AMD Socket 754 to Outlast Socket 939
 

Despite the need for more complex interfaces to support multi-core processors, AMD's existing socket 754 will be outlasting the more complex socket 939. Currently, socket 939 is home to AMD's Athlon 64, Athlon 64 X2 and Athlon 64 FX processors while socket 754 is for Sempron. According to AMD documentation, all socket 939 processors will stop shipping Q2 2007 with final orders occurring nearly half a year before end-date.
