Answer 1

Doom can run on a Raspberry Pi Zero which costs $15. It’s a tiny general purpose computer with a processor, memory, ports and very basic version of Linux.

Maybe a smart fridge could get away with half the memory and only one port, but at $15 it’s cheaper to buy an overpowered chip than develop something in house.

The Raspberry Pi is aimed more at hobbyists, but there are hundreds of companies making similar mini computers for manufacturers.
