Apparently they have PCIe4 x16 and PCIe3 x32 models. Not sure if either of these exist at the moment but they so satisfy the PCIe bandwidth constraints.

They have one that is two PCIe3 x16 connections from one ASIC right now, it uses a ribbon cable :). That's janky, but it does work on currently available platforms. I've heard Mellanox will do a CAPI NIC, which is quite tantalizing.

Thanks, I didn't see that. But yes, that's weird. In regards to pcie4,I believe the power9 will be the first to have it, but I haven't seen a solid release date for that. Naples didn't look like it had it -- just more pcie3 lanes.
