I am in the early stages of planning for a powerful (hopefully) Plex server and right now I am looking at different CPU options. I haven’t decided yet whether to build the server out of new parts or buy a second hand Dell or HP server on eBay and just add components as needed. I think I will do whatever gives the best results for the money.
The server will also be used for surveillance video and as a DAW server, so it needs some extra capacity. Plex would be the primary focus for this server though.
Right now I am trying to decide on what direction to take regarding CPU configuration for the server. It seems to be one of the most important things to decide early on since motherboard, chassis, RAM, Raid cards, etc depend on this decision.
What do you think of the CPUs below for Plex?
- 2 x Intel Xeon E5-2667 v2 Q1 2014 - (3.30GHz, 8 cores), Passmark Dual CPU: 21600, Single Core 1941, Price 2xCPU: $300-$400 (eBay)
- 4 x Intel Xeon E7-4890 v2 Q4 2015 - (2.8GHz, 15 cores), Passmark Quad CPU: 34472, Single Core 1780, Price 4xCPU: $400-$800 (eBay)
- 1 x Intel i7 10900X Q4 2019 - (3.7GHz, 10 core) Passmark Multicore: 23264, Single Core: 2785, Price: $800
- 1 x AMD Ryzen 3950X Q4 2019 - (3.5GHz, 16 cores) Passmark Multicore: 39390, Single Core: 2745 , Price: $700
I tried to include four CPU configurations that are quite different from each other and that also differ in age.
Would you recommend one over another and why?
If I go for a 2x or 4x CPU configuration I will probably start off with a second hand Dell or HP server. Is that a good idea? Are there any advantages/disadvantages to that compared to building my own from scratch? Possibility of adding well integrated separate storage chassis?
I primarily want to create a Plex server that is powerful and will last a few years. Cost will of course matter - but it will not be the only consideration. Power consumption and heat is not a big factor. Space used by the computer chassis is no big issue. I will probably rack mount the chassis.
Would a 4xCPU Dell server yield better results than the Ryzen or is it just silly to even consider it, because the Ryzen would be faster and cheaper anyway?
What would be the pros and cons of each of these CPU-configurations for Plex use? Is there a benchmark (or performance value) that would be usable for measuring Plex performance and approximately how well would they each do?
The 10900X is the only CPU with Quick Sync. Does this make a huge difference in transcoding performance? What if I add a GPU to the other CPU options for HW transcoding? Would that be possible and possibly even faster than a 10900X with Quick Sync?
Lots of questions. I know… Any ideas or thoughts to help me narrow down CPU alternatives would be greatly appreciated.
