Evidence
The current Blackwell NVL576 prototype “Polyphe” uses pluggable optics
Context After
We have shown a concept of NVL576 for GB200 previously ↗ with pluggable optics to interconnect the second layer of NVLink switches. The use of pluggables contributed to an enormous increase in BOM cost that made the system untenable from a TCO perspective for a switched all-to-all. However, it is plausible that Rubin Ultra NVL576 will be rolled out in test volumes before Feynman NVL 1,152, where we will see actual volume ramp of scale-up CPO.
The downstream implications of this are exposed in our institutional research, trusted by all major hyperscalers, semiconductor companies, and AI Labs, at sales@semianalysis.com
