System specs


eGPU hardware

Aorus Gaming Box 1080 (with nVidia GeForce GTX 1080), BIOS F1.3, original 0,5m TB3 cable


Hardware pictures

(note to the picture above: I did dim the laptop screen on purpose; it can be quite bright)

(note to the picture above: Aorus Gaming Box 1080 is standing with the front facing the wall - this makes accessing the ports much more convenient)

(note to the picture above: from top to bottom: active USB3.0 hub, USB sound card, volume control)

(note to the picture above: yes - I have 2 USB-C-like cables, one TB3-cable for the eGPU, one from the DisplayPort of my screen to the USB-C-/TB3-port of my laptop)

 (note to the picture above: HWInfo64 information on the TB3 port)

Installation steps


  • Performed all BIOS- and driver-updates through DELL Update
  • Installed Intel Driver & Support Assistant
  • Uninstalled DELL Intel UHD Graphics driver
  • Updated all drivers using Intel Driver & Support Assistant,
    installing the Intel UHD Graphics driver in place of the (older) DELL one
  • Installed all USB-devices into the active USB3.0 hub (not the Aorus Gaming Box - it feels to me like it made some difference)
  • Optional (may help with stuttering issues): deactivate C3-states and/or Intel SpeedStep in BIOS (reduces power safety features) - this turned out to not be necessary after the latest driver updates and using the active USB3.0 hub
  • Optional (may help with stuttering issues): DELL USB-C Patch.

I have not tried using any other OS on this laptop, but I will enhance this section if I do.


CUDA-Z (Aorus Gaming Box 1080, external 4k monitor):


1920x1080 High Quality, 8xAA (Aorus Gaming Box 1080, external 4k monitor)

3840x2160 Ultra Quality, no AA (Aorus Gaming Box 1080, external 4k monitor)

1920x1080 Ultra Quality, 8xAA (Aorus Gaming Box 1080, internal display)

1920x1080 High Quality, 8xAA (Aorus Gaming Box 1080, internal display)

  • As you can see you are better off gaming in 1920x1080 via external display
  • High Quality -> Ultra Quality (both in 1920x1080 with 8xAA) = -4fps on average
  • Disabling AA on High Quality settings in 1920x1080 (internal display) makes the average FPS jump to ~100fps
  • Internal iGPU runs 1920x1080 on low settings (internal display) at about 20-30fps
  • 3840x2160 on High Quality (external display) w/o AA can be playable - depending on the game

Since I am only really playing RocketLeague, I cannot really test with anything else unless you offer me a Steam Key (if there is one; I do not want to install UPlay, Origin or Epic).


Pros / recommendation:

  • Use the Gaming Box (GTX1080) for games only
    • Less noise
    • Less stuttering (though mine almost went away with latest driver- and BIOS-updates)
    • Prefer [email protected]/Ultra Quality with some AA
    • [email protected] Quality w/o AA may also work
  • Use iGPU for office / browsing
    • Usually sufficient performance for regular applications (e.g. development, Word, etc)
    • Much quieter
    • Can drive a display via HDMI or USB-C (I am using DisplayPort-to-USB-C-cable and it works with my monitor)
    • Really bad for games
  • Use active USB3.0 hub for your devices (usually seems to work better)
  • Refer to this thread where I noted a few solutions to the problems I had a bit more in-depth and feel free to ask questions

Nowadays I use this set up as my main driver for everything: graphics design, development, audio- and video-editing and gaming and I am loving it, because it is always mobile!


A Desktop is much quieter while performing somewhat better.
