AMD sockets: overview, specifications and processors. Intel processor sockets

Socket is a processor socket developed by Intel and made using Land Grid Array (LGA) technology. It is a connector with spring-loaded or soft contacts, to which, using a special holder with a grip and a lever, a processor that does not have pin contacts is pressed. The increase in the number of its contact pads is associated with the transfer of the North Bridge components directly to the processor crystal.

Socket LGA 775

Socket LGA 775 (or Socket T) is one of the most widespread sockets in Intel processors at the moment (Fig. 1). It is a connector with spring-loaded (or soft) contacts, to which a processor that does not have pin contacts is pressed using a special holder with a grip and a lever.

Socket T (LGA 775) defines the following parameters of the computer motherboard:

Processor socket type - LGA;

Processor form factor - Flip-chip land grid array;

Number of contacts - 775;

Bus used - Quad-Pumped FSB;

FSB frequency, MP / s - 533, 800, 1066, 1333 or 1600;

Processors size - 37.5 × 37.5 mm;

Plug-in processors: Intel Pentium 4 (2.66 - 3.80 GHz), Intel Celeron D (2.53 - 3.6 GHz), Pentium 4 Extreme Edition (3.20 - 3.73 GHz), Pentium D (2 , 66 - 3.60 GHz), Pentium Extreme Edition (3.20 - 3.73 GHz), Pentium Dual-Core (1.40 - 2.80 GHz), Core 2 Duo (Exxxx, except 6x05 and 8x35), Core 2 Extreme (X6800; Qхxxxx, except 9775 and 9300), Core 2 Quad (Qxxxx, except 9000 and 9100), Xeon (1.86 - 3.00 GHz), "Core" Celeron (1.60 - 2.00 GHz).

This connector uses a bus that is less efficient than that of AMD, but unlike the AMD Athlon bus, it is scalable. Since the Pentium 4 and Core 2 Duo processors do not contain a memory controller, this allowed Intel to use the older bus with a higher frequency in the new processors. However, the efficiency of memory and cache use (all other things being equal) is slightly lower than that of AMD processors. When switching to the new FB-DIMM memory, Intel planned to abandon or significantly modify this connector. However, the high power consumption of this memory made us reconsider the decision in favor of DDR3 and further develop this direction.

Socket LGA 1366 (Socket B)

Socket LGA 1366 (or Socket B) is the successor to the LGA775 processor socket for high-performance desktop systems and the LGA 771 processor socket for servers from Intel. Socket LGA 1366 (Fig. 2) defines the following parameters of the computer motherboard:

Processor socket type - LGA;

Processor Form Factor: Flip-chip land grid array;

Number of contacts: 1366;

Used buses: 3 DDR3 channels (the memory controller in the Core i7 9xx supports up to 3 memory channels, and each can have one or two DDR3 DIMMs, so motherboards on the LGA 1366 socket support up to 6 memory strips, not 4 like Core 2); 1 or 2 QPI connections (each 4.8 - 6.4 GP / s);

Voltage, V: 0.75 - 1.375;

Processor size: 45mm × 42.5mm;

Processors family: Intel Core i7 (9xx), Intel Xeon - LC, EC, W (35xx), W (36xx), EC, LC, E, L, X (55xx), E, ​​L, X (56xx), Intel Celeron P1053; the protective cover of the processors consists of nickel-plated copper, the substrate is silicon, and the contacts are made of gold-plated copper;

The minimum and maximum storage temperatures for Core i7 are: - 55 ° C and 125 ° C;

The maximum heat dissipation of Core i7 processors is 130 W, in idle mode it is 12-15 W, the efficiency of a standard Core i7 cooler drops sharply if the temperature inside the system unit exceeds 40 ° C.

Supports work with the updated voltage regulator module - Voltage Regulator Module 11.1. The latter supports a number of new features such as Power on Configuration (POC), Market Segment Identification (MSID) and Power State Indicator Input (PSI #). The VID_Select, VR-Fan and VR10 VID features have been removed from the VRM 11.1 arsenal. The increase in the number of contact pads is due to the transfer of the memory controller directly to the processor die and the use of the new QuickPath Interconnect protocol instead of the previously used Quad-Pumped Bus.

Since the processors for the LGA 1366 socket have replaced the FSB with QPI (QuickPath Interconnect), this means that the motherboard must use a chipset that supports QuickPath Interconnect (in 2012, this technology was already supported by the Intel X58 and Intel X79 chipsets).

