You can see more of the changelog here (opens in new tab).AMD Chipset Driver 18.50.16 is an AMD update that is explicitly designed for ASUS users.

Addresses an 元 caching issue that might affect performance in some applications on devices that have AMD Ryzen processors after upgrading to Windows 11 (original release).

Here's the AMD and Microsoft changelogs on the respective updates: AMD Chipset Version 3.10.08.506 Changelog:ĪMD Ryzen™ Power Plans (required for UEFI CPPC2 support with “Zen+” and “Zen 2” in Windows® 11)ĪMD Ryzen™ Power Provisioning Package (required for UEFI CPPC2 support with “Zen 3” and later in Windows 11) We'll circle back with updated testing soon.

In addition, select AMD EPYC processors for data centers and some newer Athlon chips are also impacted.Īs mentioned, we've already shared plenty of performance testing that shows the impact of the Windows 11 bugs. That means all Zen+, Zen 2 and Zen 3 CPUs that comprise the Ryzen 2000, Ryzen 3000, Ryzen 4000, and Ryzen 5000 processors. That raised concerns that the bug could possibly result in unfair comparisons, particularly if the second patch didn't arrive in time for reviewers to incorporate into their launch-day testing for Alder Lake. The availability of both patches allays those fears.īoth bugs impact every Ryzen CPU supported in Windows 11. Making things worse for AMD, Windows 11 has new scheduler optimizations specifically for Alder Lake, so reviewers will use the new operating system for testing.

The bugs couldn't come at a worse time: Intel is on the cusp of launching its seemingly potent Alder Lake chips that will undoubtedly tighten the race for desktop PC supremacy. AMD says the performance reduction may be more noticeable in chips with more than eight cores and a >65W TDP rating, but the patch released today will correct those issues.

This bug primarily impacts performance in lightly-threaded applications. The first patch fixes AMD's UEFI CPPC2 (Collaborative Power and Performance Control 2) feature, also known as the 'preferred core' technology that helps steer lightly-threaded work to the fastest cores on the chip. As a reminder, the bugs impact all Windows 11-compatible AMD processors. The second patch comes from Microsoft as a Windows update that arrived today. Naturally, all users on Windows 11 platforms should update to the new patch immediately - you can find the new driver here. The first patch comes from AMD in the form of a chipset driver that fixes the UEFI CPPC2 driver that's responsible for steering threads to the correct cores. AMD has also confirmed to Tom's Hardware that it has released a patch for one of the two bugs that lead to reduced performance in Windows 11 and impact the Best CPUs for gaming.
