Choose a package only if its die crossing and heat path both close — stated inputs
Useful one-way payload 1.0 TB/s; transmitted-bit factor 1.10; combined PHY energy A 1.0 pJ/bit, B 3.0 pJ/bit; link allowance 20 W; buried-die power 600 W; path resistance 0.040 K/W; permitted rise 30 K.modeled
| Value kind | modeled — Interpret this value according to its displayed kind, scope, source, and as-of date. |
|---|---|
| Scope | Hypothetical package, combined PHY endpoints and top cold plate. Unsupported energy/thermal inputs and rationale are in the opening callout; Chapters 5.1 and 5.7 supply methods, not numeric bounds. |
| As of | 2026-09 |
| Source | UCIe Consortium specification catalogue — method reference; guide-authored hypothetical scenario September 8, 2026. No supplier quote or test measurement. |
| Derivation | Exact teaching assumptions chosen to expose the stated constraint and its reversal; not estimates of market prices or actual equipment. |
