Intel processor sockets. What is the difference between LGA1150 socket and LGA1155 and which one is better Which socket is better 1151 or 1155

The numbers 1150 or 1155 next to the model names of Intel processors and motherboards for them indicate the type of socket - a contact pad that allows the two main nodes of the system to communicate with each other. The development of these interfaces is inextricably linked with the development of CPU lines, therefore they become obsolete and are replaced at the same time. In the characteristics, an indication of the socket is the most important information that 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 selection 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 socket for Intel processors with 1150 pins, released in 2013.

As you can see, the numbers in the name of the sockets are by no means accidental - they coincide with the number of processor contacts intended for installation on the motherboard platform. These are physical indicators, and the practical difference between 1150 and 1155 is in which CPU models can be used with them. In a word, it is not the connector that paints the system, but what is in the connector.

Comparison

The physical dimensions of both types of LGA under consideration are identical: 37.5 x 37.5 mm. The number of contacts, respectively, is 1150 and 1155. Their placement and the location of the key slots are also different, so it will not be possible to accidentally install the processor into a foreign socket. The manufacturers of cooling systems sometimes make confusion about 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 have nothing to do with processor sites.

As mentioned, the LGA 1155 socket appeared in 2011 along with and for SandyBridge processors. In 2012, the successor to IvyBridge fit into the same connector, which received performance gains and support for PCI-E 3.0. In 2013, the world saw Haswell with an interface of 1150, in 2014 DevilsCanyon joined the family, in 2015 - Broadwell, and they very successfully replaced the previous lines. It's easy to see what the difference is 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 outdated, but they are still on sale, having moved from the top segment to the mass one.

Starting with the Haswell line, Intel processors received graphics cores from HD Graphics 4600 and higher, so we can assume that configurations based on LGA 1150 are in any case more powerful than 1155 in terms of the integrated video subsystem. However, it is the CPU that determines this gain, not the connector.

fourth generation processors with integrated graphics.

LGA 1150 designed to replaceLGA 1155 and is designed for processors on the coreHaswell.

In 2013 Intel announced crystals (processors) under the code name Ivy bridge, they were designed with 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 correcting the situation in upcoming products. They just became the 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 new processors with technical side... The 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 powerful 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 i5and i7, as was the case, for example, in processors from a competing AMD company (recall that processors AMDexecuted on socket AM3 +had 2,4,6 and 8 cores). The motivation was the excellent performance of the quad-core systems.

The use of the latest technological process made it possible to place a hitherto unthinkable number of semiconductors - 1400 mln. On a crystal area of \u200b\u200b177 mm². These transistors have a three-dimensional structure, similar to the structure of the first processors based on 22nm technology. Ivy bridge... This structure was named Try-Gateand thanks to it, transistors are small in size and minimization of leakage currents is achieved. This set of solutions not only reduced the cost of the product, but also led to a decrease in power consumption compared to processors using a 32nm process technology.


Let's look inside crystalHaswell... It contains 4 computing cores, a third-level memory array, a graphics accelerator and a "system agent", which includes a DDR3 RAM controller, image transmitters, bus controllers PCIand DMI... A high-speed bus is used for communication between internal blocks in the crystal, processor cores and integrated graphics use a shared cache memory.


As for the computational cores, the changes compared to Ivy bridgeare in the nature of optimizations, the design of the computational pipeline is the same. The throughput of the task manager was increased due to the addition of two ports, the mechanisms of fetching and branch prediction were improved, the buffer in the second-level cache was optimized Translation Lookaside buffer, and virtualization technologies have reduced latency. Vector blocks have also undergone minor changes to support the latest instructions that speed up cryptography, media processing, and caching. The depth of data sampling from the first and second level caches per cycle has doubled, which means that the processors Haswellcan significantly outperform their predecessors in optimized tasks.

For the first time, Sandy Bridge processors with LGA1155 appeared in 2010, replacing not the most successful processors with LGA1156 socket and Lynnfield core. The new processors had higher performance and at the same time they warmed 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 saw the light, using the same LGA1155 processor socket. These chips belong to the third generation and differ, first of all, in support of PCI-E version 3.0. Thanks to this, their supporters gained popularity as quickly as Sandy Bridge. This was facilitated by the manufacturers of video cards, releasing top 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 LGA1155

The fourth-generation processors, Haswell, have replaced Ivy Bridge. They brought with them not only a new level of performance, but also a new processor socket. The graphics built into the processor have undergone a serious upgrade, and the performance has reached values \u200b\u200bthat make it quite comfortable to play simple games. Almost simultaneously with the fourth generation, the fifth generation processors with the Broadwell core were released, which, at a lower power consumption, provide performance similar to Haswell.

The presented table allows you to compare the listed processors:

To compare the chipsets that support these processors, let's take the older models whose names begin with "Z"

To compare performance, let's consider 3 senior 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 the sake of high performance, but to improve performance per watt. Therefore, they are inferior in performance to fourth-generation processors.

