What determines the number (type) of the LGA processor socket? Processor sockets, what is a processor socket

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

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

Before we look at processor sockets, let's try to understand what they are. A socket is the physical interface connecting the processor to the motherboard. The LGA socket consists of a series of pins that align with the plates on the underside of the processor.

New processors usually need a different set of pins, which means a new socket. However, in some cases, processors remain compatible with 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 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 generation of processors. These processors used the 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 brought the following boards: B250, Q250, H270, Q270, Z270.

Compared to the previous version of LGA 1150, USB 3.0 support has appeared here, the operation of DDR4 and DIMM memory modules has been optimized, and SATA 3.0 support has been added. DDR3 compatibility was still maintained. For 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 want to overclock the processor or memory, you will have to choose a higher-end chipset. In addition, support for Intel Active Management, Trusted Execution, VT-D and Vpro has been added.

In tests, Skylake processors show better results than Sandy Bridge, and the new Kaby Lake is even several percent faster.

Here are the processors that are currently running on this socket:

SkyLake:

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 Sandy Bridge architecture processors 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 senior line includes B65, H61, Q67, H67, P67 and Z68. All of them were released along with the release of Sandy Bridge. The launch of Ivy Bridge brought the B75, Q75, Q77, H77, Z75 and Z77. All boards have the same socket, but some features are disabled on budget devices.

Supported processors:

4. LGA 2011

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

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

Supported processors:

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

conclusions

In this article, we looked at 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 on users’ computers.

Latest Intel socket 1151, supported by Skylake and KabyLake processors. We can assume that the CoffeLake processors that will be released this summer will also use this socket. There used to be other types of Intel sockets, but they are no longer very common.

Socket (colloquial - socket) of the central processor is a connector located on the computer motherboard to which the central processor is connected. The processor, before it is installed on the motherboard, must fit its socket. It is very easy to understand what a processor socket is, if you remember that the latter is a microcircuit, only of relatively large size. The socket is located on the motherboard and looks like a low rectangular structure with many holes, the number of which corresponds to the processor legs. To securely fix the inserted microcircuit in the socket, a specially designed mechanical latch is used. Note that Intel, unlike AMD, has recently been using a different principle of connecting the processor and board.

Sometimes on forums the question is asked about which socket to choose. In fact, you should first select a processor, and then a board with the appropriate socket for it. However, one important point must be taken into account. Intel is famous for the fact that often each new generation of processors involves the use of a new socket. This may lead to the fact that a recently purchased computer based on a processor from this company will be difficult to upgrade in a few years due to the incompatibility of the installed microprocessor and new ones offered on the market. AMD has a more loyal attitude towards customers: changing sockets occurs more slowly, and backward compatibility is usually maintained. Although, times are changing.

• Socket 370 – the most common socket for Intel processors. It is with this that the era of dividing Intel processors into inexpensive Celeron solutions with a trimmed cache and Pentium – more expensive full versions of the company’s product – begins. The connector was installed on motherboards with a system bus from 60 to 133 MHz. The socket is made in the form of a square plastic movable box; when installing a processor with 370 contacts, a special plastic lever presses the processor legs to the connector contacts. Supported processors Intel Celeron Coppermine, Intel Celeron Tualatin, Intel Celeron Mendocino, Intel Pentium Tualatin, Intel Pentium Coppermine. Speed ​​characteristics of installed processors from 300 to 1400 MHz. Supported third party processors. Produced since 1999.
• Socket 423 – the first connector for Pentium 4 processors. It had a 423-pin grid of legs and was used on motherboards of personal computers. It existed for less than a year, due to the inability of the processor to further increase in frequency, the processor could not pass the frequency of 2 GHz. Replaced by Socket 478 connector. Production began in 2000.

• Socket 478 - released in pursuit of the competitor (AMD company) Socket A, since previous processors were unable to raise the bar of 2 Gigahertz, and AMD took the lead in the processor production 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 754 was developed specifically for the Athlon 64 processor. The release of new processor sockets was associated with the need to replace the Athlon XP processor line, which was based on Socket A. The first processors of AMD K8 platforms were installed in Socket 754 processor sockets measuring 4 by 4 centimeters. This need was dictated by the fact that the Athlon 64 processors had a new bus and integrated memory controllers. The voltage output from this socket was 1.5 volts. Of course, the 754 became an intermediate stage in the development of the Athlon 64. The high cost and initial shortage of these processors did not make this platform very popular. And by the time the availability and cost of components had just returned to normal, AMD presented the release of a new socket - Socket 939. By the way, it was he who helped make the Athlon 64 a popular and truly affordable processor.

