Hey Guys,

Currently I have BI on a I9 9940 14 cores/ 28 threads 32GB ram Top of line ssd Gigabyte x299 gaming 7 MB and an amd RX580 video card.


I run about 30 HD 6mp cams (Maximum frame rate and bitrate) and never exceed 25 to 30% cpu usage. Dream setup, flawless

I also enjoy 400 down and 40 up bandwidth from my internet provider

I now wish to build a new pc this time looking at the AMD threadripper with 32 core and 64 threads.
The PC will be similarily speced with the other components.

Will i see even better performance or will it be a case of diminishing returns?

I do not think intel's quick sync has ever been used since I do not think they are on the higher end cpus.


Also, at my remote location where I have half of my 30 cams, the internet provider now offers 1 gigabit up and down. Right now there I have 500 down and 35 up. Will the gigabit both ways help when viewing cameras remotely?

Also, when is BI 5 out? Any new killer features?

Thanks !


Thanks !

Hey. Nice rig. What does BI say its total bit rate and MP/s is? (at the bottom of the Blue Iris Status window, Cameras tab) I assume you aren't using "Limit decoding" on any of the cameras??

You are right, quick sync is not available on i9-9940.

You told us yourself it runs flawless so I don't know what you expect to gain from switching to a 32 core threadripper. Based on this PassMark Intel vs AMD CPU Benchmarks - High End all of the current threadrippers (even the 32 core 2990WX) are likely to do worse than what you already have. At the very least, I'd suggest waiting until benchmark results show a significant gain rather than a loss before "upgrading".

35 Mbps upload is already a lot more than you need for remote viewing. Blue Iris won't even let you set a bit rate limit higher than about 8 Mbps. Though you can turn off the bit rate limit and sometimes achieve a higher bit rate, this is definitely a case of diminishing returns.

Perhaps the biggest new feature in Blue Iris 5 is that you can use one Blue Iris console to remotely view and control another. I've looked into how this is done internally, and it does not seem to be significantly more bandwidth-intensive than running UI3 or a mobile app. So, again, I don't think you'd gain anything from gigabit upload.

Just because Blue Iris remote access won't benefit really from higher bandwidth doesn't mean you could not appreciate having gigabit in both directions. That much speed really opens doors for things like storing offsite backups of everything you've got.

Something doesn't add up here. If you have 30x 6MP cameras but your total video throughput is 720 MP/s, that tells us you have an average frame rate of only 4 FPS.

I would say 720 MP/s is also too low to explain 25 to 30% CPU usage, unless perhaps these are all doing H.265 (I have practically no experience judging CPU usage of H.265 decoding), or maybe you are not using direct to disk or something.

My i7-8700K system purrs along at ~20% CPU with a load of 19000 kB/s and 1000 MP/s if running in service mode with the GUI closed. Granted this is with the benefit of hardware acceleration, but your CPU should run circles around mine even without hardware acceleration because your CPU cost more than my entire BI machine.

On each Dahua camera's setup page I specify maximum frame rates and bit rates and best i interval. However, in BI I am not getting those rates. That is why I wondered if gigabit both ways would increase frame rate in BI

Here is a snapshot which can help half of these cams are remotely accessed and half where I am now
I forgot I still have some <6mp connected and a few 4k

OH. I misunderstood. If you are remotely streaming cams 24/7 to BI like that and not being ultra-conservative with the bit rates then they'll be performing like shit once you pass your ISP's upload limit of 35 Mbps ... which will be easily hit with that kind of load. This is probably what is happening.

Consider lowering the bit rates and using VBR (not CBR) in the cameras that go out over the internet 24/7. And also get that speed upgrade.

Your last screenshot there is full of signs that the streaming is breaking down on a lot of cams.
Gigabit up and down being ordered for remote location coming soon to Long island too.

That will be nice !
