AMD FX-8150 Tested with Latest Windows Hotfixes, Still No Improvement
German tech website TweakPC did a before-after comparison of applying Microsoft's recently-released KB2645594 + KB2646060 Windows updates, which intend to improve performance of systems running AMD FX processors, by improving the way in which the OS deals with Bulldozer cores, using a top-of-the-line FX-8150 processor. The reviewer put FX-8150 through synthetic tests such as AIDA64 (CPU benchmarks, FPU benchmarks), Cinebench 11.5, MaxxPi (multi-threaded PI calculations), WPrime, Twofish AES, 3DMark (Vantage and 11), ComputeMark; and some real-world tests such as WinRAR, Resident Evil 5, and Battleforge. Barring Resident Evil 5, where the patched FX-8150 produced 4% higher performance and WinRAR, where it produced 3% higher performance, there were no significant performance gains noticed. The review can be accessed at the source.

You will not see an improvement when all 8 threads are used, you will not see a great improvement when 4 threads are used (but there should be some, for cases when the modules were not loaded correctly, although most of the times they were), and you will not see an improvement when just 1 thread is used.
People read the title of the previous article, they saw that "10%", and automatically assumed that it would automagically make the CPU faster. That's not the case. There are just a few situations where the hotfixes will work.
But don't expect it to do better in real world applications that use SSE4.1 which your CPU can't really do for feasible performance gain
It will be fixed with Vishera or by 40h-4Fh Steamroller the SSE2 performance

Below are quotes from another thread, trusted people from this community whom are saying the patch DID improve things. Link: www.techpowerup.com/forums/showthread.php?p=2514812#post2514812
Nothing at 10% thus far but still a wee boost for free aint bad : ]
I wouldn't say it was no improvement due to that website only testing multi-core stuff.
The patch was designed to fix threads jumping from one core to another which should fix up turbocore and the second patch designed to stop processors going into sleep mode whilst a thread was active on them. ( Caused stuttering like effect in games)
That it comes with a lil boost as well is nothing but a good thing.
I have no idea what that is, except any code heavy with these kinds of functions in it will fly on the BD compared to a 2600k. Maybe in the future there will be more such code?
Bulldozer prefers the traditional ideology Integer does Transcoding and it would make sense because there is 2 Integer Pipes per Core(Ignoring the AGLUs which can make it 4) and 3 Integer Pipes per Floating Point Unit
Sandy Bridge aims for floating point to do it....but ultimately it is easier to implement Bulldozer as the best transcoding beast in the world because it is easy to make it transcode and it is very fast at transcoding
Encoding and Decoding <3s Bulldozer as it is pretty much a big DSP
Also FMA can replace a majority of MAC instructions making Bulldozer faster in those areas
