AMD says it observed performance hits of up to 15% on Windows 11-compatible AMD processors when using some applications.
Microsoft and AMD are investigating two separate issues affecting AMD CPUs' performance on Windows 11.
This performance decrease is most noticeable on apps sensitive to the performance of one or a few CPU threads and is more detectable in CPUs with more than 8-cores above 65W TDP. Microsoft and AMD are working on updates to address the performance issues, with an estimated release time later this month.
Microsoft has released Windows 11 worldwide this week and is now rolling it out to new Windows 10 devices and those pre-loaded with Windows 11 via Windows Update.
AMD also published a press release on Windows 11's release day, saying that over 175 AMD CPUs are now compatible with Windows 11.
"AMD Ryzen processors are supporting the new Windows 11 operating system experience, delivering the integration and performance needed to take advantage of exceptionally fast speed, responsiveness and efficiency," AMD said.
