In a post published on AMD’s website, the company warns that Ryzen owners who install and upgrade to Windows 11 might encounter instances where their apps slowdown. This is due to a couple of Windows 11 bugs that affect Ryzen processors specifically that cause CPUs to slow down as much as 15%.
It also affects the app’s access to L3 cache by increasing the latency by as much as three times, meaning that apps will take longer to access memory which ultimately affects its performance. AMD has acknowledged the issue and are working with Microsoft to get to the bottom of it.
In a statement made on its website, AMD says, “AMD and Microsoft are actively investigating these known issues for resolution via software updates. This knowledge base article will be updated to include version numbers and delivery vehicle(s) when they are available. In the interim, customers using compatible AMD processors affected by these issues may continue to use a supported version of Windows 10.”
