Does My Laptop Have Thunderbolt 3?

The innovation of Thunderbolt is often said to be a result of the increasing mobility of the workforce, together with the decreasing size of devices within the tech sphere.

Thunderbolt is referred to as a data transfer technology that enables huge amounts of knowledge to be transferred fast and securely between two compatible devices, like a laptop and a monitor (to offer high-definition visuals to the monitor) or a camera and a laptop (to download large photo files from the camera). 

Thunderbolt 3 technology connects devices using a USB-C port. The Thunderbolt port’s USB-C interface is capable of transferring massive volumes of knowledge at rapid rates. 

The utilisation of one port type – USB-C, makes it easier to attach audio, video, USB and storage devices through one cable for a flexible, convenient solution. On one connection, Thunderbolt 3 delivers the fastest data and video bandwidth. It connects Thunderbolt devices, all HD and 4K displays, and billions of USB-C devices using one compact, reversible cable.

Is Thunderbolt 3 identical to USB-C? 

Although Thunderbolt 3 and USB-C look similar because they share identical ports, they’re not the same. Thunderbolt 3 is the technology that runs through the connectors and cables, while USB-C only refers to the look of connectors and cords. 

All Thunderbolt 3 devices employ the USB Type-C port, but not all Type-C connectors support Thunderbolt 3. This implies that some USB-C ports could also be unable to utilise Thunderbolt 3’s features. 

Basically, Thunderbolt 3 uses a USB-C connector, although not all Windows PCs with USB-C ports are Thunderbolt 3 compatible. 

This is often because the USB-C connector is also used for other protocols, including USB 3.1 and USB 2.0, so before connecting a UAD Thunderbolt device, you have to take care that your computer’s USB-C port supports Thunderbolt 3.

How do I know if my laptop has Thunderbolt 3? 

To know if your laptop has Thunderbolt 3: 

  • Check the documentation: If your laptop supports Thunderbolt 3, it will certainly be highlighted as a prominent feature within the handbook and on the manufacturer’s online product page for the laptop. A Thunderbolt logo is printed next to some USB-C ports to designate them as Thunderbolt 3 compatible. 
  • Check your USB-C port: Some USB ports have a Thunderbolt logo inscribed next to them to spot the ports as Thunderbolt 3 compatible.
