AMD reports that Windows 11 may be causing a performance free fall of aweigh to 15% on Ryzen CPUs
If you have an AMD Ryzen chip in your gaming rig, you may want to wait on upgrading to Windows 11 for a bit. AMD and Microsoft announced that Windows 11 congruous AMD CPUs "may exhibit reduced performance in certain applications when running Windows 11," according to a blog post that our friends all over at Uncle Tom's Hardware spotted.
This means much 100 AMD processors can be affected. According to AMD, one of the issues is the measured and functional L3 latency give the axe nearly threefold, which lowers the performance of certain applications that rely on memory and cache latency, such as games.
The other problem lies with AMD's "preferent core" feature article not functioning as publicized. Preferent Core assigns apps to the fastest core on the bit. This, too, may cause noticeable performance dips with chips that are 65W and high.
Below is the full AMD advisory notice most these two know issues:
| Known Execution Changes | Impact |
|---|---|
| Measured and functional L3 hoard latency may increment by ~3X | Applications sensitive to retention subsystem access time may be wedged. Expected performance impact of 3-5% in affected applications, 10-15% outliers possible in games commonly in use for eSports. |
| UEFI CPPC2 ("desirable core") may non preferentially agenda threads on a processor's quickest heart and soul | Applications sensitive to the performance of same or a few CPU duds Crataegus laevigata demo shrunken performance |
AMD confirms that every Ryzen CPU that's braced by Windows 11 is impacted, along with EPYC and Anthlon chips.
Our testing of a Ryzen 9 5900X on both Windows 10 and 11 showed no appreciable difference in performance, only that is one chip out of more than a hundred on the leaning. (Though we've found other issues that could affect gaming performance on Windows 11.)
Right today nonentity is being rumored happening how Windows 11 is affecting Intel chips, though I'm sure if you're Intel, you're not shedding any tears for the competition.
AMD says both a Windows and software update later this month should firmness the issues. Windows 11 is presently out now as a free upgrade for Windows 10 users. Considering all this, though, you may want to do what some of our readers are doing and wait to make the upgrade.
