Wanna_bmw, Re: The value you have listed for the 1GHz Pentium III is what the processor dissipates under the unlikely scenario that every transistor switches simultaneously.

Yes, thanks for pointing that out. I believe that's what Intel is calling TDPmax in their data sheets (or in other words: the maximum power consumption possible) and it's of course not equal to TDP. However, I am not sure what AMD is specifying in their data sheets. If it's the "normal" TDP, those numbers can't be compared to Intel's. But unfortunately they are the only one in the sheets. Judging from the Athlon power consumption an Athlon 4 at 1 GHz should consume a maximum of around 31W (lower voltage + 20% power reduction because of the core redesign).

Re <<...processor dissipates under the unlikely scenario that every transistor switches simultaneously. >>

That is not possible, just by how a processor works. At any given time a small fraction of transistors are switching.

That number (34.0W) is experimental. They run software like CAD, photoshop or multimedia and measure the output from the CPU.