Socket LGA 1356 (Socket B2)

Socket B2, also known as LGA 1356 processor socket, compatible with Intel Sandy Bridge processors. LGA 1356 is designed as a replacement for LGA 1366 (Socket B). It is a connector with 1356 spring-loaded contacts. LGA 1356 and LGA 1366 processors are not compatible with each other, since they have different slot locations (the main difference between LGA 2011 and LGA 1356 is the number of QPI buses: there are two of them on LGA 2011, and on LGA 1356 there is only one QPI bus, except In addition, LGA 2011 has two additional PCI-E 3.0 lanes, as well as support for a fourth DDR3 channel).

Socket LGA 1356:

Processor Form Factor: Flip-chip, LGA;

The number of contacts LGA 1356: 1356;

Used buses: 3 channels DDR3, QPI, DMI;

Processors: Intel Sandy Bridge.

Processors:

Skylake-U (BGA 1356) - for mobile devices (ultrabooks, thin and light laptops);

Skylake-H (BGA 1440) - high-performance laptops;

Skylake-Y (BGA 1515) - Fanless devices, tablets and hybrid gadgets.

Socket LGA 1156 (or Socket H)

Socket H (or LGA 1156) is the successor to the LGA 775 processor socket for desktop systems and the LGA 771 processor socket for mid-range and entry-level servers from Intel (Figure 3). It is an alternative to the more expensive platform based on the X58 chipset and LGA 1366 socket. The LGA 1156 provides support for processors with an integrated graphics adapter. Currently, for this processor socket, processors of the Core i3, i5 and i7 8XX families are produced, as well as cheap processors under the Pentium brand.

Socket LGA 1156 (Fig. 3) defines the following parameters of the computer motherboard:

Socket type: LGA;

Processor Form Factor: Flip-chip land grid array;

Number of contacts: 1156;

Used buses: 2 channels DDR3, DMI, PCIe 16x;

Processors: Intel Core i7 (8xx), Intel Core i5 (7xx, 6xx), Intel Core i3 (5xx), Intel Pentium G69x0, Intel Celeron G1101, Intel Xeon X, L (34xx).

LGA 1156, unlike LGA 1366, is directly connected to the chipset via DMI, instead of QPI and northbridge. It has two memory channels instead of three and a PCI-Express 2.0 x16 connection. Chipsets for motherboards with LGA 1156 are produced by Intel Corporation, including products for servers - 3400, 3420, 3450; for desktop machines - P55, H55, H57, Q57 (only the last three support the video embedded in the processor). The first was the P55 chipset, and therefore, if the motherboard was released before the release of Core i3, Core i5 6xx on the market, then to use them, you will need to update the BIOS (all chipsets and processors are at least partially compatible with each other, for example: on a motherboard with P55 You can put a Clarkdale processor, but its video core will remain unused, and a Lynnfield processor can be installed on H / Q (55/57), but the video outputs will also remain unused, and many server boards are equipped with third-party video).

Socket LGA 1155 (Socket H2)

Socket LGA 1155 is a processor socket for Intel Sandy Bridge processors, designed as a replacement for LGA 1156 (Socket H). Despite the similar design, the LGA 1155 and LGA 1156 processors are incompatible with each other and they have different slot locations. LGA 1156 Mount Cooling Systems are compatible with LGA 1155, which means you don't have to buy a new cooling system for new processors.

An important difference between LGA 1155 processors and chipsets compared to LGA 1156 counterparts is the twice as fast version of the DMI bus, which connects the processor to the chipset, which eliminates the bottleneck when using SATA 6Gb / s and USB3.0 controllers, and it also supports processors with an integrated graphics adapter (processors with up to eight cores will be released for this socket in the future). Socket LGA 1155 (Fig. 4) defines the following parameters of the computer motherboard:

Number of contacts: 1155;

Used buses: 2 channels DDR3, DMI, PCIe 2.0 16x;

Processor size: 37.5 × 37.5 mm;

Processors: Intel Sandy Bridge, Intel Ivy Bridge.

Chipsets Q65, B65, H61, Q67, H67, P67, Z68, B75, Q75, Q77, H77, Z75, Z77.

ProcessorsSandyBridge.Chipsets (Tables 2, 3) for Sandy Bridge (except for Q65, Q67 and B65) will support both Sandy Bridge and Ivy Bridge processors (even without a forced BIOS update). Systems based on Sandy Bridge processors officially support memory up to DDR3-1333, but in practice they successfully worked with memory at speeds up to DDR3-2133. USB 3.0 is not supported by any chipset (motherboard manufacturers arrange USB3.0 support with third-party chips).

