For this test we used Cyberlink Power Producer in conjunction with DIVX 6.0Pro to encode "The Matrix" MPEG2 down to a MPEG-4 high resolution video file.
The Cyberlink software comes with its own time clock to indicate the time taken to encode the movie as well as average CPU usage and average FPS during the encode. We used DIVX 6.0 due to its support for Dual Core CPUs as well as Intel SSE3 and Hyper Threading.
Core Duo has managed to outperform the most impressive Multimedia Encoding CPU we have ever seen by quite a bit. It's good to see that the performance has lived up to expectation for the Core Duo and Multimedia tasks.
