Socket 939 was introduced by AMD in June 2004 to supersede the previous Socket 754 for Athlon 64 processors. Socket 939 has been succeeded by Socket AM2, although Socket 939 is still popular.
It supports dual channel DDR SDRAM memory, with 6.4 GB/s memory bandwidth. Socket 939 processors support 3DNow!, SSE2, and SSE3 (revision E or later) instruction sets. It has one HyperTransport link of 16 bit width that can run as fast as 2000 MT/s. Processors using this socket have 64KB each Level 1 instruction and data caches, and either 512KB or 1 MB Level 2 cache.
