Can somebody explain how is M1 going to work on larger GPU tasks (rendering, encoding etc) with it's memory bandwidth
M1 total memory bandwidth is 68.2 GB/s (128 bit LPDDR4x-4267)
AMD Radeon Pro 5600m memory bandwidth is 394.2 GB/s (2048 bit HBM2)

They were waving their hands around a bit saying that in addition to on-package RAM with high bandwidth, they have done optimizations inside driver, OS and APIs to eliminate 1 or even 2 or more RAM to RAM copies for common tasks. So maybe there is a higher effective bandwidth when comparing to Wintel machines. It was very vague. Would love to read a detailed article comparing the systems.
