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-...@kernel-bugs.osdl.org
Reporter: andrea.somain...@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
