Yeah, but those lines don't look good - powersaving needs more energy than performance. And what is even crazier is that fixed 1.2 GHz case. I'd guess in the normal case those cores are at triple the freq. - i.e. somewhere around 3-4 GHz. And yet, 1.2 GHz eats almost *double* the power than performance and powersaving. So for the x=8 and maybe even the x=16 case we're basically better off with performance. Or could it be that the power measurements are not really that accurate and those numbers above are not really correct? Hmm. -- Regards/Gruss, Boris. Sent from a fat crate under my desk.
