Darren Yee, Tech Marketing Engineer Intel Software Solutions Group, and I shot a video demo of TMPGEnc 4.0 Xpress, a popular video encoder that was optimized for Quad-core and Intel Streaming SIMD Extensions 4 (Intel SSE4) instructions on the Penryn family of Intel processors at the Fall 2007 Intel Developer Forum. The demo in the video show how the same application encoding video on both a Core 2 Duo and a Wolfdale dual core processor in Penryn family. This optimized version resulted in an over 2X improvement over Core 2 Duo using the same application encoding the same video clip. The Core 2 Duo machine encoded the file in 1:06 seconds where the Penryn machine tool only 40 seconds. The primary instruction used in this software optimization was MPSADBW for optimized Sum absolute difference calculations, a common operation used in motion estimation.
