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.
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.
You can check out the tool here.
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/
same with all modern pcie 4.0 or higher gpus
rebar is now standard
