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

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

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

Processor compatibility table

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

The best processor for its price

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

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

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

Coffee Lake– i5-8400. The advent of the 8th generation of Intel chips added not only a new socket, but also 2 additional cores of each line, with the exception of Celeron and Pentium. Having a 6-core processor that can automatically increase the frequency from 2.8 to 4 GHz is a very successful investment in the future and therefore I recommend it boldly (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.

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 between the processor and the 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. it physical indicators, and the practical difference between 1150 and 1155 is 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 of Intel CPUs. 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, so 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.

Processor socket LGA 1150 or Socket H3is intended for processors that the companyIntelpresented in 2013. it

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 Intel microprocessors were looking forward to fixing the situation in future 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, a graphics accelerator and a “system agent”, which includes a controller random access memory DDR3, image transmitters, bus controllers PCI and DMI. For communication between indoor units a high-speed bus is used in the chip, 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. The throughput of the task manager has been increased due to the addition of two ports, the fetching and branch prediction mechanisms have been improved, the buffer has been optimized in the second level cache Translation Lookaside Buffer, as well as during the operation of virtualization technologies, delays have been reduced. The operation of vector construction blocks has also undergone minor changes - they have received support for the latest instructions that speed up cryptography operations, multimedia 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.

To connect the computer processor to the motherboard, special sockets are used - sockets. With each new version processors got more and more features and functions, so usually each generation used a new socket. This nullified compatibility, but it allowed to implement the necessary functionality.

Over the past few years, the situation has changed a bit, and a list of Intel sockets has been formed that are actively used and supported by new processors. In this article, we have compiled the most popular 2017 Intel processor sockets that are still supported.

Before moving on to the consideration of processor sockets, let's try to understand what they are. A socket is a physical interface that connects the processor to the motherboard. The LGA socket is made up of a series of pins that align with the plates on the underside of the processor.

Newer processors usually need a different set of pins, which means there is a new socket. However, in some cases, processors remain compatible with previous . The socket is located on the motherboard and cannot be upgraded without a complete board replacement. This means that updating the processor may require a complete rebuild of the computer. Therefore, it is important to know which socket is used on your system and what you can do with it.

1. LGA 1151

LGA 1151 is the latest Intel socket. It was released in 2015 for the Intel Skylake processor generation. These processors used the 14 nanometer process technology. Since the new Kaby Lake processors have not been changed much, this socket is still relevant. The socket is supported by the following motherboards: H110, B150, Q150, Q170, H170 and Z170. The release of Kaby Lake also brought such boards: B250, Q250, H270, Q270, Z270.

Compared to the previous version of the LGA 1150, USB 3.0 support has appeared here, the work of DDR4 and DIMM memory modules has been optimized, and support for SATA 3.0 has been added. DDR3 compatibility has also been retained. From video, DVI, HDMI and DisplayPort are supported by default, while VGA support can be added by manufacturers.

LGA 1151 chips only support GPU overclocking. If you're looking to overclock your CPU or memory, you'll have to go with a higher-end chipset. In addition, support for Intel Active Management, Trusted Execution, VT-D and Vpro has been added.

In tests, Skylake processors perform better than Sandy Bridge, and the new Kaby Lake processors are a few percent faster.

findings

In this article, we looked at the generations of Intel sockets that were used before and are actively used in modern processors. Some of them are compatible with new models, while others are completely forgotten, but are still found in users' computers.

Latest Intel socket 1151, supported by Skylake and KabyLake processors. It can be assumed that CoffeLake processors, which will be released this summer, will also use this socket. There used to be other types of Intel sockets, but they are very rare now.

One of the most popular processor sockets from Intel at the moment is socket 1150. Although this platform is now gradually being replaced by the updated socket 1151, its semiconductor chips will definitely be relevant over the next 2-3 years, and it is its capabilities that will be considered in this article.

and its positioning

In 2013, the question was relevant when choosing a new PC: “Socket 1150 or 1155?”. There was virtually no difference in performance between these processor sockets. In terms of price, 1155 was preferable, but energy saving is an order of magnitude better for 1150. Now the latter is being replaced by a more progressive family of processors - the sixth, which is already installed in socket 1151. Otherwise, it should be noted that socket 1150 allows you to create the most affordable computer systems. But the segment of the most productive PCs and servers is mostly occupied by socket 2011.

Segmentation of processor solutions

Socket 1150 in terms of processor solutions was divided as follows:

Solutions for computer enthusiasts are AI5 and AI7 processors with the K index. They have an unlocked multiplier, and with proper selection of the PC configuration, this nuance allows you to get a significant performance boost.

