>> Phenom II X4 810 and X3 720 Review
AMD is unveiling their AM3 platform today with the launch of the Phenom II X4 810 and the Phenom II X3 720. These sub $200 processors are paving the way for DDR-3 support with AMD processors. While their support for DDR-3 is nice, they still are compatible with AM2+ sockets and DDR-2 support. These two processors help to flesh out AMD's offerings for the budget marketplace, and should allow AMD to transition that much faster to all 45 nm parts.
