What is Thunderbolt 4 and how does it differ from previous versions?
Thunderbolt 4 is the latest generation of the Thunderbolt interface, offering faster speeds and improved performance. It was introduced in 2020 and is designed to provide a more comprehensive and user-friendly experience. Thunderbolt 4 builds upon the capabilities of its predecessors, Thunderbolt 3, by increasing the minimum required specifications for certification.
One of the key differences between Thunderbolt 4 and previous versions is the mandatory inclusion of certain features, such as dual 4K display support or a single 8K display, and the ability to supply up to 100W of power. This ensures that all Thunderbolt 4 devices meet a certain standard, providing users with a more consistent experience.
What is Thunderbolt USB4, and how does it relate to Thunderbolt 4?
Thunderbolt USB4 is a variant of the USB4 standard that incorporates Thunderbolt technology. It offers the same speeds as Thunderbolt 4 but with some differences in features and compatibility. Thunderbolt USB4 is designed to provide a more affordable alternative to Thunderbolt 4 while still offering high-speed connectivity.
The main difference between Thunderbolt USB4 and Thunderbolt 4 is the certification process and the level of performance. Thunderbolt 4 devices must meet stricter requirements, such as the ability to supply up to 100W of power, whereas Thunderbolt USB4 devices may not offer the same level of performance. However, both standards offer fast speeds and can be used for data transfer, display connectivity, and power delivery.
What are the key features of Thunderbolt 4?
Thunderbolt 4 offers several key features that make it an attractive option for users who require high-speed connectivity.
