If you run them Windows 11 into a Ryzen chips from AMD, be prepared for small reductions in its performance.
ΗAMD says it has revealed a mysterious issue about its processors that it may cause "Reduced performance in some applications" in Windows 11, which were released on Tuesday, October 5.
The support document of the chip manufacturer indicates that all processors are affected AMD which are officially compatible with Windows 11. For consumers, these chips are included in the range Ryzen 2000 of 2018.
One of the problems discovered can be caused by cache L3 in AMD chips to potentially increase the latency three times. Thus, its deceleration L3 memory may delay access times for some applications. “Expected performance impact 3-5% in applications that are affected ", wrote the AMD in the support document. "It's possible up to 10-15% in games commonly used for eSports».
The second issue concerns the system "UEFI CPPC2»Of the chip, which can communicate with the operating system about which CPU cores are most capable of achieving high push speeds for a particular task. For some reason, the UEFI CPPC2 will not always be in to «preferably program the threads in the faster core of the processor»While the Windows 11, says AMD. As a result, the problem may cause a performance slowdown, especially for single-threaded programs.
"Applications sensitive to the performance of one or more CPU threads may experience reduced performance," the company added. "Impact on performance can be more detectable on processors with less than 8-cores above 65W TDP».
Maybe it's better to wait until you install them Windows 11 until the errors are corrected. Fortunately, the AMD and Microsoft are preparing corrections for both problems, which are expected to arrive later this month.
