Already when the operating system was released, there was a warning that there would be performance losses on AMD CPUs. With the cumulative update KB5006674 from October 12, 2021, there was then a further deterioration. However, updates with fixes should come next week &#8211; currently Microsoft is already testing the update KB5006746 with insiders.<\/p>\n<p><!--more--><\/p>\n<h2>Performance issues with AMD CPUs<\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" alt=\"\" src=\"https:\/\/vg08.met.vgwort.de\/na\/ed65c4741d444e3999cd1d51b3a5282c\" width=\"1\" height=\"1\">Processor manufacturer AMD had already recently released <a href=\"https:\/\/www.amd.com\/en\/support\/kb\/faq\/pa-400\" target=\"_blank\" rel=\"noopener\">PA-400<\/a>, which contains information about known performance issues that have been reported under Windows\u00ae 11 when running with compatible AMD processors with certain applications. <\/p>\n<ul>\n<li>The AMD CPUs can cause extreme outliers in terms of performance degradation in eSports games, ranging from 10 to 15 percent.\n<li>For applications, AMD says the performance degradation is in the 3 to 5 percent range, as noted.<\/li>\n<\/ul>\n<p>This affects processors supported by Windows 11: all Ryzen CPUs, all Zen+, Zen 2 and Zen 3 CPUs, also the Ryzen 2000, Ryzen 3000, Ryzen 4000 and Ryzen 5000 processors. I had reported in the blog post <a href=\"https:\/\/borncity.com\/win\/2021\/10\/07\/amd-warnt-cpus-laufen-mit-windows-11-bis-zu-15-langsamer\/\" target=\"_blank\" rel=\"noopener\">AMD warns: CPUs run up to 15% slower with Windows 11<\/a>. However, AMD and Microsoft want to fix these performance losses with updates in October.  <\/p>\n<h2>Update KB5006674 increase performance issues<\/h2>\n<p>On October 12, 2021 (Patchday), Microsoft released the cumulative update KB5006674 for Windows 11 (see <a href=\"https:\/\/borncity.com\/win\/2021\/10\/13\/patchday-windows-11-updates-12-oktober-2021\/\">Patchday: Windows 11 Updates (October 12, 2021)<\/a>). This update caused owners of AMD Ryzen processors to experience even higher Level 3 cache latencies than before. The performance, especially in games, drops further. German site heise has covered the topic in detail &#8211; and with measurements &#8211; in <a href=\"https:\/\/www.heise.de\/news\/Windows-11-Erste-Patch-Runde-verschlechtert-Ryzen-Performance-weiter-6216654.html\" target=\"_blank\" rel=\"noopener\">this article<\/a>. There is another discussion on <a href=\"https:\/\/www.reddit.com\/r\/Amd\/comments\/q8t7ce\/windows_11_l3_latency_after_the_last_update\/\" target=\"_blank\" rel=\"noopener\">reddit.com<\/a>.<\/p>\n<h2>Patches for AMD L3 problem coming<\/h2>\n<p>There were already first hints from AMD about upcoming patches to fix the problems, but still without dates. At German magazine heise you can <a href=\"https:\/\/www.heise.de\/news\/Windows-11-Erste-Patch-Runde-verschlechtert-Ryzen-Performance-weiter-6216654.html\" target=\"_blank\" rel=\"noopener\">read<\/a> about a planned Windows 11 update for next Tuesday, October 19, 2021. This update KB5006746 is currently already being tested with Windows 11 Insiders in the Beta and Release Preview Channel (see <a href=\"https:\/\/blogs.windows.com\/windows-insider\/2021\/10\/15\/releasing-windows-11-build-22000-282-to-beta-and-release-preview-channels\/\" target=\"_blank\" rel=\"noopener\">this announcement in the Windows blog<\/a>). The change log says that an L3 caching problem has been fixed. According to heise, a new chipset driver from AMD should follow on October 21, 2021. This should hopefully solve the problems with the performance losses of AMD CPUs in Windows 11.<\/p>\n<p><strong>Similar articles<\/strong><br \/><a href=\"https:\/\/borncity.com\/win\/2021\/06\/24\/yes-microsoft-introduced-windows-11\/\">Yes, Microsoft introduced Windows 11<\/a><br \/><a href=\"https:\/\/borncity.com\/win\/2021\/06\/25\/windows-11-die-hardware-anforderungen\/\">Windows 11: Hardware requirements<\/a><br \/><a href=\"https:\/\/borncity.com\/win\/2021\/09\/17\/windows-11-microsoft-erzwingt-tmp-2-0-auf-virtuellen-maschinen\/\">Windows 11: Microsoft enforces TPM 2.0 on virtual machines<\/a><br \/><a href=\"https:\/\/borncity.com\/win\/2021\/10\/05\/windows-11-offiziell-freigegeben\/\">Windows 11 officially released<\/a><br \/><a href=\"https:\/\/borncity.com\/win\/2021\/10\/07\/windows-11-iot-enterprise-nur-mit-36-monaten-support\/\">Windows 11 IoT Enterprise only with 36 months support<\/a><br \/><a href=\"https:\/\/borncity.com\/win\/2021\/10\/07\/amd-warnt-cpus-laufen-mit-windows-11-bis-zu-15-langsamer\/\">AMD warns: CPUs run up to 15% slower with Windows 11<\/a><br \/><a href=\"https:\/\/borncity.com\/win\/2021\/10\/07\/windows-11-mindestanforderungen-bei-masse-der-hardware-nicht-erfllt-microsoft-verrt-by-passing-trick\/\">Windows 11: Most hardware don't fulfill the minimum requirements, Microsoft reveals by-passing trick<\/a><br \/><a href=\"https:\/\/borncity.com\/win\/2021\/10\/09\/windows-11-memory-leak-im-explorer\/\">Windows 11: File Explorer has a Memory Leak<\/a><br \/><a href=\"https:\/\/borncity.com\/win\/2021\/10\/08\/windows-11-bekannte-probleme-5-oktober-2021\/\">Windows 11: Known issues (October 5, 2021)<\/a><br \/><a href=\"https:\/\/borncity.com\/win\/2021\/10\/12\/windows-11-app-probleme-und-brother-usb-drucker-drucken-nicht\/\">Windows 11: App issues and Brother USB printers doesn't print<\/a><br \/><a href=\"https:\/\/borncity.com\/win\/2021\/10\/13\/patchday-windows-11-updates-12-oktober-2021\/\">Patchday: Windows 11 Updates (October 12, 2021)<\/a><br \/><a href=\"https:\/\/borncity.com\/win\/2021\/10\/14\/windows-11-drucker-probleme-betreffen-mehr-hersteller-und-scan-dokumentsoftware-kompatibilitt\/\">Windows 11: Printer issues affect more manufacturers, and scan\/document software compatibility<\/a><br \/><a href=\"https:\/\/borncity.com\/win\/2021\/10\/16\/icongate-rger-windows-11-die-emojis-und-das-marketing\/\">IconGate: Windows 11, the emojis and Microsoft's marketing<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>[German]Owners of AMD hardware that rely on Windows 11 currently have a difficult time.
