微软将在将在10月19日的Windows Update通道释放L3缓存问题补丁，解决AMD Zen+二代锐龙 cpu安装win11系统性能损失3~15%的问题
The performance of AMD Ryzen platform deteriorated significantly after it was upgraded to Win11: Microsoft completed the repair within this month. On the 5th of this month, the first official version of Windows 11, Build 22000.194, was pushed online.
However, AMD soon stated that it found that some Ryzen platforms had compatibility problems with Win11, mainly related to L3 cache delay and process scheduling. The former will affect applications sensitive to the cache and memory subsystem, and the performance may be lost by 3-5%. Some e-sports online games may be as high as 10-15%.
Although the actual test shows that the difference between the real game play is not so huge, it is a "heart disease" that lingers on some users after all.
The latest news stated that the above-mentioned problem has been resolved. Among them, the L3 cache problem patch will be released in the Windows Update channel on October 19th, and for the UEFI CPPC problem, AMD will release the driver power patch from October 21st.
The so-called CPPC is mainly used to turn on the processor performance autonomous mode. It is relatively large for notebook product users and can ensure that high-load tasks are scheduled to be executed by the gold standard core when the power is connected.
In addition, the main affected are Zen+ and later Ryzen, that is, the second-generation Ryzen and newer.

AMD锐龙平台升Win11后性能大幅劣化：微软本月内完成修复 本月5日，Windows 11首个正式版Build 22000.194推送上线。
但很快AMD方面就表示，发现部分锐龙平台与Win11存在兼容性问题，主要涉及L3缓存延迟及进程调度，前者将影响对缓存、内存子系统敏感的应用，性能或损失3-5％，部分电竞网游可能高达10-15％。
虽然实测显示，真正玩起游戏来差异没有如此巨大，但毕竟是萦绕在部分用户的一块“心病”。
最新消息称，上述问题已经解决。其中L3缓存问题补丁将在10月19日的Windows Update通道释放，UEFI的CPPC问题，AMD将从10月21日开始下发驱动电源补丁。
所谓CPPC，主要用于打开处理器性能自主模式，它对笔记本产品用户较大，可以确保在接入电源的情况下，把高负载任务安排由金标核心执行。
另外，此次受影响的主要是Zen+及之后的锐龙，也就是二代锐龙及更新。
