Microsoft released its first update for Windows 11, causing previous issues with AMD to actually get worse, but it’s aiming to fix the problems soon…
Microsoft just recently rolled out Windows 11 and has also distributed its first update to the new operating system. It comes right after AMD warned consumers that its chips are experiencing performance issues in the same operating system. Basically, it’s affecting Ryzen processors, tripling L3 cache latency, slowing performance by as much as 15% on certain games, causing unnecessary slowdowns.
Microsoft’s First Update to Windows 11 makes AMD CPU Performance even Worse
The second issue affects AMD’s preferred core technology, which shifts threads over to the fastest core on a processor. AMD says this second bug could impact performance on CPU-reliant tasks. The folks over at TechPowerUp measured the L3 cache latency on its Ryzen 7 2700X at around 10ns, and Windows 11 increased this to 17ns. Of course, this isn’t as nearly as efficient.
Fixes for both the Ryzen problems are expected to be available before the end of the month. Meanwhile, the L3 cache issue will likely be addressed by Microsoft as early as next week, probably part on October 19th. The preferred core patch will be addressed by an AMD driver, which is expected to be delivered later this month and will hopefully be available on Windows Update as soon as it’s released.
