Should be:
X5482 12MB 3.20 GHz 1600 MHz DP 150W
E5472 12MB 3.00 GHz 1600 MHz DP 80W
E5462 12MB 2.80 GHz 1600 MHz DP 80W
I am guessing due to cost, power and cooling they will not use the X5472, but I could be wrong and it might be shipping instead of the E5472.
Once they get into reviewer's hands, we will know for sure.
Amazing. I called the apple store and all the guy could tell me was "harpertown" processor. What retards. Why does Apple make it so hard to find this out? Professionals care about details and why do they want us to hunt for it?
