The short answer: Look at the laptop’s published specifications to be sure. A Thunderbolt port uses a USB-C connection, and it may look indistinguishable from a USB-C port. Put another way: All Thunderbolt ports are USB-C, but not all USB-C ports are Thunderbolt-equipped.Thunderbolt ports are supposed to have a small lightning-bolt icon to identify them. But some laptop makers use a similar lightning-bolt icon to indicate that a USB-C port can be used for charging your phone, and not for Thunderbolt. Laptop makers sometimes don't want to clutter the clean lines of their products by a
Put simply, 40Gbps, for Thunderbolt 3 or 4.Most USB-C ports are built on the second-generation USB 3.1 data-transfer standard, which transfers data at 10Gbps. Thunderbolt 3 and 4 ports, the most common standard, transfer data at up to 40Gbps. Thunderbolt 4 differs very slightly in that it supports a theoretical maximum of 32Gbps for external storage devices, but you probably won't notice the difference.Intel unveiled an 80Gbps version of Thunderbolt in 2024, called Thunderbolt 5, meaning that you'll see Thunderbolt docks with even more capabilities. In certain scenarios, Thunderbolt 5 can rero
What should I buy: Thunderbolt 3, Thunderbolt 4, or Thunderbolt 5?
It's not a bad idea to match your laptop's hardware specification to the dock: Thunderbolt 3 to Thunderbolt 3, Thunderbolt 4 to Thunderbolt 4, and so on. Thunderbolt 3 and 4 are basically the same, though retailers have almost entirely phased out their Thunderbolt 3 dock inventory.The default choice is a Thunderbolt 4 dock. You can always future-proof your setup with an 80Gbps Thunderbolt 5 laptop and dock. but those aren't essential quite yet. I would normally say that Thunderbolt 5 docks are backwards-compatible to Thunderbolt 4 and Thunderbolt 3 docks, but that doesn't seem always true. If
I already own a USB-C dongle. Can I use it with Thunderbolt?
Yes, you can connect the dongle to a Thunderbolt port. But the 10Gbps dongle won't magically transform into a 40Gbps Thunderbolt port, as there's circuitry within the dock that allows it to work with your laptop's high-speed Thunderbolt port. However, there's nothing saying that you can't connect the dongle to an available USB-C port on the Thunderbolt dock itself, either. If your laptop has two Thunderbolt ports, you can also attach a Thunderbolt dock to one port, and the dongle to the other.That solution will add more clutter to your desk, but it might allow you to buy a cheaper, budget dock
