Evidence
The ConnectX-9 is largely iterative from ConnectX-8, with the same 800G networking bandwidth and 48-lane PCIe6 switch capability. However, CX-9 now supports 800G Ethernet with 4x200G PAM4 SerDes, compared to CX-8 that only supported it on InfiniBand. For the Rubin platform, NVIDIA is doubling the number of NICs per GPU to achieve 2x scale-out bandwidth.

② Atomic Claim
在 Rubin platform 上，NVIDIA 將每顆 GPU 對應的 NIC 數量加倍，以達到 2 倍 scale-out bandwidth。
