Fast data transfer of up to 20 Gbps from a single connection, twice that of previous Thunderbolt 2. Combined with PCI Express Gen 3 and DisplayPort 1.2, the application list is extensive. An example would be using an external GPU dock for your notebook, providing high-end gaming graphics from a lightweight portable computer. Thunderbolt 3 technology allows the use of two external displays up to 4K 60Hz each while also simultaneously providing other features like high-speed data and power. By incorporating technology based on USB Power Delivery, this allows Thunderbolt cables to provide up to 60W of power over the single connection. Legacy devices can also take advantage of up to 15W of power. The cable uses a fully reversible connector for quick attachment to your device. The Thunderbolt host port uses an integrated USB 3.1 controller for maximum backward compatibility at 10 Gbps speeds.
