Hello dear guys. I love processors, and everything connected with them is interesting to me. It has always been interesting. And today we have such a topic - 1155 and 1150, what are the differences between the socket and what is the compatibility? I will say right away that there is no compatibility and close, since these are different sockets, although they are similar. 1155 is an older socket and supports two generations of processors like Ivy Bridge (3rd generation) and Sandy Bridge (2nd generation). Well, 1150 is already a newer socket, it supports Haswell generations (fourth generation) and Haswell Refresh. I now have exactly 1150 socket and stump (percent).
Oh, I almost forgot, socket 1150 is still a little bit unique - it, namely, motherboards based on the Z97 chipset, has support for Broadwell (fifth generation).
That is, in fact, socket 1150 supports two generations, but the second generation is somehow limited - only on the Z97 chipset. There were rumors that there might be support for the Z87, but in the end there is no support.
Well, now to the most important thing. Let's start with socket 1155. There are two of the best here, the first is the i7 2600K, there is also the i7 2700K, but it's hard to find. This processor belongs to the Sandy Bridge generation, that is, it’s kind of old for 2018, but still peppy, yes, you can really play on it! The second processor is already the Ivy Bridge generation - the i7 3770K model, well, this is already a suitable processor, of course, not like the new ones, but you can definitely play on it. By the way, another important plus of these processors is the price. For example, you can search for i7 2600K here, and if you search well, you can find it even for $100..
Now let's talk about socket 1150. Here everything seems to be even cooler. The coolest CPU is the i7 4790K, whose performance is not far from the i7 7700K (Kaby Lake generation). The price on the used market is also not the lowest, in general. This is the Haswell Refresh generation, I also remember that in order to support this processor, it was necessary to update the BIOS .. So, okay, the second processor is the coolest i7-5775C - generally a rare beast, if you can find it, it will definitely be expensive. Yes, and it only works on the Z97 chipset, it won’t work on others, it’s already checked.
Note to you - processors with the letter K means that they can be overclocked. Without it - it is impossible, and such prots are even cheaper. The only thing that is not clear to me is whether it is possible to overclock the i7 5775C, I read it on the Internet, it seems like it’s possible ..
That's it guys, now let's take a quick look at the characteristics, okay? Look, we start with the i7 2600K, I'll tell you a little in my own words. As I already wrote - the processor is good, worthy of respect. Has 4 cores, 8 threads. The frequency is 3.4 GHz, in turbo mode it rises to 3.8. The cache is 8 MB, in general, everything is fine with this processor, and you can play on it, and if you overclock it a little, it’s a bomb for ridiculous money. Here are the main features of the i7 2600K as a picture:
Now about the i7 3770K, it will already be a little better, the frequency is 3.5 GHz, in turbo mode 3.9, everything else is the same. The processor generation is newer, so it seems to be a little more productive .. but for the price of an i7 3770K you can buy an i7 2600K and normal cooling, there is something to think about. Here are the specifications of the i7 3770K as a picture, see:
So, now about the i7 4790K - well, this is already a normal processor, and you can call it that in our conversation. It carries new games, it has a normal frequency, but its used price is not quite normal. not 4.. Okay, the i7 4790K has a frequency of 4 GHz, in turbo mode 4.40, which is very good! Of course, the cooling is also desirable to be more or less. This percentage can be overclocked, then it can definitely last a couple of years, subject to normal cooling .. Here are the characteristics of the i7 4790K guys in the form of a picture:
Well, now about the most interesting processor - i7-5775C. It is unique in that it is the fifth generation, that is, even in some relevant for today, that is, for 2018. It is also made according to the 14 nm process technology, there is 6 MB of cache. That is, as if new. But the most important thing in this processor is a kind of eDRAM memory, thanks to which it is faster than all previous processors in some operations, despite the lower frequency. Yes, this is a good processor, I would like one for myself, but the price of it used is no, thanks. The frequency of the processor is 3.3 GHz, in turbo mode 3.7, and the most important thing, as I already wrote, is eDRAM memory, the volume of which is 128 MB .. So, here are the characteristics in the form of a picture:
By the way, do you see a question mark opposite eDRAM? I clicked on it and this message popped up:
These are the guys of business, here is such a dynamic RAM right in the processor chip!
