Following our original story, we finally have the real answer about Nehalem generation, Bloomfield CPU Thermal design power. We were right all along, 2.66GHz Core i7, 2.93GHz Core i7 and 3.2GHz Core i7 will all have 130W TDP.

At this time, Intel doesn’t want to discuss the clock speeds, but sources close to the company have indicated that a slower clock part, let’s say 2.66GHz Core i7, will have a lot more space for Turbo feature at 130W TDP than any other.

This is Intel playing it safe, as the actual TDP of the 2.66GHz part will be lower than 130W, but in case of automatic overclocking called Turbo, you might get close to 130W. Turbo will overclock your Nehalem CPU if your thermals are right and if there is a space for Turbo.

This means that all Nehalems will fit to 130W and within this frequency the 3.2GHz part won’t have much space for turbo clock increasing features, while 2.66GHz part will probably be able to use its turbo mode at a much higher rate, giving you much more performance.
