ATI Stream Computing Support
With the release of ATI Catalyst 8.12 users can unlock the potential of accelerated
applications enabling ATI Stream technology for millions of ATI Radeon
graphics processors worldwide

AMD graphics processors to accelerate general purpose applications. These
capabilities will allow ATI Stream-enabled programs, for a variety of different
tasks and from a growing number of software vendors, to operate with optimized
performance or with new functionality.
ATI Stream Application: ATI AVIVO Video Converter
