[SOLVED] What is the technical definitions of Thunderbolt 3? (Asking for super nerdy friend.)

[borkborkbork]

Is Thunderbolt defined purely by its hardware, such as "anything that is USB-C with 4 PCIE lanes"? Or is it defined as being able to transfer a minimum amount of data per second?

Thank you in advance.

I don't understand which features could be taken away and could still technically be Thunderbolt 3.

it need all to call thunderbolt 3. there is no optional feature

So it needs both 4 PCI lanes gen 3 and 8 lanes of displayport 1.2? Are they simultaneous or alternative requirements?

I guess I want an actual spec sheet and not that press release.

My port is x2. I'm pissed off. Where is the spec sheet that lets them justify them calling this Thunderbolt 3?

What port is x2? You may want to clarify why you are asking this a bit.

My friend responds: "I could be the ghost of Adolf Hitler asking on behalf of the bones of Genghis Khan. It's a technical question."

Apparently there are 3 different flavors of TB3 controllers, one of which is PCIe x2.
