Re: Apple using AMD cpu.

Apple can’t until either: Intel opensources thunderbolt or Apple drops Thunderbolt support.

Years ago Intel said they would but they still haven’t yet.

Edit: I originally stated Lightning and meant to say Thunderbolt.

There are a handful of AMD systems with Thunderbolt already. Presumably the situation will be better with USB 4.0.

They did and It is called USB 4. Where the top USB 4 profile provides full TB3 compatibility.

Intel has made Thunderbolt royalty free.

It may be royalty free but getting access to the chips and reference designs still requires signing an NDA with Intel (which they may or may not even give you a chance to do). They are still the gatekeepers for the technology because no one else makes comparable chips.

It’s still not royalty free yet.

There’s AMD mobo with thunderbolt support but they aren’t certified.
