Can a Raspberry Pi 5 with 8 GB of RAM handle my needs?

I recently bought a domain from Porkbun (thanks to all of the comments on this post!) and I want to self-host some services myself. I currently have a Raspberry Pi 3 Model B+ and I'm not quite sure if it can handle these things:

  • A matrix homeserver
  • A lemmy instance
  • A website with static HTML pages
  • Privacy-respecting frontends (Piped, Redlib etc.)

I am thinking about getting a maxed-out Raspberry Pi 5 with a whole 8 Gigabytes of RAM. Is it worth it? I need a machine that is quiet, doesn't draw that much power and is overall pretty good for the money.

Edit: I bought this Mini PC instead of the Raspberry Pi 5. Thanks to all the comments!!

  • @AlexPewMaster@lemmy.zip I'm in your situation. At the moment on my RPI 5 I'm hosting (via docker) the followings:

    • lemmy
    • mastodon
    • gotosocial
    • peertube
    • pixelfed
    • grav CMS
    • matrix homeserver (synapse)
    • gitea
    • nextcloud And outside docker
    • teleport cluster
    • nginx for some reverse proxy
    • minecraft java 1.20.1 server

    For the sake of clarity, here is my docker ps -a | wc -l

    cyberpingu@vega:~ $ docker ps -a | wc -l
36
cyberpingu@vega:~ $

    Almost everything is behind a reverse proxy (on another machine, a rpi4 with KVM) with an argo tunnel. And again

    So if the question is "Is it enough a RPI 5"? The answer is yes, it is enough (at least for moderate traffic OFC). If the question is "I have to buy hardware: is a RPI 5 the best choice?" the answer may vary depending on many things. As you've been told, if GPIO is not a problem, maybe a minipc is better.
