Microsoft Releases Hotfix to improve AMD Bulldozer performance

[Indudep]

From the past several months the AMD looking forward to get more and more performance for its FX chips in Windows 8. Before hand the problem was that the Windows 7 wasn’t capable to handle simultaneous multithreading competently. No matter what it is, we still not see any kind of performance improvement in Windows 8. Now the tension gets resolved because the Microsoft released a hotfix for AMD Bulldozers so that it can run better on Windows 7 and Windows Server 2008 R2 and perform multithreading efficiently.

Microsoft released a patch that improves the performance of the AMD Bulldozer. In particular, the update instructions to enable support SMT (introduced with the new processors bulldozer) doing encode a very interesting performance increase. A few hours after the release of this patch was immediately withdrawn and now is no longer available for download. For its part, AMD said it would be two patches in the pipeline for Windows 7 systems can significantly improve the performance of Bulldozer processors.

The hotfix fixes problems with AMD's Bulldozer in Windows 7 with the imported function SMT Parking. This feature was developed by Intel and Microsoft for the utilization of the Hyper-cores of Intel CPUs as well as to control the upshift in the turbo-boost. This was for Windows 7 so that only the physical cores are loaded and only then the hyper-cores on a quad core with hyperthreading. If the system was not operating at full capacity, which in most private system is probably the case, the CPU could not deliver full power.

AMD and Microsoft are working continuously to improve the hardware and software for our mutual customers. As part of work together to optimize the performance of" Bulldozer "architecture of AMD-based processors that work on an update to the code programming Windows 7-based. The code associated with this KB is incomplete and should not be used.

AMD was surprised at the decision to publish the Microsoft patch that would not allow users to enjoy full performance of its new CPU. According to various tests, in most cases there is no noticeable change. In some cases, the user is a winner, in others it loses. The publication was not expected until the first quarter of 2012 and will consist of two successive updates; the second is not ready yet.

The update should include collaboration with Bulldozer improve SMT method. The performance of AMD's latest flagship processor, the FX series with AMD's new Bulldozer architecture board, but fell against in countless reviews. That was partly due to the way Windows tasks to the available threads in the Bulldozer processor assigns. Bulldozer uses modules with two partial cores, Windows could not properly handle the new SMT feature.

From the benchmarks, I think that they should lead to the hotfix as well not have an opinion. And it remains controversial, whether you're a Bulldozer module with a single core SMT should call or a dual core with shared resources. In the first Sun Niagara processor made neither the shared FPU nor that the entire single-core CPU suddenly as it was dubbed, and that would also not be valid.

Microsoft has made available to users with the new AMD Bulldozer a specific patch that will provide a significant performance boost, especially in the management of threading in applications that make intensive use of multithreading features.

The ultimate solution for AMD was lacking especially in the management of threading because it was not optimized for the functions SMT, simultaneous multithreading (SMT).

With the patch released Windows can manage each block as single dual-core multi-threaded cores; as if the CPU has 8 cores had become a quad core with eight threads. The results of this training is to be practical, in fact, according to preliminary information scattered in the forums, the improvements seem to be obvious, especially in 3D applications such as games.

The product is just fine, maybe they have something Microsoft too little time given to developing such an update, or Microsoft is just too slow. The problem is indeed with Windows, and not the AMD Bulldozer.
