Socket 7 is a physical and electrical specification for an x86-style CPU socket on a personal computer motherboard. The socket supersedes the earlier Socket 5, and accepts Pentium microprocessors manufactured by Intel, as well as compatibles made by Cyrix, AMD and others.

Socket 7 was the only socket that accepted such a wide range of CPUs, (range of speeds and CPUs from different manufacturers).

Differences between Socket 5 and Socket 7 are that Socket 7 has an extra pin and is designed to provide dual split rail voltage, as opposed to Socket 5's single voltage. (However, not all motherboard manufacturers supported the dual voltage on their boards initially.) Socket 7 is backwards compatible; a Socket 5 CPU can be placed in a Socket 7 motherboard.

Socket 7 uses a SPGA socket, either a 296 pin LIF arranged at 37x37 (which is very rare), or the much more common 321 pin ZIF arranged at 19x19. Staggered Pin Grid Array or SPGA is a style of socket used on some integrated circuits, usually CPUs. ...
