These articles list the new Socket AM3 Phenom IIs and their likely US prices. These will work in current Socket AM2 motherboards with DDR2 memory, or new Socket AM3 motherboards with DDR3 memory. The use of DDR3 will improve performanec by up to 5% depending on workload, and there is another boost from the 200MHz increase in northbridge and HT speeds on all AM3 models. All of these listed are expected to arrive within the next 2 weeks, while the 945 and 950 are in Q2.
Confirmed:
Phenom II X3 710 (Tri-core, 2.6GHz, 6MB L3, 95W TDP) (~$124)
Phenom II X3 720 Black Edition (Tri-core, 2.8GHz, 6MB L3, 95W TDP) (~$144) *Unlocked multiplier for easy overclocking*
Phenom II X4 810 (Quad-core, 2.6GHz, 4MB L3, 95W TDP) (~$176)
Rumoured (unsourced, but seen on AMD roadmaps):
Phenom II X4 925 (Quad-core, 2.8GHz, 6MB L3, 95W TDP) (probably $195 - same as current 920)
Phenom II X4 945 (Quad-core, 3.0GHz, 6MB L3, 125W TDP) (probably $235 - same as current 940)
Phenom II X4 950 (Quad-core, 3.1GHz, 6MB L3, 125W TDP) (>$235)
