    The old 2.53 MBP had 6mb cache and I was about to buy the new 2.53 MBP when I realised Apple have halved the Cache to 3mb.

    I work in Sound Design and was wandering if the performance of the old is even better than the new model with apps like Pro Tools.

    Why have the downgraded the chips when they could have used the old ones?

    Does someone know the difference? Is the old or new 2.53 better.

    I suspect it's to conserve power and make the battery last longer.

    Just like hard drive cache, CPU cache won't make much difference. More RAM and an SSD will, on the other hand.

    Its basically super quick memory that the CPU can use to avoid having to delve into the RAM too much. The more you have, the quicker things get done. If it's the previous generation MBP (e.g. 1066 MHz FSB, DDR3 RAM, 9600M GT) then the new model will be ever so slightly slower.
