> For Apple, they have binning flexibility, with Pro/Max/Ultra, all the way down to iPads

The Pro and Max chips are different dies, and the Ultra currently isn't even the same generation as the Max. And the iPads have never used any of those larger dies.

> NVIDIAs flexibility came from using some of those binned dies for GeForce cards

NVIDIA's datacenter chips don't even have display outputs, and have little to no fixed-function graphics hardware (raster and raytracing units), and entirely different memory PHYs (none of NVIDIA's consumer cards have ever used HBM).
