Windows 11 is officially out, but if you have an AMD Ryzen processor, you may want to stop updating a bit: The company reports that its chips may have issues with the new operating system, which may cause performance to drop up to 15 percent in some cases.
AMD and Microsoft have found two major issues with Windows 11 on the Ryzen. The first is that Windows 11 may cause the L3 cache latency to triple. AMD says the problem could cause 3-5 percent poorer performance in most affected applications, while some games (AMD specifically calls them “commonly used for eSports”) could see performance drops of 10-15 percent.
Windows 11 also has issues with AMD’s “preferred kernel” technology, which is usually intended to move threads to the fastest kernel on a processor. AMD warns that users could see performance issues on CPU-dependent tasks, specifically on processors with more than eight cores around 65W TDP.
AMD and Microsoft have already confirmed that they are “actively investigating these known issues through software updates.” The two companies promise that both a Windows update and a software update are scheduled for later this month to try and resolve these issues. But in the meantime, you might want to keep up with Windows 10 until AMD and Microsoft fix things.
