[edit] Availability

It was made available in June 2004 and replaced by Socket AM2 in May 2006. AMD has reduced the production of this socket to focus on current and future platforms.

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 dual-core processors manufactured for this socket. The FX-57 ran slightly faster at 2.8GHz, making it the fastest single core processor supporting the socket 939 interface.^[1]

[edit] Technical Specifications

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 256KB, 512KB or 1 MB Level 2 cache.^[2]
