iMac Pro (Base) + Gigabyte AORUS 2080TI + Razer Core X + Windows 10 2004 - Sucess [on internal display - not worth it]
What do I have:
- iMac Pro Base (8-core Xeon + 32GB RAM + Vega 56)
- BootCamp Windows 10 2004
- AMD Drivers from bootcampdrivers.com
- Razer Core X
- Gigabyte AORUS 2080Ti Xtreme
- Samsung 4K 65" NU8000 TV as an external display
Just plug&play downloaded Nvidia drivers from the official website and that's it. Works great, boots with connected eGPU also plug&play works as well. Once get error 12, but after the restart, it has gone. So it may have some issues and instability but after the restart, everything works flawlessly.
Short answer: not worth it if you plan to use it with an internal display. But for external display difference is noticeable, so with eGPU, you definitely need to get a second monitor.
Long answer: some numbers from 3D Mark:
TimeSpy (only Graphics score):
- 2080TI - 6392
- 2080TI (external) - 12856
- Vega56 - 5653
Firestrike (Graphics / Physics / Combined):
- Vega56 - 18232 / 18619 / 5618
- 2080TI - 12561 / 13654 / 6499
- 2080TI (external) - 25512 / 17739 / 7148
Firestrike Ultra (Graphics / Physics / Combined):
- Vega56 - 4437 / 18643 / 2050
- 2080TI - 5985 / 13835 / 3726
- 2080TI (external) - 7783 / 18652 / 4534
As you see if you're using internal display, it is better to stay with standard Vega56.
But if you're getting a second display - it is definitely starting to shine.
Hope these results will help somebody.
