More updates will be coming soon.Īlthough it’s listed as a travel dock, the IOgear GTD300 serves as a very good regular work companion. We’ve updated our picks as of November 2021, adding the latest Plugable Thunderbolt dock to our tests. If you want to learn more about the benefits of a Thunderbolt dock, what to look for when buying one, or how to know whether your laptop will support one, look here as well. The longer answer, explaining the differences, may be found within our Thunderbolt buying guide below our recommendations. What’s the difference between Thunderbolt 3, Thunderbolt 4, and USB4? The simple answer is that they’re all similar. The bandwidth behind Thunderbolt 4 is enough to drive those displays and shuttle data back and forth between peripherals without causing your display to flicker or your video stream to stutter. Intel helped launch the updated Thunderbolt 4 specification in July 2020 as part of its 11th-gen “Tiger Lake” Core laptops, and the specification has become more popular on productivity laptops. If your laptop includes a Thunderbolt port, chances are it supports the Thunderbolt 3 or Thunderbolt 4 standard, both of which provide 40Gbps.
