Вообщем я залез на сайт Thunderbolt FAQ ;)
What are the video formats supported by Thunderbolt 3? Thunderbolt 3 is based on the DisplayPort 1.2 specification and can support up to 2 streams (eight lanes) of DisplayPort 1.2 video bandwidth. A single cable now provides four times the data and twice the video bandwidth of any other cable, while also supplying up to 100W of power.
One 4K display (4096 x 2160) 30-bit @ 120 Hz
One 5K display (5120 x 2880) 30-bit @ 60 Hz
Two 4K displays each (4096 x 2160) 30-bit @ 60 Hz
Why is Thunderbolt the best USB-C for docking? Now, one compact port provides Thunderbolt 3 data transfer, support for two 4K 60 Hz displays, and quick notebook charging up to 100W with a single cable. Also, any Thunderbolt or USB dock can connect to a Thunderbolt 3 computer making it the most advanced and versatile USB-C docking port available.
Can I connect USB devices to a Thunderbolt 3 port? Yes,
Thunderbolt 3 ports are fully compatible with USB devices and cables.
Can I connect Display Port devices to a Thunderbolt 3 port? Yes,
Thunderbolt 3 ports are fully compatible with DisplayPort devices and cables.
Is Thunderbolt 3 backwards compatible with Thunderbolt and Thunderbolt 2? Yes,
solutions and products built to Thunderbolt and Thunderbolt 2 specifications will work with Thunderbolt 3 via an adapter.
Why did Thunderbolt 3 move to the USB-C connector? Thunderbolt 3 needed a new connector to achieve 40Gbps and fit into smaller form factor devices. With the USB-C connector allowing for alternate modes, it made sense to bring Thunderbolt to this connector and create a superset solution that supports both Thunderbolt and USB.
What is the difference between Thunderbolt 3 and USB-C? Thunderbolt 3 is a superset solution which includes USB 3.1 (10Gbps), and adds 40Gbps Thunderbolt and DisplayPort 1.2 from a single USB-C port. This enables any dock, display, or data device to connect to a Thunderbolt 3 port, fulfilling the promise of the USB-C connector.
