Probably. USB4 ports typically appear on laptops with AMD Ryzen processors inside. USB4 and Thunderbolt 4 are compatible and functionally equivalent. (Though Thunderbolt is an open standard, Intel declines to certify non-Intel hardware. That means that Ryzen laptops end up with USB4 ports, and Intel Core laptops include Thunderbolt.) USB4 is essentially a subset of Thunderbolt 4, mainly designed as an an I/O specification. As a subset of Thunderbolt 4, a USB4 device will run just fine plugged into a Thunderbolt 4 port. But dock makers tell us that a Thunderbolt 4 device may not work as expected when plugged into what is specifically a USB4 port. Instead, most hubs and docks are marketed as Thunderbolt 4, while most devices (like an external SSD) are designed around USB4. (We test Thunderbolt docks on Thunderbolt laptops.) There are USB4 docks, however, which you'll find in our list of best picks, which we've also tested. USB4 Version 2 is an upcoming standard that will propel USB4 to 80Gbps, just like Thunderbolt 5. The first products will debut (at a guess) in early 2024, but the USB-IO hasn't given us an exact timeline or the capabilities of USB4V2 docks. Note that Thunderbolt 3 and 4 require at least 15W to power devices plugged into the Thunderbolt port, such as a bus-powered hard drive. USB4 requires just half that.
