IBM PowerXCell Accelerator Board and T2/Linux

IBM 7046-B50

The IBM PXCAB (PowerXCell Accelerator) was more commonly known and sold as Fixstars GigaAccel 180 (GA-180) or Matrix Vision PXCAB PCIe Accelerat Board MVXCELL-8I. It features an revised variant of the Cell called the PowerXCell 8i, manufactured on a 65 nm process, 4 GB of DDR2 memory, as well as dramatically improving double-precision floating-point performance on the SPEs from a peak of about 12.8 GFLOPS to 102.4 GFLOPS total for eight SPEs.
