DivX Encoding:

DivX is a very popular codec and many people convert video into DivX for distribution across the web or playback on a DivX certified DVD Player.  We used DivX 6.2.0 and used the included DivX encoder tool to encode our test video.  The video sample is a 2:01 second WMV file that we converted using the Home Theatre Profile.  This test doesn't use any fancy optimizations or adjustments.  This was a simple drag and drop conversion that didn't require any setup or tweaking.  This test shows raw performance on both machines.

Quicktime H.264 Encoding:

We used QuickTime Pro and fired up a similar test using a different video clip.  This clip is a short AVI clip that is 16,491KB and 1:19 long.  It was taken from a digital camera and then dropped into QuickTime Pro for a little high compression H.264 encoding.  This is a very bandwidth friendly format that uses a lot of CPU power to compress quickly.

File Compression & Extraction:

This test shows how well both CPU's handle file compression and extraction.  Our test file is a 74.4MB Zip file that contains 10,092 files and folders.  It is mostly HTML, XML and MySQL databases so there is a lot of compression possible as these files are basically text files.  When the archive is uncompressed it occupies 398MB.  The compression ratio is a little better than 5.3:1.

The second series of application tests showed similar results as the first set.  Video encoding is done much more efficiently on the Core 2 Duo compared to the Pentium D.  DivX encoding is done 95% faster on the E6600 and Quicktime H.264 encoding is done an amazing 105% faster!  All this extra performance when run 266MHz slower.  File compression and extraction is a little different however.  Here the Pentium D 805 compresses almost 60% slower, but when it comes to extracting an archive it narrows the gap to a mere 2 seconds - 6%.  This is probably due to hard drive write speed though as our archive contains over 10,000 files.
