Not really as Prescott had a similar laundry list of ipc improvements which in some cases did deliver ~10% improvement over Northwood. However in many other cases there was a ~10% drop due to higher first and last level cache latency, just like Nehalem, and generally Northwood was thought to have the better ipc especially in the crucial desktop market of games. So there is a historical precedent here both for bold vendor predictions and a radically different reality when the processor arrived. Nehalem designers will really have done well if there are no backward steps somewhere in the performance profile but they are fighting mpu history here along with the performance primary order of magnitude importance that is cache latency. I'm just tempering all your 'uber alles' Nehalem propaganda here with caution based on the recent history of both Prescott and Brisbane. "Those who forget the lessons of history are doomed to repeat them" ;-)
