Evidence
This has the advantage of using the same cold plate to cool both the CPUs, GPUs, and ConnectX-7/8 NICs.
Context After
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). This is an extremely fast connection and allows the CPUs to share resources and memory similar to the HGX H100/B100/B200 servers which have 2 CPUs and have NUMA (Non-Uniform Memory Access) regions.
② Atomic Claim
GB200 reference design 使用同一個 cold plate 同時冷卻 CPU、GPU 與 ConnectX-7/8 NIC。
