AMD has revised its current flagship CPU, the Phenom II X4 965 Black Edition into a slimmer electricity sipping 125W model, down from the initial 140W TDP processor released earlier this year. Since this is a refresh, there are only a few differences between the otherwise identical CPUs. New to the "C3" 125W revision AMD Phenom II X4 965 Black Edition is hardware implementation of the C1E enhanced halt state; basically a tool in the CPU power saving chest to reduce clock speeds on the fly.
