Context Before
Source: Nvidia VR NVL72 Component BoM and Power Budget Model ↗
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
CX-9 現在可透過 4×200G PAM4 SerDes 支援 800G Ethernet；相較之下，CX-8 的 800G 僅支援 InfiniBand。
