I do feel like Nvidia is the only one with the right mix of market muscle, knowhow, and patents/licenses to pull of an ARM based competitor to Apple's products. AMD is doing some great things but can you imagine an M1 level product that sips power like a champ but has the graphical muscle of a proper 3070? The M1 Ultra is decent, but just doesn't compare to a proper dedicated GPU (on blender benchmark, the desktop M1 ultra seems to perform slightly below a laptop 3050).
