Context Before

Evidence

The ConnectX-9 is largely iterative from ConnectX-8, with the same 800G networking bandwidth and 48-lane PCIe6 switch capability.

Context After

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

ConnectX-9 大致是 ConnectX-8 的 iterative update，維持相同 800G networking bandwidth 與 48-lane PCIe6 switch capability。

• Epistemic Mode: ASSERTED
