AMD Athlon XP 2800+ - Introducing the first 333MHz FSB Athlon XP

Media Encoding Performance

What was once reserved for "professional" use only has now become a task for many home PCs - media encoding. Today's media encoding requirements are more demanding than ever and are still some of the most intensive procedures you can run on your PC.

We'll start off with a "quick" conversion of a DVD rip (more specifically, Chapter 40 from the Star Wars Episode I DVD) to a DiVX MPEG-4 file. We used the latest DiVX codec (5.02) in conjunction with Xmpeg 4.5 to perform the encoding at 720 x 480.

We set the encoding speed to Fastest, disabled audio processing and left all of the remaining settings on their defaults. We recorded the last frame rate given during the encoding process as the progress bar hit 100%.

MPEG-4 encoding is a very bandwidth intensive procedure, which is why we see a healthy boost when moving to the 333MHz FSB Athlon XP 2800+; this is also part of the reason why the Pentium 4 does so very well in the test.

MP3 audio encoding is another great CPU test, although this sort of an application is much less platform intensive than the MPEG-4 test from above. Raw computational power is mostly stressed in the following MP3 encoding test; we encoded a 170MB wav file into a VBR (Variable Bit Rate) MP3 using the highest quality settings (-V 0) allowed by the LAME 3.91 MP3 encoder.
