FAQ
How do I do know if my laptop computer has Thunderbolt?
The quick reply: Take a look at the laptop computer’s revealed specs to make certain. A Thunderbolt port might look indistinguishable from a USB-C port, since they each use the identical bodily USB-C connection. Put one other means, all Thunderbolt ports are USB-C, however not all USB-C ports are Thunderbolt-equipped.
Thunderbolt ports are supposed to have a small lightning-bolt icon to establish them. However some laptop computer makers use an analogous lightning-bolt icon to point {that a} USB-C port can be utilized for charging your telephone, and not for Thunderbolt. Laptop computer makers generally don’t wish to muddle the clear strains of their merchandise by including further logos, it appears.
Including to the confusion, you might also see USB-C hubs marketed as “Thunderbolt suitable.” That’s true. You possibly can plug a Thunderbolt dock right into a non-Thunderbolt, generic USB-C port. However it will likely be restricted by the obtainable bandwidth that the port offers, so it’s considerably misleading in that regard.
Two laptops, each with USB-C ports, and each with lightning-bolt symbols. Which laptop computer affords Thunderbolt? The highest one, although it may be tough to inform. Consulting the producer’s specs is your most secure guess.
IDG
I already personal a USB-C dongle. Can I exploit it with Thunderbolt?
A USB-C dongle received’t change a Thunderbolt dock, as there’s circuitry inside the dock that enables it to work your laptop computer’s high-speed Thunderbolt port. Nonetheless, there’s nothing saying that you may’t join the dongle to an obtainable USB-C port on the Thunderbolt dock itself so as to add much more ports.
That answer will add extra muddle to your desk, however it would possibly help you purchase a less expensive, funds dock, too. It’s as much as you!
How briskly is Thunderbolt?
40Gbps, principally.
Most USB-C ports are constructed on the second-generation USB 3.1 data-transfer customary, which transfers information at 10Gbps. Thunderbolt 3 and 4 ports, the commonest customary, switch information at as much as 40Gbps. Thunderbolt 4 differs very barely in that it helps a theoretical most of 32Gbps for exterior storage units, however you in all probability received’t discover the distinction.
There are very uncommon exceptions: A brand new USB 3.2 Gen 2×2 spec can pair two 10Gbps channels collectively, creating an combination 20Gbps hub. And whereas the overwhelming majority of Thunderbolt 3-equipped laptops are designed with 4 PCIe lanes for a complete of 40Gbps, some laptops solely ship with two PCIe lanes for a complete of 20Gbps. (A Dell support page, for instance, particulars its four-lane and two-lane laptops.) Basically, a 20Gbps connection must be sufficient for a single 4K monitor operating at 60Hz, with a bit of additional bandwidth for different information transfers amongst linked peripherals.
In the true world, issues are barely extra difficult. Basically, Intel’s Tenth-gen and Eleventh-gen Core chips launched within the early days of Thunderbolt, and firm representatives say that you may depend upon them for 32Gbps of information, not a full 40 Gbps. Intel’s Twelfth-gen and Thirteenth-gen Core chips provide essentially the most constant Thunderbolt expertise, with 40Mbps Thunderbolt 4 speeds, together with 32Gbps for information transfers to and from storage units.
Our subsequent query describes the distinction between Thunderbolt 3, 4, and USB4.
What’s the distinction between Thunderbolt 3, Thunderbolt 4, and USB4?
The quick reply: Not that a lot, and we think about Thunderbolt 3 docks and Thunderbolt 4 docks to be functionally equal for many customers. The longer reply, which we’ll describe under, is that there are variations, and parsing the nuances will be complicated. Consider Thunderbolt 4 because the extra restrictive model of Thunderbolt 3, with little room for any gotchas.
Basically, Thunderbolt 3 and Thunderbolt 4 enable as much as 40Gbps most bandwidth, sufficient for 2 4K/60 shows. “As much as” is the important thing phrase: Thunderbolt 3 is just required to help a 10Gbps connection, permitting for a single exterior 4K show (a 16Gbps PCIe connection, paired with USB 3.2). Most producers transcend this, nevertheless, and our beneficial docks help the total specification (and two 4K shows) until famous. Thunderbolt 3 additionally helps a slower (16Gbps) PCIe connection for connecting to exterior storage.
