Difference between Type-c and Thunderbolt 3
USB Type-c is an interface standard, and Thunderbolt 3 is a protocol standard, so you can see that the interface of the Thunderbolt 3 data cable is the same as that of the USB Type-c data cable.
Usually, the USB type-c interface follows the USB protocol, and has different bandwidths and speeds depending on the version of the USB protocol. In addition to the USB protocol, there are PD protocol, DP video transmission protocol, HDMI video transmission protocol, etc. The USB Type-c interface with power supply, video output and data transmission is generally called a full-featured USB Type-c interface.
To judge whether it is a full-featured USB Type-c interface, it mainly depends on whether the 24 pins are complete, while the full-featured USB Type-c cable depends on whether it has 24 cores.
At present, USB Type-c has been confirmed as a unified interface, and all future transmission protocols and devices will use USB Type-c interface.
Thunderbolt changed the physical interface of Thunderbolt 3 to USB Type-c in 2015, and the previous interface was mini DP.
From the appearance alone, there is no way to distinguish the various USB Type-c interfaces and Thunderbolt 3 interfaces, unless the notebook manufacturers strictly follow the USB-IF standard to mark them. Notebook manufacturers will not strictly follow the standards for labeling, they all like to hide their shortcomings. If the notebook manufacturer does not state that the USB Type-c interface supports video transmission and charging, generally only data can be transmitted.
The Thunderbolt 3 data cable and the full-featured USB Type-c data cable can be used in common, but the bandwidth of the USB Type-c data cable is smaller. The way to distinguish the data line is to see if there is a lightning mark on the interface.
Compared with USB Type-c and Thunderbolt 3, Thunderbolt 3 transmits data faster and supports higher output video resolution. Thunderbolt also has a PCIe bus, which can realize external PCIe devices.
