Some of you may remember that AMD FX processors use a unique dual-core module architecture codenamed "Bulldozer", which current versions of Windows® 7 were not specifically architected to utilize. In essence, for those with an AMD FX-8150 Processor, for example, Windows 7 sees the eight available cores and randomly assigns threads to them.

In initial testing of the upcoming Windows 8 operating system, we've seen performance improvements of up to 10% in some applications, when compared to Windows 7. This is because the system correctly recognizes the AMD FX processor architecture and cores. Thanks to close collaboration between Microsoft and AMD, Microsoft recently completed back-porting some of the Windows 8 scheduler code for AMD FX processors into a hotfix for Windows 7.

So if you have an AMD FX processor, here's what you can do to update your version of Windows 7:

1) Download the scheduler update (KB2645594) and install. This will tell the scheduler that your AMD FX processor contains dual-core modules (in fact this is similar to the SMT path that the other guys use). In essence, threads 1-4 now get assigned to their own module first.

2) Download the core parking scheduler update (KB2646060) and install. This will prevent Windows 7 shutting down unused cores prematurely when there are threads to be assigned (there's a performance penalty parking and then un-parking a core).
I also felt that this required a separate "quote" box:
Quote:
The best possible cases for improvement are applications that use ½ cores in your AMD FX processor. In our testing using the AMD FX-8150 processor, we found the best improvement in wPrime, Left 4 Dead 2, and Lost Planet. Below you'll find links to the patches:
Not much of a performance boost, but hey, it's free! I just hope it doesn't cause any instability issues like the last update.

Like to see how this effects the Crossfire/Sli performance, if it does. To me that was the only thing that let me down with Bulldozer. Wanna go with Tri-fire on my next build coming soon, so hopefully this + Piledriver make me go full AMD XD

1-2% ... wow, that's not even worth the bytes on your HDD... hopefully they can get a decent increase out of these abominations. (Why they didn't shrink phenom II's / thubans i'll never know, those things become monsters past 4Ghz)

So, can we stop hearing the: Wait until there's a patch! It's Windows' fault, not AMD's!

Bulldozer is a disappointment to anyone (including Intel owner's since it won't cause prices to lower) and some people need to admit it.

For those of you who don't like reading or if your wife is about to give birth but you're just doing a quick OCN-check before taking her to the hospital while she's screaming in pain (this of course applies to other medical emergencies as well) :

But heck, it is free performance, and this is the scheduler model that will be used in Windows 8 (along with some further enhancements), so why not add it to your list of downloads?
So... up to 10% improvement in Windows 8 they said a few months ago? I doubt those "some further enhancements" will give 8% extra ...
Not impressed to say at the least. Glad I pulled the trigger on SB and took my loss (sold my CH5F which I bought for BD for a measly € 140, I had paid 210 2 months earlier ).

Linux performance is much better than Windows 8 / Windows 7 hotfix performance still

That's for every CPU though. Hell my N450 is much better in Linux than in Windows except for power consumption.

I hate to sound like an old person here but BD is a server idea that should not have been made into a consumer chip. Not unless they can magically convince everyone to write software in the way to create the software environment the chip was intended for. That combined with the power usage hurt BD.

Now we can fully understand how AMD is 2 years away from Intel.

Those are good processors, indeed, but there are much better out there for the same price.

For having to not infringe on someone else's methods/designs yet still use another's instruction set architecture(x86) I guess it's pretty good. Still it's never going to be what it once was or could be if there were multiple instruction set architectures.

You are delusional. Seriously, seek help.
