Since the Windows 11 update began to turn around at the beginning of the week, some people comment on the impact on performance with certain hardware / software configurations. AMD confirmed that the problems are present with some of its processors and placed support addressing. Changing Windows 11 performance in certain applications on compatible AMD processorsField
Thus, there are problems with how Windows 11 interacts with the L3 cache and how it works with the AMD technology “preferred basic”. AMD assures us that he is working closely with Microsoft on issues, and Windows updating will be delivered to their fight, probably at the end of this month. For patience, only a nuclear version of the return to Windows 10 is offered as a workaround.
The largest of the two problems, in the same way, is that the delay in the L3 cache on modern AMD processors seems triple. AMD says that applications that are sensitive to memory most strongly affect this problem. From a practical point of view, the applied applications will see how processing slows down in an order of 3 to 5 percent. Gamers are better to beware, especially those who enjoy e-sports names, since they, apparently, slow down by 10-15 percent.
AMD does not provide any assessments of the potential effect of the effectiveness of its UEFI CPPC2 technology (“preferred nucleus”), which is working incorrectly in Windows 11. This effect will most likely feel when you have an> 8-core processor with TDP above 65 W, says AMD. With a large number of nuclei, probably, there will be a big difference in performance between the fastest and slowest affordable nuclei.
The injured users of AMD / Windows 11 are probably best recommended to sit tight and quietly, putting lost potential performance in the head. When updates come, you can at least console the relative simplicity of Windows updating, doing your job. Fortunately, these corrections do not need to enter the motherboard suppliers or updated BIOS files, etc.
