Equation 1 · Part 7 · How Chiplets and Advanced Packaging Actually Work

Denominator: bump pitch

link bandwidth≈Nlanes×data rate per lane×module widthbump pitch\text{link bandwidth} \approx N_{\text{lanes}} \times \text{data rate per lane} \times \frac{\text{module width}}{\text{bump pitch}}

What this part means

The complete quantity below the fraction bar; it must be nonzero for this division.

Its job in the formula

bump pitch occurs below the fraction bar. The quantity above the bar is divided by this expression; zero is excluded as a denominator.

The passage around this formula

It is worth being explicit about what this standard does and does not guarantee. UCIe compliance means two chiplets can establish a working electrical link and exchange PCIe- or CXL-framed traffic across it — it is an interoperability floor, not a performance ceiling, and not a guarantee that any two arbitrary UCIe-compliant chiplets will perform well together. A retimer mechanism exists in the specification specifically to extend UCIe connectivity beyond a single package using off-package electrical or optical links, with each retimer implementing a full UCIe interface on its own local side and independently negotiated buffer credits — a detail that matters because it signals the standard’s…
