AMD’s Web site seems to confirm that the recently launched Athlon 64 FX-62 (2.8 GHz, 1 MB of L2 per core) and Athlon 64 X2 5000+ (2.6 GHz, 512 KB) will be available in socket 939 versions. The company’s “Processor Pricing” page lists the parts as “socket AM2 and 939”. If the information is correct, it means that users willing to upgrade to the top of the line chips will not need to change motherboards and memory (to DDR2), besides the CPU. The FX-62 costs USD 1,031, while the X2 5000+ sells for USD 696, both in 1,000-unit quantities.
