Because the LAME MP3 encoder is so heavily weighted for frequency, the Arrandale part is actually very competitive with the Core i7 part.


Windows Media Encoder x64

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

The Arrandale processor outshines the Core P8700 once again.


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.

Ditto.


Handbrake

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

Wow, this is a HUGE difference in notebook performance as the new Westmere part leaves the legacy CPU in the dust.


7-Zip Compression

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

The results in our 7-zip compression follow the same pattern we have seen all day…
