Where the article explains it
If is the (roughly fixed, application-set) power envelope in watts and is the achieved energy efficiency of the best available accelerator at time t , measured in tera-operations per second per watt, then the usable on-device compute throughput is approximately .
The passage around this formula
itself is not free to grow indefinitely inside conventional CMOS. Horowitz, Alon, and Patil’s widely cited analysis of chip power scaling made the mechanism explicit: as feature size shrank across recent nodes, supply voltage and threshold voltage stopped scaling down at the historical rate, because pushing them lower drives subthreshold leakage up sharply, and power — not transistor count — became the binding limiter on how fast or how densely a chip could usefully run [ 11 ] . That single fact is the quiet premise behind most edge-AI marketing that promises “10x more efficient” silicon every generation: within one switching technology, each further gain in gets structurally…

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
