Portal 2

Portal 2 continues the long and proud tradition of Valve’s in-house Source engine. While Source continues to be a DX9 engine, Valve has continued to upgrade it over the years to improve its quality, and combined with their choice of style you’d have a hard time telling it’s over 7 years old at this point. Consequently Portal 2’s performance does get rather high on high-end cards, but we have ways of fixing that…

Portal 2 - 2560x1600 - Very High Quality + 4xMSAA/16xAF

Portal 2 - 1920x1200 - Very High Quality + 4xMSAA/16xAF

Portal 2 - 2560x1600 - Very High Quality + 4xSSAA/16xAF

Portal 2 - 1920x1200 - Very High Quality + 4xSSAA/16xAF

Portal 2 ends up being the strongest lead yet for the GTX 680, with the GTX 680 taking a 17% lead at 2560. What’s especially interesting though is performance in the bonus round with SSAA enabled – the GTX 680 takes a wholly unexpected and completely stunning 44% lead over the 7970. In fact it beats out everything here, including the GTX 590 and Radeon HD 6990. Meanwhile the lead over the GTX 580 is even more amazing, with the GTX 680 leading by 67% at these settings.

As it stands the GTX 680 is the first single-GPU card to do better than 60fps, and it does so in a landslide. All things considered, for a lack of memory bandwidth and ROP changes compared to Fermi GTX 680 does extremely well here.

    Impressive. This cards beats AMD on EVERY level! Price, performance, features, power..... every level. AMD paid the price for gouging it's customers, they are going to lose a ton of marketshare. I doubt they have anything to match this for at least a year. Reply

    The review has been up for less than a minute so you couldn't possibly have read it already. How pathetic is it that you were sitting there hitting F5 repeatedly just so you could get in another "First post! Nvidia is uber!" comment.

    Get a life.

    Haha Creig,

    Good observation, he must of been sitting there spamming to get in that first comment, before he read a word of the review.

    Sour grapes at being banned much, Wreckage ?

    ... but he's correct. The 680 does dominate in nearly every situation and category.

    "the GTX 680 is faster, cooler, and quieter than the Radeon HD 7970. NVIDIA has landed the technical trifecta, and to top it off they’ve priced it comfortably below the competition."

    Obvioulsy Wreckage's analysis of AMD's "price gouging" and prophesies of doom are farfetched...

    Well, yeah, the card does well in most of those tests, but i think it might be a little too far to say that it dominates the 7970 on every level. Reply

    Just finsished looking around various sites and the 680 isnt as good as was suggested.

    Dont forget, you're basically comparing an overclocked Nvidia card to a stock AMD card, and even the base clock is much higher on the nvidia card.

    At the same clocks the results will look much better for AMD. Also, 3 monitor gaming could favour AMD with 3GB of vram.

    Seems like Nvidia really wanted to target the 7970 and the price/performance tag this time, by building a souped up, overclocked Gk104 but its not a 7970 killer. AMD will just need to sell them for $449.

    AMD can stay with the 7970 as planned until Q4 and the 8 series.

    You know clocks aren't the only thing that determines speed? Couldn't one just as easily argue that AMD cards were better because they basically clocked their RAM so high?

    Fact is, at stock, the card beats the 7970 at a lower price. Period.

    You're ignoring the host of factory overclocked models out there that will be quieter than the 680M and perform on a similar level, the price just needs to be dropped. Reply

    Herp derp, the same can be said about Nvidia cards as well. The 680 has tonnes of OC'ing headroom. The GPU boost it has is a messily overclock. Reply

    I guess the lower clocked cores of 470, 480, 570, 580 , and many other Nvidia cards were greatly cheated in all benchmarks because the amd cores were often well over 100mhz higher at stock....
    So we have had at least 3 years of lying benchmarks in amd's favor.
    I'd like to personally thank gamerk2 for this very astute observation that sheds the light of Nvidia asbolutely winning in all the above mentioned nvidia cars for the past couple of years.
    Thank you... (sarc/reality check is free)
