Note that they cheat in P4's favor, comparing a 3.2GHz P4 to a 3800+ A64, the latter still using significantly less power. They do note in a footnote that a P4 3.8 would use 50-70W more.

I also wonder if they have Cool'N'Quiet enabled for the idle measurement of the 3800+?

And, of course, Winchester has much better power char. Too bad they didn't throw in a 3500+ Winchester.

Also, the "high P4" (actually mid-range) has only 1/2 the memory of the A64 system. 512MB vs. 1024MB.
