The power profile modifies Collaborative Processor Performance Control, making adjustments to CPU task scheduling on Windows to deliver snappier performance for AMD Precision Boost, which dynamically adjusts clock speeds. The end result is better performance and core usage while idling or performing heavy load tasks. AMD will likely be investigating these improvements itself too to improve Precision Boost behaviour in the future.
The 1usmus Ryzen power profile is now in version 1.1. As the creator himself explains, this new update adjusts the Windows task scheduler to “must use best cores”, which means low threaded workloads should see better CPU utilisation.
Microsoft just recently began rolling out a new Windows 10 update but the Ryzen Universal power plan v1.1 should benefit all Windows 10 builds with any BIOS. You can get the full details and download over on TechPowerUp.
