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…

We’re just going to jump straight into SSAA here, as even the 7970CF can get 61fps at 5760 with it. This is the first game that the GTX 690 solidly beats the 7970CF for reasons other than bugs; at 5760 with impeccable image quality the GTX 690 is ahead of the 7970CF by 38%, and even at 2560 that’s a 27% lead. In fact you could nearly play Portal 2 with SSAA and with 3D Vision at 2560, at 60fps, if there was even a 3DV monitor at that resolution.

With that said, SSAA really clobbers the GTX 690. This is the worst performance we’ll see relative to the GTX 680 SLI, as the GTX 690 only reaches 93% of the GTX 680 SLI’s performance at 5760, and 90% at 2560. Thankfully for the GTX 690 it’s the difference between 120fps, and more than 120fps.

    The few reviews I've seen have 4GB GTX 680 card between 5% and 10% faster at high resolutions (starting at 2560x1440 to 7860x1600). Adding, on top of that some more memory bandwidth would have been the gaming card most people expected from nVidia.
    As it stands, the GTX 680 is good, but also very expensive (I can have t he 7970 for 65€ less). The GTX 690 is a good product for people who want SLI but don't have the space, PSU, SLI enabled mainboard or want 4 GPUs.

    Sure, link us to a single review that shows us that. Won't be HardOcp nor any as popular, as every review has shown the exact opposite.

    Where are the middle range gpus ?

    Wait. Nvidia don't release them cause they can't provide enough quantities.
  • CeriseCogburn - Thursday, May 3, 2012 - link

    They're being held back like the "real 680" top nVidia core, because nVidia is making more money selling the prior launches and the new 2nd tier now top dog cards.
    It's a conspiracy of profit and win.

    Yes, because making a small number of full size Kepler cores is obviously going to make them more money than a large number of less complex Kepler cores. *rolleyes*

    NVIDIA, assuming they had the ability to get them manufactured in large enough quantities, would make far more profit off a 660 or 670 than they ever would off a 680.

    (I mean making far more profit off the 660/670 series than the 680 series, not specific cards nor the profit per card)

    A lot of prior gen stock moving, take a look you're on the internet, not that hard to do, wonder why you people are always so clueless.

    For instance the entire lot of 7870's and 7850's on the egg are outsold by a single GTX680 by EVGA - confirmed purchasers reviews.
    So it appears nVidia knows what it's doing in a greatly superior manner than your tiny mind spewing whatever comes to it in a few moments of raging rebuttal whilst you try to "point out what's obvious" - yet is incorrect.

    Ditto.

    Every time my Anandtech feed updates, the first thing I'm hoping to see is reviews for the more-reasonably priced, and less power-hoggy GTX 640 (w/GDDR5) and GTX 660 Ti. If we see a review, then at least we know it'll show up at retail very soon after.

    All I want for xmas is a mid-range NVidia card with a higher idle wattage to maximum performance ration than AMD (because NVidia > AMD wrt drivers, esp under linux).
  • zcat - Thursday, May 3, 2012 - link

    correction: idle Watts <= 10 && max performance >= AMD.
