![]() ![]() Thank you for the advice about the passmarks - I'll use that as a rough guide in future! I think I can safely make the assumption that the split between direct playing and transcoding is 50/50. I was being dumb and assuming all devices were direct playing because all the devices in my home do but after checking, there are a few external users with hardware that wasn't direct playing - probably why my CPU is having a hard time. Thank you so much for the detailed reply! Hopefully, all your Plex clients can play 4K directly or you have a 1080p library for remote streaming. If you are talking about transcoding (when needed) 4K/HEVC content, throw all this out the window because Plex says you need 17,000 passmarks for a single 4K/HEVC/10-bit transcoded stream. This whole discussion has centered on 1080p content. All direct play? A mix of direct play and transcoded? All transcoded? ![]() The bottom line is that you have to have a good idea how those eight streams of content are going to be delivered and plan accordingly with either CPU or GPU. That would mean at least a Ryzen 2700X or above. If you are going to stick to CPU transcoding, when transcoding is necessary, and you want to have the CPU overhead to handle 8 streams transcoded, you would need a CPU passmark score of around 18,000 (16,000 for eight 1080p streams + 2,000 for unRAID overhead). For direct played local content (no transcoding) it should be plenty. With a supported Nvidia graphics card in the system, the transcoding is offloaded to the GPU and the CPU passmark score does not become such a big concern.ฤก6GB RAM could be a bottleneck if you have other system activity plus multiple transcodes taking place however, that depends on the source format, target format, bitrate, etc. Your Ryzen 5 2400G has a passmark score of 8953, that is enough for the CPU to transcode up to 4 streams and leave barely enough overhead for unRAID itself with no other activity on the server. Transcoding recommendations from Plex are that each 1080p transcoded stream needs about 2000 passmarks. ![]() However, if content is being transcoded (converted to a different format or bitrate the client can play or streamed remotely), then that is, in fact, the limit of the Ryzen 5 2400G. If you are largely direct playing content locally, I am surprised it can't handle more than 3-4 simultaneous streams. Ideally, I don't want to change the motherboard so I'm hoping you can recommend something last-gen that's compatible and will allow more Plex streams. ![]()
