Evidence
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. This means the new NVLink 6 Switch chip has the same 28.8T bandwidth as NVLink5 Switch, with half the number of ports 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. The layout remains the same as NVIDIA’s previous switches, with 2 sides for IO and a central logic section crossbar and 3.6 TFlop SHARP in-network compute acceleration.

② Atomic Claim
The NVLink 6 switch uses custom 400G bidirectional SerDes operating at twice the prior data rate.
