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?

The 970 works for encoding h.264 only. My recommendation: If you have a 7th Gen Intel CPU with iGPU or later, use that. Otherwise, sell the 970 and get one of these (in this order):

Intel Arc A310
GTX 1650
GTX 1630
Quadro P1000
Quadro T400
GTX 1050 Ti
GTX 1050
Quadro P620
Quadro P600
Quadro P400

The Intel Card has the best encoder, followed by Nvidia Turing, then Pascal. I recently sold my 970 and got a 1050 Ti for the same price. Works great with Jellyfin. If you need to tone map HDR, you probably shouldn't get anything with much lower performance than that. If it's just some UHD to HD or h.265 to h.264 for compatibility, even the P400 will work well.

thanks for the tips! I am running a Ryzen 9 5950X, so it definitely needs a standalone GPU. I am going to be getting a 1070 off the kids’ computer once I upgrade them later this year, so I think I’ll just stick that into it.

Would really like to get the seamless transcoding to work so the whole family can use it without hiccups.
