    2nd generation Intel® Core™ i7-2630QM processor 2.00 GHz with Turbo Boost 2.0 up to 2.90 GHz


    and

    2nd generation Intel® Core™ i7-2620M processor 2.70 GHz with Turbo Boost 2.0 up to 3.40 GHz

    I've actually heard the Dual core was a shannanigan, based off of its benchmarks compared to the Quad core.

    What, in your opinion, does the non-word "shannanigan" mean? Your post tells the OP nothing about whether you think that is a good or bad processor.

    Assuming you're getting a system which can handle the increased heat well and you don't mind the price or possible battery life reduction then go for the quad any day (I hear you can put the i series into eco mode or something like that though which parks loads of the cores so battery life probably won't be affected as badly as you might think).

    Go to this site

    PassMark Software - CPU Benchmark Charts

    Go to Search for your CPU model and see if that has the answer you are looking for...

    Depends what you use your computer for. The more information you provide on that question, the better of an answer you'll get. For daily tasks, you won't notice any difference. For multithreaded applications, the quad core will be much faster. For single threawded applications, the dual core will be slightly faster.

    The quad core doesn't consume significantly more power in most systems (non ultraportables) than the dual core since the second generation Core i series are both on 32nm manufacturing process with integrated graphics (in the event of not discrete GPU or switchable graphics enabled) and have aggressive Speed Step. The heat should be a non factor since most laptops are designed to cool the hotter CPU or have a different heatsink vs. the dual core.

    Many laptops can't handle quads, prime example being the SXPS1645. Many i7 equiped laptops simply idle around 55-60 degrees and then when they get going they can ramp up to silly temperatures. Also, unless you do have a decent enough cooling solution, turboboost is pretty much moot.

    The 2620 dual core is be able to sustain TurboBoost almost indefinitely in the XPS 15, as long as the NVIDIA GPU isn't also at full load.

    Same goes for the 2630QM in the XPS 15. As already mentioned above the 2620M will be faster on single threaded applications. Overall the 2630QM is a much faster processor. Unless you have specific single threaded applications, the 2630QM would be the better processor to get.
