Breaking down how USB4 goes where no USB standard has gone before

USB has come a long way since the 12Mbps days of the '90s. It has waved goodbye to USB-B and is inching away from USB-A in favor of the slim, reversible USB-C connector. Data transfer rates have increased so dramatically that we can run powerful setups with high-resolution monitors, speedy external storage, and numerous other devices from the USB Implementers Forum's latest open standard, USB4.
USB4 unifies the USB and Intel Thunderbolt protocols for the first time, expanding USB's capabilities while further dividing the technology into different performance classes. Adding features like dynamic bandwidth allocation ensures that USB4 is by far the most advanced USB generation. While there are PCs, docks, and cables supporting USB4, we've yet to see everything the protocol can do, like powering an eGPU without Intel branding.
