Some sources claim that the AMD's Ryzen CPUs is expected to perform better in Windows 10 except for the way the operating system incorrectly handles Ryzen's simultaneous multi-threading (SMT). It's told that instead of leaving it to the smaller tasks, it lumps them right in with the main cores, which can result in a real dip in performance.

According to Digital Trends, Intel has been offering hyper threading as one of their CPU features for a long time that's part of why it has maintained a performance lead over AMD for many years. Ryzen introduced SMT as its alternative multi-threading technology and it works amazingly good, but some research also suggests that Windows 10's Scheduler doesn't seem to realize that those virtual cores aren't as capable as the real ones.

As per MS Power User after four years and more than two million engineering hours of hard work to develop the processor, AMD finally announced the launch of AMD Ryzen 7 desktop processors. AMD designed these processors for PC creators, gamers, and enthusiasts with 8-cores, 16-threads, and the new AM4 desktop platform. According to AMD, their new flagship Ryzen 7 1800X is expected to be the world's highest performing 8-core desktop processor, and Ryzen 7 1700 is the world's lowest power 8-core desktop processor.

The Scheduler also seems to think that Ryzen CPUs consist of as much as 136MB of cache, whereas in reality, they have only 20MB of L2+L3 cache, according to WCCFTech. AMD is said to be aware of this issue.

At present, the issue is only believed to affect Windows 10. Windows has had schedule issues in the past also, so we are sure a solution is only a software update away. In the meantime, users can disable SMT in the BIOS to improve performance and gaming experience, but for more multi-threaded work it may be better to leave it enabled.
