I can get the implications for desktops; Apple have gone 68k --> PPC -->X86_64 already, now they're going to Arm64.
Now my RazPi 4 (4 core A-72 Cortex @ 1.5Ghz with 4G or ram and an sdcard for a disk) isn't a power machine, but afaik that's about 40nm wafer Fab, and simply using framebuffer, it outputs 2x4k hdmi @ 43fps, I'm told
Reduce that to 7 nm wafer fab gives you 3.5-4.5Ghz, 12-16 cores and bigger ram, throw in an SSD and an Apple video GPU that's a whole different ball game.
Now Arm64 (=aarch64) Linux systems are already out there. MacOS is based on BSD, so we haven't a long way to go to get linux on the new Macs.
This interests me because whenever this present laptop bites the dust, I intended to buy a desktop once, and keep it. I reckon I can, because we're pretty near what you can get out of silicon anyhow. Replace parts if they go. And I don't need some track-your-every-move OS; I can use linux.
Has anyone any insights, or experience with Mac booting?
