Yeh A380 arc really shines here. A couple of unsolicited notes if you go that route.

Ffmpeg > 6.0

VAAPI api is the winner for encoder, libsvtav1 is good too. - libaom-av1 is REALLY slow.

intel-media-sdk is needed - at least in debian, the free version in bookworm and testing repos is perfect - the non-free version mangled the files Decoder support in hardware is a thing to watch out for. (Plex+AppleTV had to have a profile set and forced on it, but that was really simple)

At the moment, I’m running three encoding streams simultaneously and it uses around 95% of the GPU BUSY stats - I don’t strictly know if that’s the best metric to measure against, but it is good enough for my half-arsed efforts.

Given the price I’ve seen the 750’s on sale for, it wasn’t that much of a reach to put a 750 in the server as well, but it was a physical space constraint plus once I’m finished the encoding effort, it would be way more than is ever needed for on the fly transcodes or one offs. Plus there are low profile A380 variants and it doesn’t require an extra power connector*.

*Turns out the Asrock one I have does require an 8pin - but it looks like the low profile version doesn’t. So maybe discount that point

6.7 on desktop 6.5 on server

Pretty good. I’ve got an a380 running in a media server that is just fkn amazing. And a 750 in my desktop.

I did VFIO on a nvidia 3070 and VMed Windows, but after a bit I just didn’t go in to windows and ran most games I play on the 750. Runs at 2560xwhatever the 16:9 other one is really well.

The games I’ve been playing are mostly CS2, BG3 - nothing super tough, but both >60fps, no issues. I haven’t done any benchmarking or equivs though. Otherwise other less graphically intensive games of course have no problems.

BG3 earlier had vulkan issues with some severe artifacting, but that was around launch.

These days, not even remotely a problem.

For the a380, I’m doing transcodes of some all x264 to AV1, and apart from some funkiness around the open intel-media-sdk vs closed, where the closed sdk spat out complete garbage. It handles the transcodes amazingly well for such a cheap little card.

I honestly never thought I’d say that Intel of all people could produce a GPU that was great… but Arc really is great.

The two cards set me back about $350 all up and the grand joke is the 3070 is sitting there kinda doing nothing these days.

The desktop system is Arch linux and the media server is Proxmox with passthrough to debian.
