Datacenter Blackwell is Gen6, which is critical when pairing it with CX8 (2x400G) as otherwise you'd be stranding NIC BW.

please link me a B200 (not a B300) system with CX8 that uses gen6 x16 instead of gen5 x32.

to the best of my knowledge this does not exist, but I'd be happy to stand corrected.

(the official NVIDIA DGX B200 is gen5).