ProcessorsIvyBridge. All motherboards with Ivy Bridge chipsets support both Ivy Bridge and Sandy Bridge processors. Processors of the Ivy Bridge family initially officially support RAM up to DDR3-1600, while Sandy Bridge only up to DDR3-1333. Owners of Ivy Bridge chipsets can also use overclocking for K-series processors.

Socket LGA 2011 (Socket R)

LGA 2011, also known as Socket R, is a socket for Intel processors that should supplant LGA 1366 (Socket B) in high-performance desktop systems.

The LGA 2011 platform (for Sandy Bridge-E) is positioned by Intel as a solution for creating PCs with the highest level of performance. A distinctive feature of the entire line of processors is support for a four-channel DDR3 memory subsystem (enthusiasts will have access to 4/6/8-core Sandy Bridge E processors with support for a 4-channel memory controller).

LGA 2011 processors will use the Sandy Bridge architecture, but will lose the overclocking limitations inherent in the LGA 1155 platform. The LGA 2011 platform will be able to work not only with processors of the Sandy Bridge-E generation, but also with their successors in the person of Ivy Bridge-E, or even later Haswell processors.

Socket LGA 2011 (Fig. 5) defines the following parameters of the computer motherboard:

Processor Form Factor: Flip-chip, LGA

Number of contacts: 2011

Used buses: 4 channels DDR3, QPI, DMI and 40 PCIe 3.0 lanes

Processor size: 58.5 × 50mm

Processors: Intel Sandy Bridge-EX

LGA 2011 uses the QPI bus to connect to an additional processor in dual-processor systems or to additional chipsets. The processor performs the functions of the north bridge, such as memory controller, PCI-E bus controller, DMI, FDI, etc.

For Intel Sandy Bridge-EP server solutions, the actual differences from Sandy Bridge chips will be a larger number of processor cores (up to eight), a corresponding LGA2011 processor socket, a larger L3 cache, an increased number of DDR3 memory controllers and PCI-Express 3.0 support. The structure of the chip can be roughly divided into the following main elements: processor cores, graphics core, L3 cache memory and the so-called "System Agent". To improve the overall performance of the system, the developers used a ring topology of a 256-bit interconnect bus, based on a new version of QPI (QuickPath Interconnect) technology, extended, modified and first implemented in the architecture of the Nehalem-EX server chip (Xeon 7500), as well as planned for use in conjunction with the architecture of Larrabee chips.

The ring bus is used to exchange data between six key components of the chip: x86 processor cores, graphics core, L3 cache, and system agent. Ring bus performance is rated at 96 GB per second per connection at 3 GHz, effectively four times the performance of previous generation Intel processors. The buses are controlled using the distributed arbitration communication protocol, while the pipelining of requests occurs at the clock frequency of the processor cores, which gives the architecture additional flexibility when overclocking. The bus consists of four 32-byte rings: Data Ring, Request Ring, Snoop Ring, and Acknowledge Ring; in practice, this actually allows you to share access to the 64-byte interface. last level cache into two different packages.

The ring topology and bus organization ensures the lowest latency in processing requests, maximum performance and excellent scalability of the technology for versions of chips with different numbers of cores and other components. In the long term, up to 20 processor cores per chip can be connected to the ring bus, and in addition, the physical ring bus is located directly above the L3 cache blocks in the upper metallization layer, which simplifies design wiring and allows the chip to be more compact. L3 - cache memory of the last third level (LLC) is distributed not only between the processor cores, but, thanks to the ring bus, also between the system agent.

The system agent includes a DDR3 memory controller, a Power Control Unit (PCU), PCI-Express 2.0 controllers, DMI, and so on. Like all other elements of the architecture, the system agent is connected to the overall system via a high-performance ring bus.

Each of the processor cores has direct access to its "own" L3 cache segment, while each L3 cache segment provides half of its bus width for ring data bus access, while physical addressing of all four cache segments is provided by a single hash function. Each L3 cache segment has its own independent ring bus access controller, which is responsible for processing requests for allocation of physical addresses. In addition, the cache controller constantly interacts with the system agent for unsuccessful L3 calls, control of inter-component data exchange and non-cached calls.