Intel Linpack x64 Solving a system of 10,000 equations 40.8741 Gflop / sec 49.8957 Gflop / sec 54.1917 Gflop / sec

The test results show how the performance of processors has increased from generation to generation. An exception is the gaming test based on the Crysis Warhead game. 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 the minimum performance. All old games behave in a similar way, so if you love World of Tanks or Crysis, then it makes no sense to change the processor of the second or third generation. For modern games such as GTA 5, The Witcher 3 or Project CARS, a newer processor will provide better performance. For tasks such as photo and video editing, mathematical calculations, etc., it makes sense to switch from to. Especially considering that the modernization will require replacement only and. The rest of the components can be used from the old system.

Let's turn to power consumption. Consider the processors Core i7-2700K, Core i7-3770K, Core i7-4790K installed in a system where the second notable energy consumer is the Radeon HD 7970 video card. The processor load was provided by a performance test built into the 7z archiver and capable of loading all processor cores in system

The heating of the processor depends on the power consumption. 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 run quieter. From the power benchmark table, you can see that the 2nd generation Core processors have the highest power consumption. With third and fourth generation processors, things are a little more complicated. The tested processors showed a funny result: the Core i7-4790K turned out to be better in idle, and the Core i7-3770K under load. However, it should be borne in mind that modern processors rarely work 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 modes of operation, the Core i7-4790K will have lower power consumption.

One of the most demanded 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 crystals will definitely be relevant within the next 2-3 years, and its capabilities 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 practically no performance difference between these processor sockets. From a price point of view, 1155 was preferable, but energy saving is an order of magnitude better in 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 subdivided as follows:

    The solutions for computer enthusiasts are the Ay5 and Ay7 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 increase in performance.

    The most productive Ay7 chips were perfect for building the most demanding computers for computing resources - servers, graphics and workstations, and gaming PCs. Ai5 is aimed at the same niche, but the level of their performance is lower than that of Ay7, but at the same time the price is more modest.

    The middle segment of this platform was occupied by solutions based on "Ay3". This family of CPUs is excellent for most tasks. But in some cases (for example, in the most demanding three-dimensional toys) you will have to sacrifice some parameters and this will not have the best effect on the gameplay itself.

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

Generation of semiconductor crystals "Haswell"

The first generation of chips codenamed "Haswell" was presented for this computer platform, and at that time there was a dilemma: "Which is better to choose: socket 1150 or 1155?" The performance difference between the two was insignificant. The 1150 had better energy savings. All these chips were manufactured using the 22 nm process technology. The upper segment was occupied by Kor Ay7 4770K (with overclocking capability) and Kor Ay7 4770 (in this case, the CPU multiplier was locked). These chips could work in 8 computational threads and they had only 4 computational cores. The cache of the third level was 8 MB, and the reference one was 3.5 GHz. Kor Ay5 processors of 4670K, 4670 and 4570 models occupied a little lower in terms of performance. In the first case, the CPU multiplier was unlocked and this allowed a significant performance increase. The first two models had a CPU frequency of 3.4 GHz, while the latter had 3.2 GHz. The number of computational threads is limited to 4, and the third-level cache is 6 MB. Kor Ay3 is even lower in terms of productivity. Their frequencies were reduced, the third-level cache was reduced, and the number of physical cores was equal to 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 the overclocking process. As a result, Intel had to release an additional family of processors with improved thermal grease under the heat sink cover, which was codenamed Haswell Refresh. In fact, these are the same chips, but with different markings. For example, "Kor Ay7 4770K" was renamed to "Kor Ay7 4790K". In addition to improved thermal paste, these processor solutions boasted an increased frequency (in the 4790 it was higher by 100 MHz).

Chip Generation "Broadwell"

Socket 1150 boasts support for the 5th Generation Cor processors, codenamed Broadwell. For desktop computers, only 2 models of chips were released - "Kor Ay7 5775" and "Kor Ay5 5675". Their specifications were more modest than those of their predecessors: frequencies lower by 200 MHz. But the key innovation of these CPUs is the 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 boasted a minimal level of functionality. The middle segment was occupied by B85, Q85, Q87 and H87. Well, the most progressive solutions were based on the Z87. But only Haswell and Haswell Refresh chips (in this case it is recommended to update the BIOS) into these chipsets. Socket 1150 allows the installation of Broadwell solutions, but they can only work in the 9th series of system logic. There are only 2 of them - Н97 and Z97. These chipsets are targeted at high performance PCs.

Further prospects for this computer platform

Every 2-3 years, Intel Corporation updates its computer platforms, and at the same time, motherboards are released with a new processor socket. Socket 1150 was officially introduced in 2013 along with the first 4th generation Kor central processing units. Now, after 3 years, this platform is gradually being replaced by a newer processor socket (socket 1151), in which the 6th generation of processors based on the Cor architecture is installed. As a result, it can be noted that the processor socket 1150 is living its last days. It's not that it's outdated. It is simply being 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 already 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 the lineup of Intel chips. Prices for them in the light of the upgrade for the 6th generation of Cor processors have been reduced, and the level of performance between the 4th, 5th and 6th generations is not that much 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's 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.
