Blender is still 3/4 times slower on ultra compared to rtx 3090 according to people testing it

34s on ultra (64 core gpu) vs 11s on rtx 3090

So 3 times slower but taking ~4 times less power (350W 3090 70W ultra [on 48 core gpu so about 90 on 64 cores])

Sounds about right, it's not magic. AFAIK the Metal support in Blender is not very optimized yet (it's brand new) but even optimized I don't expect it to come close to an RTX 3090. I still find the results amazing, for the amount of power this thing needs if it reaches 2x slower after optimizations, that's massive. Don't forget that the Ultra also includes the CPU and RAM in the power consumption.

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)
