AMD: patches coming for Windows 11 performance issues

After the recent rollout of the Windows 11 update, some users have reported performance issues with certain hardware and software configurations. AMD has acknowledged these issues with some of its processors and has released a support article addressing the performance variations in certain applications on compatible AMD processors when running Windows 11.

According to AMD, the problems stem from how Windows 11 interacts with the L3 cache and AMD’s ‘preferred core’ technology. The company is working closely with Microsoft to address these issues, and a Windows Update is expected to be released later this month to resolve them. For those who are eager for a quick fix, the only suggested workaround is to revert back to Windows 10.

One of the main issues identified is a significant increase in latency in the L3 cache on modern AMD processors, particularly affecting memory-sensitive applications. This can result in a slowdown of 3 to 5 percent in affected applications, with eSports titles experiencing a decrease in performance by 10 to 15 percent.

AMD has not provided estimates on the potential impact of its UEFI CPPC2 (‘preferred core’) technology not functioning correctly in Windows 11. This issue may lead to a disparity in performance between the fastest and slowest cores on processors with more than 8 cores and above 65W TDP. The impact is likely to be more pronounced on processors with a higher core count.

For affected users, it is recommended to wait for the upcoming updates and endure the temporary performance issues. The fixes are expected to be seamlessly delivered through Windows Update, without requiring any additional input from motherboard vendors or BIOS updates.
