Windows 7 Hotfix Promises AMD Bulldozer Performance Boost

By - Source: Microsoft | B 62 comments

Microsoft has quietly issued a Knowledge Base article that promises greater performance of AMD Bulldozer processors under Windows 7 and Windows Server 2008 R2.

"Currently, the performance of AMD Bulldozer CPUs is slower than expected," the article states, and explains that Windows 7 and Server 2008 R2 do not support AMD's Simultaneous Multithreading (SMT) scheduling feature.

The #2592546 fix solves the problem, according to Microsoft, and boosts the performance of the chip "to the expected performance level". However, as it is a hotfix and not an official patch yet, Microsoft says it may require further testing and only supplies the software upon special request and recommends that it should only be used by those who are "severely affected by this problem".

If that is not the case, the advice is to wait until the next software update is issued. In any case, the hotfix requires an installed Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 Service Pack 1 (SP1).

First tests of the patch reveal a mixed bag of results on AMD's FX-8150 processor. At least those benchmarks suggest that some games will see a slight improvement of performance, while others will decline. The strongest gains are apparently seen in PCMark7 (+14.0 percent) as well as ScienceMark (+10.4 percent).

    Could we get a re-review? I may be an Intel fanboy (admittedly), but I was really surprised at just how bad bulldozed did, it really didn't seem right. I still think the i7 will beat it, but maybe it will outshine the i5 like it should?

    I expect that we won't be seeing the performance that we want until the next version of Bulldozer. I hope that AMD will do well. I have my first ever Intel cpu sitting on my workbench waiting for me to rebuild. I'm not really happy about abandoning my Phenomâ„¢ II X6. In fact I'm actually sad about it.

    Well, by going off of the chart given in the "Reveal" link, the Patch has a total of 36.5% drop in performance with an average of .91% drop per benchmark. More bad over good?

    Reaching for straws. "Anything, anything...just get us some respectable performance."

    Click on the lin, they have the results of the new benchmarks. It's not going to change anything substantially, except benchmarks. Most of the time it hurts performance.

    That's why they pulled it. The hotfix still has a lot of work to be done.

    "Bulldozer FX is underperforming by 40-70%" ???

    I may need to change my selection of best answer?

    "The strongest gains are apparently seen in PCMark7 (+14.0 percent) as well as ScienceMark (+10.4 percent)." Strongest gains are apparently seen in synthetic benchmarks not real world applications way hop aboard the AMD/MS fail train.

    This is only going to increase multithreaded performance. Great to see some increase from this Bullcrapdozer, but it will still have the same major issues with apps that aren't well threaded.

    The update was pulled because it was the cause of some issues? What happened to the other words?

    otacon72, you remind me of game developers that stubbornly refuse to support multicores, insisting that hardware companies should design around software, not the other way around.

    jacekringSo AMD fails to communicate with Microsoft to get their OS's up to snuff with the Bulldozer's new architecture. And the customers are left holding the bag, now M$ is rushing to get a fix out, months after the processor has hit the shelves.Who's fault is it? M$ for not updating their systems? Or AMD for not pushing M$ for updating their systems?

    It's the customers fault for not doing the research before buying.
