Its wall power without cpu encoding with cpu its ~140W.
But i can agree results are good but we need also to remember Samsung 8nm [rtx 3090 node] is 4 years old so 2 generations different from TSMC 5nm 4090 will be probably on 5nm node in few months and presumably will have 3x teraflops (probably 3x tf32 precision but it could be fp32 using 2/1.5x(?) more power).
(also I'm not sure about optimization it was write by apple employees and apple likes to drop open source support and focus on proprietary software)
