I’ve given up on both and use Apple Silicon only. AMD and Intel are simply too power hungry for how slow they are and can’t optimize for power like Apple can.
The hardware is impressive - tiny, metal box, always silent, basic speaker built-in and it can be left always on with minimal power consumption.
Drive size for basic models is limited (512gb) - I solved it by moving photos to NAS. I don't use it for gaming, except Hello Kitty Island Adventure. I would say it's a very competitive choice for a desktop PC in 2025 overall.
Nuc 9 averaged 65-70W power usage, while the m4 is averaging 6.6W.
The Mac is vastly more performant.
