I haven’t tried the M1, but working in 3d, vfx, and video, I would assume there is no such thing as too much ram. If I could choose so, I would probably have 2TB.
Tunning extreme simulations(like we did in the black panther intro) is heavy!
Photogrammetry can be heavy, but also on the VRam(which is probably also a bottleneck on the M1s)
I’m interested in how the new iMac will be built. Maybe there is some potential for real pro work there.
