AMD addressed a performance event affecting systems running Windows 11 on AMD chips.
The fix comes with AMD Ryzen Chipset Driver release 3.ten.08.506.
Microsoft fixed a separate issue affecting AMD chips running Windows 11 earlier this week.

AMD released a chipset commuter to address performance issues affecting PCs with AMD chips running Windows 11. The update fixes an issue that affects AMD'southward preferred core applied science, which shifts threads to the fastest core on a processor. Affected PCs saw performance drops, causing frustration amid gamers. Microsoft as well fixed a divide issue that affects AMD processors running Windows xi.

AMD outlines the set for the issue related to its preferred core technology as well equally Microsoft'southward earlier fix for the L3 caching issue:

Known Performance Changes	Impact	Resolution
Outcome 1: Measured and functional L3 cache latency may increase for some applications.	◦ Applications sensitive to memory subsystem admission fourth dimension may exist impacted. ◦ Estimated functioning impact of [less than] 3-five% in affected applications, with possible outliers in some games.	◦ A Windows eleven software update is now available to address this issue under Microsoft Knowledgebase ID 5006746. ◦ More information on downloading and installing this update tin can be obtained nether Microsoft article KB5006746. ◦ Systems with this update practical will enumerate KB5006746 in the Command Panel > Programs > Programs and Features > Installed Updates interface.
Issue 2: UEFI CPPC2 ("preferred core") may non preferentially schedule threads on a processor's fastest core.	◦ Applications sensitive to the functioning of one or a few CPU threads may exhibit reduced operation. ◦ Performance impact may be more detectable in >8-core processors above 65W TDP.	◦ An AMD Chipset Driver package is now available to address this effect under version three.10.08.506. ◦ Systems with this update applied volition written report AMD Chipset Software 3.10.08.506 (or newer) within the Apps & Features interface of Windows xi. ◦ In improver: ◦ For AMD processors with the "Zen 3" architecture: Systems configured with AMD Chipset Driver 3.ten.08.506 (or newer) should study version 7.0.3.v (or newer) for the AMD.Power.Processor.Settings entry in the Windows eleven Provisioning Packages interface. ◦ For AMD processors with the "Zen+" or "Zen 2" architectures: Systems configured with AMD Chipset Driver 3.10.08.506 (or newer) should accept the AMD Ryzen™ Balanced power program selected and agile in the Control Panel > Ability Options interface.

With both of these fixes, AMD-powered systems should evangelize expected performance when running Windows 11.
