Nominal Capacity vs. Deliverable Chips: The Gap in Every Forecast

Nominal capacity counts what lines can release. Deliverable chips count what customers receive. The 300,000-chip gap between them is where forecasts go wrong.

By Marco Wade · 3 November 2026 · 4 min read
Nominal capacity: the chip count a set of lines can release in a period if yields and wafer allocations hold, before competitors on shared lines and the packaging, memory and test stages take their cut.

The gap is where forecasts go wrong. Nominal capacity counts what a line can release; deliverable chips count what customers actually receive, after the other designers on the same lines take their share and after packaging, memory and test have finished taking theirs.

Why the two diverge

A line does not care which design it is printing. When a new part enters the queue it enters it against the incumbents, and who gets how many wafers is settled by negotiation and project priority as much as by price. A finished die without stacked memory is inventory, not a product. Both effects open a standing shortfall between the nominal count and the deliverable one.

The 2027 example

If yield improves on schedule, nominal capacity releases 3 to 3.5 million dies in 2027 — the number that gets quoted in February. Real deliveries land nearer 2.6 to 2.7 million in the neutral case, a shortfall of 300,000 to 500,000 chips. Anyone building a demand model on the nominal figure is building on the top of the bar rather than the bottom.

How to spot the nominal figure

It is the round number attributed to a product line without a delivery date attached, and it usually arrives first. The deliverable count follows months later in shipments, which is why the discipline is to treat every quoted capacity number as a ceiling case and to ask, before using it: which other designs share these lines, and what has to be true downstream for a started die to become a shipped one.

The full treatment, with the contracts and the interviews behind these numbers, runs in the letter.
