    Looking at apples site building a new macbook air with the new haswell i7 and I wanted to know the exact model number of the processor to look up its benchmarks, of course they don't have those details listed. Does anyone know the exact model number of the new haswell mobile processors that apple is using in their macbook airs?:confused:

    This is what Apple says:

    i5 1.3Ghz (2.6 Turbo Boost)
    i7 1.7Ghz (3.3 Turbo Boost)

    Based off this:

    They are respectively these processors:

    Here you can see how they compare:

    Since the battery life on the new Air is great (overkill maybe?), i would have rather had a i7-4558U in it (2.6Ghz base clock and Iris 5100). With it we would get the same battery life as the current Air, but also a much faster processor and intergrated graphics card.
    Such a shame, and the screen of the Air is a joke. All companies are going to offer high resolution screens...

    The i7 you mentioned is a 28W TDP, nowhere near the 2012 Air's 17W. It'd get pretty bad battery life and get a lot hotter too.

    This! I'd rather have a slower processor rather than one that constantly shuts down due to over heating! :) Apple actually used the fastest 17w i7 processor.
