Bug ID: 207483 Summary: PowerColor AMD RX580 much higher power usage on idle than Windows 10 Product: Drivers Version: 2.5 Kernel Version: 5.5.2-050502-generic Hardware: Intel OS: Linux Tree: Mainline Status: NEW Severity: low Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: andrea.somaini00@gmail.com Regression: No

I have this GPU installed on my system: https://www.powercolor.com/product?id=1493084304

The problem is that the power usage while using Linux and just looking at the desktop is much higher than on Windows, in particular:

~7,2 Watt Windows 10 ~31,2 Watt Linux (Xorg, Wayland, tty only etc)

It is more than 4 times as much power!

Indeed, after a while doing light web browsing, the temperatures are different in the 2 systems with the GPU fans turned off, in particular:

~37.0°C on Windows 10 Between 43.0°C and 50.0°C on Linux
