Socket 1155. LGA1155 Core i5 and i7 processors

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

Over the past few years, the situation has changed slightly, 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 Intel processor sockets 2017 that are still supported.

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

New processors usually need a different set of pins, which means a new socket appears. However, in some cases, processors remain compatible with the previous ones. The socket is located on the motherboard and cannot be upgraded without completely replacing the board. This means that upgrading the processor may require a complete reassembly of the computer. Therefore, it is important to know what socket is in use on your system and what you can do with it.

1. LGA 1151

LGA 1151 is Intel's latest socket. It was released in 2015 for the Intel Skylake processor generation. These processors used a 14 nanometer process technology. Since the new Kaby Lake processors haven't 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 LGA 1150, there is support for USB 3.0, DDR4 and DIMM memory modules are optimized, and support for SATA 3.0 is added. DDR3 compatibility has been retained. Of video, DVI, HDMI and DisplayPort are supported by default, and VGA support can be added by manufacturers.

LGA 1151 chips only support GPU overclocking. If you want to overclock the processor or memory, you will have to go for 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.

Here are the processors currently running on this socket:

3. LGA 1155

This is the oldest supported socket on the list for Intel processors. It was released in 2011 for the second generation Intel Core. Most processors in the Sandy Bridge architecture run on it.

The LGA 1155 socket has been used for two generations of processors in a row and is also compatible with Ivy Bridge chips. This means that it was possible to upgrade without changing the motherboard, just like now with Kaby Lake.

This socket is supported by twelve motherboards. The older lineup includes the B65, H61, Q67, H67, P67 and Z68. They were all released in conjunction with the release of Sandy Bridge. The launch of Ivy Bridge brought the B75, Q75, Q77, H77, Z75 and Z77. All boards share the same socket, but some features are disabled on budget devices.

conclusions

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

Latest Intel socket 1151, supported by Skylake and KabyLake processors. It can be assumed that the CoffeLake processors, which will be released this summer, will also use this socket. There have been other types of Intel sockets in the past, but these are very rare.

# Socket_LGA1150 # Socket_LGA1155

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 better 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. 2012 saw the release of Ivy Bridge processors 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. Because of this, their supporters gained popularity just as quickly as Sandy Bridge. This was facilitated by the manufacturers of video cards 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, 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 modernization, and the performance has reached values that 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 table below allows you to compare the listed processors:

Specifications	LGA1155		LGA1150

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

Specifications	LGA1155		LGA1150
Chipset	Z68	Z77	Z87	Z97
Maximum number of PCI Express slots		8 slots using up to 8 PCI-E 2.0 lanes	8 slots using up to 8 PCI-E 2.0 lanes	8 slots using up to 8 PCI-E 2.0 lanes

SSD caching technology		Intel Smart Response Technology	Intel Smart Response Technology	Intel Smart Response Technology

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.

Crysis Warhead DX10 640 * 480 Mainstream

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, 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 the same Crysis, then it makes no sense to change the processor of the second or third generation. For modern games like GTA 5, The Witcher 3 or Project CARS, a newer processor will give you better performance. For tasks such as photo and video editing, mathematical calculations, and so on, 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 noticeable consumer of energy is the Radeon HD 7970 video card. the system

The heating of the processor depends on the power consumption of the processor. Those. the more the processor consumes, the better it needs to be cooled. Accordingly, the cooling system of a more economical processor, all other things being equal, will run quieter. From the power benchmark table, you can see that the second 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 is able to effectively reduce power consumption. Based on this, it can be argued that in non-extreme operating modes, it is the Core i7-4790K that will have lower power consumption.

Not so long ago one could observe an abundance of solutions based on x86 architecture from various manufacturers. AMD, Cyrix, Intel, VIA, NEC, NexGen, Transmeta, SiS, UMC - all of them produced integrated circuits suitable for a certain range of tasks. Today we can only mention two players on the market, which, however, need no introduction.

Despite the overly modest list of desktop CPU manufacturers, the number of models of ready-made devices is now dizzy. Celeron, Pentium, Core i3, Core i5, Core i7 - this is just a list of lines of modern Intel solutions. How not to get lost in the maze of all these names?

Modern central processing units and platforms

Intel Haswell (LGA1150)

Processors based on the Haswell microarchitecture are currently the crowning achievement of Intel. The chips are manufactured using a 22-nm process technology. The architecture itself, in comparison with Ivy Bridge, has received a number of significant changes and improvements:

new instruction sets AVX2.0 and FMA3 are used;
increased bandwidth of the cache;
increased buffer and queues, including reordering buffer;
iVR voltage regulator is built directly into the processor;
the number of launch ports has been increased from six units to eight, and new executive devices have been added;
added new energy saving modes;
increased virtualization speed.
