Ideal setup for accellerated transcoding many streams 4k>1080p h.265

I’m having trouble finding good information on hardware transcoding performance and limitations in stream counts etc.

I’ve been through this thread:
https://www.elpamsoft.com/?p=Plex-Hardware-Transcoding

suggesting a few nvidia cards as great choices w/ the stream unlocker patch, but I can’t seem to find out much about AMD cards or Quicksync capabilities.

I would prefer to just use quicksync and buy an appropriate intel CPU for my needs, but I can’t find any info on how many concurrent streams etc on either.

My primary goal is transcoding 4k to 1080p live as well as in background for mobile devices. My current system is doing this is software and it crushes it for 1 stream, and a sufficiently high bitrate 4k video (~25Mbps+) can’t keep up to 1080p. I can do 2 1080p>720p transcodes but if those run in the background, my cpu falls apart. Time for a new plex rig.

So basically it comes down to, I’m I basically stuck getting a GTX 1050 Ti in my new system to handle a few h.265 4k transcodes or can a gen9+ intel CPU with quicksync handle this?

any intel processor from kaby lake (7xxx) that has a 600 series GPU or newer, can do 4k with quicksync.

As to how many streams, I don’t think anyone has done the research and posted it for quicksync or amd gpu.

On linux, nvidia cards are limited by VIDEO RAM (~1.3gig per 4k transcode). I don’t know how much that applies to quicksync.

And windows uses video ram different as well.
