OC: Gaming Performance

We’ll keep the running commentary short here, but as we’ll see in our results, power target overclocking alone doesn’t produce a particularly significant result here. Our GTX 660 already runs so close to its maximum boost clock so often that simply allowing it to draw more power doesn’t allow it to clock up all that much higher.

So for significant overclocking we need to turn to utilizing the power target alone with clock offsets. With those offsets in place we’ve increased our power target limits, core clock, and memory clock all by roughly 10%. Overclocked performance as a result is between 8% and 12% better than the stock GTX 660, which for ROP or memory bandwidth-limited game is more than enough to usurp the stock GTX 660 Ti.Meanwhile for games that are heavily shader-bound the 10% overclock will still leave the GTX 660 well behind the stock GTX 660 Ti.

    If i'm a new buyer buying the older 560 at a reduced cost both be a better buy correct?

    While I may be in the minority, I actually check the "The Test" page of every GPU review in order to see which driver version is being used to test the hardware, as well as to get a quick mental list of 2 or 3 GPUs to watch out for in the FPS comparisons.

    Due to this I've noticed for this GPU review many cards are listed that don't appear anywhere in the benchmarks:
    -AMD Radeon HD 6970
    -AMD Radeon HD 7950B (explicitly stated over a non-B)
    -AMD Radeon HD 7970
    -NVIDIA GeForce GTX 570
    -NVIDIA GeForce GTX 670

    (Excepting all the GTX 660 Ti that of course can't be re-tested in time for a launch review, but might be useful as a "factory overclocked options" list for a reader looking at base 660 Ti performance.)

    Thanks for the heads up. I had copied that out of the GTX 660 Ti article and had not yet edited it. It has been fixed.

    Cheers.

    That has the 660 faster than the 7870. Most reputable sites have the card squarely in-between the Pitcairns.

    It appears to me, that we should be glad, that the jump in performance is that low, as finally it seems the power wars of the last generation, when cards were dumping 200 Watts and more into your case, even when they were just higher mid-end cards, are over.
    Now of course that means we get slightly less of a performance boost, but at least power consumption of this card is below the level of a GTX260. That is important, as the 560Ti was relatively quite power hungry, especially once the wick on them was turned up a bit, which was being done quite liberally.
    While the Performance/Dollar metric isn't that great, the performance/(dollar*power) is probably much better than last gen.

    As everyone said it, nVidia is again late to the party. However, both (amd and nV) haven't done anything to improve the price/performance. First the $100 price range, now the 200?

    I'm sorry but since I bought my HD5750 almost 3 years(!) ago for 100 bucks. I dont get much more performance with a similair priced card. Now they are doing it the same to the 200 dollar cards..

    Welcome to the new socialist economy and 4 more years of it.
    Computer prices rise in the new socialist economy.
    LOL
    It's great, maybe AMD will get a bailout soon.

    I saw the big image on the main page and thought it was a projector at first.

    Performance is not bad but the pricing is still too high. Start overclocking a 7870 and the 660 looks bad imo.
