And what are those numbers for fabric speed?..

  900GB/s (GByte) bidirectional.

    Oh, that's very impressive!

    Do you think they actually mean 900Gb/s (Gbit) here? 18 ports of todays ~50Gb/s serdes would give 900Gb/s. And that'd be twice the bandwidth of their Nvlink 2.0 stuff (~25Gb/s), which would seem a reasonable evolution. Edit: Turns out that a single Nvlink 3.0 port is 8-bits wide and since 144 50Gb/s serdes on a (big) chip is perfectly doable - 900GB/s must be correct.

      The article notes it's a 2B transistor switch chip... which boggles the mind.

      PCIe 3.0 x16 already is capable of more than 100gbps per port. 900gbits total bandwidth for 18 NVLink ports would be abysmally slow.
