Should I add a GPU to my server to allow transcoding of 4k files?

please read entire thread @ Plex, 4k, transcoding, and you

to answer the subject

  • YES

to answer your questions

  • there are few half height single width gpus which will support 4k, the quadro p400 can do ONE 4k transcode, if that is enough for you, they are pretty reasonable.
  • i7 4770 is not enough for 4k/hevc, you need at least a 7000 series intel cpu with an intel 600 series igpu.

to AVOID transcoding

  • make sure you switch to dolby digital/dts 5.1 or stereo audio
  • subtitles can also cause transcoding, try disabling them to see if that helps
  • get an nvidia shield which can direct play pretty much everything. you still need a 4k/atmos receiver for HD audio.
