Socket 8 CPU socket was used exclusively with the Intel Pentium Pro and Pentium II OverDrive computer processors. Intel discontinued socket 8 in favor of Slot 1 with the introduction of the Pentium II.

Socket 8 has a unique rectangular shape with 387 pins, a bus speed ranging from 66-75Mhz, voltage from 2.1 - 3.5V, and support for Pentium Pro chips from 150-200Mhz, Pentium Pro OverDrive CPUs, and Pentium II OverDrive CPUs. This unique shape is the only currently known arrangement of two geometries for pins. On one half of the socket, it was in the common rectangular grid, and on the other half had an offset arrangement like the socket 7.
