with 5950X how many encoder instance can you open than and in time how long will it take
I primarily use Handbrake and do H.264 at quality settings 18.0 - 22.0 with Very Slow setting for best quality/smallest file size.
The time to process varies depending upon video length and content.
A 'typical' file will run my 10700K at 100% (single instance) and take 1.5 hours.
On my 3950X I run two instances and CPU utilization varies from 80% to 100% depending on the file content and how much compression is occurring.
In this scenario, I can process two 'typical' files in 1.25 hours - thus getting more than double the output of the 10700K.
I haven't tried three encodes but it would be a consideration if I found CPU usage falling into the 75%-80% range consistently.
I have 32 GB 3600/CL16 RAM and rarely hit 50% in use. No overclocking other than enabling DOCP.