• Socket 775 or Socket T - the first connector for Intel processors without sockets, made in a square form factor with protruding contacts. The processor was installed on the protruding contacts, the pressure plate was lowered, and using a lever it was pressed against the contacts. Still used in many personal computers. Designed to work with almost all fourth 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. Produced since 2004. Speed ​​characteristics of installed processors range from 1400 MHz to 3800 MHz.

Socket A. This connector is known as Socket 462 and is a socket for processors from Athlon Thunderbird to Athlon XP/MP 3200+, as well as for AMD processors such as Sempron and Duron. The design is made in the form of a ZIF socket with 453 working contacts (9 contacts are blocked, but despite this, the number 462 is used in the name). The system bus for Sempron, XP Athlon has a frequency of 133 MHz, 166 MHz and 200 MHz. The weight of coolers for Socket A, recommended by AMD, should not exceed 300 grams. The use of heavier coolers can lead to mechanical damage and even lead to failure of the processor power system. Processors with a frequency of 600 MHz (for example, Duron) and up to 2300 MHz (meaning the Athlon XP 3400+, which never went on sale) are supported.

• Socket 939 , containing 939 contacts with an extremely small diameter, making them quite soft. This is a "simplified" version of the previous Socket 940, usually used in high-performance computers and servers. The absence of one hole in the socket did not make it possible to install more expensive processors into it. This connector was considered very successful for its time, as it combined good capabilities, dual-channel memory access and low cost of both the socket itself and the controller on computer motherboards. These connectors were used for computers with conventional DDR memory. Immediately after the transition to DDR2 memory, they became obsolete and gave way to AM2 connectors. The next step is the invention of new DDR3 memory and new AM2+ and AM3 sockets designed for the next models of AMD quad-core processors.

LGA 1366 socket – Made in 1366 contact form, produced since 2008. Supports Intel processors – Core i7 series 9xx, Xeon series 35xx to 56xx, Celeron P1053. WITH speed characteristics from 1600 MHz to 3500 MHz. Core i7 and Xeon (35xx, 36xx, 55xx, 56xx series) with integrated three-channel memory controller and QuickPath connection. Replacement of Socket T and Socket J (2008)

• Socket AM2 (Socket M2), developed by AMD for certain types of desktop processors (Athlon-LE, Athlon 64, Athlon 64 FX, Athlon 64 X2, Sempron-LE and Sempron, Phenom X4 and Phenom X3, Opteron). It replaced Socket 939 and 754. Despite the fact that Socket M2 has 940 pins, this socket is not compatible with Socket 940, since the older version of Socket 940 cannot support dual-channel DDR2 RAM. The first processors to support Socket AM2 were single-core models Orleans (or the 64th Athlon) and Manila (Sempron), some dual-core Windsor (for example, Athlon 64, X2 FX) and Brisbane (AthlonX2 and Athlon 64X2). In addition, Socket AM2 includes Socket F, designed for servers, and a Socket S1 variant for various mobile computers. Socket AM2+ i is absolutely identical in appearance to the previous one, the only difference is the support for processors with Agena and Toliman cores.

• LGA 1156 socket – Made using 1156 protruding contacts. Produced since 2009. Designed for modern Intel processors for personal computers. Speed ​​characteristics from 2.1 GHz and higher.

• LGA 1155 socket or Socket H2 - designed to replace the LGA 1156 socket. Supports the latest Sandy Bridge processor and the future Ivy Bridge. The connector is made in 1155-pin design. Produced since 2011. Speed ​​characteristics up to 20 GB/s.
• Socket R (LGA2011) - Core i7 and Xeon with integrated quad-channel memory controller and two QuickPath connections. Replacement Socket B (LGA1366)

• Socket FM1 is AMD's platform for Llano processors and looks like a tempting proposition for those who love integrated systems.

Socket AM3 is a processor socket for a desktop processor, which is a further development of the Socket AM2+ model. This connector has support for DDR3 memory, as well as higher speeds for HyperTransport buses. The first processors to use this socket were the Phenom II X3 710-20 and Phenom II X4 models 805, 910 and 810.

