New OS Updates and Drivers Address AMD’s Early Windows 11 Performance Woes

AMD has confirmed to us that their early Windows 11 performance issues have been addressed, thanks to OS updates from Microsoft and new driver revisions from AMD. 

Until now, users of AMD’s Ryzen 5000 series processors have not gotten the performance levels that they expected from Windows 11. These performance issues were down to two factors, higher than expected L3 Cache Latencies and non-functional AMD “preferred core” support. 

Windows 11’s latest software update addresses AMD’s L3 cache latency issues, reducing latencies by a factor of three. In many applications, this change will offer users a 3-5% performance increase, while more latency-sensitive applications will see larger benefits of 10-15%. Systems with Windows 11’s Ryzen-fixing update will enumerate KB5006746 in the Control Panel > Programs > Programs and Features > Installed Updates interface.

To restore the functionality of AMD’s UEFI CPPC2 “Preferred Core” function, Ryzen users should install AMD’s latest chipset drivers. The latest version is 3.10.08.506 at the time of writing. This update can be downloaded from AMD’s website here. This update will have a smaller performance impact than Microsoft’s L3 Cache fix, but it will help to deliver optimal performance levels with AMD’s Ryzen CPUs. Every little helps.   

More information about these, now addressed, Windows 11 performance issues is available on AMD’s website.