Thunderbolt 3 can be the one specification (not Thunderbolt 4) that we’ve seen connecting to exterior GPUs, in case you’d prefer to strive that strategy.
Thunderbolt 4 doesn’t enable for any leeway—you’re getting a full-fledged 40Gbps connection (32Gbps PCIe + USB 3.2), no questions requested. For exterior storage, Thunderbolt 4 helps 32Gbps of information switch—this actually solely issues for video, exterior GPU connections, or presumably video games. Thunderbolt 4 helps “wake on sleep” from an exterior keyboard or mouse, which lets you faucet your exterior keyboard or wiggle your mouse to get up your PC, which is useful. Thunderbolt 4 permits for longer cables and extra Thunderbolt ports on laptops, too.
USB4 is actually a subset of Thunderbolt 4, primarily designed as an an I/O specification. You’ll most frequently see USB4 seem on AMD laptops, and Thunderbolt on Intel laptops.
USB4 can solely help one show, and producers can select whether or not it helps a 20Gbps connection or a 40Gbps connection, based on Thunderbolt dock designer Plugable. As a subset of Thunderbolt 4, a USB4 machine will run simply superb plugged right into a Thunderbolt 4 port. However a Thunderbolt 4 machine might not work as anticipated when plugged into what’s particularly a USB4 port. Don’t fear about this an excessive amount of, because it’s uncommon to see a USB4 hub. As an alternative, most hubs and docks are marketed as Thunderbolt 4, whereas most units (like an exterior SSD) are designed round USB4.
USB4 Model 2 is an upcoming customary that may propel USB4 to 80Gbps, which is the one 80Gbps customary but introduced. The primary merchandise will debut (as a guess) in early 2023.
Notice that Thunderbolt 3 and 4 require not less than 15W to energy units plugged into the Thunderbolt port, corresponding to a bus-powered arduous drive. USB4 requires simply half that.
Machine maker Anker has a pleasant abstract of the entire technical options related to Thunderbolt 3, Thunderbolt 4, and USB4, in the event you actually wish to get into the superb distinctions (under).

What cable ought to I exploit with a Thunderbolt dock?
Just about each Thunderbolt dock will ship with its personal cable. We’d suggest that you just use Thunderbolt 3 cables with Thunderbolt 3 merchandise, and Thunderbolt 4 cables with Thunderbolt 4 merchandise.
What differentiates a DisplayLink USB-C docking station from a Thunderbolt dock?
A DisplayLink USB-C docking station is a brand new class of docking station. They’re typically marketed simply as a USB-C docking station, sadly, although the DisplayLink emblem options prominently on the field. The important thing right here is that the DisplayLink expertise (now owned by Synaptics) makes use of software program information compression between your PC and the dock to approximate a Thunderbolt expertise (a pair of 4K shows at 60Hz, plus further peripherals) throughout the narrower, slower USB-C bus. You’ll want to put in a software program driver to make it work.
The benefit right here is twofold. First, DisplayLink means that you can “cheat” and get a Thunderbolt dock expertise on an older laptop computer. Alternatively, even in the event you do personal a laptop computer with a Thunderbolt port, you could possibly discover a DisplayLink USB-C dock for a less expensive worth than Thunderbolt. This can be a viable answer, particularly in the event you don’t thoughts not enjoying PC video games.
Our separate story on DisplayLink docks has extra.
Are there another applied sciences that I must find out about?
We’re beginning to see some USB-C docking stations make the most of one other expertise: HBR3 (Excessive Bit Price 3) with DSC (Show Stream Compression). Consider it because the industry-standard, manufacturer-agnostic model of DisplayLink. It really works over the USB-C port, and once more offers a twin 4K60 show expertise.
The issue? It’s wonky. We’ve discovered that help for the expertise was very iffy in Eleventh-gen {hardware}, and actually appears to work constantly in Twelfth-gen or Thirteenth-gen Core laptops (and above, after they ship). Whereas we will’t actually suggest it proper now, we’re maintaining a tally of it.
