The difference between Thunderbolt 3 interface and type-c
Intel released Light Peak technology and named it "Thunderbolt" and "Thunderbolt" interface, commonly known as "Thunderbolt interface".
Thunderbolt connection technology combines PCIExpress data transmission technology and DisplayPort display technology, which can transmit data and video signals at the same time. Each channel provides two-way 10 Gbps bandwidth, and the latest Thunderbolt 3 reaches 40 Gbps.
USB Type-C, also known as USB-C, is a hardware interface form of the Universal Serial Bus. The biggest feature of its appearance is that the upper and lower ends are the same. Compared with Micro-USB, users do not need to distinguish between the positive and negative sides of USB.
USB Type-C specification 1.0 was released by the USB Developers Forum (USB-IF) and completed in August 2014. It is roughly the same as the USB3.1 specification.
However, USB-C is just an interface and does not necessarily support USB 3.1 or Power Delivery. Since the USB-C specification was released in 2014, many new 3C devices, such as Android mobile devices, laptops, desktops and even game consoles, have begun to use this connection port. Windows 10 supports type-C natively.
What is the relationship between Thunderbolt 3 and Type C interface?
Type C belongs to the interface specification. Thunderbolt 3 belongs to the physical layer and uses the Type C interface. It is a specification standard and does not conflict with Type C. If you need to compare, you should compare it with the USB 3.1/3.2 interface, because in Intel's leadership and research and development process, The bandwidth of Thunderbolt can reach 40Gbps, which is 4 times the gap of USB3.1 10Gbps. In the past, due to interface limitations, it was not widely used in the market. However, since the beginning of Thunderbolt 3, Intel has based the interface specification on the Type C physical layer, which can fully realize most of the functions of USB Type C, with higher transmission rate and richer achievable content.
Therefore, the interface specification adopted by Thunderbolt 3 is Type C, so it also supports USB 3.1; however, Type C interface devices that support USB 3.1 may not necessarily support the Thunderbolt standard interface. Currently, all interfaces that support Thunderbolt 3 have a lightning "lightning" logo next to them for easy identification.
