Windows 11’s first replace makes AMD CPU efficiency even worse

AMD warned final week that its chips are experiencing efficiency 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 efficiency, after the Windows 11 replace went reside yesterday.

AMD and Microsoft discovered two points with Windows 11 on Ryzen processors. Windows 11 may cause L3 cache latency to triple, slowing efficiency by as much as 15 p.c in sure video games. The second difficulty 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 efficiency 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 much worse with the October 12 ‘Patch Tuesday’ update, driving up the latency to 31.9ns,” says TechPowerUp. That’s an enormous leap, and the precise sort of difficulty AMD warned about.

Patches for each of the Ryzen points are coming earlier than the tip of the month, although. The L3 cache difficulty will probably be addressed subsequent week by Microsoft, with rumors suggesting October nineteenth for a patch. The most well-liked core patch shall 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 efficiency affect on key CPUs ought to have been picked up in the course of the months of public beta testing. Either means, it’s encouraging to see this shall be mounted very quickly so these affected by worse efficiency received’t have to attend an excessive amount of longer for a patch.
