dmesg
AMDGPU on SI devices appears to be much slower then radeon currently is.
For example, Unigine Heaven 4.0:
AMDGPU FPS:18.3 Score:460 Min FPS:9.5 Max FPS:46.1
RADEON FPS:38.4 Score:967 Min FPS:7.5 Max FPS:83.5
Reading /sys/kernel/debug/dri/0/radeon_pm_info both report the same values:
uvd vclk: 0 dclk: 0
power level 3 sclk: 105000 mclk: 140000 vddc: 1206 vddci: 1025 pcie gen:
