Socket 939 processors were specifically designed for CPU’s and it was produced by the computer company AMD in June 2004. The 939 processors were created as a replacement for Socket 754 which was used in Athlon 64 processors at that time. When AMD decided to develop the AMD64 processors, the 939 processors was also replaced by the Socket AM2 in May 2006.
Socket 939 processors and mother boards were introduced to the market on June 2004. In May 2006, the full focus of AMD’s manufacturing was turned to the production of Socket AM2 which led to the production hold of the 939 processors. However, even when the 939 processors production was stopped, a 939 processor motherboard was assembled with the use of the latest chipset intended for Socket AM2 processors. These 939 processors were further developed and were released in the year 2009.
Socket 939 processors make use of the dual core as well as single core processors for the Athlon 64, Athlon 64X2, Opteron, Athlon 64X, and Sempron. The quickest socket that was produced for the 939 processor were the Athlon 64FX-60 and the Opteron 185. These two sockets have 2.6 GHz clock speed and 1MB level 2 caches per core. However, the fastest socket that was designed for the FX-57 which ran at 2.8 GHz.
