About Intel Thunderbolt Software:

Thunderbolt 3 was developed by Intel and uses USB Type-C connectors.Compared to Thunderbolt 2, Intel's Thunderbolt 3 controller (codenamed Alpine Ridge) doubles the bandwidth to 40 Gbit/s (5 GB/s), halves power consumption, and simultaneously drives two external 4K displays at 60 Hz (or a single external 4K display at 120 Hz, or a 5K display at 60 Hz when using Apple's implementation for the late 2016 MacBook Pros) instead of just the single display previous controllers can drive. The new controller supports PCIe 3.0 and other protocols, including HDMI 2.0, and DisplayPort 1.2 (allowing for 4K resolutions at 60 Hz). By virtue of being an Alternate Mode of USB Type-C, Thunderbolt 3 ports implement USB Power Delivery, allowing the ports to source or sink up to 100 watts of power, which allows companies to eliminate the separate power cable from some devices. Thunderbolt 3 allows backwards compatibility with the first two versions by the use of adapters or transitional cables.
