With Type-C’s Power Deliver 2.0 specification  allowing for chargers that can supply up to 100W of power, it will be  possible (though optional) to use Thunderbolt 3 to deliver that same  power, allowing for uses such as having a Thunderbolt dock or display  charge a laptop over the single Thunderbolt cable (the one thing Apple’s  Thunderbolt display can’t do today with Thunderbolt 2). That said, the  USB power delivery standard is distinct from Thunderbolt’s bus power  standard, so this doesn’t necessarily mean that all Thunderbolt hosts  can provide 100W of power, or even any USB charging power for that  matter. For standard bus-powered Thunderbolt devices, the Thunderbolt  connection will now carry 15W of power, up from 10W for Thunderbolt 2.  <a href="http://images.anandtech.com/doci/9331/TB13.png" target="_blank"><img src="http://images.anandtech.com/doci/9331/TB13_575px.png" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>  Finally, with the change in cabling, Intel is also clarifying how  Thunderbolt backwards compatibility will work. Thunderbolt 3 to  Thunderbolt adapters will be developed, which in turn will allow  Thunderbolt 1/2 and Thunderbolt 3 hosts and devices to interoperate, so  that older devices can work on newer hosts, and newer devices can work  on older hosts. Though we’re not clear at this time whether the adapter  is providing a simple bridge between the cable types (with the necessary  regeneration), or if there’s going to be a complete Alpine Ridge  controller in the adapter.  <a href="http://images.anandtech.com/doci/9331/TB22.png" target="_blank"><img src="http://images.anandtech.com/doci/9331/TB22_575px.png" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>  Wrapping things up, Intel tells us that they expect to see  Thunderbolt 3 products begin shipping by the end of the year, with a  larger volume of products in 2016. Given this timing we’re almost  certain to see Thunderbolt shipping alongside Skylake products, though  Intel is making it clear that at a technical level Skylake and  Thunderbolt 3 are not interconnected, and that it would be possible to  pair Alpine Ridge Thunderbolt 3 controllers with other devices, be it  Broadwell, Haswell-E, or other products.  As for whether Intel will see more success with Thunderbolt 3 than  the previous versions of Thunderbolt, this remains to be seen. The  switch to a Type-C port definitely makes it a bit easier for OEMs to  stomach – DisplayPort on laptops has been fairly rare outside of Apple –  so now OEMs can integrate Thunderbolt without having to install a port  they don’t see much value in. On the other hand this is still an  external controller of additional cost, which incurs power, space, and  cooling considerations, all of which would add to the cost of a  desktop/laptop as opposed to pure USB 3.1. As was the case with  Thunderbolt 1 and 2, Intel’s greatest argument in favor of the  technology is docking, as the use of PCI-Express and now the addition of  USB Power Delivery gives Thunderbolt a degree of flexibility and  performance that USB Type-C alone doesn’t match.  <a href="http://images.anandtech.com/doci/9331/TB15.png" target="_blank"><img src="http://images.anandtech.com/doci/9331/TB15_575px.png" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>  <a href="http://images.anandtech.com/doci/9331/TB17.png" target="_blank"><img src="http://images.anandtech.com/doci/9331/TB17_575px.png" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>Moving on, by building Thunderbolt 3 on top of USB Type-C, Intel is  also inheriting Type-C power delivery capabilities, which they will be  making ample use of.
