2018 AMD X399 Threadripper 1950X [R1K,16C,X] + Radeon VII @ 32Gbps-TB3 (Mantiz Venus) + Win10 1809 [itsage] // Radeon VII vs RTX 2080 Ti performance
I had planned to redo dGPU vs. eGPU using newer and more powerful graphics cards. Last time I did it was nearly two years ago using GTX 980 Ti and RX 580. Intel certified Thunderbolt 3 platform such as my X99 build was actually not reliable at all for TB3 eGPU usage. After two different X99 motherboards and different BIOS versions, I have not been able to get Thunderbolt 3 running consistently. Fortunately the GC-Titan-Ridge AIC allows Thunderbolt 3 connectivity on many platforms (unofficially). Therefore I'm using my AMD X399 build for this test. You can read more details on my Thunderbolt 3 + Ryzen Threadripper build.
There's no Thunderbolt header on the ASRock X399M motherboard so I shorted pin 3 & 5 on one end of the TB3 header cable. This forces the GC-Titan-Ridge to stay activated from a cold boot. Hot-plugging allows expansion ports to work but not the eGPU. A warm boot is required to get the eGPU going. Another crucial piece is Intel Thunderbolt Software version [18.104.22.1680]. In AIDA64 other than bandwidth throughput, look at how closely matched the rest of the numbers are.

Thunderbolt 3 has its limits. Computing tasks are the most appropriate use for TB3 eGPU technology. Gaming would depend on many factors. Of the four games I chose, three are not Thunderbolt 3 friendly. I will be testing the RTX 2080 Ti on this X399 next. Results would likely be similar in terms of dGPU vs. eGPU performance.

sorry to bother you but do you have Adrenalin 19.3.1 drivers from Bootcampdrivers.com by any chance?
The website don't store them anymore, only the drivers from Nov 2019 and newer.........
@nirvanich, I don't save these drivers unfortunately.
