    Hi Guys! I ordered the 2.6ghz 15" on the night of the release - and I kinda have a question.

    With the newly released GeekBench results, I kinda found it a bit strange, that the score is about 2 times of what the haswell 13" i5 dual core gets?

    Shouldn't this be much higher?
    The air has 2 cores clocked at 1.3 ghz scoring around 6.5k
    The pro has 4 cores clocked at 2.6ghz and scores +-12k

    Can anyone explain the logic to me?

    It's roughly double because there's double the cores. You're forgetting that during benchmarks the CPU's are running at basically top 'turbo' speed not the base clock.

    The Air (in question) turboboosts to 2.6 ghz (2 cores)
    The Pro (in question) turboboosts to 3.8ghz (4 cores)

    It's still a puzzle to me. Way higher Cache among other things.

    I think you're paying too much notice to the clock speed, it doesn't work like a maths equation where the dual core is 2x1.3 and the quad core is 4x2.6

    It looks like the the i7 chip on the MBA and the MBP 13" score pretty much the same performance-wise. And the i7 is about 10% faster than the i5

    Geekbench is also a pretty useless benchmark. You need to measure both machines running the applications and tasks that you actually use to judge how much faster one is than the other.
