This white paper demonstrates how to calculate and compare the peak floating-point performance of digital signal processors, GPUs, and FPGAs. Learn how Altera can reliably claim up to 1.5 TeraFLOPs of performance in Arria 10 devices and 10 TeraFLOPs in Stratix 10 devices using an industry-standard method. This paper also examines a real-life performance claim by Xilinx, showing how using a non-standard benchmarking method can make an FPGA appear to have higher performance.
