Well it's the dual-core K8 clocking more than dual-core P4 that I am sure of at <= 115W TDP and we won't see any dual-core 3GHz Prescotts under the same TDP conditions without some sort of extreme cooling which of course will breach the nominal TDP. You only have to add the TDPs of 2 * 3 Ghz Prescott Celerons and you get 146W. AMD already have 2 Ghz parts at 35W. Semiconductor and thermal physics may defeat you here and dual-Prescott at 90nm may come to exist as a product but it won't be competitive.
