I'm not sure of that, because it's not easy to find data sheets saying something about idle load and other loads and how much of the energy will be transformed into thermal energy, but it might be near to a calculation like this: > 95W / 2 dual-cores = 47,5W/dual-core > > 2 cores need 45W for the Athlon X2, resp. 47,5W for the Phenom.
