March 8, 20206 yr Hi I have a spare gaming PC following my upgrade to a Ryzen 7 3700X and 2080 Super earlier this year. My intention was to always turn the spare PC into an Unraid NAS, to replace my aging HP Gen 7 micro tower server that currently acts as my NAS. I am wanting to stream 4K content from Plex and therefore wanted to take advantage of the hardware acceleration feature which I believe is available on most linux / nas builds. My question is, is my spare GPU which is an AMD Vega 64 overkill for what I need it to do? I do also have an AMD R9 380x. Would this do the job? If so, does hardware acceleration work on an Unraid docker version of Plex, or am I best running plex in a windows VM and then passing the hardware through? Many thanks Scott

Some things to consider: Plex, running as a docker container on unRAID supports only Intel integrated GPUs with QSV or certain Nvidia GPUs (with a special unRAID build) for hardware acceleration. https://support.plex.tv/articles/115002178853-using-hardware-accelerated-streaming Hardware acceleration works great in the Plex/Emby/Handrake, etc, docker containers if using an iGPU or Nvidia GPU If you want to use an AMD GPU, your only option is to run Plex in a Windows VM on unRAID Ideally, 4K content should be direct played to clients that support it natively. 4K transcoding to 1080p or lower is extremely processor intensive if transcoded in software (CPU) and requires more GPU horsepower as well if handled through hardware acceleration. It is best to direct play 4K content or maintain a 1080p library for remote streaming or streaming to less-capable clients. Bottom line: Transcoding 4K requires high-end hardware in almost any scenario. Here's a rather blunt post on the Plex forums on the subject: https://forums.plex.tv/t/info-plex-4k-transcoding-and-you-aka-the-rules-of-4k/378203
