looking nvidia gpu for passthrough

[pwn]

Hi, as in topic, what nvidia gpu you have in servers? I looking something but I have some trouble with radeons and I it would be nice to avoid it with nvidia. Gennerally nvidia is better cards for passthrough than amd? or it doesn't matter?

I consider about gigabyte rtx 4070ti super. Any chance to passtrough fail?

Those cards that require a NVidia GRID VGPU license, probably. I hope you already tested if your motherboard (and CPU) supports passthrough and has good IOMMU groups.

EDIT: Sorry, I though you were asking about NVidia server GPUs. I've had great success with AMD HD7750, RX570 (with vendor-reset) and 6950XT.

Oo I never heard about that license. There are any issues to run without this license?

Already I have rx 6400, ryzen 5 3600, 96gb ram and x570d4u server motherboard. Server works as truenas and media/gaming server. In other my topic I wrote about some issues with my two amd gpu. In short, was good (f.e. playing cyberpunk with any issues) and since few months isn't good - performance is poor... I back to proxmox 7 and is little better but cyberpunk is still not playable.

So maybe upgrade is needed or nvidia have better working drivers for passthrough.

Oh I see your edit now which vendor 6950xt you have?

I tested Asrock rx 6600 too but it have reset bug. Passthrough works fine but issues when restart etc.


I've read about vgpu (thanks for inspiration) because I never heard about this concept. I understand it as a posibility to run multiple vm with sharing one gpu to them. With that feature I can do own gaming cloud, right? with vgpu can I have multiple output? (dedicate every displayport to other vm?)

RTX 4070 Super have good price now but can't find any info about passthrough.

So assume, that pcie passthrough should be fine with rtx ( license are for vgpu ) ?

Edit:

I found that (it's reference card) rx 6900xt- what do you think? It's moooore cheaper than rtx 4070 ti super but same parameters...

AMD, no really, just AMD.

Not all of the 6000 series is perfect for passthrough: https://www.reddit.com/r/VFIO/comments/tq9j5v/need_help_compiling_a_list_of_amd_6000_series/

No, vGPU has no output. It's for enterprise hypervisors servers/cloud i.e. remote clients.

I don't know but I always understood that NVidia does not want people to use passthrough.

AMD ray-tracing is (much) weaker than NVidia and no CUDA support.But good open-source drivers on AMD that come with Linux. I assume all 6800 and higher work with passthrough, but I cannot give guarantees.
