It appears the new Radeon Pro W6800 is supported by macOS 11.4 and later. The device ID is present in the framebuffer driver. It's Navi 21 based like the RX 6800/6900 series. It appears the Navi 23 based Radeon Pro W6600 is not yet supported.
W6800 MSRP is $2249 so I'd say about $2500 for the W6800X MPX because the W5700X MPX is only $200 more than the PC version MSRP ($799).Would guess around $3500-4000 for an MPX version, if it's ever made available.
AMD Series 6000 GPUs are not supported with MacPro5,1, only with 2019 Mac Pro. While you can install and run AMD RX 5000 series GPUs in a Mac Pro 5,1 and run Catalina/BigSur (up to 11.2.3), when you install a 6000 series GPU the MacPro5,1 won't boot.^^^^The RX6700XT is not supported. Sorry! The RX6800 series requires OS11.4 or higher.
NVIDIA Kepler GPUs are still fully supported with Mojave/Catalina/Big Sur and the first two betas of Monterey.I know of no Nvidia GPU that will run in a MacOS past High Sierra 10.13.6.

However, as I have the card (and paid quite some money for it) I’d like to know if there is a chance of support of the Navi21 XTX cards in near future?
MacPro5,1 don't even complete POST with a NAVI2x GPU installed. We still don't know if it's a PCIe, chipset, CPU or Mac Pro firmware issue at this point.Hi folks ?
I am quite a newbie the Mac Pro community, but have already read through I think half of every (relevant) thread about the 5,1.
As @tsialex mentioned, the RX 6900 XT (in my case by xfx) won’t boot.

Yeah, I must have overseen that specific part of the list, thanks ?XFX cards have known issues with macOS in general. Scan this list and see that all XFX are "windows only" and other manufactures are both "mac and windows" compatible for eGPU. This is a good guide for starting with compatibility.
That sounds slightly like a downer. Well, why? Because I can? Apparently I don't, however. I had this card around 'cause of another project and wanted to try. So you say the best card to get is the RX580? How about the Pro VII? Or the Vega 64? Now I have done the Pixlas Mod I don't want it to be wasted. Right now it runs on a Frontier Edition and running well, although I have some issues with the OC boot screen. But I'm working on it.Why are you trying to use a $1750+ GPU on a machine from 2010/2012? Really seems like that money should be invested into newer hardware to take advantage. On MP5,1 there was generally little performance improvement between RX580's and the 5XXX series. The hoops to jump through for MP5,1 to boot latest OS alone make using latest 6XXX generation GPUs even more of a challenge.
Yes, I realized that after some troublesome fault finding when I thougt I broke the card. But I could verify it is not.MacPro5,1 don't even complete POST with a NAVI2x GPU installed. We still don't know if it's a PCIe, chipset, CPU or Mac Pro firmware issue at this point.
Thats quite sad. I already have upgraded my 5,1 to the max of RAM and CPU and wanted just the best for "my baby" (don't take me to seriously there ?).I have a hunch from what I've read with hackintoshes that is more than the MacPro firmware, but also CPU requirements and a NAVI2x GPU could never work with MacPro5,1. At this moment, I don't have any hopes with MacPro5,1 and NAVI2x GPUs.
Ahn?!?!?! What any macOS update will do to make it past POST?Thats quite sad. I already have upgraded my 5,1 to the max of RAM and CPU and wanted just the best for "my baby" (don't take me to seriously there ?).
But I won't give up my hopes. I'll have a try with the next updates ?
I will make your day with this one.. Curious about your opinion Andrew..The Pro VII, the newer Workstation GPU, not the older gaming version, should be the most powerful GPU you can put in a 5,1. It should be supported in Mojave, but I don't know if anyone has actually tried it yet.
That's interesting. I added the info to the first post. It appears that is only the version from AMD that is available to system builders only. The PowerColor version is supported.It seems the liquid cool 6900XT has a different device ID which doesn't supported in macOS.
May be you can double check this info, and add to post #1 accordingly.
