    just an fyi your math is a bit off on the oc comparisons, the wprime results are actually more significant than the super pi results.

    also the super pi gains are just under 20%, not 25%.

    http://www.csgnetwork.com/percentchangecalc.html

    always rememeber it's original number minus new number over the original number.

    in the case of super pi it's (1322.49-1061.94)/(1322.49) which = a 19.697% decrease in value or in this case a near 20% performance improvement

    then the wprime oc change would be (440.21-342.44)/(440.21) which = a 22.21% decrease in value or in this case a 22% performance improvment

    this of course makes the latter part of the following statement

    as well as the first part of this statement

    incorrect.



    total nit-pick in an otherwise great review, but there it is.

    Actually, overclocked system takes 19,7% less time to complete the task, but based on those numbers, it is 24,5% faster. That means a cca 25% boost, so that part is correct in the article.

    With wPrime, there sure is some mischief in the article.

    original value must come first, it's only 25% if you compare the amount changed to the overclocked number. That is an incorrect way of doing percentages.

    [​IMG]

    1322.49 is the old value or the original value

    1061.94 is the new value

    yogurt_21> You fail to understand, that saying:
    a) solution A is X% faster
    and
    b) solution A needs Y% less time
    are two different things.

    For example, if stock system takes 100 seconds and overclocked system takes 50 seconds, it is correct to say: overclocking provides 100% boost, because the overclocked system is clearly twice as fast as the stock system. But your "correct math" says that the difference is only 50%. Those 50% are only aplicable in this way: OCed system takes 50% less time to finish the task. Both are true.


    cadaveca> I only meant that this statement "wPrime, on the other hand, didn't show such significant gains, however still did get a sizable boost." sounds like OCing doesn't provide such a great benefit compared to superPI, but the relative gain is larger. Nothing more. :)

    I was referring to the time saved for myself personally. 5 minutes off of a benchmark repeated a minimum of three times to reduce natural deviations in testing, means that's saved me a minimum of 15 minutes in waiting.


    Pretty impressive gains from overclocking...not the best, performance-wise, for hte platform, but it's pretty damn good considering cost and intended market.

    I knew what you meant, and you know, you're kinda right, and hence my post.

    Is the max TDP on that thing come stock at 111w ? Or is that a result of the OC in that CPU_Z shot at 3.64GHz
