Windows 11 is now rolling out to PCs globally, but if you have a device running an AMD Ryzen chip, you may want to avoid being an early adopter of Microsoft's platform. Among the early issues of Windows 11 is a problem with Ryzen processors seeing significant drops in performance.
AMD has confirmed the issue and says users may see performance drops up to 15 percent when running Windows 11.
Working with Microsoft, the company has found there are two causes of the issue. Firstly, Windows 11 could be causing the L3 cache latency to triple. AMD points out this would result in performance drops between 3 and 5 percent on applications, while games could see a drop of up to 15 percent.
It is worth noting AMD seems to be framing this as mostly a problem for gamers, referencing eSports applications as those affected by the L3 cache issue.
Preferred Core Issues
Secondly, Microsoft and AMD say there is also a problem on Windows 11 with the “preferred core” tech used in Ryzen chips. This feature is supposed to move threads to whatever is the fastest core on the CPU. However, it seems this is malfunctioning on Windows 11 and performance issues could be the result for some users.
AMD says CPU-reliant tasks will be most affected by issues with preferred core, especially on Ryzen chips with eight or more cores.
Both companies say they are “actively investigating these known issues for resolution via software updates.” Unfortunately, those updates will not arrive until later this month. So, if you have an AMD Windows machine, it is perhaps best to stick with Windows 10 for the time being.
Tip of the day: If you have an HP, Dell, or Lenovo touchscreen PC, you'll probably want to enable or disable it at various times. Unfortunately, however, many Windows 10 touch screen laptops don't make this easy.
Thankfully, through some tweaks, you can turn off the touch screen no matter your device. In our tutorial, we show you how to disable a touchscreen on Windows 10. We'll also show you to enable it if you wish, which may help if your HP laptop touch screen is not working, the touch screen is not working on your Lenovo laptop, or you're having problems with any other brand.
