Created attachment 139206 --> https://bugs.freedesktop.org/attachment.cgi?id=139206&action=edit amdgpu_pm_info with 4.15 kernel
There is a problem with amdgpu power management. With kernels 4.15.X MCLK is always stays at max value. With kernels 4.16.X MCLK/SCLK both stays at max.
At idle desktop GPU draws about 4W more, according to /sys/kernel/debug/dri/0/amdgpu_pm_info
