What is the difference between Thunderbolt and USB-C?
Thunderbolt and USB-C are often confused with each other due to their physical similarities. However, they serve different purposes and have distinct capabilities. Thunderbolt is a hardware interface developed by Intel that allows for faster data transfer speeds, while USB-C is a type of connector that can be used for various purposes, including data transfer, power delivery, and display output.
In simpler terms, USB-C is a physical connector that can support multiple protocols, including Thunderbolt, USB, DisplayPort, and Power Delivery. On the other hand, Thunderbolt is a specific protocol that requires a Thunderbolt controller and a compatible device to function. This means that not all USB-C ports support Thunderbolt, and not all Thunderbolt ports are USB-C.
Can I use a Thunderbolt cable with a USB-C device?
If you have a Thunderbolt cable and a USB-C device, you might be wondering if you can use them together. The answer is yes, but with some limitations. A Thunderbolt cable can be used with a USB-C device, but it will only work at USB speeds, not Thunderbolt speeds. This is because the device itself does not support Thunderbolt, so the cable’s Thunderbolt capabilities are not utilized.
However, if you have a Thunderbolt device and a USB-C cable, it’s a different story. In this case, the device will only work at USB speeds, even if the cable is capable of supporting Thunderbolt speeds. This is because the cable does not have the necessary Thunderbolt controllers to support the faster speeds.
What are the benefits of using Thunderbolt over USB-C?
Thunderbolt offers several benefits over USB-C, including faster data transfer speeds, higher bandwidth, and the ability to daisy-chain multiple devices. Thunderbolt 3, for example, can transfer data at speeds of up to 40 Gbps, while USB-C typically tops out at 10 Gbps.