The overwhelming majority of Thunderbolt docks ought to embrace a Thunderbolt cable like this one, which signifies that it’s specified for Thunderbolt 3.

Shopping for Information: what to search for in a Thunderbolt dock
Ports, cables, peripherals: These are the three main issues when shopping for a Thunderbolt dock.
We’re starting to see the Thunderbolt dock market break down in just a few other ways. First, there’s the funds versus full-featured docks we’ve highlighted above. However you additionally may even see one thing much like the USB hubs of previous: Units that take Thunderbolt in after which present a number of USB-C (together with Thunderbolt) ports out. There are a small variety of shows with Thunderbolt inputs, which will be plugged straight into these hubs. Do you will have an present low cost USB-C dongle? You possibly can actually plug that in right into a Thunderbolt dock and add much more I/O performance.
Mainly, think about what you’ll wish to plug into the dock as a information for purchasing one. We choose units with ports in-built (corresponding to HDMI, USB-A, and so forth) because the USB-C machine ecosystem remains to be in its infancy. However ask your self some questions. Would you like a fundamental Thunderbolt dock, with only a pair of HDMI ports for connecting two shows? Does an SD card slot matter? What number of USB Kind A peripherals do you propose to connect? Do you wish to use the Thunderbolt cable to cost your laptop computer, too?
Cables will be an unexpectedly vital consideration, too. Just about each dock ships with a Thunderbolt cable. However think about the shows you personal (usually HDMI or DisplayPort) and think about whether or not the dock will accommodate them.
Examine your laptop computer’s energy provide. Does it plug into your laptop computer by way of USB-C? If that’s the case, a Thunderbolt dock will possible energy it. You’ll want to know how the dock provides energy, although. Examine your laptop computer’s charger to learn the way a lot energy it provides, and the way a lot the dock might want to provide to switch it. In case your laptop computer or units aren’t receiving sufficient energy, you might even see a warning pop up.
A “bus-powered” dock received’t include an exterior charger within the bundle, saving some price, area, and energy considerations. A dock with “energy supply” will provide its personal energy and cost your laptop computer and/or a telephone by way of your laptop computer’s present USB-C charger. (Likelihood is that it received’t provide the quick-charging capabilities premium smartphones provide, although.) The extra energy your dock provides, the higher the flexibility to cost your laptop computer and any bus-powered units. This can be a gotcha most individuals don’t take into consideration, so in the event you plan to attach a number of bus-powered arduous drives or SSDs, purchase a dock with a hefty energy provide. (USB keys, however, require tiny quantities of energy. Don’t fear about these.)
Powered Thunderbolt docks, particularly people who energy your laptop computer, can ship with some fairly sizeable energy bricks.
Mark Hachman / IDG
There’s another consideration: the size of the Thunderbolt cable between your laptop computer and the dock itself. You’ll have seen or heard about USB-C ports carrying out on smartphones; a free or wobbly connector on a Thunderbolt dock may cause a monitor to unexpectedly flicker or lose connection. Contemplate how a lot rigidity will probably be placed on a cable. A Thunderbolt dock that’s dangling from a Thunderbolt port will stress the bodily connector. You don’t need that!

How we check Thunderbolt docks
We’re working from the premise that you just’re shopping for a Thunderbolt dock for its distinctive capability to hook up with two 4K screens at 60Hz. Decrease resolutions must be a lot simpler to run efficiently. Our first check merely linked every dock to a pair of 4K/60Hz shows, every of which may settle for DisplayPort and HDMI cabling, and made positive there have been no visible artifacts at 60Hz decision.
Second, we checked to see whether or not the obtainable ports delivered the bandwidth we’d count on, connecting them to an exterior SSD and transferring a group of check information over the Thunderbolt cable and port. We additionally used AJA’s System Check device to double-check our numbers and check whether or not learn and write speeds have been constant.
Lastly, we spot-checked the obtainable energy draw of the hubs and ports with a USB energy meter, in addition to merely connecting them to bus-powered units to see if they may ship sufficient energy to permit them to function.
