i dont think amd or intel designed their process'es to run well on either low or high temps... and amd chips can run high temps, they just dont clock as well when running hot.

thats actually a hint towards the properties of the process and the cpu design... if a chip doesnt clock well when it runs hot on air, the chip is limited by heat and will most likely clock well under cold.

intels chips clock well on air, even at very high temps, so heat is not really limiting them or holding them back a lot, which also explains why they dont gain much when going subzero...

i think in the end this has a lot to do with processor design as well and not just manufacturing process... but anyhow, what does this have to do with this new phenom extreme edition chip? who cares how they build it as long as it clocks well
