Is it really necessary to use a Raspberry Pi 5 for Octoprint? If so, how much RAM is needed.
Weba @Frank_3D !
A Pi 3 is quite sufficient for OctoPrint. A Pi 4 also.
A Pi 5 can be considered as "too much of a good thing" 
I'm curious who made that proclamation.

I would actually tell you to NOT use a Raspberry Pi 5 as thanks to missing hardware encoders it's actually a worse choice than an RPi4 if you intend to attach a webcam to it as well.

Thanks, that sounds good! I still have a Raspberry Pi 4 in the drawer. Do you notice the difference between a Pi3 and Pi4 (with camera)?
I'm using an RPi 3 with an RPi cam V2 and I'm happy with the performance. I'd use the RPi 4 in the drawer rather than buying a 3 or 3+.

What are the missing hardware encoders on the Pi 5 that are on the Pi 4? I recently acquired the Pi 5 and have used it on my Artillery SW2. Are you saying if I try to add the camera it just won't work?
The Pi4 has the advantage of being able to boot from USB. Thumb drives have a longer lifespan than SD cards, which really aren't made for the constant read/writes that an OS can require. I've got an USB MSATA daughter card for a Pi4 that I'm wanting to try out as soon as I get my New MIB Ender 5 up and running. I'm still getting parts for the planned upgrades that I'll put in during assembly first.

Actually, the RPi 3, 3+, 4, and 5 can all boot from USB. The RPi 3 is a bit complicated to get setup and has some restrictions but the rest are relatively easy.

H.264 is not hw accelerated on RPi5 at all, only H.265/HEVC is, they removed this feature from the hardware.
RPi 0-3 have hardware accelerated decode for H264, MPEG4, H263, and through optional codec licences for MPEG2 and VC1.
RPi 4 has the same hardware accelerated decode for H264, but not the other codecs. It also has a separate block for HEVC.
Nope, I'm using 4b, pretty sure you could do it with pie Zero 2w
I´m using Rpi1B, basic usage. Haven´t tried video yet but read it can cope with that too, albeit it ain´t zippy.
