    So I was looking at the new iMacs, and was wondering if/how much faster they are compared to an MBP?

    If we compare two fairly high-range models from both lines.

    15" 2.2GHz Quad-core Intel Core i7 MacBook Pro (Standard RAM, HD etc)
    27"/21.5" 2.7GHz Quad-core Intel Core i5 iMac (Standard RAM, HD etc)

    ^I'm guessing the 2.2GHz 27 and 21.5" are practically the same, as all the specs are the same except the screen size?

    So, would a higher clocked i5 be faster than a lower clocked i7? (Bearing in mind one is a desktop chip and the other is a mobile chip)

    Geekbench seems to indicate there's very little difference. Is this the case in real-life? Thanks.

    i7 supports Hyper-Threading whereas the i5 does not. That is the main difference between the chips. In real world, most apps do not benefit from HT so i5 should be a bit faster in real world, although that will depend on the app.
