The machine I'm posting this from is my Ryzen 2700x with 8 CPU cores, 32Gb of memory and an SSD Raid Array on an ASUS ROG RX-570 STRIX mobo. It's a damn' impressive machine.
I have been following Apple's M1 chip developments and am really impressed by their performance. Seeing that Linux has been ported to it, I'm seriously considering purchasing one. I'm a Linux fan, have been for many years. Kicked Microsoft fully to the curb a few years ago now with the sole exception being my work laptop which was provided to me by the bank I work for.
As for nVidia/ARM, the more competition in this space the better. Intel got "fat & happy" for far too long and innovation suffered greatly as a result. AMD finally coming up with the Ryzen CPU's shook Intel awake a little bit, Apple's M1 chip's performance rocked Intel, let's see if nVidia/ARM can push Intel closer to the cliff or if Intel finally, fully wakes up and starts innovating again instead of simply adding more cores/boosting speed of existing CPU's.
