    Thought this was a great article...

    Just going to point out that while Phenom II increases performance, Phenom II decreased Uncore clocks from 2GHz to 1.8GHz. So AMD will be gaining that performance back with AM3 DDR3 processors launching soon, which will use a 2GHz Uncore.

    I'm looking quite forward to my PhII sample to compare the performance scaling.

    There's more to tell about the techy aspects of the P2 than one would think. Lostcircuits has some good insights: d=1
