FAQ
How do I do know if my laptop computer has Thunderbolt?
The brief reply: Take a look at the laptop computer’s revealed specs to make sure. A Thunderbolt port could look indistinguishable from a USB-C port, since they each use the identical bodily USB-C connection. Put one other approach, 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 determine 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 cellphone, and not for Thunderbolt. Laptop computer makers generally don’t wish to muddle the clear traces of their merchandise by including extra logos, it appears.
Including to the confusion, you might also see USB-C hubs marketed as “Thunderbolt compatible.” That’s true. You’ll be able to plug a Thunderbolt dock right into a non-Thunderbolt, generic USB-C port. However it is going to be restricted by the accessible bandwidth that the port supplies, so it’s considerably misleading in that regard.
Two laptops, each with USB-C ports, and each with lightning-bolt symbols. Which laptop computer presents Thunderbolt? The highest one, although it may be tough to inform. Consulting the producer’s specs is your most secure wager.
IDG
I already personal a USB-C dongle. Can I take advantage of it with Thunderbolt?
A USB-C dongle received’t exchange 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 you can’t join the dongle to an accessible USB-C port on the Thunderbolt dock itself so as to add much more ports.
That resolution will add extra muddle to your desk, however it would possibly can help you purchase a less expensive, price range 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 knowledge at 10Gbps. Thunderbolt 3 and 4 ports, the commonest customary, switch knowledge 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 most likely 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 mixture 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 assist web page, for instance, particulars its four-lane and two-lane laptops.) Basically, a 20Gbps connection needs to be sufficient for a single 4K monitor operating at 60Hz, with a bit of additional bandwidth for different knowledge 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 you can rely upon them for 32Gbps of information, not a full 40 Gbps. Intel’s Twelfth-gen and Thirteenth-gen Core chips supply essentially the most constant Thunderbolt expertise, with 40Mbps Thunderbolt 4 speeds, together with 32Gbps for knowledge 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 brief reply: Not that a lot, and we contemplate Thunderbolt 3 docks and Thunderbolt 4 docks to be functionally equal for many customers. The longer reply, which we’ll describe beneath, 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. “Up to” is the important thing phrase: Thunderbolt 3 is barely required to assist 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 advisable docks assist the complete specification (and two 4K shows) except 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 attempt that method.
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 probably 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 basically 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 assist one show, and producers can select whether or not it helps a 20Gbps connection or a 40Gbps connection, in accordance with Thunderbolt dock designer Plugable. As a subset of Thunderbolt 4, a USB4 machine will run simply positive plugged right into a Thunderbolt 4 port. However a Thunderbolt 4 machine could 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.
Be aware that Thunderbolt 3 and 4 require no less than 15W to energy units plugged into the Thunderbolt port, reminiscent of a bus-powered onerous drive. USB4 requires simply half that.
Machine maker Anker has a pleasant abstract of all the technical options related to Thunderbolt 3, Thunderbolt 4, and USB4, should you actually wish to get into the positive distinctions (beneath).
Thunderbolt dock and I/O hub designer Anker offered this abstract of the variations between Thunderbolt 3 and Thunderbolt 4.

What cable ought to I take advantage of with a Thunderbolt dock?
Just about each Thunderbolt dock will ship with its personal cable. We’d advocate 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 usually 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 knowledge compression between your PC and the dock to approximate a Thunderbolt expertise (a pair of 4K shows at 60Hz, plus extra 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 lets you “cheat” and get a Thunderbolt dock expertise on an older laptop computer. Alternatively, even should you do personal a laptop computer with a Thunderbolt port, you could possibly discover a DisplayLink USB-C dock for a less expensive value than Thunderbolt. It is a viable resolution, particularly should you don’t thoughts not taking part in PC video games.
Our separate story on DisplayLink docks has extra.
Are there some other applied sciences that I have to find out about?
We’re beginning to see some USB-C docking stations make the most of one other expertise: HBR3 (Excessive Bit Charge 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 supplies a twin 4K60 show expertise.
The issue? It’s wonky. We’ve discovered that assist 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, once they ship). Whereas we are able to’t actually advocate 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 a couple of alternative ways. First, there’s the price range versus full-featured docks we’ve highlighted above. However you additionally may even see one thing much like the USB hubs of outdated: Gadgets 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 may have an present low-cost USB-C dongle? You’ll be able to definitely plug that in right into a Thunderbolt dock and add much more I/O performance.
Mainly, contemplate what you’ll wish to plug into the dock as a information for purchasing one. We desire units with ports inbuilt (reminiscent of HDMI, USB-A, and so forth) because the USB-C machine ecosystem continues 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 essential consideration, too. Just about each dock ships with a Thunderbolt cable. However contemplate the shows you personal (sometimes HDMI or DisplayPort) and contemplate whether or not the dock will accommodate them.
Test 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 grasp how the dock provides energy, although. Test 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 interchange 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 package deal, saving some price, area, and energy issues. A dock with “power delivery” will provide its personal energy and cost your laptop computer and/or a cellphone by way of your laptop computer’s present USB-C charger. (Chances are high that it received’t supply the quick-charging capabilities premium smartphones supply, although.) The extra energy your dock provides, the larger the flexibility to cost your laptop computer and any bus-powered units. It is a gotcha most individuals don’t take into consideration, so should you plan to attach a number of bus-powered onerous drives or SSDs, purchase a dock with a hefty energy provide. (USB keys, alternatively, require tiny quantities of energy. Don’t fear about these.)
Powered Thunderbolt docks, particularly those 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 could have observed 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 pressure 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!
Should you’re a Mac consumer who has stumbled throughout this text, welcome. However please remember that early Apple MacBook Execs powered by Intel silicon supported as much as two 4K shows. The primary MacBook Execs powered by the Apple M1 chip solely assist a single 4K show. Many Mac customers have lately left destructive opinions on Thunderbolt docks on buying websites due to this.

How we check Thunderbolt docks
We’re working from the premise that you just’re shopping for a Thunderbolt dock for its distinctive means to hook up with two 4K screens at 60Hz. Decrease resolutions needs to 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 certain there have been no visible artifacts at 60Hz decision.
Second, we checked to see whether or not the accessible ports delivered the bandwidth we’d count on, connecting them to an exterior SSD and transferring a set of check information over the Thunderbolt cable and port. We additionally used AJA’s System Take a look at device to double-check our numbers and check whether or not learn and write speeds have been constant.
Lastly, we spot-checked the accessible 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 might ship sufficient energy to permit them to function.
