ExtremeTech is taking a close look at the two new video transcoding techniques from AMD and nVIDIA, ATI Stream and CUDA.  The software transcoder they will be using comes from Cyberlink, called MediaShow Espresso, a $40 product that supports both AMD and nVIDIA’s technology.  The transcodes that they will attempt are for the iPhone, MPEG2, Xbox and native H.264, and they use 3 movie trailers as the media.  This GPU technology certainly beats CPU encoding; but which one is the fastest?

Steve Grever has also published an indepth look at the capabilities of CUDA based applications, like transcoding, which you can read at the top of the page.
“At the end of last year, we took at look at video encoding performance on the CPU, Nvidia GPUs, and ATI GPUs. In that article, we couldn’t provide an apples-to-apples comparison. Simply put, there was no application to transcode video that supported Nvidia’s CUDA, ATI Stream, and was also well optimized for CPUs. Now, there is.”
