Context Before

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.

Evidence

However, it is plausible that Rubin Ultra NVL576 will be rolled out in test volumes before Feynman NVL1152, where we will see actual volume ramp of scale-up CPO.

Context After

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.

② Atomic Claim

合理的情境是：Rubin Ultra NVL576 先以 test volume 推出，之後到 Feynman NVL1152 才會看到 scale-up CPO 真正的 volume ramp。
