now that usb3.1type-c has become the standard interface for motherboards and mobile terminals, some friends may wonder why my computer interface is both usb3.1type c and thunderbolt 3. iundefinedm sure a lot of friends have this question, so letundefineds talk about the relationship between usb3.1type c and lightning 3.
usb 3.1 is the latest transport specification based on usb, and the new usb 3.1 interface will double the bandwidth. up to 10gb pss, the coding rate is also increased again (and it is worth noting that the bandwidth of usb 3.1 gen 1 still remains the same as the 5gbps 3.1 gen 2 on usb 3.0, which is the original 10gbps usb 3.1).
usb type-c is exactly an interface standard. there are three kinds of interface standards in usb 3.1, namely usb type a, usb type b and usb type-c.
after the launch of usb type c, intel changed the physical interface of lightning 3 from mini dp to usb type-c based on the existing standard of usb 3.1 type-c. therefore, type-c is the attachment interface type of thunderbolt 3, both of which have the same shape, and lightning 3 is able to realize most of the functions of usb3.1 type c (if the type c power deliver 2.0 specification is supported by the by-pass, the whole function of type-c can be realized).
