· 供应链分析
好问题！关于 $CRWV、$NBIS 和 $IREN，我尚未对 B300 集群进行物料清单(BOM)分析，但光网络(Optical Networking)资本支出占比可能在 10-20% 左右。 我记得做过测算，即使磷化铟(InP)价格上涨 30 倍，集群价格仅边际增加 3%，这对 Google 来说微不足道，仅对内部收益率(IRR)造成极微小的影响。 话虽如此，我不确定 InP 成本是仅边际增加，还是因总可寻址市场(TAM)极小且突然用于 AI 导致供应受限而上涨 50 倍。 总之，短中期影响甚微。长期我更担心超大规模云服务商(Hyperscaler)转向定制 ASIC 并将英伟达作为过渡期。 我们需要观察 Neoclouds 是否能在拥有极大杠杆的 2-3 年窗口期内，基本转变为超大规模云服务商。
Good question! As for $CRWV, $NBIS, and $IREN, I haven’t done a BOM on B300 clusters, but optical networking is probably around 10-20% of capex. I remember doing calculations and increasing InP prices by 30 times would only create a 3% marginal increase on cluster prices, which is extremely negligible to Google but hurts IRR just a tiny tiny bit. That being said I don’t know if InP costs just marginally increases or it goes up 50 times because it’s incredibly low TAM and suddenly it’s used for AI/supply constrained. So basically little effect short-medium term. Longer term I’d be more worried about hyperscaler shift to custom ASICs and using nvidia as a transition period. We’d need to see if Neoclouds can basically become hyperscalers themselves in the 2-3 year window where they have extreme leverage
