Less per MHz doesn't matter much if the frequency is much higher, or it does? I mean, if you put, say, a 133 MHz pentium and a 1 GB pentium to do the same thing with the same SW (mail server, for example), the 1GB system may use less per MHz (newer silicon, lower voltage, etc...) and its flip-flops toggle for a smaller percentage of time, but its electricity bill will still be the higher one, or not? In general: has anybody ever done *this* kind of benchmarks? Comparing electricity consumption among different systems doing just the same task?
