How is Intel going to get the 1GHz PIII to run cool/efficient for notebooks?

I know there will be a new PIII 0.18u stepping soon, but we all know that at 0.18u the PIII design is pushing the limits at 1000MHz. Even the 1GHz for desktop systems runs a 1.75v (maybe 1.70volts, not sure) and requires serious cooling.

How are they going to get this thing running at a reasonable voltage for notebooks? I guess if they can reduce the voltage the cooling will kind of take care of itself. Even with speed step backing down to 900MHz when on battery power, getting this chip to run at under the 1.6 volts required for efficient notebook operation is going to be a feat with the PIII and 0.18u process technology.

I think you mean .13u stepping
and cooling maybe the reason that they haven't released one yet.
They usually have a mobile version of every chip thats smaller and has less heat dissapation through different techniques.
I foresee them not finding a way to do it for a while. And they're not too worried...AMD hasn't really put its foot into the mobile market yet so Intel is sitting on its heels till then.

What a joke! Have you checked how hot the AMD chips run? A lot hotter than P3's, and usually higher voltages as well.

As for how they will do notebook CPUs, it will be as Intel has always done - the newest technology goes in to notebook CPUs first, ie. the first 0.13 CPU's will be notebook CPU's. Just as the P400 notebook was the first 0.18 CPU ...
