Battlefield 3

Its popularity aside, Battlefield 3 may be the most interesting game in our benchmark suite for a single reason: it’s the first AAA DX10+ game. It’s been 5 years since the launch of the first DX10 GPUs, and 3 whole process node shrinks later we’re finally to the point where games are using DX10’s functionality as a baseline rather than an addition. Not surprisingly BF3 is one of the best looking games in our suite, but as with past Battlefield games that beauty comes with a high performance cost

For anyone keeping score, we reran all of our numbers after the recent Battlefield 3 Radeon HD 7000 series performance patch. The results are virtually identical. While we don’t have official confirmation, we believe that DICE switched to a different FXAA codepath; however doing this doesn’t seem to have impacted the performance of the 7000 series, which is either a testament to AMD’s shader compiler, or proof that the overhead from FXAA is very low in the first place.

In any case while AMD’s BF3 performance has improved since the 7970 launch, it’s still one of their weaker games. The 7870 can hang with the GTX 570 at 1920 but the 7850 once more falls behind the GTX 560 Ti. The 7850 in particular just isn’t doing very well here, and it would be necessary to drop down in settings or in resolution to get fluid gameplay out of BF3. However at the same time we do see some further evidence of the impact of having 2GB of VRAM, as both 7800 cards improve relative to NVIDIA’s cards at 2560.

Meanwhile compared to the 6900 series, the 7800 series takes another small lead. At 19x12 without MSAA the 7870 has 5% on the 6970, while the 7850 is effectively tied with the 6950. It’s interesting to note however that relative to the 7950, the 7870 is doing very well here, trailing AMD’s faster card by less than 4%. The fact of the matter is that with the same basic frontend and the same number of ROPs, the 7870’s 1GHz core clock can significantly eat into the performance lead of the 7950 if the 7950 is primarily performance bound by either of those two rendering stages.

    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. :-)

    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.
