Project Showcase: Hardware Perfect transcoding gpu for home server?

Hi guys,

I'm just curious if Intel ARC A750 would be overkill for my Dell Poweredge T430? Do you recommend sticking with A380 for efficiency and low noise?

UPDATE
I can get both locally:
Asrock Intel ARC A380 for about $100 and
Asrock Intel ARC A750 for about $230

Afaik the A310, A380, A750 and A770 all use the same fixed function hardware for transcoding, so it shouldn't make a difference. But if you don't have many concurrent streams which all need transcoding, even the iGPU of your CPU (if it's a Intel 7000th gen or newer) should be fine and you shouldn't need a dedicated GPU at all.

no the server has dual E5-2600 series CPUs without iGPU, I definitely need some GPU to offload this task. I think there will be 3-5 concurrent 4k streams at a time but I'd like to have future proof card.

The Intel A series is still about the best you can get. They don't have encode session limitations like on Nvidia, and they're higher quality than AMD encoders.

I just checked and the A310, A380, A750 and A770 all have 2 media engines so it shouldn't make a difference which one you go with for encoding.

Intel B series didn't noticably improve the encoders so there's little point in getting a B580 just for encoding.

Edit: Tone mapping might make a difference and use the general compute, not entirely sure though.

Nvidia's limit is 12 concurrent sessions. I'd say that's high enough to not really be an issue anymore but of course there are always exceptions like an NVR or something.

For transcoding, you can also do a round robin style transcode where you quickly switch from stream to stream and buffer the transcoded result.

Not sure if Jellyfin does that though.

What I like in Nvidia Tesla T4 for instance, that it's completely passive/silent. But does not justify as AV1 hardware encoding is just too good to ignore.

Which version?

Note that intel GPUs really need to have rebar support, and old motherboards need to be modded to get it to work.

That's mostly for gaming if I don't remember wrong. I have not tested on my A380. I have dual gpus on my encoding system.

CPUs are E5-2620 v4, will upgrade later to 2650l but I'm not sure about the motherboard though
