Will this work for 4k transcoding?

Plex Media Server Desktops & Laptops

I just got offered a MB with dual Xeon 5645’s for my older 1151 MB and some Ram. Monetarily wise his is worth more than mine, so Im considering it. My big thing is I want to ensure that those two CPU’s would be sufficient for a 80+mbps 4K with subtitles transcode. My 6700k struggles sometimes. So i have been wanting a home server build. I have a XL case for it to go into along with 6-7 fans. No gpu. Do you think it will be able to handle 4k transcoding with subtitles? My media doesn’t always direct play to my tv because of the subtitles I think.
I can get 24 GB of ECC memory for 35$ on ebay, and a 40-60$ PSU from a buddy. So all in all, if I bought myself the gaming case ive been wanting, and spend an additional 100-150 on extra parts, I could have what seems would be a great 4K plex, minecraft, etc… machine.
Thoughts? Is this enough?

nope.

aside from energy costs, compare the single thread rating/cpu mark.

subtitles are single threaded, and your current cpu is over double the single thread speed.

as far as 4k, even more no. per plex recommendations you need cpu mark ~17000 per 4k transcode.

To add to Tekno,

  1. i7-6700 (SkyLake) = 4k SDR
  2. i7-7700 (KabyLake) = 4k HDR ( You want KabyLake or better )

I have the i7-7700 in my QNAP TVS-1282-i7-32GB.
I ran 6 concurrent transcodes of physcial disc remux (I rip my own here) to everything in the house. There was still plenty of CPU left to run at least 4 more.

This is no longer about throwing big iron at the problem. It is entirely about using the right tool for the job. Throwing older, big, iron is not the best IMHO approach (I wouldn’t want my dentist using a pneumatic drill in my mouth haha)

Nope. do you have hw transcode enabled? If you wanted to trade your way to something more appropriate, trade your 6700k for an i5-7600k or upgrade to a i7-7700k. kaby lake series for the improved iGPI. Single thread is important. Noise and power usage is also usually important.

I really like the value I get from an i3-8100, i3-8300 or an i3-8350K low cost CPU’s with great hw transcode support and good single thread performance (expecially in the i3-8350K) used they go used for 100$-150$ work on the latest intel systemboards (60$-75$)
