Windows 11’s first update makes AMD CPU performance even worse

AMD warned final week that its chips are experiencing performance points in Windows 11, and now Microsoft’s first update to its new OS has reportedly made the issues worse. TechPowerUp reports that it’s seeing a lot greater latency, which suggests worse performance, after the Windows 11 update went stay yesterday.

AMD and Microsoft found two issues with Windows 11 on Ryzen processors. Windows 11 could cause L3 cache latency to triple, slowing performance by as much as 15 % in sure video games. The second concern impacts AMD’s most well-liked core know-how, that shifts threads over to the quickest core on a processor. AMD says this second bug might affect performance on CPU-reliant duties.

TechPowerUp measured the L3 cache latency on its Ryzen 7 2700X at round 10ns, and Windows 11 elevated this to 17ns. “This was made a lot worse with the October 12 ‘Patch Tuesday’ update, driving up the latency to 31.9ns,” says TechPowerUp. That’s an enormous soar, and the precise kind of concern AMD warned about.

Patches for each of the Ryzen points are coming earlier than the tip of the month, although. The L3 cache concern will probably be addressed subsequent week by Microsoft, with rumors suggesting October nineteenth for a patch. The popular core patch will probably be addressed by an AMD driver, which is predicted to be delivered later this month and can hopefully be obtainable on Windows Update as quickly because it’s launched.

It’s nonetheless shocking to see Windows 11 ship with these points, particularly when Microsoft has restricted the quantity of supported processors for this new OS. Bugs at all times occur with new OS releases, however such an apparent performance affect on key CPUs ought to have been picked up in the course of the months of public beta testing. Both approach, it’s encouraging to see this will probably be fastened very quickly so these affected by worse performance gained’t have to attend an excessive amount of longer for a patch.
