"It appears reading through all of this, that I have drawn the conclusion that Intel rates their chip to operate at a different die/junction temperature (~80C for INTC versus 95C for AMD) ... Is this correct, Mani?? If true, this would indicate a different level of required chip reliability between the two companies." Not necessarily. That could be one reason, another reason could be that they are pushing their process more. Intel regularly lowered the max. operating temp. of the PIII's when it was trying to reach, ad exceed 1GHz. Or it could be that electro-migration is worse under higher temperatures with Intel's 0.18 micron Al process than AMD's 0.18 Cu process, and to get equivalent (or even not quite as good) chip reliability Intel has to have a lower temp. spec. It would be more accurate if you had posted "If true, this could indicate a different level of required chip reliability between the two companies." because there are several possibilities...
