    They shouldn't run any hotter than the Unibody Macbook Pro's. Both Core 2 Duo and the new i5/i7 are 35 watt ships, and the i5/i7 are more power efficient.

    How much do the Core 2 Duos that are now being used consume compared to the new i5 and i7 processors?

    In terms of speed, they are like this:

    Passmark CPU Benchmark:

    Current:

    i7 620m @ 2.67GHz: 2735

    i5 540M @ 2.53GHz: 2444

    i5 520M @ 2.40GHz: 2346

    Last gen:

    C2D T9900 @ 3.06GHz: 2292

    C2D T9600 @ 2.80GHz: 2009

    C2D P8800 @ 2.66GHz: 1874

    C2D P8700 @ 2.53GHz: 1798

    C2D P7550 @ 2.26GHz: 1618

    C2D P7570 @ 2.26GHz: 1592

    Even the fastest last gen is slower than the slowest current gen. Like I said before, the i series is more power efficient thus longer battery life.
