Thunderbolt 3
Thunderbolt 3, introduced by Intel in 2015, is a high-speed hardware interface standard that merges the capabilities of Thunderbolt 2 and USB Type-C. It provides data transfer rates of up to 40 Gbps, making it one of the fastest connectivity technologies for consumer and professional devices. Thunderbolt 3 supports multiple protocols, including USB, DisplayPort, and PCI Express, allowing a single cable to handle data transfer, video output, and power delivery. This versatility has made it a popular choice for applications requiring high bandwidth, such as external GPUs, ultra-HD displays, and fast external storage solutions.

A key feature of Thunderbolt 3 is its integration with the USB Type-C connector, which offers a reversible design and simplifies device connectivity. It supports dual 4K displays at 60Hz or a single 5K display, making it ideal for high-resolution video editing and gaming setups. Additionally, Thunderbolt 3 allows for daisy-chaining of up to six devices, enabling users to expand their systems without cluttering their workspaces. Its ability to deliver up to 100W of power through the USB Power Delivery protocol further enhances its functionality.
Thunderbolt 3 has been widely adopted in premium laptops, desktops, and peripherals, including products from companies like Apple and Dell. It is backward compatible with earlier Thunderbolt versions and supports adapters for other interfaces, ensuring seamless integration with existing systems. Thunderbolt 3 also serves as the foundation for newer standards like USB4, which incorporates its features, ensuring the continuity and evolution of high-speed connectivity in the modern computing landscape.
