Installation

The installation process is usually straightforward if you use one of the solutions on this forum.

For macOS

Native compatibility: This eGPU setup has official support and does not require any additional software-work to get working. It is also easy to connect multiple such eGPUs.

Not all applications take advantage of external GPUs. For that, one can use set-eGPU.sh for High Sierra (10.13.4+) or use the Prefer External GPU option in Mojave.

 

For Windows 10

Drawback: Unable to use internal display, but performance gains worth it on external monitor(s).

The setup process is simple:

  • Download a copy of AMD drivers from bootcampdrivers.com.
  • Disconnect all internet connectivity and devices from Windows.
  • Use DDU to uninstall Apple-provided drivers. It is recommended to do so in Windows Safe Mode.
  • Boot back into Windows and install the downloaded drivers.
  • Once the Radeon Pro 560X is up and running, reboot into Windows with eGPU plugged in or hot-plug.
  • Ideally, the eGPU should begin functioning. If not, connect to the internet and let Windows set up the device.
  • You will lose your internal display, so only plug in an eGPU which has a monitor connected.

 

Benchmarks

Some interesting benchmarks on macOS:

Valley, Radeon Pro 560X

Valley, RX 480

LuxMark, Radeon Pro 560X

LuxMark, RX 480

 

Comments

I only use the eGPU for testing purposes at this time, but my experience and benchmarks make the following clear:

  • Compute performance over 560X: ~2.4x.
  • Valley really does not do well on AMD cards, and both cards perform better on the bench in Windows.

 

Windows benchmarks will be added soon.
