I have read multiple article but i have yet to see anyone mention it.

Isn't this about Security more then anything else?

IF it is about power, Intel SoC uses very little power during Power NAP. And any saving by switching to ARM should be negligible, when you consider the memory and I/O needed during Power NAP.

If it is about cost, Apple could have worked with AMD on Mac. I am pretty sure Ryzen and Vega works better on dollar / performance / Power. Especially on the Desktop Mac. Considering AMD has done special chip with console, I dont see why Apple couldn't use this model as well.

Since Intel's CPU has IME which Apple has no control, would that be a reason? Apple taking security in their own hands.
