Thunderbolt 5 can do bi-directional 80 Gbps....and Mac Studio Ultra has 6 ports...

That's still not even competitive with 100G Ethernet on a per-port basis. An overall bandwidth of 480 Gbps pales in comparison with, for example, the 3200 Gbps you get with a P5 instance on EC2.

To add to this GPU servers like supermicro have a 400GBe port per GPU plus more for the CPU.

Cost competitive though?

A 3 year reservation of a P5 is over a million dollars though? Not sure how that's comparable....
