Performance in Audio and Video Content Encoding Applications

Since NetBurst architecture is very efficient for streaming data processing, Pentium 4 processors feel at home in audio and video content encoding applications. However, Prescott puzzled us here: Pentium 4 processors on the new core somehow fall far behind their predecessors on Northwood core everywhere except data encoding with DivX codec. So, I believe that the new SSE3 instructions, which should soon appear in video and audio codecs, will only help Prescott to catch up with their Northwood based fellows, but will hardly provide them with any advantage in this type of tasks.
