    I currently have a mid-2010 15" Macbook Pro with an i5 2.53GHZ. I'm considering upgrading to a 2012 13" Macbook Air with i5, maybe i7, I haven't decided. Anyways, for the i5, it says Turbo Boost up to 2.8GHZ. So would that mean the 2012 MBA CPU would be faster than my current 2010 MBP CPU?

    According to Geekbench, the 13" top of the line 2012 MBA would be twice as fast as my current 2010 MBP w/ 8GB of ram and an SSD. I feel like that's not super accurate, hence why. Maybe it is though? Would the MBA be twice as fast as mine?

    Still doesn't quite answer my question though. Thanks anyways!

    Your current MBP has an i5 2.53GHZ. Turbo Boost will ramp up internal clock speed (per Wikipedia article). You asked:
    I think the answer should be easily calculable using arithmetic and the Turbo Boost ramp-up explanation in the Wikipedia article.

    You did ask about CPU (you wrote it twice in your question), so forgive me if I thought your question is about the CPU, rather than overall performance of the system as a whole. For overall performance, looking at overall benchmarks is probably a better performance measure; Turbo Boost is only one factor.

    Ah, you're right, sorry about that. Thanks!
