    if i have MBA with i5 1.7 GHz and MBA with i5 1.8 GHz, is there any difference?
    can someone explain what that GHz does, i think what bigger it is, that better it is. Am i right? What does that GHz do, is it important?
    what about if i have i5 1.8 GHz and i5 2.5 GHz, is there a difference
    or 2.0 and 2.7 GHz?

    i5 and i7 is there some kind of big difference?
    help me ! :eek:

    if you are talking about the difference between the i5 in the 11 and 13 inch macbook, it looks like their might be a rather sizable difference. To me it looks like they both have the same bus speed and cache size but I find it hard to believe that the small clock speed difference would account for it.
