Home » Microsoft acknowledges AMD Ryzen performance issues on Windows 10, fix incoming

If you’re planning to buy an AMD Ryzen computer and run Windows 10 on it, think again. Recent reports confirm that AMD Ryzen’s performance is severely crippled on Windows 10, and there’s not much that you can do about it.

Ryzen is AMD’s first processor model to sport simultaneous multi-threading technology. According to AMD, Ryzen is 40% more efficient, consuming less power than its Intel counterpart. However, it seems that Windows 10 doesn’t really like it.

AMD Ryzen low performance on Windows 10

The Windows 10 scheduler is not able to correctly identify Ryzen’s principal core threads from virtual SMT threads. Actually, the OS believes that each CPU thread of a Ryzen processor is a real core with its own L2 and L3 cache.

As a result, Windows 10 doesn’t assign the tasks to a principal core thread. Instead, it schedules many of them to a virtual SMT thread, which of course, reduces the overall CPU performance.

There are many users who aren’t ready to give up on their AMD Ryzen-powered computer and hope that Microsoft and AMD will somehow fix this problem.

I just want MS/AMD to address the bug. I am not worried about how much it affects the improvement in games. We ought to  be able to use the software and hardware we bought with hard-earned money properly in all fields, not just games. AMD/Microsoft please fix this asap

Microsoft has officially acknowledged this issue and confirmed is working on a fix. This means that the company will soon roll out a patch to address this compatibility issue. At the moment, Ryzen is not unusable, it’s just that it’s not as good as it could be. Let us hope that Microsoft sorts out the scheduler and cache issues as soon as possible. Maybe the upcoming Patch Tuesday update scheduled for March 14 will bring this coveted patch.

However, this doesn’t offer AMD a good excuse. The company should have conducted more in-depth tests on Windows 10 to discover and fix potential issues before launch day and avoid being taken completely by surprise by these issues.
