Intel to Make Thunderbolt Royalty-Free; Looking to Increase Adoption

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.

AquinusSame cable and connector, yes but there are limitations. TB 1 and 2 had special circuitry in the connectors to mux/demux the PCI-E signal into something that can handle distance a little better. If you're using a passive TB3 cable (run of the mill Type C cable,) you're incredibly limited when it comes to distance unless you have an active cable, much like TB1 and 2.

So, there is a benefit in the sense that you can use cheaper and more basic cables but, your range is incredibly limited (< 1 meter @ 40Gbps) on a passive cable and if the quality is poor, it very well could still drop down to 20Gbps. The flexibility is nice but, it comes at a cost and like regular TB2 cables, you can't subtitute in active ThunderBolt cable for a Type C cable using USB, just as you can't use a ThunderBolt cable to drive Mini-DisplayPort.
obviously, the tech is still years a head of usb either way and better.

The Type C connector is actually pretty cool in the sense that it was designed to transfer more power and to support multiple kinds of transport over the same cable and connector. To me, that's really cool and is more universal than just USB 3.1 by itself. Honestly, the only reason this is possible is because of how similar USB 3.1, DisplayPort, HDMI, and ThunderBolt are as they're all built on differential signaling and to make them even more similar, they all use 4 differential pairs to do a lot of their magic.
