Either this is a typo in Intel's official documents that we've seen, or it means that 3.2GHz, which is 600MHz faster than 2.6GHz Nehalem, will have the same TDP.

We've seen the same numbers before, which might indicate that these are the real numbers. The first chips to bear the Core i7 name will be mainstream desktop parts meant for gamers and conventional systems; Intel doesn't allude to the expected 3.2GHz speed but has previously confirmed the new architecture's switch from a front side system bus to point-to-point connections between the processor and peripherals, an on-die memory controller, and Hyperthreading that can at times double the number of effective cores working on a given task at any one time.
