DisplayPort 2.1 (which the monitor supports) provides sufficient bandwidth for 7680x4320@60 Hz 10-bit without DSC when using UHBR20. The press release unfortunately doesn’t clarify whether the monitor supports UHBR20 or only the lower UHBR10 or UHBR13.5 speeds. Of course, the GPU must also support that (Nvidia RTX 5000 only at the moment, as I believe AMD RX 9000 is only UHBR13.5).

I believe you're right regarding AMD's lack of UHBR20 on its cards. Fingers crossed for their next gen!

AMDs current workstation cards do support UHBR20, just not their consumer cards, even though it's the same silicon. Artificial segmentation on GPUs is nothing new but segmenting on display bandwidth is a strange move, especially when the market leader isn't doing that.
