> Internally Apple always had an x86 build of OS X running.
This is true.
> Intel chips ran cooler, had better power efficiency and were way faster at a lot of things than PowerPC.
This is false, and so much so that it brings into question the whole comment. Heat from Intel parts was massively greater, and power consumption overall was greater on Intel parts for similar work. "faster" would have to include some specifics. A low-end Intel part would not beat an expensive PowerPC part, obviously.
> Leadership was actually super reluctant to switch and it took a demo from an engineer showing the massive improvement to convince them.
There were many demos internally and many casts of characters at the executive level, all along.
>If Apple is ready to switch to ARM they must have some impressive CPU.
