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.

    Last page: Based on our benchmarks we’re looking at 95% of the performance of the GTX "580 SLI" - 580 SLI should read 680 SLI.

    I wish there was a separate button to point out this sort of thing so they could silently correct it. Dont get me wrong, I think its good to have accurate information, just clutters things up a bit.

    p 2

    While the basic design of the GTX 690 resembles the GTX 590, NVIDIA has replaced virtually every bit "with plastic with metal" for aesthetic/perceptual purposes.

    surely "with plastic with metal" to "of plastic with metal"

    still a good review

    1st line on page 2 "Much like the GTX 680 launch and the GTX 590 before it, the first generation the first generation of GTX 690 cards are reference boards being built by NVIDIA"

    First generation has been written twice.

    The first benchmark plotted (Crysis) has a resolution of 5760 x 1200, this has to be wrong!

    It's crazy but right. He tested that resolution on multiple games.

    If you look at accumulated benchmarks across the web, the 680 Nvidia cards beat the 7970 amd cards by a much higher percentage in 1920x1080 (17.61% ahead) than they do in 1920x1200 (10.14% ahead).
    This means anand reviews always tests in 1920x1200 to give the amd cards a prettier looking review, instead of testing in 1920x1080 (the most commonly available resolution at 1920x that they could easily set their 1920x1200 monitors to).
    Hence their tests here at anand are likely also amd favorably biased in higher resolutions.

    It's not like 19x12 is an uncommon or unavailable resolution. Maybe Nvidia should improve their 19x12 performance?

    Sadly, it is a very uncommon resolution for new monitors. Almost every 22-24" monitor your buy today is 1080p instead of 1200p. :(
