SemiAnalysis’s May 26, 2026 Phase 4 architecture model gives roughly 87% utility-to-VRM; the guide’s stated AC fixture is roughly 82%.
~87% SST/800 VDC (analyst model) vs ~82% AC (guide fixture)modeled
| Value kind | modeled — Interpret this value according to its displayed kind, scope, source, and as-of date. |
|---|---|
| Scope | Analyst architecture model (SemiAnalysis Phase 4, May 26, 2026), not a measured facility or prototype acceptance result; distinct from Chapter 4.1’s assumed 0.98×0.965×0.92 guide fixture. The ~82% AC comparator is the guide’s representative four-stage fixture, whose high end (0.99×0.97×0.96×0.94 = 86.7%) coincides numerically with the modeled ~87% DC result — different chains, bases and evidence classes, not a tie. |
