Bug ID: 214071
Summary: amdgpu idle power draw to high at +75Hz
Product: Drivers
Version: 2.5
Kernel Version: 5.13.10
Hardware: x86-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - non Intel)
Assignee: drivers_video-...@kernel-bugs.osdl.org
Reporter: p...@gmx.de
Regression: No
For best viewing pleasure I usually set my monitor to 144Hz and native 1080p.
At that refresh rate my RX6900XT draws about 35 Watts in idle situations
Memory clock stays at 1000Hz.
I have to lower the monitors refresh rate to 75Hz, then the card draws only 8
Watts in idle and memory clock goes significantly down to 96MHz.
Using 100 or 120 Hz does not help.
Situation in windows is different. The same hardware setup works in Windows10
at 1080p@144 with idle power draw of just 8 Watts.
So my guess is this is a driver issue and not a hardware issue.
