That nVidia card is going to have 5x the memory bandwidth. LPDDR5X is going to be rather low bandwidth.

(My guess is Intel's card is only going to have about 400 GB/s bandwidth.)

Last year's M4 max MacBook is 520GB/s and (I expect) that should be closer to 1TB/s in a year or two by the time they are using ddr5. It would be deeply embarrassing if they had worse performance than apples cheaper laptop.