That's all, I personally like the i7 2600K because of its price, after all 4 cores .. 8 threads .. and the possibility of overclocking. And I forgot to tell you the main thing - the i7 2600K has solder under the cover, that is, metal, not paste! Therefore, in theory it is better to overclock than others. And I just read that the i7 2600K can be easily overclocked to 4.6-4.8, and at this frequency the processor is already decently good! That's all, that's all, good luck to you and take care of yourself !!
For the first time, Sandy Bridge processors with LGA1155 appeared in 2010, replacing not the most successful processors with an LGA1156 socket and a Lynnfield core. The new processors had greater performance and, at the same time, heated up noticeably less. Models with an unlocked multiplier made it possible to achieve record frequencies at the time of release. In 2012, processors with the Ivy Bridge core, using the same LGA1155 processor socket, saw the light. These chips belong to the third generation and differ, first of all, in support of PCI-E version 3.0. Thanks to this, those who supported them as quickly as Sandy Bridge gained popularity. Video card manufacturers also contributed to this by releasing top-end solutions with such an interface. For the sake of objectivity, it should be noted that the third generation processors had less overclocking potential compared to the second generation.
Socket LGA1150
Socket LGA1155
The fourth generation processors, Haswell, replaced Ivy Bridge. They brought with them not only a new level of performance, but also a new processor socket. The graphics integrated into the processor has undergone a major upgrade, and the performance has reached values that allow you to play simple games quite comfortably. Almost simultaneously with the fourth generation, fifth-generation processors with the Broadwell core were released, which, at lower power consumption, provide performance similar to Haswell.
The presented table allows you to compare the listed processors:

To compare performance, consider 3 older processors of the second, third and fourth generations. The fifth generation does not make much sense to consider, since these CPUs are not created for high performance, but to improve performance per watt. Therefore, they are inferior in speed to fourth-generation processors.

The test results show how the performance of processors has increased from generation to generation. The exception is gaming test based on Crysis Warhead. This is due to the fact that this game uses only one processor core in operation, and the main performance criterion is the clock frequency. It can be seen that the Core i7-3770 as having the lowest clock speed showed minimum performance. All old games behave in a similar way, so if you like World of Tanks or Crysis, then changing the second or third generation processor is pointless. For modern games such as GTA 5, The Witcher 3 or Project CARS, a newer processor will allow you to get better performance. For tasks such as photo and video editing, mathematical calculations, and more, switching from to makes sense. Especially considering that modernization will require the replacement of only and. The remaining components can be used from the old system.
Let's turn to energy consumption. Consider Core processors i7-2700K, Core i7-3770K, Core i7-4790K installed in a system where the Radeon HD 7970 graphics card is the second notable power consumer. The processor load was provided by a performance test built into the 7z archiver and capable of loading all processor cores in the system
The power consumption of the processor depends on its heating. Those. the more the processor consumes, the better it needs to be cooled. Accordingly, the cooling system of a more economical processor, other things being equal, will be quieter. The power consumption table shows that the second generation Core processors have the highest power consumption. With processors of the third and fourth generation, everything is a little more complicated. The tested processors showed a funny result: in idle, the Core i7-4790K turned out to be better, and under load, the Core i7-3770K. However, it should be taken into account that modern processors it is quite rare that they run at full load, so it is important that the CPU can effectively reduce power consumption. Based on this, it can be argued that in non-extreme operating modes, the Core i7-4790K will have less power consumption.
Hello tech blog readers. Today I will tell you which processors are suitable for socket 1151 (Skylake, Kaby Lake), as well as 1151v2 (Coffee Lake). In this article we will try to talk about the most powerful, inexpensive and cheap chips. Intel Core, Pentium and Celeron.
The list of CPUs will be listed in order to give you a more accurate idea of the models on the market.
And yes, it's worth making an important clarification: the LGA1151 socket is not backward compatible with the 1150 and does not support Xeon server processors.
