With IB (Quantum X800) you have 72x physical OSFP ports that can do 144 ports. Each electrical lane runs at 200G-PAM4, so it's 144x(4x200G-PAM4).

With the SN5600 for Ethernet (Spectrum-X), which is 64 physical ports, you're running each port at 8x100G-PAM4).

Is the Quantum X800 generally available now? Looks like it was announced in March. The SN5600 was released last year on the other end.
