Are there benchmarks for various mobile GPUs?

Maybe the developers could put in a benchmark mode into PPSSPP and add a benchmark record option. Maybe. I can tell you from my testing 80+ games:

Settings: 4x Buffered Rendering, FXAA Shader, 2xAF, no Frame skip. All other options on default.

Nvidia Shield TV: 85% of the games I've tested run full speed (higher near full speed)
Nvidia Shield Tablet: 75% of the games run full speed
HTC1 M8: 20% of the games run full speed (mostly 2d RPG games)

In general, Nvidia Tegra devices will trounce all other mobile Android devices simply because they have the best drivers. Adreno GPU's tend to be very powerful hardware wise, but are help back a lot by their drivers. PowerVR devices have some issues with rendering because they are Tile Based for 3d. Mali GPU's are fairly more performant compared to their Adreno counterparts, but are a bit hit and miss on some render functions.
