    everyone intel-minded says don't look at the TDP, your quadcores don't consume that much, but when AMD releases a quadcore with 125W, suddenly it is bad....
    Intel's TDP and AMD's TDP are two different things in general. Both technically are the maximum power usage, but AMD's CPUs tend to actually consume close to TDP under maximum load. Intel, on the other hand, bundles up together CPUs into "classes" and gives them all the same TDP, regardless of actual power consumption. For example, Intel rates all 45nm duals at 65W despite them consuming 30-40W at most, meanwhile AMD rates certain duals at 45W that consume more than chips that Intel rates at 65W. Same thing with quads....... Intel's 130W QX9650 consumes less than AMD's 95W launch Phenoms. In general, AMD's TDP is much more aggressive than Intel's TDP.

    i7 TDP is 130W that's my answer
    See above, and performance/W comes into factor there..... only time i7 gets close to consuming that much power is when all 8 threads are under use, and in an app that takes advantage of HT performance is going to be significantly higher for the Core i7 CPU.
