No that's the issue, i don't have hw anymore but according to bug it is AMD FirePro
M5170 and M6170 which would make them amdgpu afaict but i remember the hw was using
radeon so i am not sure how to figure out what GPU it was really.
Bug https://bugzilla.redhat.com/show_bug.cgi?id=1269009
Cheers,
Jérôme
