well, in the HPC world, correctness is normally paramount,

They overclock themselves...


Turbo Boost, inspired by the famous car in Knightrider from Michael Knight i bet :)

Provable for spec tests they overclock a tad more (200-400Mhz) than when you test one at home... ...at home it just manages to overclock 1 core, not all 8 logical cores, unlike at spec where of course it gets cooled well enough to overclock at 8 logical cores the same amount like at 1 core. Or maybe it wasn't
better cooling for the spec test, but simply a better chip?

Without turboboost i7 performs the same for my software like core2.