The power management controller located in the system agent is responsible for the timely and dynamic scaling of supply voltages and clock frequencies of processor cores, caches, memory controller and interfaces. It is especially important to emphasize that power and clock management is performed independently for the processor cores and the graphics core. This new version of Turbo Boost technology is not least thanks to this power controller. Depending on the current state of the system and the complexity of the problem being solved, the Sandy Bridge microarchitecture allows Turbo Boost technology to "overclock" the processor cores to a level that significantly exceeds the TDP for a fairly long time.

Although the locations of the mounting holes for the LGA2011 and LGA1366 sockets are the same, not all "old" coolers will fit the LGA 2011 (the LGA2011 mounting frame has a thread on the holes, which may require revision of the cooler mounting system). The maximum power consumption of processors within the LGA 2011 platform can be 150 watts. LGA 2011 was announced alongside Sandy Bridge-EX back in November 2011.

Socket LGA 1150 (or Socket H3)

Socket LGA 1150 - processor socket for Intel processors Haswell, and his successor Broadwell(start of production in 2013/2014, respectively). LGA 1150 is designed as a replacement for LGA 1155 (Socket H2). Socket LGA 1150 defines the following parameters of the computer motherboard:

Processor Form Factor: Flip-chip, LGA;

Number of contacts: 1150;

Used buses: 2 channels DDR3, DMI, PCIe 3.0 x16 / 2x8;

Processor size: 37.5 x 37.5 mm;

Processors: Intel Haswell, Intel Broadwell.

Haswell is the codename for a processor microarchitecture being developed by Intel, which is slated to be the successor to Ivy Bridge. Designed for 22nm transistor manufacturing technology with 3D gate structure.

Features of the architecture Haswell:

Technical process - 22 nm;

Design LGA 1150;

The basic number of cores is 2 or 4;

Completely new cache design;

Improved energy saving mechanisms;

Integrated vector coprocessor possible;

Adding Advanced Vector Extensions 2 instructions, in particular FMA (Fused Multiply Add);

Extension of TSX commands (en: Transactional Synchronization Extensions) for hardware support of transactional memory;

Power consumption is 30 percent lower compared to peers from the Sandy Bridge line (in addition, future chips will reduce platform power consumption during the standby period by more than 20 times compared to existing designs without sacrificing performance);

64MB eDRAM (single die but packaged).

The chip will implement the possibility of simultaneous operation with four operands, which will allow performing two multiplication and addition or subtraction operations at once in one instruction. Haswell can also acquire a cache of 4 levels, which will be used by the integrated graphics core to neutralize the impact of low bandwidth system memory. With the introduction of Haswell, Intel plans to split its product line into two groups: desktop and mobile; special versions for ultrabooks. Desktop versions of processors will come with two or four processor cores with TDP 35, 45, 65 or 95 watts, dual channel DDR3 / DDR3L memory controller, as well as integrated graphics cores GT2 and GT1. Mobile versions will also be available in dual- or quad-core configurations, but come with a more powerful GT3 graphics core and a DDR3L DIMM-only memory controller. Mobile computers based on Intel Haswell will be able to work without recharging for a whole day, and in standby mode with a network connection, this period will be more than 10 days. Among other things, Haswell processors will probably implement some performance improvements, the details of which will obviously become known later. According to the tick-tock principle, a reduction in the technical process to 14 nm is expected a year after the chip was introduced - this architecture will be called Broadwell.

In 2014, the company released the successor to the Haswell processor architecture, which is called Broadwell and uses the first truly integrated system-on-a-chip (SoC) design. Compared to its predecessor, Broadwell will receive some architectural changes. In addition to the actual SoC design, there are Ethernet, Thunderbolt or USB 3.0 controllers on the die. The graphics core is also inherited from Haswell, will have support for DirectX 11.1 and image output in resolutions up to 4K. Like Haswell, the processor uses the same 947-pin pad for mobile and the LGA 1150 for desktop, which means the Intel platform is compatible with two generations of processors.

Socket LGA 1151.

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, which are still actively used and supported by new processors. In this article, we have compiled the most popular Intel processor sockets 2017 that can still be supported.

What is a socket?

Before we move on to examining processor skeletons, let's try to understand what a socket is? 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 new set of pins, which means a new socket appears. However, in some cases, processors retain compatibility with previous generations of Intel processors. The socket is located on the motherboard and cannot be upgraded without completely replacing the board. Therefore, upgrading the processor may require a complete reassembly of the computer. Therefore, it is important to know which socket is used in your system and what can be done 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 processors, Kaby Lake have not 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. From 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 still a few percent faster.

