200 Gbps Oh wow, that’s pretty bad.

  That's 200Gbps from that card to any other point in the other 9,408 nodes in the system. Including file storage. Within the node, bandwidth between the GPUs is considerably higher. There's an architecture diagram at <https://docs.olcf.ornl.gov/systems/frontier_user_guide.html https://docs.olcf.ornl.gov/systems/frontier_user_guide.html> that helps show the topology.

    I see, OK, I misinterpreted it as per node bandwidth. Yes, this makes more sense, and is probably fast enough for most workloads.
