My technical knowledge in what regards to eGPUs is quite poor, I'm posting my experience as a way to say thanks for all the help this community gave me.

System Specs

Macbook Pro 2019 13", Intel Core i5-8279U, SSD 256GB, 8GB RAM

Screen Shot 2019 07 18 at 16.20.51

Tested on:

  • macOS Mojave 10.14.5 (18F132)
  • Windows 10 1903 Home (Bootcamp)


eGPU Hardware
Enclosure: HP Omen Accelerator
Video Card: Sapphire Radeon RX Vega 56

Screen Shot 2019 07 18 at 16.25.10

I replaced my RX 580 by a Vega 56 and followed the advice from this forum in order to make the video card work with the enclosure.
The thing is the Vega 56 requires 2x8 pin connectors and the Omen Accelerator has only 2x6 + 1x2 pins so I bought a 6pin to 8pin adapter in order to get those 2 extra pins. There's a bit of controversy about this setup here:  https://egpu.io/forums/mac-setup/high-sierra-unable-to-detect-rx-vega-56-with-hp-omen-accelerator/

Installation steps

  • macOS: Just plugged in the cable and it worked
  • Windows 10: Installed Windows 10 via Bootcamp on the macbook internal ssd, booted on Windows and then plugged in the eGPU.

Issues found:

  1. The enclosure doesn't charge the macbook, you will see on System information -> Power something like "Connected: Yes, Charging: No"
  2. I cannot boot on Windows with the eGPU connected probably because of that problem with the iGPU, tried adding the uEFI partition but doesn't seem to work on this macbook model.
  3. For both systems, macOS and Windows, I have to plug/unplug several times the eGPU until it is properly detected. I haven't had that issue with my previous MBP 13" 2017 no-touchbar

Regarding to gaming, I only tested Fortnite, it runs at 60-110fps 1080p epic settings, much better than my previous RX 580 which was able to reach 50-65fps in average with the same settings.

UPDATE:
After testing this build for 1 or 2 weeks I can say despite I have to start Windows with the eGPU disconnected and maybe plug-unplug the enclosure 1 or 2 times in order to make Windows to detect the hardware (probably a software issue), overall it works nice, also undervolted the Vega 56 with WattMan and got around 50-60fps epic/4k on Fortnite without recording the screen with that terrible Windows tool:

Thats crazy simple set up wise, both macOS and W10... 
Looks like your CPU was not bottlenecking your 580.
Do you play PUBG at all? Would be super interested in your FPS if so...

@eightarmedpet the setup was simple, but unstable at the same time, I don't know how to fix the #3 issue, so I have to plug and unplug the egpu multiple times before being able to use it, that's the only reason why I wouldn't recommend this setup, at least for now.
About the cpu bottleneck, my analysis could be wrong so don't take it as a source of truth, but...I was worried about that with my MBP 2017 + RX 580 and run some tests with the Afterburner while playing Fortnite.
In my tests, the GPU usage was always 100% while the CPU was between 60-90% depending on the graphics configuration.
If you set epic settings, your GPU will work harder and less work for the CPU, and viceversa....so seems to be more probable to have a bottleneck if you set graphics to low and want to run the game at 300fps....at 144fps it worked fine.
Even comparing my results with a youtube benchmark (same gpu + ryzen 2600x) the results were almost the same. I don't play PUBG but based on some youtube benchmarks I saw, the performance should be similar to any desktop-cpu machine with the same GPU.
So, to sum up, in CPU Benchmark that 2-core processor has 5865 points, in the other hand the i5-8279U is not in the list, but the i5-8259U from the 2018 model has 11013 points (because of the 2 extra cores)... so I'd say you will be ok with any 2019 macbook pro 13" processor.

Please feel free to correct me if I am wrong with anything.

Glad to read that it works well finally. We have at home an Hp Omen Accelerator that they gave us, unfortunately we don't have any equipment to use it since I have a macbook pro from 2012. I will buy another egpu since it did not work with an adapter. We hope to use it in the future.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.
