Just released on October 5thWindows 11A new problem was found in.
Some apps may experience performance degradation when using AMD CPUsThere seems to be. AMD and Microsoft are already aware of this issueExpected to be resolved in October updateis.
Problems with L3 cache and CPU core scheduling
According to AMDWindows 11Two performance degradation issues have been identified when using AMD CPUs in… apparently …
The first oneL3 cache latency could be tripledThe problem is that there is.
This can have a significant impact on apps with high memory access and is expected to reduce performance by 3% to 5%.
However, games used for eSports can also experience a 10% to 15% performance degradation.
Another problem isScheduling to allocate threads to CPU cores doesn’t workThat is.
It has been pointed out that this can result in poor performance for apps that make heavy use of one or a few CPU cores without using up multiple cores.
In particular, the impact on performance will be more pronounced on processors with 8 cores or more with a TDP of 65 W or more.
Expected to be resolved in October update
These two problems areBoth are expected to be resolved in an update scheduled for Octoberis.
However, if you are using an AMD CPU and the performance of your computer is important, you may want to refrain from updating to Windows 11 at this time.
Regarding the performance of Windows 11, it has been pointed out that the game performance will be reduced by another security function called VBS.
