System specs
[System]: Apple iMac (Retina 5K, 27-inch, 2017)
[OS]: Windows 10 (via Bootcamp)
[CPU]: Intel Core i5 3.5 GHz
[GPU]: AMD Radeon Pro 575 4GB
[RAM]: 40GB DDR4
[eGPU]:AORUS GAMING BOX GeForce RTX 2070 8GB GDDR6
eGPU hardware
AORUS GAMING BOX GeForce RTX 2070 8GB GDDR6
Installation steps
Almost plug'n'play with WIN10, had the eGPU disconnected until windows was fully loaded then I connected the USB-C cable and turned on the power. Windows recognised the eGPU as "Microsoft Basic Display Adapter" in device manager. I downloaded the latest drivers from Nvidia and right clicked on the "Microsoft Basic Display Adapter" to be able to install the drivers manually. After a restart with the eGPU unplugged and powered off I reconnected the eGPU, powered it on and it was recognised as Nvidia Geforce RTX 2070.
Since I am only going to be using the eGPU for Octane Render I haven't tested the internal or external monitor, but the eGPU works fine with RTX Octanebench 2019 Preview and Cycles for Blender. See Octanebench results below.

Hello! Thanks for sharing your setup! I am planning to build my own, almost same to yours, but with iMac 4k (RP560). And I have 2 questions:
1. Which windows 10 version did you use, 1809 or 1903?
2. Should I install AMD Driver from bootcampdrivers.com or I can use default one (from apple drivers) ?
Thanks in advance!!! 😉

HI friends,
