2013 Mac Pro + Raser core X + Nvidia RTX 2080 doesn’t detect card.
My set is like this
2013 Mac Pro (TB2->TB3)+ Raser core X + Nvidia RTX 2080+ OS10.13.6 high Sierra.
1.I made SIP unavailable.
2.I made Nvidia available and installed web driver with purge wrangler 5.1.
Mac could boot.
But Mac doesn’t detect card.
When I use AMD vega64, this system worked.
GTX works. But does RTX not work?
Pending: Add my system information and expected eGPU configuration to my signature to give context to my posts
There are no OS X drivers for the RTX cards, while High Sierra has drivers for the GTX cards, and AMD cards have native support. That should explain what is happening.
You should be able to get the RTX card working on Bootcamp.

Unfortunately it's likely not going to work in Boot Camp either. The late 2013 Mac Pro has firmware that doesn't allow eGPU to work in Windows or Linux.
Could you elaborate on this? Would it also not work with an AMD card in the eGPU enclosure?
No eGPU would be detected in the 2013 Mac Pro. There’s software workarounds for macOS (Purge-Wrangler and automate-eGPU EFI). For Windows Boot Camp, the only way so far is through MacVidCard’s GPU firmware flashing service for Nvidia. Nothing for AMD that I’m aware of.

Do you have any cards with narrow BAR values? I recall that, for example, a Quadro NVS 295 should be plug-and-play, both macOS and Windows Boot Camp.
@goalque How do I determine BAR value for the graphics card?
With UEFI Shell's pci command which displays device list/configuration space. You need to give Bus, Dev and Func of the eGPU device as parameters.
Here's one screenshot, the lines under "Resource Type" are BARs (base address registers, not eGPU in this case) and you can calculate how much memory it needs.
