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.

It was made available in June 2004 and replaced by AM2 in May 2006. AMD has reduced the production of this socket to focus on current and future platforms, although demand is currently very high. This is to say that when the AMD2 chips came out, many people were still using 939 PIN sockets, therefore increasing demand. Recently, only Athlon 64 X2 4200+ model (90 nm process, 2x512 KB L2 cache, 89W, E4 and E6 steppings) model on this socket was available in the lineup of processors [1].
Both single and dual-core processors were manufactured for this socket under the Athlon 64, Athlon 64 FX, Athlon 64 X2, Sempron and Opteron names. The Opteron 185 and Athlon 64 FX-60, both featuring a 2.6 GHz clock speed and 1 MB of Level 2 cache per core, were the fastest processors manufactured for this socket.
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.
