Thunderbolt™ (previously called Light Peak) is a hardware interface that combines data, video, audio, and power in a single connection. Thunderbolt™ combines PCI Express (PCIe) and DisplayPort™ (DP) into one serial signal, and additionally provides DC power, all in one cable.
Thunderbolt™ 1 and Thunderbolt™ 2 use the same connector as miniDP (DisplayPort) to connect to peripherals, while Thunderbolt™ 3 uses a USB Type-C connector (Figure 1).

Thunderbolt™ 3 brings Thunderbolt™ technology to USB Type-C at speeds up to 40 Gbps, creating one compact port that does it all – delivering the fastest, most versatile connection to any dock, display or data device like an external hard drive. Thunderbolt™ 3 uses a USB Type-C connector/port to connect to supported peripherals.
Thunderbolt™ is currently available in Thunderbolt™, Thunderbolt™ 2 and Thunderbolt™ 3.
|Thunderbolt™||Thunderbolt™ 2||Thunderbolt™ 3|
|Up to 10Gbps||Up to 20Gbps||Up to 40Gbps|
Different types of Thunderbolt™ capable devices available are external hard drives, audio/video capture devices, displays and I/O hubs.
Thunderbolt™ uses a connector that fits the miniDP (DisplayPort™) port or connector.
Thunderbolt™ devices require Thunderbolt™ certified cables for optimal performance. Thunderbolt™ certified cables come in copper or optical cable variants. Look for the Thunderbolt™ logo on the connectors and ports.
Although the port's appearance is physically the same as miniDP (DisplayPort™), using standard miniDP (DisplayPort™) cables cannot be used to connect Thunderbolt™ devices.
The port's appearance is physically the same as miniDP (DisplayPort™). To confirm you have a Thunderbolt™ port on your computer, display, or cable check for the Thunderbolt™ symbol next to or above the port or connector.
Yes, Thunderbolt™ 3 uses USB Type-C port and it is fully compatible with USB devices and cables. However, you may require compatible adapters to connect USB Type-A or other USB connectors.
Thunderbolt™ 3 is a superset solution which includes USB 3.1 (10Gbps), and adds 40Gbps Thunderbolt™ and DisplayPort™ 1.2 from a single USB Type-C port.Back to Top
