It appears the 2.2 i7 in early 11' MBP are faster than the 2.2 i7 in late 11' MBP

    Some links comparing the processors.

    For some reason the 2720QM 2.2 i7 performance gain is 8% over the similarly clocked 2675QM 2.2 i7

    http://processors.findthebest.com/compare/90-92/Intel-i7-2720QM-vs-Intel-i7-2675QM

    http://compare-processors.com/rank/all.php?Core+i7-2720QM=on&Core+i7-2675QM=on&cp=Compare

    The 2720Qm is actually closer in performance to the higher clocked 2760QM. The difference between it and the 2760QM 2.4 i7 is only a 3%

    Evidently all 2.2 i7 CPUs are not the same

    Of course the Early 2011 2.2GHz is faster than the Late 2011 2.2GHz processor.

    The Late 2011 processor is an evolution of the original Early 2011 2.0GHz processor. It has lower turbo modes and overall it is a lower end chip. Just look the the processor numbers: the Early 2011 chip is 27xx whereas the Late 2011 is 26xx—not the same family.

    The Early 2011 2.2GHz chip is succeeded by the Late 2011 2.4GHz chip in terms of features, functionality, and performance.

    Yeah I wasn't aware of the differences 27 vs 26. I just would figure that a SB i7 2.2 is the same as any other SB i7 2.2. Are the 2720 and 2760 the same chip with just a higher multiplier for the 2760?

    Maybe this was common knowledge but I think it's good to know. Especially if you are buying a new or used MBP.

    Yes, the 2760 is the same thing as the 2720 with a higher multiplier.

    Thats a bit odd to know.
    I mean the price on these 2 processors are same.
    Yet they are bit slower.
