Equation 25 · Part 1 · What an AI Accelerator Actually Is: Silicon, Packaging, and the Memory It Can Reach
Symbol I
What this part means
the binding term.
Its job in the formula
I 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
Bandwidth-limited throughput is the regime where achieved FLOPS is irrelevant because I is the binding term.
The passage around this formula
a floor set entirely by memory traffic, in which peak arithmetic does not appear. This is why batching improves throughput so dramatically — the same weight bytes are amortised across many sequences, raising I — and why it does not improve single-stream latency at all.

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.
