A Hot Potato: As usual, Microsoft released Windows 11 before making sure there were no major issues affecting the overall experience. Fortunately, this version is obscure, but early adopters of AMD may have lower gaming performance than Windows 10. This issue will be resolved this month with a software update.
Windows 11 has only been available for a few days, and we're already seeing problems with Microsoft's new operating system. Some of them are incompatibility issues with some network software or applications such as Oracle VirtualBox, as well as the common types of errors that come with almost every new version of Windows.
However, according to an AMD blog post (thanks, Tom Hardware), people upgrading to Windows 11 on a Ryzen-based system will experience lower performance in some scenarios. The performance drop in most apps will be in the range of 3 to 5 percent, but the company found in testing that you can see a performance drop of up to 15 percent in some popular eSports games.
This issue affects all Ryzen and Athlon processors supported in Windows 11, including about 100 models of the Ryzen 2000 series, Ryzen 3000, Ryzen 4000, and current AMD Ryzen 5000 series processors, EPYC says its datacenter processors are affected. Threadripper processors also for workstations.
AMD explains that this is a two-way street. First, the company realized that Windows 11 could triple the performance of L3. The second is related to a feature called UEFI CCPC2 (aka "preferred kernel"), which usually program threads onto the fastest CPU cores. In the beta version of Windows 11, this does not work as planned and mostly affects the performance of processors with eight or more cores and a TDP of more than 65 watts.Read more: Windows 11 review: Better than Windows 10, but still in development
For now, Microsoft and AMD are recommending a supported version of Windows 10. Both companies are working on software issues that will be addressed in later this month.
