The iMac Pro launch is within weeks. I paired the nMP to an RX Vega 56 eGPU to get a baseline performance. My 6,1 is a hex-core 3.5GHz and the dual D500 discrete graphics cards. The drivers in 10.13.1 are far from mature but they are functional. I can plug the eGPU in anytime without crashing the Mac Pro. I've tried booting with a 4K display connected to the eGPU and that worked well. Using Thunderbolt Bus 0 with either Port 5 or 6 is recommended (bottom Thunderbolt 2 ports).

 

System specs:

Late 2013 Mac Pro – Xeon E5-1650 v2/2x Radeon FirePro D500 dGPU/32GB RAM/1TB SSD

 

eGPU hardware:

Mantiz Venus + Radeon RX Vega 56 + Apple TB3 to TB Adapter + 2m Thunderbolt 2 cable

 

Hardware pictures:

 

Installation steps:

By default macOS High Sierra shows the RX Vega eGPU as "RX XXX". I made a small change in the controller file of AMD1000Controller.kext to show "Radeon RX Vega56. I used iHex to find and replace "RX XXX".

 

Benchmarks:

Final Cut Pro X can make use of the eGPU with and without an external monitor connected. I tested both modes and consistently got 13 seconds on average to complete BruceX. The dual D500 dGPUs take 24s for the same test.

I also ran Luxmark and Geekbench to compare the dGPU vs eGPU. OpenGL is broken so I couldn't run Unigine benchmark yet.

I will definitely re-run the benchmarks as well as OpenGL once the final version of 10.13.2 is released. The beta builds have power management issues so far.

Hi! How about the benchmarking 10.13.2 is it faster than 10.13.1? I'm excited to try my Sonnet 550W eGPU with my nMP2013 just waiting for Vega 56 available in stores.

@artik I didn't get a chance to run with 10.13.2 but in 10.13.3, OpenCL performance for eGPU seems better. I ran these benchmarks with Luxmark and Geekbench with build # 17D29a.

 

I recently got the Samsung 49" monitor and it works great at full resolutions 3840 x 1080 @ 120Hz.

@flint-ironstag I'm planning on doing a review of this monitor soon. It works great with the nMP btw, full resolutions running at 120Hz.