The most productive AI7 chips were perfect for building the most computationally demanding computers - servers, graphics and workstations, and gaming PCs. Ai5 is also aimed at the same niche, but their performance level is lower than that of Ai7, but at the same time the price is more modest.

The middle segment of this platform was occupied by solutions based on Ai3. This family of CPUs is great for most tasks. But in some cases (for example, in the most demanding 3D toys) you will have to sacrifice some parameters and this will not affect the gameplay process in the best way.

To build entry-level computers, it is most optimal to use the most affordable CPUs - Pentiums and Celerons. Their computing capabilities are quite enough to solve a wide range of office tasks.

Generation of semiconductor crystals "Haswell"

The first generation of chips for this computer platform was presented under the code name "Haswell", and at that time there was a dilemma: "Which is better to choose: socket 1150 or 1155?". The performance difference between the two was not significant. But the energy saving of the 1150 was better. All these chips were manufactured using the 22 nm process technology. The upper segment was occupied by Cor I7 4770K (overclockable) and Cor I7 4770 (in this case, the CPU multiplier was blocked). These chips could work in 8 computing threads and they had only 4 computing cores. The cache of the third level was equal to 8 MB, and their reference was 3.5 GHz. The Core Ai5 processors of the 4670K, 4670 and 4570 models occupied a little lower in terms of performance. In the first case, the CPU multiplier was unlocked and this made it possible to obtain a significant increase in performance. The first two models had a CPU frequency of 3.4 GHz, while the latter had 3.2 GHz. The number of computing threads is limited to 4, and the third-level cache is 6 MB. Even lower in terms of performance are Cor Ay3. Their frequencies were reduced, the third-level cache was reduced, and the number of physical cores was 2 with 4 computational threads. The niche of the most modest processors was occupied by Pentiums and Celerons. Minimum frequencies, minimum level 3 cache and only 2 cores.

Another family of chips for this processor socket

The first generation of chips for socket 1150 turned out to be not entirely successful. Processors often overheated and failed during overclocking. As a result, Intel had to release an additional family of processors with improved thermal paste under the heat sink cover, which was code-named "Haswell Refresh". In fact, these are the same chips, but with a different marking. For example, Kor Ai7 4770K was renamed into Kor Ai7 4790K. In addition to improved thermal paste, these processor solutions boasted an increased frequency (in the 4790 it was 100 MHz higher).

Broadwell chip generation

Socket 1150 boasts support for 5th Gen Core processors, codenamed Broadwell. For desktop computers, only 2 chip models were released - "Cor Ai7 5775" and "Cor Ai5 5675". Their specifications were more modest than those of their predecessors: the frequencies were lower by 200 MHz. But the key innovation of these CPUs is an improved manufacturing process - 14 nm.

Chipsets

8th and 9th series of system logics for this platform. The initial niche was occupied by the H81, which could boast a minimal level of functionality. The middle segment was occupied by B85, Q85, Q87 and H87. Well, the most progressive solutions were built on the basis of the Z87. But only "Haswell" and "Haswell Refresh" chips (in this case it is recommended to update "BIOS") in these chipsets. Socket 1150 allows you to install Broadwell solutions, but they can only work in the 9th series of system logic. There are only 2 of them - H97 and Z97. These chipsets are designed for use in high performance PCs.

Further prospects for this computer platform

Every 2-3 years, Intel Corporation updates its computer platforms, and at the same time they are released with a new processor socket. motherboards. Socket 1150 was officially introduced in 2013 at the same time as the first Core 4th generation CPUs. Now, after 3 years, this platform is gradually being replaced by a newer processor socket (socket 1151), which installs the 6th generation of processors based on the Core architecture. As a result, it can be noted that the processor socket 1150 is living its last days. It's not that outdated. It is simply replaced by an updated computer platform. But its most productive CPUs will definitely be relevant for the next 2-3 years.

Intel processor sockets, as noted earlier, are currently changing from 1150 to 1151. And the 1150 platform is now at the end of its life cycle. But this does not mean that its processor solutions are not relevant. Right now they are of the greatest interest in model range chips from Intel. Prices for them have been reduced in light of the update for the 6th generation of Core processors, and the performance level between 4th, 5th and 6th generations is not so significantly different. Therefore, if you urgently need an inexpensive, but productive computer, then you can safely purchase a computer with the necessary equipment based on the Haswell or Haswell Refresh CPU. Well, Broadwell solutions are aimed at the niche of the most productive PCs, and in this case it is better to report a relatively small amount and purchase a system based on socket 1151.
