AMD, Microsoft Deliver Windows 11 Performance Fixes

Earlier this month, we learned that AMD-based PCs that were upgraded to Windows 11 suffered from a 3-15 percent performance hit. Well, good news: AMD has fixed the issues.
“AMD and Microsoft have determined that compatible AMD processors may exhibit reduced performance in certain applications when running Windows 11 build 22000.194,” an AMD support page notes.
There were two issues, an L3 cache latency problem that impacted performance by 3-5 percent, and a UEFI CPPC2 (“preferred core”) scheduling issue that impacted performance by 8 to 15 percent.
But both are now fixed, one via a Windows 11 cumulative update preview and one via an AMD-issued Chipset Driver package.
