I've got two computers in my workstation space:
Dell Optiplex 7020 - Intel Core i7-4770 @ 3.4Ghz (4 cores), 16 GB RAM, 512 GB SSD + 1 TB SSHD, Radeon RX 560 w/ 4GB VRAM
Apple MacBook Air - M1 processor @ 3.2Ghz (4 performance + 4 efficiency cores), 16 GB RAM, 256 GB internal SSD + 1 TB external SSD
I've mainly been using the MacBook Air as my daily driver ever since I got it, and have no complaints outside of needing to buy an external adapter to plug it in through my HDMI/USB KVM switch. As far as speed goes, this thing absolutely flies. The graphics performance is roughly on par with my PC's Radeon RX560, although admittedly most games that I've run on it so far are not M1 native.
