What the article says around this equation
None of this is visible from a peak-TOPS spec sheet, which is precisely why an independent, standardized benchmark matters for edge parts in a way it matters less for datacenter accelerators, where a workload can usually be resized to fit whatever hardware is available. MLPerf Tiny, built by a coalition of more than fifty organizations, measures accuracy, latency, and energy together on four small, representative tasks — keyword spotting, visual wake words, image classification on tens of kilobytes of model, and anomaly detection — specifically because a part’s peak efficiency number and its efficiency on a real, sub-milliwatt-class workload can diverge substantially once memory movement,…

None of this is visible from a peak-TOPS spec sheet, which is precisely why an independent, standardized benchmark matters for edge parts in a way it matters less for datacenter accelerators, where a workload can usually be resized to fit whatever hardware is available. MLPerf Tiny, built by a coalition of more than fifty organizations, measures accuracy, latency, and energy together on four small, representative tasks — keyword spotting, visual wake words, image classification on tens of kilobytes of model, and anomaly detection — specifically because a part’s peak efficiency number and its efficiency on a real, sub-milliwatt-class workload can diverge substantially once memory movement, quantization loss, and duty-cycling are accounted for [ 2 ] . Any claim about on-device capability growth that does not distinguish peak from measured, workload-level should be read with that gap in mind.
