    What kind of performance should I except with RX 550 on Ubuntu 16.04 or 18.04?


      Machine specs:

      Laptop: Lenovo Thinkpad E580

      Memory: 8GB

      SSD: Samsung 960 nvme

      GPU: Intel UHD 620 and AMD RX 550.


      These are the distros I have tried:

      Ubuntu 18.04.1 (Gnome)

      KDE Neon (Ubuntu 16.04)

      Kubuntu 18.04.1


      On all of the distros I have tried the built in amdgpu driver, I have installed the 18.30 amd driver both all-open and pro editions. (Pro gets me a black screen in KDE).

      I get about a bit under half the FPS as I get with the intel card.



      AMD card:

      ari@laptop:~$ DRI_PRIME=1 vblank_mode=0 glxgears

      3708 frames in 5.0 seconds = 741.567 FPS

      3869 frames in 5.0 seconds = 773.752 FPS


      Intel Card:

      user@laptop:~$ DRI_PRIME=0 vblank_mode=0 glxgears

      9599 frames in 5.0 seconds = 1918.674 FPS

      8751 frames in 5.0 seconds = 1750.149 FPS



      What could be wrong?
