First Windows 11 Patch Makes AMD Ryzen Bug Worse – But a Fix is on the Way!

Earlier this week, the first official post-release patch was released for Windows 11, and many were perhaps hoping that it would provide a fix for the performance drop bug found in AMD Ryzen processors. Well, following a report via TechPowerUp, the bad news is that it hasn’t. In fact, it’s actually seemingly making the L3 cache latency problem even worse (almost three times greater than the original gain). – So, the short version is that if you own a Ryzen CPU, it’s still not in your best interests to make either the upgrade to Windows 11 or indeed this latest patch if you’re already on it.

There is, however, some good news as following an official statement, AMD has confirmed the dates on which the two major issues will (hopefully) be resolved!

AMD Ryzen Still Problematic on Windows 11

For those of you unaware, AMD Ryzen currently has two major issues on Windows 11. In brief, the preferred core system isn’t working, and the L3 cache latency is notably high. Combined, this is resulting in around a 3-5% performance drop in general operations, whereas in gaming, this is as high as 10-15%. – Following an official post on their social media channels, however, AMD has confirmed that fixes for both issues are on the way:

• The ‘preferred core’ issue fix will be released on October 21st. Enterprise users may, however, be able to request this sooner. – This is likely to be released as a chipset update directly by AMD on their website.
• The L3 cache latency issue will be fixed directly from a Windows 11 update scheduled for October 19th

Grumbles Grow Over Intel Bias

The whole AMD Ryzen issue is undoubtedly a very embarrassing problem for Microsoft and is certainly not a good way to kick off a brand new operating system. Given that it’s well-known that Windows 11 is being very specifically catered towards the upcoming big.LITTLE core architecture design of Intel Alder Lake-S has already led to many accusations that some kind of underhanded dealings have been going on here between Microsoft and Intel. – There is, of course, no proof of this. Let’s be honest though, Windows 11 had plenty of time to identify this issue with AMD Ryzen and more than enough to fix it! The fact that this wasn’t even seemingly noticed until release is not just annoying for those Ryzen users who have already made the move to Windows 11, but again highlights, at the very least, more poor quality control from Microsoft.
