Socket 5 was created for the second generation of Intel P5 Pentium processors operating at speeds from 75 to 133 MHz[1][2] as well as certain Pentium OverDrive and Pentium MMX processors with core voltage 3.3 V. It superseded the earlier Socket 4.

It was released in March 1994.

[3] Consisting of 320 pins, this was the first socket to use a staggered pin grid array, or SPGA, which allowed the chip's pins to be spaced closer together than earlier sockets.

Socket 5 was replaced by Socket 7 in 1995.
