Slot A is the physical and electrical specification for a 242-lead single-edge-connector used by early versions of AMD's Athlon processor. The Slot A connector allows for a higher bus rate than Socket 7 or Super Socket 7. Slot A motherboards use the EV6 bus protocol, a technology developed by Digital Equipment Corporation for its Alpha 21264 microprocessor. Slot A is mechanically compatible but electrically incompatible with Intel's Slot 1; as a consequence, Slot A motherboards were designed to have the connector's installed orientation be rotated 180 degrees relative to Slot 1 motherboards to discourage accidental insertion of a Slot 1 processor into a Slot A motherboard, vice versa. The choice to use the same mechanical connector as the Intel Slot 1 allowed motherboard manufacturers to keep costs down by stocking the same part for both Slot 1 and Slot A assemblies. Slot A was superseded by Socket A.

Socket F is a CPU socket designed by AMD for its Opteron line of CPUs released on August 15, 2006. In 2010 Socket F was replaced by Socket C32 for entry-level servers and Socket G34 for high-end servers; the socket employs a land grid array contact mechanism. Socket F is for use in AMD's server line and is considered to be in the same socket generation as Socket AM2, used for the Athlon 64 and Athlon 64 X2. Socket F is the base for the AMD Quad FX Platform, unveiled by AMD on November 30, 2006; this modified version of Socket F, named Socket 1207 FX by AMD, Socket L1 by NVIDIA, allows for dual-socket, dual-core processors in desktop PCs for home enthusiasts. All revisions except Socket Fr3 require the usage of registered DDR2 SDRAM. All revisions except Socket Fr1 require a dual-plane power-supply circuit for the CPU. Socket Fr1 Three HyperTransport 2.x links with 1 GHz, single-plane power-supply circuit Socket Fr2 Three HyperTransport 2.x links with 1 GHz, dual-plane power-supply circuit Socket Fr3 Three HyperTransport 2.x links with 1 GHz, unbuffered DDR2 SDRAM Socket Fr5 CPU: Three HyperTransport 3.x links with 2.2 GHz Motherboards: One HyperTransport 3.x link between CPU with 2.2 GHz, two HT 2.x links with 1 GHz for I/O operations Socket Fr6 Three Hypertransport 3.x links with 2.4 GHz, support for Snoop-Filter List of AMD Opteron microprocessors Tweakers.net: First benchmarks of Socket F Opterons in databasetest Tweakers.net: Pictures of the socket Dailytech: AMD's Next-gen Socket F Revealed PCstats: Socket F Near Term Roadmap
In computer hardware, a CPU socket or CPU slot contains one or more mechanical components providing mechanical and electrical connections between a microprocessor and a printed circuit board. This allows for replacing the central processing unit without soldering. Common sockets have retention clips that apply a constant force, which must be overcome when a device is inserted. For chips with a large number of pins, zero insertion force sockets are preferred. Common sockets include Land Grid Array; these designs apply a compression force once either a surface plate is put into place. This provides superior mechanical retention while avoiding the risk of bending pins when inserting the chip into the socket. Certain devices use Ball Grid Array sockets, although these require soldering and are not considered user replaceable. CPU sockets are used on the motherboard in server computers; because they allow easy swapping of components, they are used for prototyping new circuits. Laptops use surface-mount CPUs, which take up less space on the motherboard than a socketed part.
A CPU socket is made of plastic, comes with a lever or latch, with metal contacts for each of the pins or lands on the CPU. Many packages are keyed to ensure the proper insertion of the CPU. CPUs with a PGA package are inserted into the socket and, if included, the latch is closed. CPUs with an LGA package are inserted into the socket, the latch plate is flipped into position atop the CPU, the lever is lowered and locked into place, pressing the CPU's contacts against the socket's lands and ensuring a good connection, as well as increased mechanical stability.

The AMD Socket C32 is the server processor socket for AMD's current single-CPU and dual-CPU Opteron 4000 series CPUs. It is the successor to Socket AM3 for single-CPU servers and the successor for Socket F for lower-end dual-CPU servers. Socket C32 supports two DDR3 SDRAM channels, it is based on the Socket F and uses a similar 1207-land LGA socket but is not physically or electrically compatible with Socket F due to the use of DDR3 SDRAM instead of the DDR2 SDRAM that Socket F platforms use. Socket C32 was launched June 23, 2010 as part of the San Marino platform with the four and six-core Opteron 4100 "Lisbon" processors. Socket C32 supports the Bulldozer-based six- and eight-core "Valencia" Opterons introduced in November 2011. Like Socket G34, it uses the AMD SR5690, SR5670, SR5650 chipsets. Socket C32 is being used in the ultra-low-power Adelaide platform with the SR5650 chipset and HT1 interconnects instead of HT3.1.

