Hi folks, I’m looking for a specific YouTube video which I watched around 5 months ago.
The gist of the video is that it was comparing the transcoding performance of an Intel iGPU when used natively, compared to when passed through to a VM. From what I recall there was a significant performance hit and it was around 50% or so (in terms of fps transcoding). I believe the test was performed on jellyfin. I don’t remember whether it was using xcpng, proxmox or another OS. I don’t remember which channel published this video nor when it was published, just that I watched it sometime between April and June this year.
Anyone recall or know what video I’m talking about? Possible keywords include: quicksync, passthrough, sriov, iommu, transcoding, iGPU, encoding.
Thank you in advance!
The performance impact is if you’re doing vt-d or some device mapping like that. Ive not noticed any performance loss when passing through the entire igpu.
Thank you, I’ll see if this new information can help me pinpoint the video.
