Which would you choose: RTX A2000 or Arc A310 for 4K UHD Transcoding

[slacker]

I'm building a new server that will primarily host 4K UHD HDR content. In my situation I can choose between a Nvidia RTX A200012gb GPU or a Intel Arc A310 gpu. Server will run Proxmox with Jellyfin in a LXC container.

From these two options, which would you choose? I am looking for the best possible transcode/tonemap quality while at the same time supporting as many concurrent streams as possible. The Arc A310 is cheaper and supports AV1 encode, but the A2000 has 12gb of VRAM (vs 4gb in the Arc) and significantly more compute units for OpenCL tasks.

Thanks for any insights!

Vram matters more for tone mapping. The A310 should be able to handle 4 tone maps.

How many users will you have?

4GB VRAM on dGPU means 4x 4k->4k/1080p transcodes, more streams will cause memory swapping via PCIe and unacceptable FPS.
If you need more streams please consider models with more VRAM.

How may clients and how would they play the media? If they use something like Jellyfin Media Player i belive they wont need much transcoding unless you want them to transcode into hevc or av1 to reduce bandwidth usage.
