Hi! I'm mainly referring to this thread in Archlinux forum: https://bbs.archlinux.org/viewtopic.php?id=247667 I have a Sapphire Pulse RX 5700 XT and with the help of the thread above I managed to get it working. The card is not using the AMD reference implementation so it's one of the newer vendor custom design cards. I currently have installed this software stack: - local/linux-amd-staging-drm-next-git 5.4.857545.b4d857ded1c5-1 (which is basically this one https://cgit.freedesktop.org/~agd5f/linux/tag/?h=drm-next-5.4-2019-08-23 as I modified PKGBUILD accordingly) - aur/llvm-minimal-git 10.0.0_r324774.c310e5a7ab6-1 - aur/mesa-git 19.2.0_devel.114565.b2839193987-1 - firmware 2019-08-21 from https://people.freedesktop.org/~agd5f/r … de/navi10/ - core/amd-ucode 20190815.07b925b-1 Everything regarding power consumption is perfect as long as I stay in console. I've also Kernel Mode Setting (KMS) enabled. Executing "sensors" command I get this output ATM (it varies a little bit of course but basically stays around this values): """ Adapter: PCI adapter vddgfx: +0.72 V fan1: 168 RPM (min = 0 RPM, max = 4950 RPM) edge: +42.0°C (crit = +118.0°C, hyst = +0.0°C) (emerg = +80000.0°C) junction: +43.0°C (crit = +80000.0°C, hyst = +0.0°C) (emerg = +80000.0°C) mem: +50.0°C (crit = +80000.0°C, hyst = +0.0°C) (emerg = +80000.0°C) power1: 8.00 W (cap = 180.00 W) """ So according to this output the card uses 8 W in idle mode which is what I'm expecting (also no card fans are spinning which is great). Now if I start KDE Plasma 5 with OpenGL 3.1 backend this changes: """ amdgpu-pci-0c00 Adapter: PCI adapter vddgfx: +0.72 V fan1: 530 RPM (min = 0 RPM, max = 3200 RPM) edge: +51.0°C (crit = +118.0°C, hyst = -273.1°C) (emerg = +99.0°C) junction: +53.0°C (crit = +99.0°C, hyst = -273.1°C) (emerg = +99.0°C) mem: +62.0°C (crit = +99.0°C, hyst = -273.1°C) (emerg = +99.0°C) power1: 32.00 W (cap = 180.00 W) asus-isa-0000 Adapter: ISA adapter cpu_fan: 0 RPM """ Now I have a power consumption around 32 W just by launching KDE Plasma. I didn't start anything else. Having a look at my power meter it's even more then 32 W which "sensors" is reporting (more like 40 W). Another user in the thread mentioned above reported that for him the power consumption stays at 8 W even when KDE is running. There is only one difference: He has a card with the AMD reference design and I've a custom design card from Sapphire. So I can only suspect that there is some difference in the power play implementation. My card also has two different BIOSes and I tried both but there is no difference regarding power consumption. The monitor is connected via DisplayPort if this is of any interest. And here is my "dmesg" output (grepped for "amdgpu"): [ 1.266205] [drm] amdgpu kernel modesetting enabled.
