Thunderbolt is one of the most flexible data delivery mechanisms ever developed: it boasts of both enormous versatility and performance. These connectors have seen increasingly higher adoption rates due to these characteristics, but are still to trickle down towards mid-range and entry-level offerings, which would be certainly some of the products to benefit the most, allowing them to substitute numerous, costly ports for a single jack-of-all-trades connection.

Intel is looking to solve this problem by removing royalties from Thunderbolt, further increasing adoption by integrating controllers within its own processors. The first Thunderbolt 3 "Alpine Ridge" chips, introduced in the third quarter of 2015, were manufacturer's only solution to implement Thunderbolt in their products; an extra chip which added costs and complexity to designs, which ended up limiting adoption to only higher-margin products. With Thunderbolt 3 an integrated part of the processors, those issues largely evaporate, with system builders being freed of having to design accommodations for an extra chip. Intel did not specify which processors would include the controllers or when they will ship, but the company says that it is going to make the Thunderbolt 3 specification available on a non-exclusive, royalty-free basis. Intel could have played towards eliminating the royalties on Thunderbolt 3 but only supporting it on its own processors, but the company has chosen not to do that: the door will be open for AMD and other companies to bake in support for the interface on their own solutions, spurring innovation and, more importantly, driving down costs of adoption.
