Windows 11 update fixes performance issue for AMD processors

Windows 11 and AMD processors
Written by Emma Davis

Microsoft continues to struggle with bugs in Windows 11 – the company released Windows 11 preview build 22000.282, which fixes performance issues in AMD processors and a bug that caused the taskbar to look exactly the same as in Windows 10.

The build is already available to members of the Windows Insiders program in the Beta and Release channels, and updates will be available to ordinary users before the end of this month.

Let me remind you that at the beginning of this month, AMD warned users that processors compatible with Windows 11, when using some applications, may experience a decrease in performance by up to 15%.

The speed of some applications in Windows 11 dropped by 3-5% on average, but in esports games there could be a 10-15% slowdown.AMD specialists write.

Worse, with the recent release of KB5006674, which fixed Intel Killer and Dell SmartByte issues, AMD CPU performance in Windows 11 has deteriorated even more: according to TechPowerUp, L3 cache latency on Ryzen 7 2700X has increased from 17.1 ns to 31.9 ns. (after a simple installation of Windows 11, the latency increased from 10 ns to 17.1 ns).

Microsoft has now fixed the L3 cache issue in Windows 11 22000.282, however there is no fix yet for the second issue, which is linked with the fact that UEFI CPPC2 does not route tasks and threads to the fastest processor core.

Microsoft and AMD developers in the near future promise patch for this bug, which also slows down AMD processors, in the nearest future.

Also with the release of Windows 11 22000.282, another annoying bug was fixed, due to which the Windows 10 taskbar did not update to the new version (centered by default) and remained the same.

Unfortunately, these are not all bugs in Windows 11. Let me remind you that the company’s engineers are working on fixing the problem with registry keys that use non-ASCII characters; various compatibility problems (for example, Brother printers cannot work normally in Windows 11); and numerous printing problems, such as those that arise when clients and print servers are in different time zones.
