I appreciate Intel working on these P-State patches to benefit my aging ivybridge laptop. Hope skeevy420 is only joking about the impact of LVI.

So are we really talking about -33% in gains when LVI is factored in?

Phoronix: Intel P-State Changes Could Improve iGPU-Bound Performance - Some Cases ~15%, ~43% Perf-Per-Watt
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...
