A8-7670K CPU Review

Video encoding

DivX

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 a .avi file, using the “HD 1080p” output profile. The results below are given in seconds, so the lower the better.

On DivX encoding, the A8-7670K was 17% slower than the Pentium G3460, but was on par with the Pentium G3220.

DVDShrink

DVDShrink is an old but still very useful program to “shrink” video DVDs that have more than 4.7 GiB of data to fit single-layer DVD media. We used it to compress the DVD of “The Lord of the Rings: The Fellowship of the Ring” DVD to 4.7 GiB. The results below are given in seconds, so the lower the better.

In this test, the A8-7670K was 22% faster than the Pentium G3460 and 32% faster than the Pentium G3220.

Media Espresso

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.

Here the A8-7670K was 30% slower than the Pentium G3460 and 19% slower than the Pentium G3220.
