What this part means

the call it.

Its job in the formula

RnR_n is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.

Where the article explains it

Call it RnR_n : the FLOPs-per-second a GPU’s tensor cores can deliver, divided by the bytes-per-second its memory subsystem can supply.

The passage around this formula

Call it RnR_n : the FLOPs-per-second a GPU’s tensor cores can deliver, divided by the bytes-per-second its memory subsystem can supply. The unit that falls out is FLOPs per byte — the arithmetic intensity a workload needs in order to keep that generation’s compute fed rather than starved. This is not a new…
