Quote: "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."

Quote: "In this article, Benchmark Reviews tests the newly re-vamped AMD Phenom II X4 965 BE desktop processor. For all intent and purpose, the AMD Phenom II X4 965 Black Edition processor has not changed. The model number is now HDZ965FBK4DGM, and the total TDP is down from 140W to 125W. The X4 965 CPU still honors the AM3 socket, and uses a 45nm process to construct the 258mm2 die. GlobalFoundries FAB1 has added C1E implementation on the hardware level, and DDR3 is now supported at 1333MHz for 'Heavy' loads. Ultimately though, the 3.4GHz is still the same overclocking beast it always has been, and performance is relatively unchanged."

The company is AMD (Advanced Micro Devices) and I will be looking at one of their new X4 Athlon II CPU’s the X4 620 2600Mhz."
