Encoding Performance using DivX 6.1, WME9, Quicktime (H.264) & iTunes
Although to a lesser degree than 3D rendering applications, encoding apps benefit very well from moving to more cores. DivX and Windows Media Encoder show a ~40%-55% improvement while QuickTime's H.264 encoding shows basically no benefit, and neither does MP3 encoding. There is certainly potential for either task to be further optimized for multi-core architectures, and hopefully we will see that in future versions of the software, but without proper programming support, even tasks that could potentially make great use of quad core processors will show little to no benefit.
