Why are the performances of the 15" and 17" MBP's different?

    Might be something disastrously obvious, but take the stock hi-end 15" and the stock 17" (both with the 2.2ghz quad i7), why does the 17" score higher geekbench and other benchmark scores?

    Are you comparing the overall result or specifically the processor?

    If it's the overall I guess you'd have to find the component that benchmarks higher on the 17. Maybe they don't throttle the video as much because there's more physical space to manage heat output with?

    Overall result. Very logical answer that, could well be the reason. Thanks!

    I agree with more physical spacing, layout and cooling will play a part in overall performance.

    They have the same stock video card? Been a while since I checked them out.

    17in h macbook has a bigger screen which would require a bit more graphic processing. in addition its larger so the compnants can run more efficiently with better cooling due to larger space.

    its ment to be a desktop replacement rather than a portable laptop so it seems right that it would perform a little better than the 15inch

    cheers

    I think that the cooling system is better in the 17" (more aluminium so better heat dissipation). Thus, the CPU can run in Turbo boost mode for a longer time.