Socket AM3 + (Socket 942) is a modification of Socket AM3, developed for processors codenamed “Zambezi” (microarchitecture - Bulldozer). Some socket AM3 motherboards will allow you to update the BIOS to use socket AM3+ processors. But when using AM3+ processors on AM3 motherboards, it may not be possible to obtain data from the temperature sensor on the processor. Also, the power saving mode may not work due to the lack of support for fast core voltage switching in the Socket AM3 version. The AM3+ socket on motherboards is black, while the AM3 is white. The diameter of the holes for the pins of processors with Socket AM3 + exceeds the diameter of the holes for the pins of processors with Socket AM3 - 0.51 mm versus the previous 0.45 mm.

• Socket H3 or LGA 1150 is a processor socket for Intel processors of the Haswell (and its successor Broadwell) microarchitecture, released in 2013. LGA 1150 is designed as a replacement for LGA 1155 (Socket H2). Made using LGA (Land Grid Array) technology. It is a connector with spring-loaded or soft contacts, to which the processor is pressed using a special holder with a grip and a lever. It is officially confirmed that the LGA 1150 socket will be used with Intel Q85, Q87, H87, Z87, B85 chipsets. The mounting holes for cooling systems on sockets 1150/1155/1156 are completely identical, which means full comprehensive compatibility and identical installation procedures for cooling systems for these sockets.
• Socket B2 (LGA1356) - Core i7 and Xeon with integrated three-channel memory controller and QuickPath connections. Replacement Socket B (LGA1366)
• FM2 connector - Processor socket for hybrid processors (APU) from AMD with the Piledriver core architecture: Trinity and Komodo, as well as the canceled Sepang and Terramar (MCM - multi-chip module). Structurally, it is a ZIF connector with 904 pins, which is designed for installing processors in PGA-type cases. The FM2 connector was introduced in 2012, just a year after the FM1 connector. Although socket FM2 is an evolution of socket FM1, it is not backward compatible with it. Trinity processors have up to 4 cores, Komodo and Sepang server chips have up to 10, and Terramar have up to 20 cores.

• LGA 1151 socket - a socket for Intel processors that supports Skylake architecture processors. LGA 1151 is designed as a replacement for LGA 1150 (also known as Socket H3). LGA 1151 has 1151 spring-loaded contacts to contact the processor pads. According to rumors and leaked Intel advertising documentation, motherboards with this socket will feature DDR4 memory support. All Skylake architecture chipsets support Intel Rapid Storage Technology, Intel Clear Video Technology and Intel Wireless Display Technology (when supported by the processor). Most motherboards support various video outputs (VGA, DVI or - depending on the model).

• LGA 2066 (Socket R4) is a socket for Intel processors that supports Skylake-X and Kaby Lake-X processors without an integrated graphics core. Designed to replace the LGA 2011/2011-3 (Socket R/R3) socket for high-end Basin Falls desktops (X299 chipset), while the LGA 3647 (Socket P) will replace the LGA 2011-1/2011- 3 (Socket R2/R3) in server platforms based on Skylake-EX (Xeon “Purley”).
• AM4 (PGA or µOPGA1331) is a socket manufactured by AMD for microprocessors with Zen microarchitecture (Ryzen brand) and subsequent ones. The connector is a PGA (pin grid array) type and has 1331 contacts. It will be the company's first socket with support for the DDR4 memory standard and will be a single socket for both high-performance processors without an integrated video core (currently using Socket AM3+), and for low-cost processors and APUs (previously using various sockets of the AM / FM series).
• Socket TR4 (Socket Ryzen Threadripper 4, also Socket SP3r2) is a type of connector from AMD for the Ryzen Threadripper family of microprocessors, introduced on August 10, 2017. Physically very close to the AMD Socket SP3 server connector, however, it is incompatible with it. Socket TR4 became the first LGA-type socket for consumer products (previously LGA was used in the server segment, and processors for home computers were produced in FC-PGA packages). It uses a complex multi-stage process of mounting the processor into the socket using special holding frames: an internal one, secured with latches to the cover of the chip case, and an external one, secured with screws to the socket. Journalists note the very large physical size of the connector and socket, calling it the largest format for consumer processors. Due to its size, it requires specialized cooling systems that can handle up to 180W. The socket supports HEDT (High-End Desktop) segment processors with 8-16 cores and provides the ability to connect RAM via 4 DDR4 SDRAM channels. The socket has 64 generation 3 PCIexpress lanes (4 are used for the chipset), several 3.1 and SATA channels

During the upgrade process or when configuring a new system unit, one of the main factors for its successful assembly is the correctly selected and compatible components. To achieve this, manufacturers have introduced certain standards for the compatibility of these same components.

