OK, enough!!!! I've been listening (reading) too much BS and speculation in the course of this thread... I've listened to how the only difference is the 1MB extra of L3 cache and the 130MHz clock speed. This is right. I've heard so much preposterous nonsense that I am gonna break it down for you babies:

As you can see, appart from the Processor Number, the Clock Speed and the L3 Level Cache Size, other differences are Max Turbo Frequency, Bus/Core Ratio and intriguingly the fact that the i7 version is Embedded.
Oh, and I forgot the difference in the Budgetary Price