3. LGA 1155

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

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 update 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.

4. LGA 2011

The LGA 2011 socket was released in 2011 after the LGA 1155 as a socket for the high-end Sandy Bridge-E / EP and Ivy Bridge E / EP processors. The socket is designed for six core processors and for all processors in the Xenon line. For home users, the X79 motherboard will be relevant. All other boards are designed for corporate users and Xenon processors.

In the tests, the Sandy Bridge-E and Ivy Bridge-E processors show pretty good results, the performance is 10-15% higher.

Supported processors:

• Haswell-E Core i7 - 5820K, 5930K, 5960X;

• Sandy Bridge-E Core i7 - 3820, 3930K, 3960X, 3970X.

These were all modern intel processor sockets.

5. LGA 775

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 have been completely forgotten, but are still found in users' computers.

The latest socket is intel 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.

Sockets of any processor originate from a socket for microcircuits, being, in fact, microcircuits for the logical execution of program codes. The first processors did not differ in design from other microelectronic devices and at first did not have a slot for installation and were soldered directly onto a printed circuit board, also known as - motherboard.

Consider all the Intel processors created to date and the sockets for them that have gone into production:

The history of sockets before the creation of mainstream personal computers

DIP socket- had a standard version for a 40-pin microcircuit design, suitable not only for early Intel processors, but also for various microcircuits of that time. Used by Intel eight bit processors since 1970 8008 , 8080 and 8085 ... Speed ​​characteristics - 5-10 MHz. PLCC socket- the beginning of its use around 1978, the socket becomes the prototype of all executable sockets for processors. The socket is made in the form of a recessed square, the sockets of the processor legs are made along the edges of the socket. Used by 32-bit series processors 80186 , 80286 , 80386 since 1982. Speed ​​characteristics - 6-40 MHz.

The first personal computers

Socket 1- with the release of this socket in 1989, the era of processors made in PGA form factor... The socket had a square design with sockets for multiple processor legs. The processors had 169 pins to the motherboard and were the first mainstream personal computer processors. Socket used by series processors 80486DX, 80486GX, 80486SX, 80486SL, 80486DX2, 80486DX4... Speed ​​characteristics - 16-33 MHz.

Socket 2- was a continuation of the development of sockets for processors. The socket was used at the same time as Socket 1, but it had more contacts - 238. Processors were used of the same series, the speed characteristics increased - 25-83 MHz.

Socket 3- was created for interface processors based on the 486 series of processors. The socket is also used by AMD processors of the 486 series, the speed characteristics do not change 25-83 MHz.

The first computers of world distribution

Socket 4- the first socket for series processors Pentium 1, supported the functions of overclocking and replacement, the processors worked on the bus from 60 to 66 MHz, which accordingly made it possible for the first Pentiums to have speed characteristics of 120-133 MHz. Supported installation of 273 pin processors since 1993.

Socket 5- continued the development of Intel processors and was made to work on the system bus from 50 to 66 MHz, and supported the installation of 320-pin processors Intel Pentium 1... Also, third-party processors were produced for it. We can say that it was the first standard socket for processors up to 300 MHz.

Socket 6- slightly modified Socket 3, due to the late release for the 486 series processors, is poorly known in the market. It had a 235-pin socket for the processor. Speed ​​characteristics up to 166 MHz.

The first fully multimedia computers

Socket 7- the most common socket for all processors up to 300 MHz, meaning that, based on the Intel Pentium 1 terminology, it ended up using the fifth generation technology at 300 MHz. Had a performance for 321 contacts. Supported processors Pentium MMX and Intel Pentium, and third-party processors. Produced since 1994.

Socket 8- designed specifically for the processor Intel Pentium PRO and processor Intel Pentium 2 OverDrive, had 387 pin sockets for the processor and was made in a rectangular form factor. The speed characteristics of the processors used are up to 333 MHz. Introduced in 1995, the production of the socket was discontinued in favor of the Slot 1 connector. Socket SLOT 1- to use all the capabilities of the processor Intel Pentium II and further Intel Pentium 3, the main feature is the increased processor cache taken out from the processor core, processors are created, implemented on a printed circuit board with 242 edge contacts, another contact name SC242... The production of the connector started in 1997. Supported processors Intel Pentium 2 and Intel Pentium III as well as third party processors. An adapter for processors has been released Socket 370, the processors were inserted into an adapter, which, in turn, was docked with SLOT 1. Speed ​​characteristics from 233 to 1200 MHz. SLOT 2 slot- designed for server and multitasking solutions using Intel Pentium 2 and Intel Pentium 3 Xeon series, unlike SLOT 1 it supported the second cache level up to 2 Megabytes. Something remotely resembled the SLOT 1 connector but had 330 pins. Speed ​​characteristics from 400 to 100 MHz.

