After scrubbing through the forums and playing with the thought of going eGPU for about 2 years now I finally did it as a Christmas present for myself. Already had the MacBook and wanted to utilize it more as well as having a docking solution for my work notebook in case I do home office. Of course the whole thing should work off of one cable to easily switch devices. 

The setup replaces my "old" tower (i7-3990K, 16GB RAM, GTX 1080) which served me really well over the years and is far from obsolete. I also have a G-Sync display which I can't really use anymore with the AMD card so it was a hard decision if I want to do it. 

System Specs

  • 2018 15" MacBook Pro (i7-8750H, 16GB RAM, RP555X)
  • Catalina 10.15.2, Windows 1903
  • 34" (3440x1440) Asus ROG PG348Q

Installation Steps

macOS

As of macOS Catalina 10.15.1 the AMD Radeon RX 5700 XT is natively supported so this was plug and play

Windows

  • Installed 1903, Build 18362.30 via BootCamp
  • Disabled Windows Update over local GPOs
  • Uninstalled AMD Drivers with DDU and disabled automatic driver installation over Windows Update
  • Shut down the system
  • Plugged in the eGPU
  • Installed latest Adrenalin 2020 drivers from bootcampdrivers
  • Restarted during driver installation and after the install finished

Rather than just following a guide as I should have I tried to get it to run under Windows 1909. Ultimately, after a couple of failed tries I gave up and did the above steps to get it running. Really hoping for native support under bootcamp. Recommend doing a backup when you have got everything up and running just in case.

The eGPU was plug and play with my work laptop (Dell Latitude 7490) under Windows 1909.


Benchmarks

Superposition Benchmark v1.1 15840 1577540048

I run my setup only in clamshell mode so the benchmark is with an external display. Didn't do any more benchmarks but Jedi Fallen Order ran flawlessly as well as Monster Hunter World. Will update this section in the future if I've got some time to do thorough testing.


Comments

  • Reinstalled Windows multiple times but got it running first try after using the right build of Windows (18362.30)
  • The system runs decently quiet under load and although the eGPU sits behind my display the noise is quieter than my old tower.
  • Performance in the games I play is more than pleasing. I had some frame drops when changing areas in  Jedi Fallen Order for example but this could also come from the fact that they are installed on the external SSD which I plugged in on the same side of the notebook, didn't test it with the other side yet.
  • As I also work from home sometimes I needed it to work as a dock for my work laptop as well which it does nicely.
  • Attached to the eGPU is also my mouse, a webcam and mic as well as my USB DAC for my headphones. Didn't have any problems with the devices as of now. I do not use the ethernet port on the enclosure as I heard there are connection drops and driver problems so I just use Wi-Fi.
  • I could declutter my desk and can finally go full notebook life and do not have to manage data between multiple devices anymore.
  • Had some buyers remorse while setting it up but now that it is up and running I'm fully pleased with the solution.

Thanks a lot, although the desk isn't always that clean I need to have it this minimalistic as I get easily distracted otherwise if I ever work from home so I'm kinda forced to tidy up from time to time 🙂

Hi @eltocino you didn't need to use any USB key or anything to force GPU's to stay active because it is a 15 inch, it was literally just the steps you showed above?

Hey @acantril . Well I firstly tried to get it running with the latest version but that didn’t work. After that I installed 1903 between build 30-295. Just uninstalled drivers with DDU and installed the latest bootcampdrivers. After that just start up the system with the eGPU plugged in and everything should run. There are more elaborate tutorials on the forum for more detailed steps if you need more information.

From my constant reading on this forum I believe those are all the steps you need to follow for this set up so long as you have no need for the iGPU to be enabled as it gets disabled by apple firmware when you boot into windows with another GPU connected. I'm wondering if @eltocino ever opens the MacBook because I'd guess the internal screen won't function due to onboard GPU's being disabled.

I really need a new desk.

Well I never really tried or testet it but uhm.. the display works as well. In the device manager both AMD gpu's are recognized (RP 555X and RX 5700XT). Here a picture as evidence under Windows 🙂

Well I guessed wrong... thought there were issues with internal screens on those models, damn its hard to keep up with implementations.

Well I didn't expect it to run either but never questioned it as it wasn't really needed for my use case. Just tried out hot plugging.. but well you could have guessed that doesn't work. Really hoping for native support some times in the future. A massive update for the bootcamp drivers just came out with improved gpu drivers, maybe we get a present from Apple at the start of new year but I doubt it.

Yes, initially the dGPU models had this issue but I believe either a combination or individually (I don’t exactly know which one), bootcampdrivers or Windows updates resolved the problem.

Followed this guide to the letter - but on my 2019 16-inch MacBook pro

error 12.

It frustrates me no end that we still have no definitive fix for error 12 …

Hey @acantril sorry to hear that you still get Error 12. I don’t know about the 16“ MBP, but I think the correct procedure varies a bit from the 15“ as the dGPU still isn’t supported with bootcampdrivers. Please also make sure, that you have the correct version of Windows installed. There should be other builds with 16“ MBPs available, maybe you can find another build guide which works out for you. I‘ll be happy to help as well of course.

The bootcamp drivers work fine with the dGPU as of a few weeks ago. And i'm using .295 which should work. 

There are a fair few people who it just isn't working for … same GPU, but using the 16 inch.

I'm seriously not understanding how others have it just working, without any trouble - it makes no sense.

@acantril Thats true, I guess I must have been lucky. There is another possible fix which might work in your case. I‘ve stumbled across this post. Maybe something for you. Please note that I‘m using .30 in my particular setup.

Do you guys think they will ever natively support egpu under bootcamp?

Is it up to apple or windows?

I am a noob and a I struggling to setup my egpu on boot camp when I m writing this post.......

I am thinking if I should return it and wait until it is natively supported.

@eltocino I went to the Adrenalin 2020 link that you posted, then I went to the "downloads" drop down>"Windows 10">"2020 drivers" and then there are two options Red gaming or Blue enterprise.

Which one should I download?

Hey @stanley_yung

You need to install the red drivers (gaming). I hope it will work out for you as easily as it did for me.
