What's faster: a MBP with a 3.06 GHz Intel Core 2 Duo or 2.3GHz Quad-core Intel i7?

    I have a MBP that is showing age. I'm thinking of a buying a new (well, refurbished) one.

    I was looking online to compare speeds but I couldn't find the answer. So, simply put, I'm looking at a 2012 or 2013 refurbished MBP that has a 2.3GHz Quad-core Intel i7. My current 2009 machine has a 3.06 GHZ Intel Core 2 Duo.

    Which of these is faster?

    The 2.3GHz Quad-core Intel i7 is faster by miles.

    In some cases the quad core Intel Core i7 will be many times faster than your Core 2 Duo due to the new instruction sets and more threads. Also keep in mind that the i7 completes more instructions per cycle.

    I always use geekbench for that kind of questions:
    http://browser.primatelabs.com/mac-benchmarks

    What I like in particular is that it has scores for single and multi-core. Now your old machine has:
    1629 (single, 32 bit)
    2863 (multi-core, 32 bit)

    The 2.3 GHz rMBP reaches
    3106
    11807

    so about twice as fast in single core and up to 4x as fast in multi-core tasks. It's not even close ;)

    Here is the Geekbench results, the i7 2.3 is faster by a mile.

    The 2.3GHz i7. It's faster by several orders of magnitude.

    http://browser.primatelabs.com/geekbench3/compare/412593?baseline=557191

    3.06GHz C2D T9900 vs 2.3GHz i7-4850HQ:
    Single core: 1818 vs 3578
    Multicore: 3280 vs 13825

    Quad core any day my friend. It's got like 8 threads in it (2 per core) so basically you can do many tasks with no lag. Pretty sweet stuff! :D
