I would love to see the results of a 3D chip with a powerful iGPU. Not sure if it would work, but if it is possible, why is AMD not doing it? Would it cannibalise 100-200 eur GPU (they are already nonexistent anyway).

Hijacking this thread, sorry OP. I just wonder why all ARM devices need a specific bootloader and a tailored OS imaged to install the OS. Not the case for x86, so I assume it has to do with the CPU extensions and such? Seems like the Cortex cores also support different ops from version to version.
