    I can get the Intel Core 2 Duo Processor P8600 (2.40GHz 1066MHz 3MBL2) 25W or the Intel® Core™ 2 Duo processor P8700 (2.53GHz 1066MHz 3MBL2) for the same price. I am ordering Windows Vista Home Premium and then planning to upgrade to Windows 7 later. Which one is the better option?

    If they are the same price then go for the P8700.

    If you are getting them for same price order the P8700 which is slightly faster than the P8600.

    Likely, Lenovo messed up again. I got my P8700 when Lenovo accidentally priced it the same as the P8600. There is no downside of the P8700 over the P8600 - they use the exact same amount of power, and put out the same amount of heat, the P8700 just runs a tad bit faster.

    So, in short, for the regular $50 upgrade price, not worth it; for free, definitely go for it.

    Indeed as MidnightSun said, there is no difference between them at all except the highest unlocked multiplier on the P8700 is 9.5 whereas on the P8600 it is 9. This means things will be a little tiny bit faster on the P8700.

    They're both 25W processors so speed is the only real difference. I ended up getting the P8800 for the same price as the P8700 just by experimenting with various configurations. Go figure.

    from cpubenchmark.net:
    processor / performance score / rank
    Intel Core2 Duo P8600 @ 2.40GHz 1590 154
    Intel Core2 Duo P8700 @ 2.53GHz 1791 126
    Intel Core2 Duo P8800 @ 2.66GHz 1509 163

    LOL. you got the P8800 which has a higher clock but is inferior in performance score and rank to even the P8600...

    For everyoen else - if you're paying $20ish/$30ish for the upgrade to the P8700, take it - it's a significant jump (12.6% in performance testing even though it's only a 5% increase in clock speed) over the P8600. and whatever you do, DON'T get the P8800!

    The P8700 according to benchmarks performs at par with the P9500 which is a handsomely priced processor.

    Obviously the one doing the benchmark screwed up and the CPU was throttling.

    In simple terms, 2.66 > 2.53 > 2.4 GHz (for the same CPU core/architecture).

    sure, other things factor in such as RAM, motherboards etc.
    But at the end of the day the results are based on hundreds if not thousands of results from tests run on those CPUs.

    but if you're assuming there's a skew, you're claiming that the 500 users (e.g.) who tested on the P8800 had lower performing machines in other ways aside from the CPU than the 500 users who tested on the P8700. That'd be quite a disparity no?

    P8600: 485 samples
    P8700: 119 samples
    P8800: 4 samples

    You happy?

    LOL touche ;)
    looking forward to seeing P8800 go up that list (if at all). Those poor 4 users must have one hell of a lot of bloatware running on their pcs :)

    Statistically speaking, 4 samples in comparison to 485 or 119 samples is not significant enough to base a decision on.
