Evidence
However, optics for NVLink are coming
Context After
Moving back to the Kyber Rack, each Rubin Ultra logical GPU offers 14.4Tbit/s uni-di of scale-up bandwidth, using an 80DP connector (72 DPs used x 200Gbit/s bi-di channel = 14.4Tbit/s) per GPU for connectivity to the midplane board. Connecting all 144 GPUs in an all-to-all network will require 72 NVLink 7.0 Switch Chips running at 28.8Tbit/s uni-di of aggregate bandwidth each.
② Atomic Claim
不過，NVLink 的光學連線即將導入。
