The high multi-monitor power draw issue affected RDNA2 for some in early driver releases but they managed to iron it out so I expect the same here.
Yes and no. Yes it improves but even on rdna2 now idle power draw is relatively high. As of today, multi monitor idle and video playback power draw on the 6800, 6800xt, 6900xt and 6950xt are all 50% to 100% higher than an rtx3090. So there is clearly room for software improvement and not just a bug fix
Multi monitor idle:
6800xt/6900xt/6950xt: 41watt
7900xtx: 103watt
Rtx3090: 31watt
Rtx4080: 23watt
YouTube video:
6800xt/6900xt/6950xt: 44watt
7900xtx: 88watt
Rtx3090: 28watt
Rtx4080: 20watt
