 nm, despite the presence of a video core in the first ones.) So it will be interesting to see how the «green» get out of this situation — before the release of Bulldozer- there is still quite a lot of time left.
Another family of processors was not so lucky. Yes, in fact, the Core i5-600 can be sent to the dustbin of history in full force. While it was necessary to make a choice: “four cores or integrated graphics?”, There was something to talk about. However, now the choice is clear — four cores (faster than the old ones) and integrated graphics (faster than the old ones) at the same time . The new Core i5s are definitely better than the old ones. It looks a little strange, perhaps, the current pricing policy: the 2400 differs from the 2300 by as much as 300 MHz and only $ 7, and from the 2500 by only 200 MHz and as much as $ 20, but this is quite explainable by the premium for steepness. Moreover, maybe after the release of the new i3 (which will finally write off all the processors on the Clarkdale core), the “ladder” will be redone into 155-177-204, which will be more logical.
If the new i5s are so good, what about the Core i7-2600? An excellent processor, the absolute triumph of which was spoiled only by the extreme Core i7-980X. But even then only in the overall standings — it’s easy to see that in half of the test groups, even this expensive device can now compete only with the new Core i5, significantly pulling ahead only in a few cases. Yes, this is still a difficult share of six-core desktop environments: a very small percentage of software can make good use of their potential. It seems to us that Intel very correctly decided that the time for multi-core processors on the desktop has already come, but «a lot» still means «four». For thrill-seekers, you can do more, but only if they are willing to pay for it 🙂 And pay regularly — previously the same 980X competed only with the same extreme models, and now it doesn’t always win even with budget ones. And the previous extreme lost everywhere to the usual Core i7-2600. Top, but regular . In general, the standard practice for Intel is that the new family of processors is unconditionally better than the old one, and the older models in it are no worse than the old extreme ones. Moreover, what is gratifying, even fans of overclocking and other optimizations now do not have to prepare another thousand dollars: there are not so expensive Core i5-2500K and i7-2600K. And even more versatile than their predecessors in the K-series, as they are interesting not only with fully unlocked multipliers, but also with a more powerful graphics core.
Summing up, is the release of new processors successful? Yes, count. Even despite the changed design, which will once again force upgrade enthusiasts to change motherboards: the new processors are good enough that even the owners of systems with LGA1366 have a temptation to do this procedure (if only because changing some i7-920 to i7-970 will be more expensive and less interesting than getting i7-2600K on a new board) or LGA1156. Not to mention those who are still holding on to the LGA775 — it’s time to finally retire any Core 2 Duo, and Core 2 Quad too. Well, those who buy complete computers receive just a small gift from the company — for the same money as in December last year, they can buy about 20 percent more processor power 🙂

Best processor for socket 1155
Hello everyone! Today we will look at the best processor for socket 1155 — the most powerful server and home option that is suitable for gaming.
Socket LGA 1155 (also called h3) was released by intel in 2011. Designed for CPUs based on Sandy Bridge and subsequently Ivy Bridge.
Although it is no longer the newest computer slot, it still continues to be used in 2019. For PCs that don’t have too high performance requirements, this is one of the best options today. Consider which CPU is better and why.
Intel Core i7-2700K
One of the highest performing Sandy Bridge CPUs. Base frequency 3.5 GHz. Overclocking up to 4 GHz is supported. It comes with a good cooler that makes almost no noise even under high loads. There are 4 cores and 8 MB cache memory.
Intel Core i5-2400
