Context Before

Aside from the X800-Q3400 air-cooled switch, NVIDIA will also offer a CPO version, the X800-Q3450, containing the same 144 ports of 800G.

Evidence

Each switch box consists of four 28.8T Quantum-3 Switch ASICs for a total of 115.2T per box switching capacity.

Context After

When used in conjunction with the VR NVL72 servers, the signal from the NIC at the leaf layer is split four ways—200G each way—to each switch ASIC within the box.

② Atomic Claim

每個 switch box 包含 4 顆 28.8T Quantum-3 Switch ASICs，每 box 總 switching capacity 為 115.2T。
