Depends, you can set it up a few different ways.
-
you can set the dns so each subdomain resolves to a different port with your ip, in which case your router can forward that port to any local address on your network with port forwarding rules.
-
reverse proxy, this is most common. You use a service to do the translating for you. Your router forwards all requests on port 80 and 443 to your reverse proxy. The reverse proxy takes requests for subdomain1 and forwards it to the associated ip/port locally.

Nobody was really answering, but steamos makes tweaking the effeciency easy. It should be like the steam deck where you can tweak the tdp limit for the cpu and setting clock speed for the gpu. I believe this currently only works with amd cpu/gpu, but I believe they’re working with nvidia.
