2017 13" MacBook Pro [7th,2C,U] + RX Vega 56 @ 32Gbps-TB3 (Mantiz Venus) + macOS 10.15 & Win10 [manzanita]
MacBook Pro mid 2017 13”, Intel Core i7 3.5 Ghz Kaby Lake, Intel Iris Plus Graphics 650, 16 GB RAM, 256 SSD, macOS Catalina + Win10
I follow all the steps in the installation guide provided here. I use the latest version of Win Pro, I use reFind in order to select the OS to boot, I connect the eGPU in the lower left TB3 port. Did not encounter any errors (error12, large memory etc). Pretty straight forward. Currently running with the latest AMD Adrenalin drivers. Also I installed OverdriveN tool and GPU-Z in order to overclock the graphics card and monitor the frequency, power draw of the GPU in stress tests.
I use two external 28" UE590UHD 4K Samsung Monitors with FreeSync hooked up via Displayport. i did all kind of benchmark and stress tests (3dmark TimeSpy Extreme, FireStrike Ultra, Unigine Superposition) The only issue with the card I got is that the memory modules are from Hynix, so you can't get the memory frequency beyond 900 mhz. Then, a decent P8 value is 1772 freq, with 1,2V. Those values get a power draw of 290 watts from the eGPU
I’m not primarily a gamer so my interest is to reduce render times in productivity apps. I installed BootCamp because I want to try finding the sweet spot in overclocking the Vega 56 without so much power consumption. Currently I made an image of the BootCamp partition because I have insufficient space. Also, other than the easy ways to overclock/undervolt Vegas Card in Windows, I really hate all the updates and workarounds of Windows. I find myself spending time in useless security updates and such. I'm trying to find a way to be able to modify my Vega card parameters in macOS running in native mode.
Great build... those Nitro cars are by far the best Vega cards IMO.
Navi eGPU support has been a bit underwhelming so far (poor performance, especially in loopback).

@eightarmedpet, although I'm super happy with the Nitro performance, I have to say that I was surprised with the PowerColor RedDevil Vega 56 8GB HBM2. I bought it used, and it shocked me so far. It has Samsung memory, so I could bring its frequency up to 975 mhz. It's a massive card though. Power hungry I've installed it in a Razer Core eGPU enclosure. I even tried it with Cryengine Neon Noir (a benchmark to test raytracing, reflections) theoretically unsupported by Vegas, and it worked great at 1080p full.
Plus I can use one of the three bios in order to flash Vega 64 bios. But I don't have time yet for experimenting with that.
