AMD warned final week that its chips are experiencing efficiency points in Home 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 larger latency, which implies worse efficiency, after the Home windows 11 replace went stay yesterday.
AMD and Microsoft found two issues with Home windows 11 on Ryzen processors. Home 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 may impression efficiency on CPU-reliant duties.
TechPowerUp measured the L3 cache latency on its Ryzen 7 2700X at round 10ns, and Home windows 11 elevated this to 17ns. “This was made a lot worse with the October 12 ‘Patch Tuesday’ replace, driving up the latency to 31.9ns,” says TechPowerUp. That’s an enormous soar, and the precise kind 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 possible be addressed subsequent week by Microsoft, with rumors suggesting October 19th for a patch. The popular core patch might be addressed by an AMD driver, which is predicted to be delivered later this month and can hopefully be accessible on Home windows Replace as quickly because it’s launched.
It’s nonetheless stunning to see Home 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 impression on key CPUs ought to have been picked up in the course of the months of public beta testing. Both means, it’s encouraging to see this might be fastened very quickly so these affected by worse efficiency received’t have to attend an excessive amount of longer for a patch.
