Context Before

While the VR NVL72 system features GPUs and scale-up switches that are connected by copper cables, the VR HGX system features servers consisting of eight Rubin GPUs and four NVLink Switch chips.

Evidence

The second meaningful difference between the NVL72 and HGX deployments is that the former has a scale-out bandwidth of 1.6T per GPU

Context After

while the latter only has a scale-out bandwidth of 800G per GPU.

② Atomic Claim

NVL72 與 HGX deployments 的第二個重要差異，是前者每顆 GPU 的 scale-out bandwidth 為 1.6T……
