The first Windows 11 update has just become available, but AMD users will have to wait at least another week in hopes of fixing the Ryzen L6 cache issue. It is being reported that the first official Windows 11 update somehow actually made the Ryzen L3 cache latency even worse.
Microsoft and AMD said last week that some of the company’s Ryzen CPUs could take a performance hit of up to 15% on certain games when upgrading to Windows 11. Well, according to this report from TechPowerUp, testing has shown that there is an increase in L3 cache latency for some Ryzen CPUs. After Tuesday’s patch goes live. According to a Microsoft blog post, Windows 11’s October 12 update (KB5006674) mainly handles a few minor security updates. There’s even a helpful video that dives deeper into the update.

Enterprise customers running Threadripper and EPYC workstations can request the patch soon.
