Bytes per FLOP (B/F) is a measurement of memory intensity per compute work or the amount of bytes required to be transferred between the execution unit and the off-chip memory relative to the number of floating-point operations required for a particular task. B/F is a common figure of merit in the HPC community used to analyze the peak performance of a system under memory-bound workloads.
