Context Before

While the VR NVL72 system features GPUs and

Evidence

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.

Context After

The second meaningful difference between the NVL72 and HGX deployments is that the former has a scale-out bandwidth of 1.6T per GPU while the latter only has a scale-out bandwidth of 800G per GPU.

② Atomic Claim

……與透過 copper cables 連接的 scale-up switches；相較之下，VR HGX system 的 servers 由 8 顆 Rubin GPUs 與 4 顆 NVLink Switch chips 組成。
