In a blog post that is sure to stun many users expecting a "thread scheduler patch" in modern Windows versions for AMD Zen-based CPUs, AMD has apparently investigated the reports of thread scheduling issues and found that "the Windows 10 thread scheduler is operating properly for "Zen," and we do not presently believe there is an issue with the scheduler adversely utilizing the logical and physical configurations of the architecture."
So, if you were expecting a Windows 10 or maybe even 7 patch to address some performance concerns, don't hold your breath. The company notes that they tested both Windows 10 and Windows 7 and they "do not believe there is an issue with scheduling differences between the two versions of Windows." In other words, 7 is already ok as far as scheduling, no patch required.The company does still recommend users utilize the "High Performance" plan in their Windows setup for best performance, claiming the software management of CPU speed interferes with Ryzen's native management. There may be an update forthcoming for the Windows "Balanced" plan to fix how it operates with Ryzen, but there will not be a scheduler update planned as of now.
