I currently have my main unraid server, itS primary use is a file server and the occasional Plex use. 
 

Yesterday I installed 4 4k 8MP Cameras to the house, and am running blue iris and frigate. I have a coral for frigate so CPU resources for that shouldn’t be too high.

 

blur iris however is tanking the cpu, and I’m fairly confident a upgrade if required.

 

I currently have Ryzen 5 2600, b450 motherboard and 32gb ram. cup is pretty much pinned constantly at the moment. 

 

I’ve seen a few good deals on Ryzen 5 5800X and Ryzen 9 5900X

Price isn’t a huge issue, I’d just prefer to have plenty of headroom for future additions should I add further to it.

Why blue iris and Frigate?

Can you use more cores? 5900 or 5950. In 8 core maybe 5700? Understand the demands of the software, it'll tell you what hardware will work best.

I also run Frigate (using a google Coral TPU) and BlueIris.  I am running frigate on a home assistant N95 nuc and BlueIris on another n97 based nuc (mini pc) so they are not running on my unraid server.  However, the n97 handles all of my 5 cameras easily in BlueIris.  2 of my cameras are 4k, and the other 3 are 2k.  As you can see from the image below, my cpu load is rarely an issue.  In fact, it seems to run around 25%-30% cpu load most of the time.

 

I would suggest you look at the structure between frigate and blueiris.  If you are like me, I use frigate for object detection and alerting (with the coral tpu).  I use blueiris for 24/7 continuous recording of the full resolution streams only.

 

If your use-case is similar to mine, I would suggest you look at blueiris and make sure you aren't doing ai or motion detection and have it set to direct record to disk (i.e. no transcoding).
