AMD 'Bulldozer' gets an Update from Microsoft.

TheMailMan78 · Dec 15, 2011

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.

great news, someone get the benchmarks on.

brandonwh64 · Dec 15, 2011

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

johnnyfiive · Dec 15, 2011

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.

bear jesus · Dec 15, 2011

I look forward to seeing what difference it makes.

phanbuey · Dec 15, 2011

I would really love to see some benchmarks of how this performs.

JustaTinkerer · Dec 15, 2011

Just yesterday I was saying this didnt exist, I need to learn to stfu, hat eating time.

I only have novabench on my PC.

What tests you wanna see done? mind no graphics stuff as Im running on a 3850 crossfire setup right now and no overclocking results as im on stock till my new water pump come in.

I have the hotfix just not installed it yet

pantherx12 · Dec 15, 2011

Right think I got it now so will install, anyone want to send me links to benches to run, already have cinebench.

HossHuge · Dec 15, 2011

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

fullinfusion · Dec 15, 2011

Shit! I sold my BD to Paulieg... I hope he can run it and show me some numbers... I have some before numbers but need the numbers after the hot fix.

JustaTinkerer · Dec 15, 2011

Downloading PCmark vantage 10 min to go

phanbuey · Dec 15, 2011

Please post some benchies before and after if you can! txs

pantherx12 · Dec 15, 2011

So far I'm getting lower scores.

Great hot fix Microsoft!

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

I swear that's the second post :laugh:

If anything they've got a performance hit look at the small box that's some kind of memory test/compression test ?

Same performance hit here.

Bloody hell did microsoft even test these? :laugh:

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?
