Media Encoding Tests
LAME 3.97a MT MP3 EncoderThis 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.
Windows Media Encoder x64
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
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.
Handbrake
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.
7-Zip Compression
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%.
i love this new techeal with
i love this new techeal with 6 core i7 6 core
i want 1 now
good luck 5 out of 5 stars from here
how many cores does a hexa
how many cores does a hexa core processer have
