On the networking side. M4 max does have thunderbolt 5, 80gbps advertised. Would ip over TB not allow for significantly faster interconnects when clustering Macs?

Yes, people use Thundebolt networking to build Mac AI clusters. The Spark has 200G Ethernet that is even faster though.

Made the correction to 80Gb/sec thank you.

W.r.t ip, the fastest I’m aware of is 25Gb/s via TB5 adapters like from Sonnet.

You should not be using an adapter to get IP over Thunderbolt. Just connect a Thunderbolt5 cable to both machines.

For point to point sure, but if you want to connect multiple machines in an actual fabric you’ll need some kind of network interop.

The Asus clustering speed is not limited to p2p.

Fair enough. On the other hand you have more thunderbolts to make up a clique mesh of seven point to point Macs.
