The question is not yet completely decided, but if in doubt, refrain from updating your operating system.
Available for only a few weeks, AMD's new Ryzen 7000 processors don't seem to be working as well as the American firm would have liked. The cost of the new AM5 platform - which is inseparable from the processors - is particularly at issue, as it involves the purchase of a new motherboard and DDR5 RAM. AMD would have even decided to reduce its production of microprocessors to avoid overstocking and this concern with Windows 11 is not to arrange AMD's business.
Something interesting I've noticed as I updated all our CPU data with the RTX 4090 is that there are now many instances where single CCD Ryzen CPUs are faster (better for driving high fps). Previously the R5 3600X never really beat the R9 3950X for example, where as now it does.

Indeed, as Neowin explains, it seems that the management of CCD(CPU Compute Die, specific to Ryzen processors) is not free of reproach when the 22H2 update for Windows 11 is installed. The CapFrameX tool has thus made it possible to highlight the fact that in certain cases, disabling a CCD is beneficial to the processor. Remember that a CCD is a cluster space within the Zen 4 architecture used on the Ryzen 7000. In the case of the Ryzen 9 7950X, a CCD groups together eight cores and, with the two CCDs, we arrive at the sixteen cores proposed by AMD. However, under Windows 11 22H2, having only eight cores sometimes allows you to get better performance... It's the world upside down!
This problem is all the more annoying because it doesn't only affect one unlucky person and seems to affect ALL users of Windows 11 on Ryzen 7000 who have patched their operating system. Worse still, according to some sources, the problem has also been reproduced on older Ryzen processors such as the 3000 series. We can imagine that AMD as well as Microsoft are taking the matter very seriously, but neither company has made any statement for the moment. Let's hope things don't drag on too long and, in the meantime, as we said in the introduction, we invite Ryzen-equipped Windows 11 users not to install the 22H2 update.
