    When you buy a new MacBook Pro you get to choose between 2.2GHz Quad-core Intel Core i7 (which more precisely according to wikipedia is 2.2 GHz quad-core (2720QM) Intel Core i7 Sandy Bridge with 6 MB on-chip L3 cache) and 2.3GHz Quad-core Intel Core i7 (2.3 GHz (2820QM) with 8 MB on-chip L3 cache) for $250 more.

    Now I found this benchmarking site: PassMark - CPU Benchmarks - List of Benchmarked CPUs

    and according to them 2720QM scores 7155 in Passmark CPU Mark (rank #17) while 2820QM scores 4882 (rank #66).

    So my question is - how is that possible that I pay $250 more for significantly worse performing cpu?

    What's up with that? Any thoughts on that? Some other benchmarks..?

    Those benchmarks mean nothing, its all user submitted stuff so if someone was running a lot of other things when the assessment was running or if it was down clocked or something it would adversely affect the scores.

    Don't put any weight into new passmark scores.

    CPUs are not worth the upgrade cost for 99% of users and if you're in that 1%, you know you are.

    I thought PassMark was more reliable, thanks.
