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…
