Context Before

Each VR NVL72 Switch tray contains four NVLink 6 Switch ASICs and one system management module. The design of the Rubin NVLink 6 Switch tray is also simpler and

Evidence

relatively seamless compared to the first Oberon NVLink 5 Switch released for GB200 because Rubin NVLink 6 Switch trays will not use flyover cables.

Context After

As such, all NVLink signals will run over the PCB.

② Atomic Claim

……相較為 GB200 發布的第一代 Oberon NVLink 5 Switch，整體更順暢；原因是 Rubin NVLink 6 Switch trays 不會使用 flyover cables。
