USB 4
USB 4 is a high-speed connector standard finalized by the USB Implementers Forum in 2019. It builds upon USB-C technology and is based on Intel’s Thunderbolt 3 protocol, which Intel made available for licensing to other manufacturers. The standard represents a significant advancement in data transfer capabilities and power delivery compared to previous USB generations.
Technical Specifications
USB 4 supports data transfer speeds of up to 40 gigabits per second, which doubles the bandwidth of USB 3.2. The standard maintains backward compatibility with USB 3.2, USB 2.0, and Thunderbolt 3 devices when connected through appropriate adapters. USB 4 also supports enhanced power delivery, capable of delivering up to 240 watts through the same connector used for data transmission.
Adoption and Use
USB 4 has been integrated into various consumer devices including laptops, external storage solutions, and docking stations. Its compatibility with Thunderbolt 3 devices and previous USB standards has facilitated gradual industry adoption. The technology enables faster file transfers, improved video streaming capabilities, and more efficient charging for compatible devices.
