Media Encoding Tests

LAME 3.97a MT MP3 Encoder


This version of the LAME MP3 encoder is multi-threaded and takes advantage of two threads.

The Core i7-3960X is the new fastest CPU in this test, but doesn’t beat out the Core i7-2600K by much.



Windows Media Encoder x64


WME is a great video encoding application that supports WMV9 HD codecs and more.

The new SNB-E processor is about 10% faster than the Core i7-990X and is 16% faster than the Core i7-2600K.



VirtualDub


VirtualDub is a great application for just about any kind of video conversion but in our testing we are using the DivX codec to shrink a collection of videos.

Interestingly, VirtualDub doesn’t show a big gain for the 6-core processor compared to the quad-core Sandy Bridge.



Handbrake


Known mainly for its DVD re-encoding prowess, our test uses the Handbrake command line interface.

Handbrake makes good use of the extra cores on the Core i7-3960X and as a result shows a 25% advantage over the 2600K and 10% over the 990X.



7-Zip Compression


I decided to replace the WinRAR test with a more repeatable and threaded application, 7-Zip.

The 7Zip compression test shows good performance for the Core i7-3960X yet again, though it doesn’t really move past the Core i7-2600K until after 4 threads.
