simple question, which chip is better in terms of PPD and power consumption? the price of the new 6core AMD chips looks really competitive and i'm considering buying one. i'm not looking for gaming, subzero, or rendering performance, it's solely to crunch with.

it's my understanding that an intel's HT makes each core ~50% more efficient, so a quad with HT is about equal to a a true 6 core chip with no HT. i'm assuming that the i7 will generally OC better and consumes lower power at the higher clocks, but i could be wrong. which chip has the upper hand in computational power and power consumption between 3.6ghz - 4ghz? and please, i do not want to turn this into a battle between fanboys that swear by either chip.