Processor compatibility table
Socket 1151 from Intel is very insidious in its essence, since it has 2 versions: the first supports chips of the 6th and 7th generations, and the second only supports the 8th. In relation, the picture is much simpler, but it is not about him. 
Let's see which ones, as well as i3, i7, Pentium and Celeron, are capable of running on 1151 Gen 1. 
Now let's look at the line of chips that will fit the motherboard with socket 1151v2. 
In 2018, 9th generation CPUs were added to the previous list. 
The best processor for its price
And now the most interesting part of the comparison. We have indicated which processor fits a particular socket. Now it remains to decide on the model of the chip itself. If you want to learn more about the CPU, we recommend reading this article. 
And now let's go through the brightest representatives of the 6th, 7th and 8th generations:
skylake– Intel i5 6400T engineering sample. In my time given processor made a lot of noise, because it had an extremely low cost, 4 productive cores with a frequency of up to 2.8 GHz and a very modest heat pack of 35 watts.
Kaby Lake– Intel Pentium G4620. The so-called "Hyperpen" became a cult among gamers at the time of release, as it offered the functionality of the Intel Core i3-7100 at a significantly lower cost. It is also worth mentioning the peppy mid-range i5-7400 and the top version of the i7-7700k, which has 4 cores and 8 data processing threads. The stone is still considered relevant, powerful and interesting solution for progressive systems, and also supports overclocking up to 5 GHz by a multiplier.
Coffee Lake– i5-8400. The advent of the 8th generation of Intel chips added not only a new socket, but also 2 additional cores of each line, with the exception of Celeron and Pentium. Having a 6-core processor that can automatically increase the frequency from 2.8 to 4 GHz is a very successful investment in the future and therefore I recommend it boldly (at i5 prices, you can find out about this (especially since this discounter is well known to many as reliable and verified seller.
Difference between1151 and 1151v2
It has long been no secret that a processor socket designed for chipsets of the 100th and 200th series is completely incompatible with the 300th. And it's not even that Intel wants to make more money. The introduction of additional cores forced engineers to radically redesign the power supply scheme of Coffee Lake processors in order to ensure stable operation of the chips, even under extreme overclocking. 
Key changes have been made to the VCC (power) and VSS (ground) pads. At the same time, the number of previously reserved RSVD contacts was slightly reduced. Thus the situation is as follows:
| Skylake/Kaby Lake | coffee lake | |
| VCC | 110 | 128 |
| VSS | 364 | 378 |
| RSVD | 46 | 25 |
As you can see, it is physically impossible to "make friends" of old chips with new motherboards, just like plugging a Chinese plug into a European socket. Yes, there are enthusiasts who managed to get Kaby Lake on the Z370 by modifying the BIOS, but the lion's share of the functions in this case was unstable, and the rest were completely absent.
So if you have a lot of free time - you can try, but I strongly do not recommend doing this.
I hope that the article was useful to you, so comment, share with your loved ones. See you in new articles. Bye.
Processor socket LGA 1150 or Socket H3is intended for processors that the companyIntelpresented in 2013. This
4th generation processors with integrated graphics core.
LGA 1150 designed to replaceLGA 1155 and is intended for processors on the coreHaswell.
In 2013 Intel announced crystals (processors) under the code name Ivy Bridge, they were designed on 22nm technology and replaced 32nm processors in the market Sandy Bridge. At the same time, the computing cores have not changed, but the graphics component has undergone major changes. The transition to new processors was not without consequences, processors based on 22nm technology turned out to be much worse overclocked than their predecessors. In this regard, fans of micro Intel processors with hope we waited for the correction of the situation in the upcoming products. They just became processors Haswell.
Long before the release of new processors, the Internet was filled with numerous speculations about the unprecedented overclocking potential and excellent performance of processors based on a processor socket. socket 1150.
Let's take a look at the new processors with technical side. New s1150 i3, i5, i7 processors have an integrated graphics core Intel HD Graphics 4600, much more powerful than s1155 i3, i5, i7 which are equipped with only Intel HD Graphics 2500. This is a very weighty argument for those who are going to work on systems without a separate video card and plan to use the integrated graphics core.