For example, when replacing a central processor, there is a different designation (CPU), it is very important to understand exactly what type of socket it has and whether it will fit the connector on the motherboard of a personal computer.

What it is

The main and very important parameter of the motherboard is the central processor socket (CPU socket). This is a socket located on the main board of the computer, intended for installing a CPU into it. And before connecting these components into one coherent system, you need to determine whether they are compatible with each other or not. It's like plugging a plug into a socket., if the plug is American standard and the socket is European, then naturally they will not fit together and the device will not work.

As a rule, in retail outlets selling computer components, in the price tag on the window or in the price list, the main parameters of the processor that is being sold are always indicated. Among these parameters, the type of socket to which this processor is suitable is indicated. The main thing when buying is to take into account this primary characteristic of the CPU.

This is important because when installing the processor into the motherboard socket, if you choose the wrong socket, it simply will not fit into its place. In the huge selection of connectors that exists today, there are two main types:

• Sockets for central processors from the manufacturer AMD.
• Sockets designed for processors manufactured by Intel.

Intel and AMD socket specifications

• Physical dimensions of socket.
• The method of connecting the contacts of the socket and the processor.
• Type of mounting of the CPU cooler cooling system.
• The number of sockets or contact pads.

Connection method - there is nothing complicated here. The socket has either sockets (like AMD) into which the processor contacts are inserted. Either pins(like Intel), on which the flat contact pads of the CPU rest. There is no third option here.

The number of sockets or pins - there are many options here, their number can range from 400 to 2000, and maybe even more. You can determine this parameter by looking at the marking of the socket in the name of which this information is encoded. For example, the Intel Core i7-2600 for the Intel LGA 1155 processor socket has exactly 1155 contact pads on its surface. The abbreviation LGA means that the processor has flat contacts, and the socket, on the contrary, consists of 1155 pins.

Well, the mounting methods for the CPU cooling system may differ: in the distance between the holes on the motherboard designed to secure the lower part of the cooling system. And the method of fixing the upper half, consisting of a radiator and cooler. There are also exotic cooling options made at home, or systems with a water method of lowering the CPU temperature.

There are other characteristics that are directly related to the functionality of the entire motherboard and its performance. The presence of a socket of a certain standard also indicates what possible parameters are included in this platform and how modern this motherboard is. Here are some features that distinguish a board built on a specific socket and a chipset developed for it:

• Processor clock speed range, number of supported cores and data transfer speed.
• The presence of controllers on the motherboard that expand the functionality of the board.
• Support or presence of a built-in graphics adapter in the motherboard or main processor.

How to determine the socket of a processor

The main component that performs the main task in the operation of a computer is the CPU. And if it fails, then there is nothing left to do but replace it with an analogue similar in connector and characteristics . This is where the challenge arises by determining the socket type. There are many options to find out, and here are three main and available ones.

By manufacturer and model

An easy method using access to the World Wide Web (i.e., via the Internet). All the necessary data on products produced by a particular motherboard manufacturing company is available on the manufacturers’ official websites. The information is not hidden anywhere and can be studied by anyone. You just have to enter the data you need for this into the search bar.

Here is an approximate sequence of actions:

Via Speccy

1. Download and install the Aida64 or Speccy application on your computer. Next, let's consider the second option. Open the Speccy program. And find in it the section with CPU parameters, it should be called “Central Processor”.
2. Next, in the selected section, find the line called “Constructive” and read its contents. This is where the type of processor socket will be indicated.
3. Approximately the same steps will need to be performed when using the Aida64 program. Section “Computer”, subsection DMI, then in the subsection “Processor”, look for a line with the word Socket.

In the documentation

This method is the easiest, but requires documentation attached to the system unit upon purchase. Among the many instructions for the motherboard, processor, video adapter and other components from which the computer is assembled, those intended for the CPU and motherboard are suitable. Carefully scroll through the entire manual and look in it for the words: connector, socket type. This is where information about the socket standard of the motherboard or processor should be.

A personal computer is not a cheap thing, and in some versions it can even cost as much as an old used car. And change it very often- it's a pretty unprofitable business. Even reputable and successful companies do this relatively rarely. But, despite this, from time to time you still have to upgrade and speed up the computing capabilities of any computer.

To do this, you have to disassemble the old hardware and find out information about certain characteristics and parameters. However, you need to take into account your abilities for such procedures. Here, as people say: “If you can’t, don’t bother.” And if there is uncertainty about the success of such an event, then it is better to contact special service centers or individual experienced craftsmen.

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

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

What is a socket?

