AMD's Socket 939, Athlon 64 FX-54 amd 64 3800+

BudKnight writes "It looks like AMD is launching four new desktop processors, a new core, and a new socket infrastructure today. HotHardware has tested AMD's two new flagship processors, the Athlon 64 FX-53 and the Athlon 64 3800+. The new FX-53 no longer needs registered memory to function and the 3800+ has only 512K of cache, but it gets an upgraded 128-bit memory controller. The usual suspects also have reviews posted as well - TechReport, Hard|OCP, Beyond3D - more are sure to follow."
