Calling it ‘a cheat’ is somewhat weird.
The point is that a general purpose CPU is a bad solution for a personal computer.
The neural engine is about processing the ambiguous world that humans occupy so that the human doesn’t have to translate so much for the computer.
The GPU is about communicating visually with humans.
Point is that if you try to run a different OS, it will likely run slower, perhaps significantly slower than running macOS
If another OS doesn’t take advantage of the specialized processors, it will run slower, but only on specialized loads.
The future is keeping Apple "fresh", "cool", etc... While keeping product costs low to compensate for a falling market share.
Really says something that Apple is willing to compromise on long term hardware performance.
I don’t see any logic that supports this claim.
Apple, on the other hand, has been running rings around Qualcomm and other ARM vendors for a while now, and sharing tech makes it all the more important that they continue to be competitive.
