@CaseySJ So Can I assume with a good probability that we will have full support of NAVI21 in 11.4? If it's so which the most compatible card at your experience among the RX 6800XT models?

Navi 21 (RX 6900 XT) is already supported in the 11.4 Beta 1, as is the RX 6800 XT. With so few people having them it is probably too early to say which, if any, have any problems compared to others. They is currently no support for the RX 6700 series but it is expected to come in a future beta, only Apple, and AMD who write the drivers for Apple, will know for sure though.

@Azimuth1,

This is a good question because not all NAVI 21 GPUs have Device ID 0x73BF. @byteminer, who posted several times in this thread, has a particular RX 6900 XT (or XTX?) with Device ID 0x73AF, which is not supported.

It would be best to avoid the new XTX models for the time being.

The Board size of these incompatible models is larger as well. It’s a larger PCB size for the ultra custom versions.
This appears to be related to the device ID.

I use a Sapphire 6800XT Nitro+ SE works great on my x570. Haven't connected it via the USB C . But works well with HDMI and DP . Well until I tried a different patch for AMD and now only using it on HDMI but get nearly 190K on Geekbench metal

Can you verify if your Sapphire 6800XT Nitro+ SE GPU have Device ID 0x73BF? Thanks in advance!

actually XTX is older performance models the new performance models ones are XTXH and most of the high end cards that came out in april 2021 use this variant such as Red Devils and Sapphire toxic