Details of the new microarchitectureHaswell.
The manufacturer decided not to increase the number of cores in new processors i5 And i7, as it was, for example, in the processors of the competing company AMD (recall that the processors AMD performed on a socket AM3+ had 2,4,6 and 8 cores). The motive was the excellent performance of quad-core systems.
The use of the latest technological process made it possible to place a hitherto unthinkable number of semiconductors - 1400 million on a crystal area of 177 mm². These transistors have a three-dimensional structure, similar to the structure of the first processors based on 22nm technology. Ivy Bridge. This structure is called Try Gate and thanks to it, transistors are small and leakage currents are minimized. This set of solutions not only reduced the cost of the product, but also resulted in a reduction in power consumption compared to processors using the 32nm process technology.
Let's look inside crystalHaswell. Inside it are 4 computing cores, a third-level memory array, graphics accelerator and "system agent", which includes the controller random access memory DDR3, image transmitters, bus controllers PCI And DMI. A high-speed bus is used for communication between internal blocks in a crystal, processor cores and integrated graphics use a common cache memory.
As for computing cores, the changes compared to Ivy Bridge are in the nature of optimizations, the design of the computational pipeline is the same. Has been increased throughput task manager due to the addition of two ports, improved sampling and branch prediction mechanisms, optimized buffer in the second level cache Translation Lookaside Buffer, as well as during the operation of virtualization technologies, delays were reduced. There were also minor changes in the operation of vector construction blocks - they received support latest instructions, accelerating cryptographic operations, media processing and caching. The depth of data fetching from the cache memory of the first and second levels per cycle has doubled, which means that the processors Haswell can noticeably outperform their predecessors in optimized tasks.
The numbers 1150 or 1155 next to the name of the models of Intel processors and motherboards for them indicate the type of socket - a pad that allows the two main nodes of the system to interact with each other. The development of these interfaces is inextricably linked with the development of CPU lines, so they become obsolete and are replaced at the same time. In the characteristics, an indication of the socket - essential information, which determines the configuration of the system, because a mismatch is fraught with incompatibility of the processor and motherboard. Let's evaluate the difference between 1150 and 1155, and get ready for the choice of components.
LGA 1155(or Socket H2) is a socket for Intel processors with 1155 pins, released in 2011.
LGA 1150(or Socket H3) is a 1150-pin socket for Intel processors released in 2013.
As you can see, the numbers in the names of the sockets are by no means random - they coincide with the number of processor contacts intended for installation on the motherboard pad. This physical indicators, and the practical difference between 1150 and 1155 lies in which CPU models can be used with them. In a word, it is not the connector that colors the system, but what is in the connector.
Comparison
The physical dimensions of both considered types of LGA are identical: 37.5 x 37.5 mm. The number of contacts, respectively, is 1150 and 1155. Both their placement and the location of the key slots differ, so you won't be able to accidentally install the processor in someone else's socket. Manufacturers of cooling systems sometimes confuse the issue of compatibility by releasing coolers with mounts for 1150/1155. In this case, it seems to some users that the interfaces are identical, but in fact, the latches of the cooling systems are not related to the processor pads.
As mentioned, the LGA 1155 socket appeared in 2011 along with and for SandyBridge processors. In 2012, the successor IvyBridge fit into the same connector, which received a performance boost and support for PCI-E 3.0. In 2013, the world saw Haswell with an interface already 1150, in 2014 DevilsCanyon joined the family, in 2015 - Broadwell, and they very successfully replaced the previous lines. It's easy to see the difference between 1150 and 1155: two calendar years and four generations CPU Intel. One could say that the processors on these sockets are already outdated and out of date, but they are still on sale, moving from the top segment to the mass market.
Starting with the Haswell line, Intel processors received graphics cores from HD Graphics 4600 and higher, therefore, we can assume that LGA 1150-based configurations are in any case more powerful than 1155 in terms of the integrated video subsystem. However, it is the CPU that determines this gain, and not the socket.
