If you have an AMD Ryzen CPU, you might want to wait a little while longer before upgrading to Windows 11: the company is reporting that its chips might have issues with the new OS that could cause performance drops of up to 15 percent in some cases.
Why does the performance problem occur between Windows 11 and AMD Ryzen?
There are two primary problems with Windows 11 on Ryzen that AMD and Microsoft have discovered:
The first is that Windows 11 may cause L3 cache latency to triple. According to AMD, the problem may result in 3–5% worse performance for most affected applications, while some games (AMD specifically name-checks “commonly used for eSports”) might suffer with 10-15% decreased performance.
AMD’s “preferred core” technology, which is frequently used to move threads to the fastest core on a processor, has been having problems with Windows 11. Users who have AMD processors with more than eight cores and a 65W TDP may experience problems running CPU-reliant activities, according to AMD.
AMD and Microsoft have already confirmed that they are “actively investigating these known issues for resolution via software updates.” Both firms promise that a Windows upgrade and a software update will be released later this month in an attempt to fix those issues. However, in the meantime, you may want to stick with Windows 10 until AMD and Microsoft resolve their issues.
