High Quality Content by WIKIPEDIA articles! The AMD FireStream is a stream processor produced by Advanced Micro Devices (AMD) to use the stream processing/GPGPU (General Purpose Graphics Processing Units) concept for heavy floating-point computations to target various industries, such as the High Performance Computing (HPC), scientific, and financial sectors. Originally developed by ATI Technologies until the company was acquired by AMD in 2006, the product line was previously branded as both ATI FireStream and AMD Stream Processor. The AMD FireStream can also be used as a floating-point co-processor for offloading CPU calculations, which is part of the Torrenza initiative.
