Microsoft Releases AMD Bulldozer-Boosting Hotfix

Brad Chacos

Hey, Bulldozer fans: if you’re regular readers of the site you may remember that we told you a few months back that AMD expects to see better performance for its FX chips in Windows 8 , as the company claimed that Windows 7 didn’t handle simultaneous multithreading efficiently. Turns out they were right! Kind of. Windows 7 didn’t handle simultaneous multithreading efficiently, but you still might not see a performance jump in Windows 8 – because today, Microsoft released a hotfix to correct the problem and help Bulldozers run better on Windows 7 and Windows Server 2008 R2.

From the hotfix page: 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 .

So what will the hotfix improve? Again, the web page provides the answer. After you install this hotfix, Windows 7 and Windows Server 2008 R2 fully support AMD Bulldozer CPUs. Therefore, the CPUs operate at the expected performance level .

So, if you have a Bulldozer CPU and a Windows 7 machine, what are you waiting for? Head over to the hotfix page and download the update now !
