FWIW: raspberry pis (the 4 series) sucks in 15w which is why it’s so bloody difficult to power them through standard USB power adapters (which go up to 12w).

So, not hundreds of times more power hungry, but definitely 2-3x

Just to note that's peak power consumption. They idle between 1-4W, or if you're running a PoE HAT, 4-6W.

A RPi is not equivalent to what most would use as a COTS router, which includes a GbE switch and some kind of modem (DSL or cable). The latter on its own needs a few Watts.

On the contrary, OpenWRT and a good CM4-based board allows the Pi to run pretty well as a gigabit router :)

That’s not much of a router with just two ports and no WiFi.

No CM4 and accompanying carrier board needed . A regular RPi4 with a USB3 gigabit adapter makes for a good gigabit home router. I have been using one as my home gigabit router for the last 14 months without any issues.

As another commenter already pointed out, this is peak power consumption. A Pi + external HDD runs me to 12 W max in live use. Less if the drive spins down.

yep, which makes them a pain in the ass to efficiently cool down without active cooling (=fans)

My passively cooled RPi4 with 8GiB RAM + 1GiB/USB ethernet dongle working as a 1Gb router never goes above 50 degrees C (all-metal case from aliexpress).
