Thunderbolt interface

Thunderbolt 3 was a game changer for the Thunderbolt interface.

With Thunderbolt 3 and the introduction of a USB-C compatible connector, any computer user could use just one computer port to attain 40Gbps data throughput, fast charging, connection to DisplayPort monitors, PCIe plus maintain all their existing USB-C peripherals.

Thunderbolt 3 allowed for daisy chaining of up to 6 Thunderbolt devices on a single port. The same port could also connect to a Thunderbolt hub or docking station that could connect even more devices and peripherals, with just a single cable back to the host computer.

Here's how Thunderbolt 3 is different from its predecessors -

  • The Mini DisplayPort connection type was changed to a USB-C type connection
  • All Thunderbolt 3 cables will work as USB-C cables
  • Not all USB-C cables will work as Thunderbolt 3 cables
  • Thunderbolt 3 has a top data transfer speed of 40Gbps as long as the cable is ≤0.5m
  • For longer cables, Thunderbolt 3 supports passive mode cables (cheaper) that have a top speed of 20Gbps, and active mode cables (more expensive) that retain the 40Gbps speed
  • Thunderbolt 3 is backwardly compatible with earlier versions of Thunderbolt, but due to the new port type, adapters are required to use legacy Thunderbolt devices
  • Any USB-C device plugged into a Thunderbolt 3 port will function normally.
  • Thunderbolt devices use discrete Thunderbolt chips to function, and as such they will not function if plugged into a USB-C port

Then in 2020, the further evolved Thunderbolt 4 was released.
