I do really think it reflects the Max silicon being thermally problematic, there's just not enough headroom to improve performance. Also, for the M4 it look like Apple has started providing separate battery life estimates for Pro vs. Max, and the Max has 12% less (21 hrs vs 24 hrs for the Pro). That extra power is going somewhere, and part of that somewhere is heat.
It looks like getting a Mac laptop for the new job is a no go, so I’ll have to get my own before the next family trip, which will be around May. Enough time to do more research and watch for deals.
DxO and LR sees limited by the speed
of the Neural engine for denoising, so no big difference between any of the M4 variants.
Apple did specifically call out denoising in Davinci Resolve being realtime on M4 Max, that is something my low end M1 Ultra completely fails at.
Whichever model I get, it needs to have a fan, I’ve been using my wife’s M1 air during this weeks vacation and it thermally throttles hard when importing a lot of pictures (precapture, yay!) and once it’s hot, it stays hot. It takes about 10 seconds to load a 100% view, with both smart previews and 1:1 previews already present!
When I say ‘a lot of pictures’, I’m talking about this:
When using crop mode and cRAW, the R5II can easily sustain a 500 shot burst and the 100-500L is sharp enough to resolve details in the resulting 1 megapixel image:
