The 580X had four DisplayPort connections routed to system. Does the 5500 chip normally have fewer DisplayPort outputs (4 instead of the usual 6)?

If the W5500X is a Navi card that supports Display Stream Compression (DSC) then it should allow connecting two Apple Pro Display XDR displays (unless there's a performance limit on pixels/s, or it doesn't support DSC?). Apple might be wrong here like they are with the Vega II which supports three XDR displays instead of just two.
