Intel P-State changes could improve iGPU-bound performance

Stefan Mileschin · 13th March 2020, 13:26

We’ve known that Intel’s P-State Linux CPU frequency scaling driver in general can be a bit quirky and especially so when dealing with Intel integrated graphics where the iGPU and CPU share the same power envelope. This has been shown with examples like using the “powersave” governor to boost iGPU performance while discrete graphics owners are generally best off switching over to the “performance” governor. As the latest though on helping the iGPU front with P-State, there is a new patch series talking up big gains in performance and power efficiency.

Francisco Jerez of Intel’s open-source driver team sent out a set of ten patches today working on GPU-bound efficiency improvements for the Intel P-State driver.
