Cortex-A72 Maximum Theoretical Linpack Performance R_peak


As part of my MSc Scientific Computing at UCL, I'm benchmarking a small Raspberry Pi 4 Model B cluster.

I would like to reference the theoretical maximum performance of the BCM2711 (4 x ARM Cortex-A72) in Linpack terminology, R_peak.

I believe R_peak to be: 1.5 GHz x 3-way dispatch x 4 cores = 18 Gflops. This seems to be the "standard" Linpack methodology.

It would be very helpful if someone more knowledgable than me can confirm that this seems reasonable. Or even better, if there is some official ARM benchmarking material which I can reference in my dissertation?

Best wishes
