Is USB 4 the same as Thunderbolt 3?

The world of technology is constantly evolving, and with it comes the introduction of new and improved standards for connectivity. In recent years, two prominent standards have emerged – USB 4 and Thunderbolt 3. While both aim to provide faster and more versatile connections, it leads us to ponder, are they the same? Let’s explore this question directly:

Is USB 4 the same as Thunderbolt 3?

No, USB 4 is not the same as Thunderbolt 3. However, they share many similarities and have certain compatibility features. To fully understand the distinction, it is important to delve into the details of each technology.

USB 4, the latest generation of the Universal Serial Bus standard, is designed to provide faster data transfer rates and increased power delivery capabilities. With speeds of up to 40 Gbps, it offers significant improvements over previous USB standards. USB 4 also incorporates support for alternate data modes, enabling the simultaneous transfer of different types of data.

On the other hand, Thunderbolt 3 is a connectivity standard developed by Intel in collaboration with Apple. It boasts even higher speeds, allowing for data transfer rates of up to 40 Gbps as well. In addition, Thunderbolt 3 supports power delivery, video output, and daisy-chaining multiple devices through a single USB-C port.

While USB 4 and Thunderbolt 3 may seem strikingly similar in terms of speed, the primary difference lies in their underlying technologies. Thunderbolt 3 IP was contributed by Intel to USB 4, enabling Thunderbolt 3 compatibility and leveraging USB-C connectors.

So, what does this mean for consumers?

The incorporation of the Thunderbolt 3 technology into USB 4 brings greater compatibility and flexibility for users. With USB 4 devices, you can connect Thunderbolt 3 peripherals seamlessly, expanding the possibilities and options available for a wide range of applications.
