quote: Extended halt power for core 2 duo is 22/12W (available in Intel's datasheet.) Believe the 12W figure is for the 2MB. Either way, yes, gate leakage can be more of an issue when not in standby, depends upon the design.
Anyway, all those figures are based upon the current conroe at 3GHz. And even if you increase the figure by the amount of core logic increase going into wolfdale, you still only get 50W. Either way, at this point it's all just speculation anyway. Intel's current figures are just based on simulations since silicon isn't at speed. So even if that was an actual roadmap, Intel wouldn't have lowered TDP on it in the least.

That said, what does the interface between dielectric and silicon have to do with electron mobility through the channel area? Part of the desirability of halfnium in my understanding was that it interfaced so nicely with silicon, the problem was always on the gate electrode.
