30 vs 40 GPU cores for 12K BRAW editing and grading?

M3 Max with 14 vs 16 CPU cores too, but I wonder if that GPU difference will make any of a big gap for 12k footage on Resolve?

12K is running fine here in an UHD timeline on a far lesser machine. But more GPU cores will speed up complex tasks, like NR and all the other 'neural' ones.
