Context Before
Source: SemiAnalysis
This has the advantage of using the same cold plate to cool both the CPUs, GPUs, and ConnectX-7/8 NICs. The electrical lanes are routed to the OSFP cages at the front of the chassis with DensiLink connectors from the mezzanine board. This is similar to how Nvidia used DensiLink on their gold plated DGX H100 chassis to route from the ConnectX-7 to the OSFP cages.
Evidence
Similar to the Dual GH200, within the same compute tray, there is a high speed Coherent NVLink connection that operates up to 600GB/s bidirectional bandwidth (300GB/s unidirectional).

② Atomic Claim
同一個 compute tray 內的 coherent NVLink 連線最高提供 600GB/s 雙向頻寬（300GB/s 單向）。
