Ask HN: What’s the advantage of higher memory bandwidth in Apple Silicon chips?

I checked the unified memory bandwidth rating of the Apple Silicon chips:

- M1: 66.67GB/s - M2: 100GB/s - M1 Pro: 200GB/s - M1 Max: 400GB/s - M1 Ultra: 800GB/s

The question is, which app or task will take advantage of higher unified memory bandwidth?
