You probably meant a Pi 1 which even though does share the name is in terms performance is a lot more than 10x better, see e.g. https://the-diy-life.com/raspberry-pi-drag-race-pi-1-to-pi-5-performance-comparison/

I’m not saying anybody needs a RPi 5 … but it’s also not fair to compare to something related yet different.

I’m not sure as that’s about Steam the client though not on Proton thus Wine, which I bet will keep on supporting 32bit apps.
