Microsoft will push the Win11 update on October 19 to fix the Ryzen processor L3 latency problem
Microsoft launched a new generation of operating system Windows 11 at the beginning of this month. However, based on the excellent performance of Windows 10 in the past, the new system does not have critical bugs. AMD’s Ryzen processor immediately became the victim. AMD released an announcement earlier that under Windows 11, the Ryzen processor may reduce performance in some applications, and even a 10% or 15% drop in individual gaming games, under normal circumstances, the impact is about 3%-5%.

AMD made a relevant explanation for this performance degradation. The problem is mainly due to two aspects. One type is that the latency of L3 may increase three times, causing some applications that are sensitive to memory and cache to be affected. Games are one of them. The other type is the “preferred core” function, which means that threads are allocated to the two fastest cores, however, in Windows 11, it may not work according to the normal plan. This performance degradation is the most obvious in processors with 8 or more cores and a TDP of 65W or higher.
It’s normal for the new system to have bugs, AMD is definitely not the only hardware manufacturer encountering problems on Windows 11. But a few days after the system was launched, new problems will definitely be discovered in the future. The new system is risky, and upgrades need to be cautious.
