Is hyperthreading a mistake ?
Well, all we know now that hyper trading is. :(
But , can we be clever enough to know that hyperthreading is a mistake too?
Yeah, this finding might be a hint. On the other side, large power consumption at Core i7 has no so obvious cause. It is not clear from the picture above howPhenom II is tested in a comparative way in a hyperthreading mode when it doesn't support hyperthreading?
The best thing here is that Phenom is better even in situation when Cool n' Quiet failed.
The main cause of Intel's huge power consumption measured is in a fact that its architecture still isn't power optimized , and after EIST being switched off, its overall power consumption simply exploded. Phenom C2 revision (Phenom II) took clever architecture trade (lower HT clock) to minimize power consumption. Intel's Hyperthreading mode simply hogs its i7 core's connections. Intel's i7 is thus in power consumption sense simply a statistical mix of two consumption extremes: EIST and hyperthreading modes.