Before we move on to considering processor sockets, let's try to understand what a socket is? A socket is the physical interface connecting the processor to the motherboard. The LGA socket consists of a series of pins that align with the plates on the underside of the processor.

New processors usually need a new set of pins, which means a new socket. However, in some cases, processors remain compatible with previous generations of Intel processors. The socket is located on the motherboard and cannot be updated without completely replacing the board. Therefore, upgrading 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 can be done with it.

1. LGA 1151

LGA 1151 is the latest Intel socket. It was released in 2015 for the Intel Skylake generation of processors. These processors used the 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 brought the following boards: B250, Q250, H270, Q270, Z270.

Compared to the previous version of LGA 1150, USB 3.0 support has appeared here, the operation of DDR4 and DIMM memory modules has been optimized, and SATA 3.0 support has been added. DDR3 compatibility was still maintained. 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 want to overclock the processor or memory, you will have to choose a higher-end chipset. In addition, support for Intel Active Management, Trusted Execution, VT-D and Vpro has been added.

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

Here are the processors that are currently running on this socket:

SkyLake:

• Pentium - G4400, G4500, G4520;
• Core i3 - 6100, 6100T, 6300, 6300T, 6320;

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 Sandy Bridge architecture processors 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 upgrade without changing the motherboard, just like now with Kaby Lake.

This socket is supported by twelve motherboards. The senior line includes B65, H61, Q67, H67, P67 and Z68. All of them were released along with the release of Sandy Bridge. The launch of Ivy Bridge brought the B75, Q75, Q77, H77, Z75 and Z77. All boards have the same socket, but some features are disabled on budget devices.

Supported processors:

Ivy Bridge

• Celeron - G1610, G1610T, G1620, G1620T, G1630;

4. LGA 2011

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

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

Supported processors:

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

conclusions

In this article, we looked at 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 have already been completely forgotten, but are still found in user computers.

Latest intel socket 1151, supported by Skylake and KabyLake processors. We can assume that the CoffeLake processors that will be released this summer will also use this socket. There used to be other types of intel sockets, but they are already very rare.

Many people, when assembling a PC, or when purchasing a ready-made solution based on a particular processor, are faced with the concept of “socket”. Let's guess: half have no idea what it is or what it is intended for. In this article we will look at what this term represents, as well as the main sockets of AMD processors.

The Reds have always been distinguished by a loyal policy regarding the replacement of processor sockets: maximum preservation of compatibility with obsolete chips, uniform fasteners for cooling systems (AM2-AM3+ generation), easy BIOS flashing and more. But how the company’s technologies developed is the topic of this article.

To put it very briefly, a socket is a special connector on the motherboard into which the CPU is inserted. This design is created as an alternative to soldering, which greatly simplifies chip replacement and system upgrades as a whole. The second advantage is the reduction in cost of MP production.

And now about the pulp. The socket “accepts” only a certain type of processor. In other words, the contact pad of various connectors is significantly different from each other. Moreover, the type of mounts for cooling systems also often differs, which makes almost all sockets incompatible with each other.

AMD processor sockets

We would like to present you with a list of the most current AMD processor sockets at the moment, as well as describe the supported technologies for each. The list will consist of the following candidates:

1. Socket AM4+;
2. Socket TR4;
3. Socket AM4;
4. Socket AM3+;
5. Socket AM3;
6. Socket AM2+;
7. Socket AM2.

Let's get to the educational program, gentlemen.

1.Socket AM4+

The AM4+ processor socket should theoretically debut in April 2018 to support 12nm Zen+ processors (but this is not certain). It is known that motherboards with this socket will support the new X470 chipsets, which indicates higher CPU overclocking to frequencies previously unattainable with the X370.

Additionally, there is support for XFR 2 and Precision Boost 2 technologies. A nice feature of the new product is full compatibility with all existing representatives of the Ryzen 1000 series. It will only be enough to update the UEFI-BIOS firmware.

There is no information about AMD processors on this socket yet.

2. Socket TR4

A completely new socket developed by AMD engineers in 2016 for Threadripper family processors and visually similar to SP3, but not compatible with Epyc models. The first LGA connector of its kind in “red” design for consumer systems (previously only PGA versions with “legs” were used).

Supports processors with 8-16 physical cores, 4-channel DDR4 memory and 64 PCI-E 3.0 lanes (4 of which are on the X399 chipset).

Processors running on this socket:

• Ryzen Threadripper 1950X (14 nm);
• Ryzen Threadripper 1920X (14 nm);
• Ryzen Threadripper 1900X (14 nm).

