I hope, this will make the power consumption lower with forthcoming patches. I have a wall meter here and the idle power consumption of my 3700X is obscenely higher than in Windows. Newest arch kernels, of course. I get ~80 W idle here AT BEST (RX 5700 XT + ROG Strix X570-E Gaming) – normally it’s around 100 W. Whereas under Windows, it goes as low as 65 W. That’s downright embarrassing for a company selling server chips.

This is just embarrassing. And now they can't support agesa code on pre-500 series AM4 MB's. Their software dev really went sideways when they shut down their German software team.
AMD has the hardware and net profit margins now. They need to unfk this 3rd world software dev they have going on. That is now AMD's achilles heel, next to their Chinese production exposure.

-Try powertop and go two-three tabs on the right... then make everything "good" except perhaps the mouse.
-Try echo powersave > /sys/module/pcie_aspm/parameters/policy
-Try echo low > /sys/class/drm/card0/device/power_dpm_force_performance_level

AMD has an extremely poor track record with managing and retaining software talent. Whoever has been in charge of that is holding them back, and that's a big part of why they are losing outright in machine learning, why the best drivers for their hardware are usually written by third parties.
Please, AMD, just spin some cash into a skunkworks, and keep firing whoever's in charge of it until it starts bearing fruit; it's not that hard.

And I’ve had this excess in power consumption between Linux and Windows with a Radeon RX 580 too, it’s not the AMDGPU driver for the RX 5700 XT causing this (tested with light GPU load on Windows too).
But thank you both guys for your help, seriously.
I actually think, it’s AMD not getting their powerstates fully upstreamed.Last edited by holunder; 16 May 2020, 05:39 PM.

I've got Linux on a 1700X running in a x370 board with six HDDS, two SSDs and a M.2 NVMe drive and it idles at 55W, measured by the UPS.
If your Linux is running hotter than Windows is, maybe you've got a driver or such that is reclocking your hardware. Or maybe the Windows drivers are doing something with the PCIe clocks, because I've read that PCIe Gen 4 does run a lot hotter than Gen3. I haven't noticed that on my 3900X system since it's got a Vega 56, so no Gen4.
