Had some time this afternoon to test out the new 3.1 alpha on some demo scenes. (very excited, thank you Apple and Blender devs). I didn’t compare to any previous GPUs (laptop or desktop) from OpenData etc, as they don’t really compare with Cuda and Optic etc. So all results are from Cycles CPU 3.0 and 3.1 only, as that’s what we had before.
Specs:
16in MBP - M1 Max - 32core GPU, 64gb RAM
High Power Mode = ON

Observations:
I had the MBP plugged in all day, and during these render tests, it appeared to use 20% battery whilst being plugged in - almost like it was using the battery faster than it could charge it. Never seen that before, might be because of High Power Mode, but need to test further.
Edit: Now with more accurate percentages ((old-new)/new*100%)