Super Socket 7
The Super Socket 7 referred to as Super 7, is an extension of the Socket 7 ZIF socket specification. It features a 100 MHz front-side bus, support for AGP, a SPGA package. Super Socket 7 was used by AMD K6-2 and K6-III processors, some of the final Cyrix M-II processors, some of the final IDT WinChip 2 processors, Rise mP6 processors, it is backward compatible with Socket 7, meaning a Socket 7 CPU can be used with a Super Socket 7 motherboard, but a Super Socket 7 CPU cannot operate at full speed in a Socket 7 motherboard. Socket 5 CPUs are pin-compatible with Super Socket 7, but not all motherboards designed for Super Socket 7 supported the voltages needed for Socket 5 CPUs. While AMD had always used Intel sockets for their processors, Socket 7 was the last one for which AMD retained legal rights. Intel had hoped by discontinuing Socket 7 development and moving to Slot 1 that AMD would be left with an outdated platform, making their processors non-competitive. By extending the FSB from 66 to 100 MHz, Super Socket 7 gave AMD the stopgap solution they needed while developing their own independent motherboard infrastructure, Slot A.
While the architecture was cheap, served the intended purpose, many of the third party chipsets provided by VIA, SiS, others, were of low quality with regard to the AGP implementations. The reputation AMD gained for buggy, incompatible motherboards lingered, though an internal program by VIA to raise standards for their chipsets had begun to show results in the K6-III and Pentium III era, AMD put in place a quality assurance program for the Athlon processor.

Socket A is the CPU socket used for AMD processors ranging from the Athlon Thunderbird to the Athlon XP/MP 3200+, AMD budget processors including the Duron and Sempron. Socket A supports AMD Geode NX embedded processors; the socket is a zero insertion force pin grid array type with 462 pins. The front side bus frequencies supported for the AMD Athlon XP and Sempron are 133 MHz, 166 MHz, 200 MHz. Socket A supports 32-bit CPUs only. Socket A was replaced by Socket 754 and Socket 939 during 2003 and 2004 except for its use with Geode NX processors. Support of processor clock-speeds between 600 MHz to 2333 MHz Double data rate 100, 133, 166 and 200 MHz front side bus on Duron, XP and Sempron processors, based on the Alpha 21264 EV6 bus. Launched with 100 MHz FSB support in the earliest chipsets it evolved stepwise to faster 200 MHz FSB while maintaining pin compatibility throughout its lifetime. However, timing, BIOS and voltage differences restrict compatibility between older chipsets and processors.
Socket dimensions are 5.59 cm x 6.55 cm or 2.2" x 2.58". AMD recommends. Heavier coolers may result in damage to the die. All socket A processors have the following mechanical maximum load limits which should not be exceeded during heatsink assembly, shipping conditions, or standard use. Load above those limits may crack the processor make it unusable; those load limits are quite small compared to the load limits of Socket 478 processors. Indeed, they were so small that many users ended up with cracked processors while trying to remove or attach heatsinks to their fragile processor core; this made installing non-certified heatsink solutions a risky business.

Socket 754 is a CPU socket developed by AMD to supersede its Athlon XP platform. Socket 754 was the first socket developed by AMD to support their new consumer version of the 64 bit microprocessor family known as AMD64. Socket 754 was the original socket for AMD's Athlon 64 desktop processors. Due to the introduction of newer socket layouts, Socket 754 became the more "budget-minded" socket for use with AMD Athlon 64 or Sempron processors, it differs from Socket 939 in several areas: support for a single channel memory controller with a maximum of three unbuffered DIMMs, or four registered DIMMs no dual channel support lower HyperTransport speed lower effective data bandwidth lower motherboard manufacturing costsAlthough AMD promoted Socket 754 as a budget platform on the desktop and encouraged mid- and high-end users to use newer platforms, Socket 754 remained for some time as AMD's high-end solution for mobile applications. However, Socket S1 was released and superseded Socket 754 in the mobile CPU segment, with support for dual-core CPUs and DDR2 SDRAM.
The first processors using Socket 754 came on the market in the second half of 2003. Socket 754 was phased out in favor of Socket 939 on desktops because of low sales; the socket remained in use for laptops until it was replaced by S1 in 2006.
