① SA Source

Context Before

Source: SemiAnalysis

Unfortunately, between the L1 NVSwitch and the L2 NVSwitch, the distance is greater than what copper can achieve; thus, optical connections must be used. Furthermore, the L2 NVSwitches use Flyover cables to go to the OSFP cages on the front of the chassis. The additional BOM cost for NVL576 is astronomical at over $5.6 million dollars (9.7k per GPU) that Nvidia would need to pay to their suppliers.

Evidence

Applying a blanket 75% gross margin means customers would need to pay an additional 38.8k per GPU for NVL576 copper + optical connections.

② Atomic Claim

若假設 75% gross margin,SemiAnalysis 估計 NVL576 copper + optical connections 將增加約每 GPU 38.8k 美元的客戶成本。
