    This fix is for improving less-threaded application performance (like f.ex. games)!
    No wonder it has no effect on CineBench@8 threads.

    Yeah, that was two weeks ago, and now the patch is here. The patch itself was released yesterday.

    I'm not surprised that multi-threaded apps son't show much if any benefit. As far as I understand it, the behavior noticed in the FX Overclocknig thread here on TPU, with not all cores scaling up in frequency, is Bulldozer's default behavior. This behavior, without the scheduler update, had some threads running on the lower-speed cores instead of forcing them on the high-speed threads, affecting end results. The patch should have apps like games, that are not using the CPU fully, running on the faster cores when possible.

    must be something wrong with my install, ran my benchmarks, applied hotfix and windows crashed hard, safemode, and restore fixed it , redownloaded hot fix same again.

    Before anyone asks, Retail copy win 7 x64 ultimate, fully updated.

    As for this new performance increase I suspect its only for situational issues.

    Right so my multithreaded performance has gone down, how ever I've had a 7.6% increase in cinebench single core performance.

    Will try more benchmarks.

    By this time, AMD could have made a driver like they did for the Athlon 64 x2, when Windows XP SP2, at the time, couldn't use the two cores effectively.

    So it looks like the mythical Windows speedboost for BD was real after all. If the boost is something worthwhile, then this is excellent news all round, as Intel is gonna get some much needed competition - it doesn't matter which brand one prefers to buy.

    +1 and welcome back. :toast:

    It was never mythical. Some people just love to post negativity and don't have a real grasp on the facts.

    And thank you.

    I seem to be getting the ~same/similar score for Cinebench 11.5 (multi cpu) after updating to the hotfix.

    Orange is after updating the hot fix... Blue is before:

    When I frist heard about it I dismissed it, "some group had found it was a scheduler issue, found a fix that improved some benchmarks by upto 10%"

    No more details were given, sounded a little mythical to me.

    I will find out myself and share but need to get my install fixed as it keeps crashing out on the update.

    The desktop is almost done re installing and then...updates then later tonight I will post as many benchmarks as I can find.

    This changes almost nothing. You cant affect buldys weak IPC. Yes, multithreaded apps will benefit from this, but most important thing remains - with 4 threads active, buldy wont beat similarly clocked X4 phenom. So these are good news for server farm owners and other pros, gamers wont feel a thing.

    If anyone does spot any noticeable improvements please let me know.

    Turbo still doesn't work properly. With my set up.

    I could... but I don't have any Cinebench runs saved from before the hot fix (4 threads) to compare it with?

    Ahhh not to worry then, but yeah this shouldn't really affect things that use 8 threads ( although it has, and negatively for me) will mostly improve single/dual/tri and quad threaded applications.

    Or general system smoothness.

    You don't seems to understand what this patch is about. :slap:
    This patch increase exactly what gamers care about, which is lightly thread performance.

    Right I've rerun cinebench a whole bunch of times now (8 threads)

    And I have definitely lost performance since this patch, it's only a 1.1% difference but that's a difference of

    7.35 prepatch to 7.21 after patch.

    Could disappoint bench markers.

    You can all thank me for spreading this wonderful rumour which I knew was true, but many did not believe me including the Knight Rider Moderator :p

    Anyhow expect a 12% to 20% CPU usage increase via Skyrim, though not sure about performance yet until I get my H100 back from the shop.
