AMD 'Bulldozer' gets an Update from Microsoft.

Today Windows updater may have brought "Bulldozer" users a little surprise. A hotfix that increases the AMD flagship processors performance. As this "hotfix" is bleeding edge news any benchmarks have yet to be seen but this confirms Windows 7 was in fact hampering “Bulldozer” from performing at 100% in all prior benches. What percentage it was previously performing at has yet to be determined. Here is a small snippet from the Hotfix release notes.
This article introduces an update that optimizes the performance of AMD Bulldozer CPUs that are used by Windows 7-based or Windows Server 2008 R2-based computers. Currently, the performance of AMD Bulldozer CPUs is slower than expected. This behavior occurs because the threading logic in Windows 7 and in Windows Server 2008 R2 is not optimized to use the Simultaneous Multithreading (SMT) scheduling feature. This feature was introduced in the Bulldozer family of AMD CPUs.
You can download the Hotfix here.

even if it was 5% its better than nothing, at least it shuts up those who said the patch was BS.

Someone with a bulldozer chip do a before and after benchmark and see what you get?

We should be able to get some numbers pretty dang fast here on TPU, plenty of people here have FX's. I sold my Bulldozer rig already so I can't provide numbers unfortunately.

A couple times on GPU I beat the "big boys" to a story. It's not easy. Well done.

Graphics and overclocking don't matter. We want to see a before hotfix and after hotfix.

I'm interested to see an in depth article to see if it actually does anything. Less than 5% takes the piss.

It helps nothing this hotfix

Look at post 3 there is a before and after pic

http://www.octeamdenmark.com/forums/nyheder/9028-microsoft-klar-med-hotfix-til-bulldozer.html
wPrime went down .4 sec, thats an improvement. And it looks like the after tests were 4C and the before were 8C. Not knowing how multithreaded cinebench is but if the scores are the same with 4C off and it is highly multithreaded wouldn't that be considered an improvement?

Looking forward to a professional review site (in English) to test it.

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