I feel like somehow my big Linux desktop with a Ryzen 7950X and 64 GB of ram feels less "snappy" than my M2 Macbook Air running Asahi when doing lightweight tasks, despite the big Ryzen being obviously much better at compilation and stuff. I'm not sure why and my guess was the RAM latency. But maybe I misconfigured something in my Arch Linux...
It has a Ryzen 9900X, 64GB of DDR5, AMD Radeon RX6600XT, 2x2TB Hanye NVMe, ROG B650 ATX motherboard and 850W power supply.
I bought the system mostly to increase the single core performance from the Ryzen 5 3600 I had before. As well as to get rid of all the little 256GB SSD disks I had in the previous one.
If I go look up an arbitrary 850 watt supply (seasonic focus gold), it looks like it wastes about 10% plus 5 watts anywhere from 0-60% load. So extra capacity doesn't hurt that one.
