2018 15" MacBook Pro (RP560X) [8th,6C,H] + RX 5700 XT @ 32Gbps-TB3 (ASUS XG Station Pro) + Win10 & macOS 10.15.4 [OliverB] // Navi vs Radeon VII vs GTX 1080 Ti
-MacBook Pro 15 inch 2018, i7-8850 6-core, 32GB Ram, 1TB SSD
-External FreeSync Monitor Samsung 2560x1440
-Windows 10 Build 1809 Bootcamp
a) MacOSX Catalina 10.15.4:
b) Windows 10 Build 1809
0. Start with a clean Windows 10 Build 1809 with Bootcamp Drivers.
1. Download newest AMD Adrenlnie Drivers 20.3.1 or newer. Expand it.
2. Disable "Radeon Pro 560X" in Device Manager. (to avoid black internal screen):
3. Hotplug AMD eGPU.
4. Right click on "VGA Device" in Device Manager, "Update Driver", "Browse my..." and select where you expanded 1.
5. Some time later you will get an expected Error 12.
For the sake of simplicity we use Build 1809 and dispense an internal accelerated display. It's possible to run both cards, but need more steps:
There are not many MacOSX Benchmarks, as Catalina scrapped almost every game and a lot of applications. So we focus on the Windows Benchmarks, which are coming soon...
Here are the benchmarks of 20 games, 1440p Ultra Basic AA, similar to This comparison between Radeon VII and GTX 1080 Ti. As I don't have anymore a Radeon VII, I cannot add new games. While benchmarking I met a couple of difficulties with 5-6 games, e.g. game crashes or no overlay displaying (for FPS).
This is actually an issue of the RX 5700 XT and its driver, because the games work fine under any other card, including the dGPU Radeon Pro 560X. As a result I had to remove those games. The final results:

@itsage, you are correct: It is really very quiet. You don't hear anything, neither from the Asus Station, nor from the Navi card. Later I will test the noise in dbA.
- Very quiet and cool
- Plug'n'Play in MacOS 10.15.4 Catalina, works flawlessly
- The LEDs are surprisingly good looking
- Ok performance, comparable to a well clocked GTX 1080
- You have to upgrade to Catalina and will probably lose quite a number of Apps and Games, especially those who use eGPU.
- There are some issues in a couple of games, probably driver related
- The well known AMD issues in Windows, especially Error 12.
Ethernet with a USB-C Hub connected to Asus XG Station Pro didn't work in Catalina. It's still unclear, if this is a issue with the OS or with the cad. No issue, it was a missing driver problem.
I have some numbers concerning noise (in dBA) 15cm in front of the eGPU:
This is good. Actually the Max 55 is only for a short time for very aggressive benchmarks and immediatetely is cools down.
But (now comes the but), I rechecked my old EVGA SC2 1080 Ti and the result for the exact tests are:
With my setup if I have to decide between RX 5700 XT and GTX 1080 Ti, the nVidia card still wins (what a pity). There were some unexpected drawbacks for the Navi card as:
- Catalina disables almost all of your games and many your apps
- Some minor driver issues on particular games
- Still nVidia goes so much better with Bootcamp/Windows. Hotplugging possbile, there is no Error 12, there is no "Do not upgrade 1093.395".
@oliverb, The GTX 1080 Ti is definitely still very competent compared to the newest GPUs. That noise level is excellent at max load. Regarding Ethernet through the hub, do you know which Ethernet controller it has? If macOS has no native drivers, it wouldn't work plug-and-play. You may have to find third-party drivers for it.
