@mkzayar, The VRAM would be the reason to buy over a 6800XT only, in my opinion.

 

2020 iMac 27" / i9 10-core / 128GB RAM / AMD 5700XT Pro 16GB / 2 x Razer CoreX with 6800XT 16GB + 6900XT 16GB -- Own build Threadripper 3970X 32-core / 128GB RAM / 2 x RTX 2070S 8GB + Quadro M4000 8GB.

Node Pro + W6800 + 11.4 does not work...

egpu icon appears once, but in a few second, icon disappears. 

 

Node Pro + Pro VII + 11.4 works well ( without karnel panic at eject..)

 

Is there any ideas??

What is the PCI ID of the W6800? You can check for it under System Information > Graphics/Displays. It's possible you can borrow the drivers of RX 6800/XT through the use of @mac_editor's Kryptonite.

I read on the Apple Support Forum that the RX 6000 series is supported with Big Sur.

I am currently using Catalina, and was wondering if my OS version would be compatible with the RX 6800 XT.
I am also concerned if upgrading to Big Sur might cause FPS drop.

Please help!

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

@poptonez, thanks for confirming MacOS driver support in 11.5 for AMD’s new Pro W6800 card with 32GB of GDDR6 / ECC memory. 

Please post a Build guide for your MBP setup when you have time. 👍🏻

@nicholas_mulyawan, MacOS Catalina is not compatible with the 6800 XT

There is a wireless mouse polling rate issue causing FPS drop in Dota 2 on Big Sur.

But it sounds like an adjustment of the mouse polling rate settings solves the problem:

After what feels like a year of trying, I finally was able to buy a reference AMD Radeon 6000 series card at MSRP. The local MicroCenter had an open box Gigabyte RX 6900 XT. I was second in line this morning and this card is now mine. Also I bought the ROG Flow X13 + XG Mobile which arrived today. Look at the drastic difference in size between XG Station 2 vs XG Mobile.

Apple always knew AMD was acting sketch AF regarding 6800 XT / 6900 XT cards.
