Mac mini, iMac Pro, and Macbook Pro all have two Thunderbolt 3 controllers.

The Mac Pro starts with two controllers but can be configured up to six.

The I/O is actually pretty good and provides for a ton of headroom for expansion down the line (I'm thinking primarily storage and GPU for my use-case).

I can see a pretty high powered eGPU saturating the lanes.