3. Socket AM4

A socket introduced by AMD in 2016 for microprocessors based on the Zen architecture (14 nm). It has 1331 pins for connecting the CPU and is the first connector from the company that supports DDR4 RAM. The manufacturer claims that this platform is unified for both high-performance systems without an integrated graphics core and future APUs. The socket is supported by the following motherboards: A320, B350, X370.

Among the main advantages, it is worth noting support for up to 24 PCI-E 3.0 lanes, up to 4 DDR4 3200 MHz modules in 2-channel mode, USB 3.0/3.1 (natively, not using third-party controllers), NVMe and SATA Express.

Processors running on this socket:

Summit Ridge (14 nm):

• Ryzen 7: 1800X, 1700X, 1700;
• Ryzen 5: 1600X, 1600, 1500X, 1400;
• Ryzen 3: 1300X, 1200.

• A-10: 9700;
• A-8: 9600;
• A-6: 9500, 9500E;
• Athlon: X4 950.

4. Socket AM3+

This socket is also called AMD Socket 942. It is essentially a modified AM3, developed exclusively for processors of the Zambezi family (i.e., the familiar FX-xxxx) in 2011. Backward compatible with the previous generation of chips by flashing and updating the BIOS (not supported on all MP models).

Visually different from its predecessor in the black color of the socket. Among the features worth noting is the memory management unit, support for up to 14 USB 2.0 and 6 SATA 3.0 ports. In parallel with the socket, 3 new chipsets were presented: 970, 990X and 990FX. Also available are the 760G, 770 and RX881.

Processors running on this socket:

Vishera (32 nm):

• FX-9xxx: 9590, 9370;
• FX-8xxx: 8370, 8370E, 8350, 8320, 8320E, 8310, 8300;

5. Socket AM3

A processor socket that first appeared on the market in 2008. Designed with low-cost to high-performance systems in mind. It is a further development of the AMD AM2 socket and differs from its predecessor, first of all, in support of DDR3 memory modules, as well as higher bandwidth of the HT (HyperTransport) bus. The socket is supported by the following motherboards: 890GX, 890FX, 880G, 870.

All processors released for socket AM3 are fully compatible with socket AM3+, when the latter only supports mechanical interaction (identical arrangement of PGA pins). To work on newer boards you will have to reflash the BIOS.

You can also install AM2/AM2+ family chips in the socket.

Processors running on this socket:

Sargas (45 nm):

• Athlon II: 170u, 160u;
• Sempron: 190, 180, 145, 140.

6. Socket AM2+

The AMD socket appeared in 2007. It is similar to its predecessor down to the smallest detail. Developed for processors built on Kuma, Agena and Toliman cores. All processors belonging to the K10 generation work perfectly on systems with an AM2 socket, but in this case you will have to come to terms with “cutting” the HT bus frequency to version 2.0, or even 1.0.

The socket is supported by the following motherboards: 790GX, 790FX, 790X, 770,760G.

Processors running on this socket:

Kuma (65 nm):

• Athlon X2: 7850, 7750, 7550, 7450, 6500.

Brisbane (45 nm):

• Athlon X2: 5000.

7. Socket AM2

It first debuted under the name M2 in 2006, but was hastily renamed to avoid confusion with Cyrix MII processors. Served as a planned replacement for amd 939 and 754 sockets. The socket is supported by the following motherboards: 740G, 690G, 690V.

As an innovation, it is worth noting support for DDR2 RAM. The first processors on this socket were single-core Orleans and Manila and dual-core Windsor and Brisbane.

Processors running on this socket:

Windsor (90 nm):

• Athlon 64: FX 62;
• Athlon 64 X2: 6400+, 6000+, 5600+, 5400+, 5000+, 4800+, 4600+, 4200+, 4000+, 3800+, 3600+.

Sparta (65 nm):

• Sempron LE: 1300. 1250, 1200, 1150, 1100.

Manila (90 nm):

• Sempron: 3800+, 3600+, 3400+, 3200+, 3000+, 2800+.

Results

AMD are such entertainers. Perhaps they themselves are surprised at the number of processor architectures that they have developed over their long history. It is noteworthy that the vast majority of older processors still work and pair perfectly with newer motherboards (if we are talking about the gap between sockets AM2 and AM3).

The most progressive connector at the moment, AM4, and its successor, AM4+, should receive support at least until 2020, which indicates potential backward compatibility of platforms with some minor limitations in functionality.
