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 ends up being at about the middle of the road as far as performance goes. The 7870 enjoys a smaller lead over both the 6970 and the GTX 570, while the 7850 takes one of its biggest losses versus the 6950 and GTX 560 Ti at around 3-5%. The good news is that at these performance levels, performance is good enough for the SSAA bonus round, which sees the 7870 hitting just shy of 60fps. The 7850 on the other hand only falls further behind the GTX 560 Ti with SSAA, and at 45fps probably isn’t going to be quite fast enough to make the cut.

    Or don't. It's not on sale for 2 weeks yet. Reply

    NOT with 1/16 the FP64 performance. Reply

    FP64 is useless for games for the foreseeable future. Reply

    I love the "further image quality improvements page" which delicately and carefully explains how amd did a wonderful job of making things better as the image quality degrades...
    After noting the degredation very, very lightly and tossing out the problem, it is declared "unnoticable" for "all intents and purposes".
    Eventually amd's IQ is going to be so far behind nvidia's the endless denials and it doesn't matters - will just continue since amd can crank an extra 20 fps doing it...
    LOL
    A "gift" from amd.

    Article: " As AMD began winding down Cayman (6900 series) almost immediately with the launch of the 7900 series, at this point the 6900 market has effectively dried up. Having taken themselves out of competition with themselves, AMD’s only competition is NVIDIA’s lineup."

    And there we have it - AMD and their evil plot to squeeze every last dollar out of those "they care about", the gamers...
    I don't want to hear Nvidia is evil anymore.
    Time to look in the mirror amd users.

    Furthermore, it's time the reviewers start slamming AMD the way they slam Nvidia, in this case, one can consider it PRAISE for AMD "drying up their own card channels"- and if that isn't bias I don't know what is.

    These cards don't seem like such a wonderful value considering what the 6900 series was offering, but since those cards have gone poof, I guess you'll have to settle for the 7800 series? It really just seems like they are adjusting their pricing scheme to be less compressed than it was before.

    TL: DR; If you've got a 6900 series card, the 7000 series is not for you.

    I still have my wonderful 5870 I purchased in 2009 (which now is not far from 3 years ago...), and still waiting for something that offers more performance than the 7970. Com'on Nvidia! Blow everything out of the water please.... Reply

    "TL: DR; If you've got a 6900 series card, the 7000 series is not for you."
    I'd say the 30 to 50% increase of the 79xx to 69xx cards could be well worth it. However, unless you run a multi-monitor setup or have a 2560 resolution, you really should think twice about spending that amount of money on these cards. But I guess people with that kind of cash can either do their own thinking or don't have to care too much about spending and can afford to "BUY ALL THE CARDS".
    I'm still running a HD5770 and have a newly acquired 27" monitor here that is really stressing it. I think I'll go for a 78xx and later upgrade to CF because my 550W PSU can handle it with these cards, whereas HD69xx would be stressing it too much. :-)

    "TL: DR; If you've got a 6900 series card, the 7000 series is not for you."

    Thats the dumbest statement I have ever read here. The 7970 is DOUBLE the performance of the 6970 with overclocking. Even the $250 7850 beats the 6970 with overclocking.

    The 7 series is the biggest performance jump over the previous series since I have followed graphics cards, since 1998.
