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?

Like others said an Intel CPU with iGPU, alternatively the cheapest Intel Arc GPU (A380?) supports the latest spec of Intel QSV as well.

A310 is the cheapest.

I wonder how well it does for transcoding on older computers without ReBAR, since apparently gaming on it is straight out broken without ReBAR. As in, it would actually freeze for a second or so every now and then.

Encoding engine basically requires it, so you’d need to implement a hack or something. https://www.reddit.com/r/IntelArc/comments/189cgsm/intel_arc_h265_encoding_performance_and_resizable/

Shit, this kinda screws with my plans to use the A380 as a transcoding card for my server.

same with all modern pcie 4.0 or higher gpus

rebar is now standard

You can enable REBAR on older machines with a UEFI hack.

It’s been part of the PCI spec for ages but Nvidia and AMD only started using it recently.
