System specs

  • 2018 15" MacBook Pro (Radeon 560X, Intel UHD Graphics 630 1536MB)
  • Intel i9, 32GB RAM, 1TB SSD
  • macOS Mojave 10.14
  • Dual LG 27" 4K 60hz DisplayPort monitors

Installation steps OSX

Nothing! worked out of the box, plugged in and viola!

Installation steps Bootcamp Windows 10 Pro

Now this is where it gets tricky, but I did manage to get it work with the 2018 Plug and Play, although it took some time to figure out the installation steps. 

  • Install Bootcamp using Bootcamp Assistant normally with the eGPU disconnected.
  • Boot into Bootcamp and install Bootcamp drivers.
  • Restart.
  • Hot plug the enclosure into the left side TB3 port (either will do).
  • Wait for windows to detect and install the card. Opening device manager should list Radeon 560X with a yellow punctuation mark and opening it should display "Windows is uninstalling the driver for this device" or something of the sorts, and there should be an additional listing for RX Vega which should display "This device is working properly". This may take some time to detect and install. 
  • Once that's done, you restart again, this time with the box plugged in. DO NOT connect any other USBC cable or the machine won't boot (no idea why).
  • At this point, you'll be logged into Windows with the cable plugged in and the displays up and running through the eGPU. Woohoo! you can now plug in any other USBC cable (wait for Windows to load first). The next boots should not require this step.
  • You'll notice the internal display is dark with no image, I've yet to solve this but I don't use it anyway when it's plugged in so I don't mind. 
  • You can now download the latest driver from AMD, unpack it and manually install it using device manager -> update driver on the RX Vega entry. Be sure to select the RX Vega driver inf file from the unpacked driver installer as AMD's tool will not recognise the card automatically for some reason. 
  • That's it!

To be completely honest, this setup is a dream and once you get through the boot sequence install step it's amazing how plug and play it is. It works like a charm and I can play my graphics intensive games easily even at 4K for some optimised titles.
So far Call of Duty Black Ops 4 runs perfectly in 2160p at max settings and at 4K at lower settings. 
I've never actually believed this could be pulled off, so it's incredible how eGPUs work so well in 2018. It's also great under macOS both as a one cable for charging and dual monitor setup and both for macOS gaming (yes, that's right!). 

The best part is both OSs have the i9 at around 70 degrees celsius, which is incredible compared to when the internal GPU is active (90-100!!!), so no more overheating. 

Now to play some FPS games!

Hi,

Thank you so much for posting this review and setup, it helps noobs like myself to pull the trigger. I am looking to purchase this exact same eGPU setup (Sonnet 650 and Vega 64) to go with my new 2018 Mac Mini. How loud does this setup get? I was also looking into getting this card from newegg:

SAPPHIRE Radeon RX Vega 64 DirectX 12 21275-03-20G 8GB 2048-Bit HBM2 PCI Express 3.0 CrossFireX Support Video Card

Is this the one you got? The only thing holding me back is, this card linked above is a 21275-03, but Sonnet's compatibility chart does not list it, they list a 21275-02.

Thanks

Where do you find the unpacked AMD drivers?

Hi Daniel,

I have this exact setup.  The card works very well and is quiet too until it ramps up under load. 

Note that I think that I have a newer version of this Sonnet eGPU with a different PSU that has a larger, quieter fan.

I just found that the card seems to run well and not loudly left at stock settings in my new exclosure ( Sonnet Breakaway Box 650W. Sapphire Vega 64 - (21275-03-20G card). 

The model in my new Breakaway Box 650 is a High Power HP1-J650GD-F12S - 650W, I cannot find the model on their website. Purchased February 2019.
It has a PSU switch and is fairly quiet in comparison to the Enermax ERV650SWT SFX 80 because it has a much larger fan.  It also is larger and looks like an ATX PSU, not SFX.

From Sonnet FAQ:  Sonnet uses the Enermax ERV650SWT SFX 80 Plus Gold in the Breakaway Box 650. Sonnet uses the higher-performance Akasa AK-FN059 fan in Breakaway Box 650.

Best wishes.
