  How sure are you of that? :) Everything I've seen says it's 2x 200GbE. One of many examples: https://www.storagereview.com/review/nvidia-dgx-spark-review-the-ai-appliance-bringing-datacenter-capabilities-to-desktops https://www.storagereview.com/review/nvidia-dgx-spark-review...

    That review says "Allows for a maximum of 200G bandwidth" between the two ports.

      It literally says this: > ConnectX-7 Smart NIC – 2x 200G QSFP and: > what makes this unit interesting is the dual 200 GbE QSFP56 interfaces driven by an integrated NVIDIA ConnectX-7 SmartNIC. --- Let's try a manufacturer's page then for confirmation: https://www.dell.com/en-us/shop/desktop-computers/dell-pro-max-with-gb10/spd/dell-pro-max-fcm1253-micro/xcto_fcm1253_usx#features_section https://www.dell.com/en-us/shop/desktop-computers/dell-pro-m... In the parts labelling diagram, it has this: > ConnectX-7 Smart NIC (2x 200G QSFP ... --- That being said, the Storage Review one does point out PCI-E bandwidth being a limiter anyway: > At first glance, you might deduce that the Spark allows for 400G of connectivity; unfortunately, due to PCIe limitations, the Spark is only able to provide 200G of connectivity.
