M1 Ultra should be a monster at rendering because of available VRAM.
Redshift has their Moana Island Scene and it does crazy good on M1 Max.
2 x 1080 Ti = 77m
2 x 2080 Ti = 34m:17s
1 x 3090 (24GB) = 21m:45s
2 x 3090 = 12m:44s
M1 Max (64GB) = 28m:27s
M1 Ultra would probably halve that to 14 minutes.

A Redshift developer do mention some issues with the default benchmark here.

Please note that the benchmark is using 128x128 blocks which are not ideal to the M1 chips (due to their pretty high latencies). So the benchmark (as it stands today) might not show you particularly good scaling. The same is true for the M1 Pro/Max - but to a lesser extent.
As a stopgap solution I might look at adding a blocksize parameter to the benchmark. Or force it to 256 or larger if apple silicon is detected.
