Anyway, "Shanghai" Opterons are expected to push performance forward while improving a bit on the power consumption. I feel the performance alone is the primary focus here: combining an expected 15 per cent - 20 per cent better per clock throughput compared to Barcelona with up to 3 GHz initial clocks (3.2 GHz early next year) will not beat Nehalem Gainstown DP, but will come sufficiently close to keep the competition going. Also, unlike Nehalem, "Shanghai" will be available in the 4 to 8 socket MP version right away, which could keep them superior performance-wise prior to the Intel Dunningtons for a while, until the Beckton Nehalem generation is out in a year's time. Talking about those AMD MP boxes, an early HT3 speed support introduction would definitely help scale better across more sockets.
