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 is the second socket designed for AMD's AMD64 Range of processors.
[edit] Availability
It was made available in June 2004 and replaced by AM2 in May 2006, although production continues through at least the beginning of 2007. AMD's official position is "we plan to support the socket 939-pin package parts as long as customer demand warrants it." Demand for and sales of Socket 939 are still strong as of Q1 2007.
[edit] Technology
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.
