6 cores

[assmunk]

this is true but if you remember correctly Advance Micro Devices (Amd) is the most energy efficient, after all 45w dual cores and 65w quad cores.

Edit

core i7 should be meant for the server industry not desktop, and im looking at that cpu and comparing it to a core2quad, one of the 45nm http://www.newegg.com/Product/Product.aspx?Item=N82E16819115041 it has more cache 12mb compared to the icore with 8mb of l3 and like 2mb of l2. if you think about it the only real difference is power, hyper threading and L3 cache, thats just about it.
