Is USB-C Thunderbolt 4?

The USB-C port has become the standard interface for modern devices, providing a convenient and versatile connection for charging, data transfer, and display output. Alongside USB-C, we also have Thunderbolt, a high-speed technology developed by Intel. But are USB-C and Thunderbolt the same thing? Is USB-C Thunderbolt 4? Let’s dive into the details and find out.


USB-C and Thunderbolt are not the same, but they can coexist. In fact, **USB-C is a physical connector** that provides power and data transfer capabilities, whereas **Thunderbolt is a technology** that operates through the USB-C physical interface. Thunderbolt uses the USB-C port but adds higher data transfer speeds and additional features that USB-C alone does not offer.

When it comes to Thunderbolt versions, the latest iteration released by Intel is **Thunderbolt 4**. Thunderbolt 4 builds upon the capabilities of Thunderbolt 3 and provides even more functionalities and increased performance. However, it is essential to note that **not all USB-C ports support Thunderbolt 4**; there are USB-C ports that only support USB data transfer and charging without Thunderbolt capabilities.

So, what are the key differences and similarities between USB-C and Thunderbolt? Let’s explore some frequently asked questions to shed more light on this topic.

7. Is Thunderbolt 4 available on all laptops?

No, Thunderbolt 4 is not available on all laptops. It depends on the device manufacturer’s decision to include Thunderbolt 4 support. Some laptops may only have USB-C ports without Thunderbolt capabilities.

8. Can I charge my laptop using a Thunderbolt 4 port?

Yes, Thunderbolt 4 ports support power delivery, allowing you to charge your laptop and other devices using the same port.

9. Is Thunderbolt exclusive to Intel-based devices?

Initially, Thunderbolt was exclusive to Intel-based devices, but Intel has made it available for use by other manufacturers. As a result, Thunderbolt is now appearing on non-Intel platforms as well.

10. Are Thunderbolt 4 peripherals compatible with Thunderbolt 3 ports?

Yes, Thunderbolt 4 peripherals are compatible with Thunderbolt 3 ports. You can connect Thunderbolt 4 devices to Thunderbolt 3 ports and enjoy their functionalities, albeit limited to Thunderbolt 3’s capabilities.

11. Can I use a Thunderbolt 4 dock with a Thunderbolt 3 laptop?

Yes, you can use a Thunderbolt 4 dock with a Thunderbolt 3 laptop. However, make sure to check the compatibility and supported functionalities of the dock with your specific Thunderbolt 3 device.

12. Are there any devices that support both USB 4 and Thunderbolt 4?

Yes, USB 4 is designed to support Thunderbolt 4, which means there are devices available that incorporate both USB 4 and Thunderbolt 4 technologies. These devices provide a wider range of compatibility and enhanced performance.

In conclusion, USB-C and Thunderbolt 4 are not the same, but they work together to provide users with versatile connectivity options. Thunderbolt 4 is the latest iteration of the Thunderbolt technology and offers advanced features and higher performance. While not all USB-C ports support Thunderbolt 4, Thunderbolt 3 and USB-C devices can still connect and function, albeit at different levels of capability. Whether you’re looking to charge your device, transfer data, or connect to high-resolution displays, USB-C and Thunderbolt continue to evolve, providing enhanced experiences for users.
