Ryzen 9 with 16 cores and fancy-ish GPU is not really a mid-range setup, as I said, you can go lower with weaker components. (the other numbers I had at hand quickly were from way below the 1200€ mentioned in the comment I replied to, and I thought it was a useful upper mark). And in reverse, 20W peak is low for a laptop - my Thinkpad 480s (which I guess you can argue is not a mid-range laptop, but not exactly a workstation beast either) peaks more at 40. The desktop comparison to many laptops is more a mini-ITX based, embedded-graphics box with e.g. a quad-core CPU. There idle <=15W is realistic. (And the laptop idles at ~5, so still more efficient of course). And the range between for components inbetween that and high-end. Desktop is going to be worse than laptops, but people tend to overestimate how much power a desktop system actually has to use if it's built well. Modern CPUs are efficient at power-saving, PSUs have gotten better, ...
