There are some issues when loading amdgpu driver with dpm=3D0.
It leads to using Intel as OpenGL renderer (glxinfo) instead of AMD.
Error Message: Xorg.0.log:[ 24.261] (II) UnloadModule: "amdgpu"
I got two patches from AMD to fix the issue.
After applying patches, tearing issue is back.

Here are some new findings:
The issue can be reproudced on 5916&5917.
But, I only see the issue on 5916 when running glxgears with fullscreen.
When unplugging power adapter and running glxgear with default window size,=
 the
issue on 5917 is gone.

Test Environment:
Device 1 (5916):
