Doesn't the Prescott run hotter than the Northwood at the same clock speed (3.2 GHz)?. But the performance increase (if any) is neglible. Some benchmarks seems to say that the Northwood actually runs faster in some cases. Am I missing something?
Prescott is hotter and runs slightly faster than the Northwood. However, a Prescott has better ocing capabilities. You can usually get about a 1 GHz oc with minimal voltage icnreas on a Prescott, where as on a Northwood it is arduous to get a 400 MHz increase.
