Ryzen is probably the biggest blockbuster thing to have happened to the tech industry this year. But the early adopters who used the processor with Windows 10 are now facing a few performance related issues. If you are also facing the issue, then rest assured, your particular system isn’t at fault, there are many like you.
Several reports have confirmed the performance of the AMD Ryzen processors is severely crippled on Windows 10. Unfortunately, there isn’t much that you can do at your end to resolve the issue.
Actually, the issue is with the Simultaneous Multi-Threading (SMT) technology that came along with the AMD Ryzen processors. The processors aren’t able to optimise the technology and that’s because of a bug in Windows 10 Scheduler which is unable to differentiate its principal core threads from the virtual SMT threads.
The performance per watt value of the Ryzen series has been excellent consistently but this isn’t the case with the CPU running on Windows 10. Reportedly, Windows 7 seems to be unaffected by this bug, but the performance of the processors on Windows 8.1 is still not known.
In the case of Intel’s hyper-threading, the Windows 10 Scheduler is able to correctly identify the hyper-threads and schedule the tasks accordingly without affecting the performance. Unfortunately, the scheduler currently isn’t able to differentiate principle core threads from the virtual SMT.
Microsoft has already acknowledged the issue and is said to be sending a patch really soon. It may also come along with the Patch Tuesday monthly update on March 14.
Till then, you can’t expect the Ryzen processor to perform well on Windows 10 under heavy workloads. For those who are already using the processor and Windows 10, will have to wait for the patch to arrive. And those who are planning to invest in one, you should wait for a sometime till Microsoft issues a patch.
