Socket 423 is a 423-pin CPU socket used by Intel's first generation of Pentium 4 processors based on the Willamette core.

This socket was short-lived, as it became apparent that its electrical design proved inadequate for raising clock speeds beyond 2.0 GHz. Intel produced chips using this socket for less than a year, from November 2000 to August 2001.

Socket 423 was replaced by Socket 478 in 2001. Socket 478, being microPGA, was cheaper to manufacture than Socket 423.[2]
