Microsoft Posts Correct Hotfix For AMD Bulldozer Processors
Microsoft has posted a hotfix for the core scheduler for AMD ‘Bulldozer’ based processors, including AMD FX series desktop processors. If you’d like to get the most from your AMD ‘Bulldozer’ processor then you need to download two patches:
In initial testing of the upcoming Windows 8 operating system, AMD has 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. This is what the two hot fixes are and you should give them a shot if you are using one of these processors. You can read directions on how to install the patches by following the link below to the forums.
Currently, the CPU scheduling techniques that are used by Windows 7 and Windows Server 2008 R2 are not optimized for the AMD Bulldozer module architecture. This architecture is found on AMD FX series, AMD Opteron 4200 Series, and AMD Opteron 6200 Series processors. Therefore, multithreaded workloads may not be optimally distributed on computers that have one of these processors installed in a lightly-threaded environment. This may result in decreased system performance for some applications.