The era of modern computers

Socket 370- the most common socket for Intel processors. It is with him that the era of division of Intel processors into inexpensive solutions begins. Celeron with a trimmed cache and Pentium- more expensive full versions of the company's product. The connector was installed on motherboards with a system bus from 60 to 133 MHz, The socket is made in the form of a plastic movable box of a square design, when a processor with 370 contacts was installed, a special plastic lever pressed the processor legs to the connector pins. Supported processors Intel Celeron Coppermine, Intel Celeron Tualatin, Intel Celeron Mendocino, Intel Pentium Tualatin, Intel Pentium Coppermine... The speed characteristics of the installed processors are from 300 to 1400 MHz. Supported 3rd party processors. Produced since 1999.

Socket 423- the first socket for processors Pentium 4... It had 423-pin mesh legs, was used on motherboards of personal computers. It existed for less than a year, due to the impossibility of the processor to further increase in frequency, the processor could not pass the frequency of 2 GHz. Replaced by Socket 478. Beginning of production in 2000.

Socket 478- released in pursuit of a competitor's connector (AMD) Socket A, as the previous processors failed to raise the 2 GHz bar, and AMD took the lead in the processor market. The connector supports Intel solutions - Intel Pentium 4, Intel Celeron, Celeron D, Intel Pentium 4 Extreme Edition... Speed ​​characteristics from 1400 MHz to 3.4 GHz. Produced since 2000. Socket 495- connector for a mobile solution from Intel. Had 495 contacts and supported Intel Celeron processor series. Speed ​​characteristics 450 - 900 MHz. Produced since 2000.

It was carried out on a printed circuit board and had, respectively, 418 edge contacts. Speed ​​characteristics up to 800MHz. Produced since 2001.

Socket 603 Is the next server connector from Intel for the Xeon series. Socket 603 processor could be installed in Socket 604... Made in a square form factor, it had 603 sockets for processor legs. The speed characteristics of the installed processors are from 1400 MHz to 3 GHz. Produced since 2001.

Socket PAC611- is a 611-pin microprocessor socket for installation on processor motherboards Intel Itanium 2... The speed characteristics of the installed processors are 800-1000 MHz. Produced since 2002.

Socket 604- intended for server platforms and workstations, continuation of Socket 603. Made in 604-pin design. Designed for Intel Xeon E7xxx series processors, motherboards with this socket used a bus from 400 to 1066 MHz. Produced since 2002. Speed ​​characteristics from 1600 MHz to 3800 MHz. Socket 479- intended for use in mobile solutions, has 479 pin sockets for Intel processors. Although the destination was mobile computers, it was used in desktop solutions. Pentium M processor, having a version for this socket had 478 pin pins. The rest of the processors for the given socket are - Pentium III M released in 2001, Pentium M and Celeron M version 3xxx and later compatible socket processors. Produced since 2003. Speed ​​characteristics from 400 MHz and above.

Today's computers

Socket 775 or Socket T- the first connector for Intel processors without sockets, is made in a square form factor with protruding contacts. The processor was installed on protruding contacts, the pressure plate was lowered, and with the help of a lever it was pressed against the contacts. It is still used in many personal computers. Designed to work with virtually all 4th generation Intel processors - Pentium 4, Pentium 4 Extreme Edition, Celeron D, Pentium Dual-Core, Pentium D, Core 2 Quad, Core 2 duo and Xeon series processors.

Processor socket on the motherboard - this term refers to the connector where the computer processor located on the system board is inserted. I am sure that many readers have owned a desktop PC for many years. And often there is such a situation when at first a computer is bought purely for editing documents, sending letters and watching films. But as you study the capabilities of a PC, more and more programs are installed, new prospects for its use open up and, as a result, its power begins to be sorely lacking.

One of the significant steps towards its modernization is the replacement of the processor with a more efficient one. However, several problems arise here, one of which is the connector on the motherboard into which the processor is inserted - the socket. There are a huge number of them, so if you just go to the store and choose a more powerful "kernel" for your computer, then 99% that it will not be able to work with the installed motherboard, since when choosing it, you must take into account which socket it is for. made. And modern processors cost from a couple to tens of thousands of rubles - it's a pity to throw that kind of money down the drain!

