Context Before

While the rack-level switching bandwidth has doubled, the number of NVLink Switch chips per rack has also doubled to 36, with each switch tray now housing 4 Switch chips.

Evidence

This means the new NVLink 6 Switch chip has the same 28.8T bandwidth as NVLink5 Switch, with half the number of ports

Context After

but running at double the rate using ‘400G’ bi-directional SerDes. This allows the high bandwidth switch design to remain as a single monolithic die, saving on design complexity.

② Atomic Claim

新的 NVLink 6 Switch chip 與 NVLink5 Switch 一樣具有 28.8T bandwidth，但 ports 數量只有一半。
