Performance during Audio and Video Encoding

In applications dealing with audio and video encoding, Pentium 4 processors have always been faster than their competitors from AMD. Pentium 4 670 with the highest clock rate and largest L2 cache appears the leader among Intel’s single-core solutions. In fact, only dual-core CPUs can compete with Pentium 4 670 in this type of tasks, though this competition is not always a success for the latter. Some codecs, such as Mainconcept and XviD, for instance, are still running faster on single-core processors.