I think that you have already understood the seriousness of the error. Now let's take a closer look at what they are and which socket to choose.

Like any high-tech equipment and components, sockets are constantly being upgraded, resulting in ever newer and more productive standards. However, this happens very often, as a result of which you can find both motherboards with old connectors and new ones on the market. And another picture is also observed - due to a quick update, you may not be able to select a processor that works with your motherboard socket for a 3-5 year old computer, or vice versa. Therefore, when choosing components for a new computer, it is also important to navigate the varieties of sockets in order to choose a motherboard model with the newest for the future.

Today, processors are produced by two competing firms - Intel and AMD, each of which produces its own socket standards. Any motherboard works with one of these companies and contains one of the types of sockets for processors from these manufacturers.

It looks like a rectangular pad with many contacts and a latch that holds the processor. Also around it there are several through holes in the board, into which the processor cooling system is attached, or a special plastic mount around it.

Intel processor sockets

• Obsolete - LGA 775, 1156, 1366, 2011
• Modern - LGA 1151, 1150, 1155

The number in the socket name indicates the number of pins on the surface.

AMD processor sockets

• Deprecated - AM2, AM2 +
• Modern - AM3, AM3 +, FM1, FM2

It is very easy to visually distinguish between modern sockets of Intel processors from AMD:

1. Firstly, on the motherboard connector for AMD, there are many holes for pins, which are in the form of pins on the processor. On the other hand, on Intel sockets, the pins themselves are pins, but in the processor there are holes.
2. There is also a difference in the fastening of the processor - the Intel socket has a metal frame around the perimeter with a locking latch. AMD processors are secured by offsetting the top plate of the socket relative to the bottom.
3. And finally, the cooler (fan) for Intel is mounted in the holes mentioned above, and for AMD on a special plastic frame around the socket. All these differences can be seen in the screenshot below.

In addition, AMD has prudently made some sockets compatible between lower and older models of the same generation. So, on the socket of the AM3 + motherboard, you can install a processor with both an older AM3 and AM3 +. But this does not always work, so you must first look at the compatibility on the manufacturer's website.

In the description of the motherboard and processor, the socket can be denoted in different ways, for example: "Socket", "S" or just the model number.

Consider, for example, a motherboard with an Intel socket and a processor from AMD.

This screenshot shows a board with socket 1155, which is clearly indicated by the name:
"ASRock H61M-DGS (RTL) LGA1155 PCI-E + Dsub DVI + GbLAN SATA MicroATX 2DDR-III"

And here is a page with an AMD processor with socket FM 2, which is also evident from the name:
"ASUS F2A85-V PRO (RTL) SocketFM2 3xPCI-E + Dsub + DVI + HDMI + DP + GbLAN SATA RAID ATX 4DDR-III"

Also, the socket model is often mentioned in the descriptions of coolers in order to clarify which socket it can be installed on. For example, in the example below from the title, we immediately understand which sockets this cooler will work with (Intel 775, 1155 and AMD AM2, AM3):
Cooler Master Buran T2 (3pin, 775/1155 / AM2 / AM3, 30 dB, 2200 rpm, temp.)

When upgrading an old computer

For example, if the processor is burnt out or you want to install a more efficient one. Or vice versa, the motherboard is out of order and you want to buy a new one for the old processor. In any of these cases, in addition to accounting, it is necessary to determine the motherboard model and look at the manufacturer's website which socket it uses.

We open the lid of the computer and look for an inscription on the motherboard indicating its model. As a rule, it is available, for example in the following image we see the GA-870A-UD3 model from the manufacturer Gygabite.

We go to the company's website or simply drive this model into a search engine and look at a detailed description of the board, namely with which specific processor models and which socket it interfaces with.

In our example, these are AMD Phenom II or AMD Athlon II processors with socket AM3 - we go to the store and take one of them.

Building a computer from scratch

The second case when this information can come in handy is when you assemble your computer from scratch yourself. After you decide on you need to choose a processor with exactly the socket that is installed on it. Some sites have a very convenient function for automatic filtering of processors suitable for a specific board.

If we are talking about replacing the board, then accordingly it is necessary to choose such that it contains an identical socket and supports work with these processors.

Replacing the cooling system

Finally, the socket model should be considered when you want to change the processor fan or install a more powerful cooling system. The parameters of these devices also indicate which sockets they can be installed on (for example, boxed coolers from AMD processors cannot be installed on an Intel socket).

