Η AMD warned her last week that its processors have performance problems in Windows 11 and now, with its first update Microsoft in its new operating system made the problems worse.
Το TechPowerUp states that he sees much higher latency, which means worse performance after the start of the update Windows 11 yesterday. THE AMD and Microsoft found two problems with Windows 11 to processors Ryze. The Windows 11 can increase the latency of cache L3, slowing down performance by up to 15% in some games.
The second issue affects its technology "preferred core”Of AMD, which shifts the threads to the fastest core of a processor. THE AMD says that this second error could affect performance in tasks with heavy CPU usage.
The TechPowerUp measured the cache delay L3 on the Ryzen 7 2700X in about 10ns and Windows 11 they increased it to 17ns. "This became much worse with the "Patch Tuesday" update of October 12, where latency increased to 31,9 ns", in accordance with TechPowerUp. This is a huge leap in latency and is exactly the problem that the AMD.
For his two issues Ryze corrections will be issued before the end of the month. The issue of cache L3 will probably be addressed next week by Microsoft, with rumors converging on October 19. The main update will be with a processor driver AMD, which is expected to be delivered later this month and we hope will be available at Windows Update just released.
