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.
