AMD releases fix for Ryzen-CCPC2 performance issues on Windows 11

AMD has released a Chipset Driver update that addresses the second performance issue with Ryzen CPUs on Windows 11. In this UEFI CCPC2 issue, the fastest cores were not always picked for tasks.

AMD Chipset Driver version 3.10.08.506 resolves the preferred core issue, AMD writes. In this bug, threads were not always run on the fastest core of the processor. This problem would be especially noticeable with programs that use one or few threads. This would also make the error more noticeable on CPUs with more than eight cores and more than a TDP of 65W, the company says.

AMD indicated more than two weeks ago that performance problems were noticeable with Ryzen CPUs and Windows 11. In addition to the CCPC2 problem, there was also an L3 cache bug. With this error, the cache latency would be three times higher than Windows 10 and that caused the biggest performance issues. For example, esports games could be up to fifteen percent slower with this flaw.

The L3 cache bug should be fixed with a Windows Update. Microsoft previously released a beta update for this, which can now be downloaded as a preview update. With these two updates, all performance issues have been resolved and the CPUs should work as intended, AMD writes.