Today this is where I finish the article, I hope this information will be useful to you when choosing the best socket on the motherboard for the processor! Well, for a snack, according to the tradition of the video, how to properly install the processor into the socket.

Processor socket- connector, a place on the computer where the processor is inserted. The processor, before it is installed in the motherboard, must match its socket. It's like a socket and a contact plug - needless to say that a euro-plug will not fit a simple Soviet socket.

Usually, in computer stores, next to each processor, you can see a plate listing its main characteristics. So the processor socket is almost the most important characteristic, and it is on it that you first need to pay attention when buying a new processor. Because it may happen that the processor does not fit the computer's motherboard precisely because of the socket.

Just imagine - you came to a computer store, chose a processor there, paid money for it and came home happy, start installing it - and it DOES NOT FIT! You drop everything, run back to the store, hoping to return this processor back and thereby correct the situation, come running, and they tell you - "this is not a warranty case, you had to look more carefully when you bought it." Well, okay, it was a small lyrical digression. Now let's talk specifically about these same sockets.

The whole variety of sockets can be divided into two large groups:

1. Intel processor sockets.
2. AMD processor sockets.

Below are photographs of the sockets of both processor companies.

In this photo, you can see that the pins are sticking out of the socket on the motherboard.

And in this photo, on the contrary, you can see the grooves for these contacts, and they themselves are located directly on the processor.

Let's see what is so drastic sockets differ physically from each other:

• Number of contacts
• By the type of these same contacts
• Distance of fasteners for CPU coolers
• The actual size of the socket itself

Number of contacts - there can be 400, 500, 1000 and even more. How to find out? The socket marking already contains all the information. For example, an Intel Pentium 4 processor has an LGA 775 socket. So 775 is just the number of pins, and LGA means that the processor does not have pins, they are located in the motherboard socket.

Type of contacts - everything is clear here, either "pins" or contacts without pins. No other, as they say, is given.

Now about the distances between the mounts for CPU coolers. The fact is that these distances are different for each socket, and you also need to pay special attention to this. Although there are do-it-yourself methods, when a cooler from one socket is attached to another socket using skillful hands and something else.

These were all physical differences, now let's talk about how the sockets differ from each other so technologically. A technologically, sockets differ from each other:

• The presence of various additional controllers
• The presence or absence of support for graphics integrated into the processor (graphics processor core)
• Higher performance parameters

What else does the processor soket affect?

In addition to what has already been written here, processor socket also affects the size of the processor itself. Generally speaking, to put it very briefly, the processor socket affects which processor will be installed in it. Everything else (for example, what will be written here further in the text) depends on the processor, but we all know that the processor and the socket are two inseparable concepts. Therefore, all those parameters that depend on the processor (or that are influenced by the processor) also depend on the socket of this processor.

Perhaps, I will give a few more points that the processor (or its socket) has the ability to influence, in other words - the processor or its socket affects:

• Supported RAM type
• FSB bus frequency
• Indirectly (mostly by the chipset) to the PCI-e slot version
• Per version (also indirectly)

What is a socket for?

The fact is that manufacturers of modern motherboards deliberately left us the opportunity to change various devices, including the processor. This is where such a concept as a socket appears, because from the point of view of manufacturers, it would be quite possible to solder the processor directly to the mat. board, and in terms of reliability, it is more expedient. But this was done, frankly, on purpose - i.e. for a possible upgrade of the system. In other words, we wanted to replace the processor with another - we pulled it out of the socket and inserted the one we need, of course with the amendment that it must have the same socket as the old processor. In truth, it is for the possible modernization of computer hardware that the vast majority of slots and connectors exist on the motherboard.

Now let's talk about socket support for various processors. Below is a table with popular (at the time of publication of the material) sockets and their corresponding processors:

Socket	CPU
LGA 775 (Socket T), launched in 2004	Intel Pentium 4 Pentium 4 Extreme Edition Intel Celeron D Pentium D Pentium Extreme Edition Pentium Dual-Core Core 2 duo Core 2 extreme Core 2 Quad Xeon (for servers)

Socket FM1, the year of the beginning of release - 2011	All processors with microarchitecture AMD Fusion
Socket FM2, launched in 2012	All processors with microarchitecture Bulldozer

And in conclusion - a small recommendation for those who are going to buy a new processor: before buying, always check the compatibility of the motherboard socket and the processor. For example, if the motherboard has an LGA775 socket, take processors that are made specifically for this socket, no other processors will work.
