 Originally developed by ATI Technologies around the Radeon X1900 XTX 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.The FireStream line has been discontinued since 2012, when GPGPU workloads were entirely folded into the AMD FirePro line.
