FX-55 (2.6Ghz) 1M May 04 A64 3800+ (2.4Ghz) 512K May 04 A64 3500+ (2.2Ghz) 512K May 04 A64 3700+ (2.4Ghz) 1M Apr 04 (socket 754)
The 3800+ (2.4Ghz) A64 is also due in May. The additional 512K cache that the FX line has is not enough to justify a premium brand and price. That have to keep it ahead in frequency to maintain its image. So they either have to delay 2.4Ghz A64 parts, or ship a 2.6Ghz FX.
Speed binning must be pretty good. AMD is looking like it will have a very strong year.
FX-55 on 939 is simply going to slaughter the competition on benchmarks.
