To me it would make sense if the first Macintosh to sport Apple’s ARM system on a chip was the basic MacBook. It’s entry level enough to support up selling more powerful machines, and down low enough to write it off if the horse power cells to wow everyone’s eyes out of their sockets.
“Looking at these rumored specs, it honestly looks like Apple wants to repurpose the discontinued 12-inch MacBook to sport its own A14X Bionic SoC. Since the A14X Bionic is expected to be made on the 5nm process and not have a ridiculously high TDP, the 12-inch MacBook’s chassis should be sufficient to cool the chip“
Which would also be inline with modern Apple and Samsung devices. Not to mention, if it’s not busted: why fix it?
