Windows 11 is once again throttling the performance of AMD‘s premium Ryzen desktop CPUs.
The feature in question is Windows 11’s thread scheduler, sometimes known as a thread director. It is essentially a small background software that determines which CPU cores should do each task that is supplied to the system. Normally, this would boost performance. However, it seems that the dual CCD configuration of the Ryzen 9 7950X and 7900X is causing issues for the thread scheduler.
AMD Ryzen 7000 performance on a gaming PC running the Windows 11 update 22H2 isn’t what it should be. Through a series of tweets, it draws attention to the fact that the Ryzen 9 7950X, the greatest gaming CPU in team red’s portfolio, performs worse in its default configuration than when half of its cores are disabled, operating on a single CCD (CPU Compute Die).
However, it also looks that turning off AMD SMT (simultaneous multithreading). It is obviously not what should happen, helps to ease much of the performance loss. For the time being, it appears like Microsoft and team red will need to collaborate to fully address the issue.

7700X will offer top notch gaming performance
It’s important to note that because they only feature one CCD, the cheaper Ryzen 5 7600X and fantastic Ryzen 7 7700X chips in AMD’s new lineup are unaffected. Moreover, when comparing price to performance, the 7700X is the best option available. Plus, it is the wisest choice for the vast majority of customers.
This problem has already occurred, previously. In 2021, the 21H2 upgrade for Windows 10 caused Ryzen CPU performance to tank. The problem was resolved by a chipset driver update. If AMD wants to keep gamers from completely avoiding its top-tier chips, it must move quickly to fix this issue.
It is frustrating that this problem has surfaced only days after a different Windows 11 patch was implemented to fix a problem with Ryzen CPUs’ L3 cache latency that was also affecting
