Ideal Emby Machine

So if i were to build a computer dedicated to hosting my Emby server, where should my priorities be?  Conversions and transcoding seems to be pretty heavily reliant on CPU threads, so what kind of CPU have you all found is ideal for this kind of load?  I know the hardware transcoding is still experimental, but Nvidia seems to hold an edge in that area.   How important is RAM to Emby?  It seems pretty much all loaded onto the CPU from what I can tell.  Thoughts?  Advice?  Been building computers 20+ years so i'm pretty experienced hardware side, don't hold back.  Would I see much improvement with a better build?  About 15users, regular transcoding, some moderate conversions.

 

Current Emby machine is as follows:

 

MB: Asus M5A97

CPU: AMD FX-8320 @ 3.5GHz

RAM: 16GB RAM DDR3@577MHz (11-11-11-28)
GPU: Radeon R9 380

 

Looks like the Conversion feature bottleneck is HD read/write speed?  Would changing the temp file path to the SSD make a difference?  Not sure how that is handled if it would still have to write then rewrite, or if it's literally used like temp RAM for the duration of the conversion.

The big question is always how much demand are you building, for? How much simultaneous transcoding over what bandwidth? I choose to use an M.2 SSD for my dedicated transcode drive.

set using the Transcoding temporary path option to your M2?  Assume at most 5 users transcoding at the same time, my UL is around 25, average user DL is above 75.  Looking to increase performance for several users on the road, stuck using slower hotel Wifi

Yeah, I use that drive for the transcoding path. What will you be typically transcoding? Just 1080?

yea almost everything is 1080, a few 4k things but not many.  I was just hoping for some info on what specifically Emby uses for what tasks so i know where to beef up the hardware

If you don't care about power consumption, a strong multi-core CPU is the best way to go. I have a Ryzen Threadripper 1920X in my server. I never have to worry about any transcoding. But a lot of people want to finagle with GPU transcoding. And then have to figure what does what and how much it can do. I used to do that, and got tired of it. A strong CPU, and don't look back. Forget 4k Transcoding, don't go down that rabbit hole, yet. But for what it's worth, my CPU has no trouble with it. Right now, ffmpeg can't tone map HDR, but when it does, I'm ready :)

with that low,of bandwidth on upload, I would focus less on the most powerful cpu for transcoding and prep low mb/s versions. Otherwise you’re transcoding for transcoding sake.
