Context Before

If Rubin Ultra NVL288 is deployed, each Rubin Ultra GPU will have a scale-up bandwidth of 14.4Tbit/s uni-di, requiring 144 DPs of cables to connect the NVLink 7 switches.

Evidence

72 DPs per GPU times 288 GPUs means a total of 20,736 additional DPs required to connect this larger world size domain.

Context After

This entails a lot of cables, so it is an upper bound of how much cable content could be used.

② Atomic Claim

每顆 GPU 72 DPs × 288 顆 GPU，代表較大 world-size domain 需要額外 20,736 DPs。
