USB4 is a high-performance USB specification derived from Intel’s Thunderbolt 3 architecture that supports data transfer speeds of up to 40 Gbps. It enables dynamic allocation of bandwidth between data, display, and PCI Express traffic, improving efficiency for complex workloads. USB4 supports external GPUs, high-resolution displays, fast storage, and docking solutions, and requires the USB-C connector for all implementations while maintaining backward compatibility with earlier USB standards.
