Are they more expensive for equivalent hardware? I didn’t look at the current gen ones, but it used to be the case that consoles get a few years old hardware, developers just optimize better for those targets. And even still, there have been plenty of memes how you get a low-poly mess for a character in some console games.

PCs are only expensive if you go the “current best” route, but hardware advances are well in the diminishing returns category (maybe besides hardware-accelerated ray tracing), so you can very well play most games on mid-setting on a few years old PC which you can build from $500.
