Media Encoding TestsLAME 3.97a MT MP3 Encoder
This version of the LAME MP3 encoder is multi-threaded and takes advantage of two threads.
Because of the dependence on a single thread for the majority of the work in our LAME MP3 encoding test the Core i7-980X performs pretty close to most of the competition.

WME is a great video encoding application that supports WMV9 HD codecs and more.
There isn’t a huge performance gain in our WMEx64 testing either though the new Core i7-980X does pull in the best result.
VirtualDub is a great application for just about any kind of video conversion but our testing we are using the DivX codec to shrink a collection of videos.
It would appear that our VirtualDub testing is limiting itself to somewhere around 8 threads as we don’t see notable changes in performance from the i7-975 to the i7-980X.
Known mainly for its DVD re-encoding prowess, our test uses the Handbrake command line interface.
Handbrake continues to scale very well with multi-core computing as we see an improvement of about 25% over the previous top speed.
I decided to replace the WinRAR test with a more repeatable and threaded application, 7-Zip.
Interestingly, with *only* 6GB of memory the benchmark wouldn’t run with 12 threads because of a lower than expected memory. Even so, in much the same way we saw the Blender results scale on the previous page, the 7zip results show that the 8 thread performance on the Core i7-980X is better than the 8 thread performance on the Core i7-975 for the same reasons. Performance lead: about 23%.
