Video encoding performance
We used the DivX converter, a tool included in the DivX package, in order to measure the encoding performance using this codec. The DivX codec is capable of recognizing and using all available cores and the SSE4 instruction set.
We converted a Full HD, six-minute long .mov video file into an .avi file, using the “HD 1080p” output profile. The results below are given in seconds, so the lower the better.
On DivX encoding, the Core i7-6950X was 12% faster than the Core i7-5960X.
Media Espresso is a video conversion program that uses the graphics processing unit of the video engine to speed up the conversion process. We converted a 1 GiB, 1920x1080i, 23,738 kbps, .mov video file to a smaller 320×200, H.264, .MP4 file for viewing on a smartphone. The results below are given in seconds, so the lower the better.
It is important to say that, with 10 cores enabled, MediaEspresso 6.7 refused to run on the Core i7-6950X. Then, we disabled two cores and the program ran perfectly, which makes us believe this version supports no more than 16 threads. So, the results were using “only” eight cores.
On this test, both processors performed the same way.
