    You've landed on the AMD Portal on AnandTech. This section is sponsored by AMD. It features a collection of all of our independent AMD content, as well as Tweets & News from AMD directly. AMD will also be running a couple of huge giveaways here so check back for those.

Gaming Performance

Our latest discrete GPU gaming tests use a GeForce GTX 680, while the older tests use the Radeon HD 5870. We're focused on looking at differences between CPUs here so most of the numbers you see are CPU bound rather than pushing the GPU to the limits. As most games are at best a mixture of single and lightly multithreaded workloads, AMD's FX platform doesn't do well here at all. If you're looking to build a high end gaming machine and want the best CPU for the job, Vishera isn't it.

    Prognosis for the near future is that having that many threads will still not be a whole lot of use for gaming. See Amdahl's law for why. Reply

    It's safe to say all programs/games going forward will take advantage of four cores or more. Battlefield 3 released LAST year and basically requires 4 cores in order to be GPU-limited (as in the game is CPU limited with just about any videocard unless you have 4 cores. Reply

    Prognosis for the near future is that having that many threads will still not be a whole lot of use for gaming. See Amdahl's law for why.

    Amdahl's Law is not a reason. There is plenty of task parallelism to exploit. The real issue is ROI, and there's two aspects to that. One is that multi-threaded development is freakishly hard. Unlike single-threaded development, you cannot know exactly what each thread is doing at any given time. You need to synchronised to make certain actions deterministic. But even then you can end up with race conditions if you're not careful. The current synchronization methods are just very primitive. Intel will fix that with Haswell. The TSX technology enables hardware lock elision and hardware transactional memory. Both will make the developer's life a lot easier, and also make synchronization more efficient.

    The second aspect isn't about the costs but about the gains. It has taken quite a while for more than two cores to become the norm. So it just wasn't worth it for developers to go through all the pain of scalable fine-grained multi-threaded development if the average CPU is still only a dual-core. Haswell's TSX technology will come right in time as quad-core becomes mainstream. Also, Haswell will have phenomenal Hyper-Threading performance thanks to two nearly symmetrical sets of two integer execution units.

    AMD needs to implement TSX and AVX2 sooner rather than later to stay in the market.

    Nice post. Appreciate it.

    And ouch for amd once again.

    No, gaming won't need that many threads in the near future either. Nobody is going to make a game demand more than 4 threads because that's what common gamer systems support. Reply

    I disagree. Say we have a hypothetical game that support 8 threads. The overhead of over-threading in a quad core system is frankly, not very much, while it may provide improvements on people with octocore or Intel processors with hyper-threading. Reply

    In fact, there are many games nowadays that split workload into many threads for economic simulation, background AI planning in user phase, physics, audio, graphics subthread, network management, preloading and resources management. It is just that even with the parallelism, there bound to be bottlenecks in single threading that a 8 core may not benefit at all compared to 4 cores.

    So I disagree, it is not about people not spending resources in making parallelism or not supporting it. It is the nature of the workload that is the determining factor.

    LOL- amd sucks period, did you look at the gaming page ?
    these visheras got literally stomped to death

    AMD fanboy = the imaginary, non existent, and never to exist future looks glorious for de furhor amd!

    What a one dimensional computer enthusiast you are. You spend hundreds to play games on a computer when you could do the same ona console for less?? I use my computer to gain knowledge, impart knowledge, do organizing work to liberate the working class from wage slavery, write leaflets, an documents. I occasionally play strategy games that are usually multi-threaded, like Galactic Civilizations II. . There is no greater value on the planet than the FX processors for what I do. They save me time for the work I do over the Intel processor in the $200 price class. Time and money that's important , frame rates of a 120 are useless but too the over-privileged who buy 120 mhz monitors for their gaming. What a waste of money and resources that could be used for the advancement of human kind. Reply

    "Value" is more than just perf per purchase dollar, running costs also need to be included.

    E.g. a basic calculation based on the charts above the FX CPU I've saved $50 on would cost 2c extra per hour at full load in power. So 2500 hours at load would be my break even point. That's 7 hours a day at full load over a year, a heavy use scenario but quite possible.

    Multithreaded games are such a vast exception to the rule (that once you have "enough" CPU power you gain infinitessimal fps from more) they are not worth even mentioning.
