Self-hosted Jellyfin CPU or GPU for 4K HDR transcoding? (lemmy.one)

Hey everyone, I'm building a new server to run Jellyfin (with a few other services like Pi-hole) and I'm stuck on GPU or CPU transcoding.

My main concern is smooth 4K HDR transcoding for 1 stream. I've been reading mixed advice online – some people say a strong CPU with good single-core performance can handle it, while others recommend a dedicated GPU.

Should I focus my budget (~$1000AUD/$658USD) on a good CPU, or spend some of it on a dedicated GPU?

It's not Jellyfin, but here's my N100 simultaneously doing two 4K HDR transcodes with tone mapping enabled. Neither stream had buffering.

So it's definitely a capable chip, but might be dependent on transcode settings.

Yeah after seeing this and another very detail answer it looks line my settings are too demanding and that is causing a slowdown. Since i do direct playing on everything i might just turn them down for the one friend who seems to be always on the weirdest player that needs transcoding. Thanks all!!
