How I check Thunderbolt docks
A separate article goes into element about how I check Thunderbolt docks. However right here’s a brief synopsis.
First, I take the dock from its packaging and consider its building. I measure the Thunderbolt twine size and examine the dock’s bodily dimensions with a ruler.
I’ll then learn the handbook: Does the dock want any drivers? Are there hyperlinks? What does the handbook say concerning the dock’s capabilities by way of energy and velocity?
Subsequent, I take a USB key or two and join them to the accessible USB ports to find out if they’ve sufficient house to permit a number of to be related on the identical time. I then look at the show ports, discover the suitable cables, after which join the dock to the laptop computer. I exploit a collection of laptops with varied generations of AMD and Intel {hardware}, and examine to see if the expertise is similar on every one. If it isn’t, I make notes. I join the dock to 2 4K shows, operating at 60Hz. For Thunderbolt 5 docks, I’ll use two 4K shows able to 144Hz — that’s the restrict of the know-how.
I then measure the ability output of the ports, utilizing a USB multimeter, a smartphone, and a laptop computer to measure how a lot energy the dock delivers to every.
Lastly, I examine to see how nicely the dock performs beneath load. I exploit a selected check laptop computer for this objective for repeatable outcomes.

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 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 determine them. However some laptop computer makers use an identical lightning-bolt icon to point {that a} USB-C port can be utilized for charging your cellphone, and not for Thunderbolt. Laptop computer makers typically don’t wish to litter the clear traces of their merchandise by including further logos, it appears. Fortuitously, most laptops now select to spotlight their Thunderbolt capabilities, so the ports must be well-marked.
In June, Intel held a technical session speaking about its upcoming Lunar Lake processor. One of many large modifications that it’s making is to a) cluster the entire older USB-C ports on one aspect of the laptop computer, away from the Thunderbolt and b) require the ports (together with Thunderbolt) to be clearly labeled. That’s a small however vital win for customers and ensures every part is clearly marked.
You may additionally 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 will probably be restricted by the accessible bandwidth that the port gives, so it’s considerably misleading in that regard.

Two laptops, each with USB-C ports, and each with lightning-bolt symbols. Which laptop computer provides Thunderbolt? The highest one, although it may be tough to inform. Consulting the producer’s specs is your most secure guess.

How briskly is Thunderbolt?
Put merely, 40Gbps, for Thunderbolt 4.
Most USB-C ports are constructed on the second-generation USB 3.1 data-transfer normal, which transfers knowledge at 10Gbps. Thunderbolt 3 and 4 ports, the most typical normal, 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 gained’t discover the distinction.
Intel unveiled an 80Gbps model of Thunderbolt earlier this yr, known as Thunderbolt 5, that means that you just’ll see Thunderbolt docks with much more capabilities when units ship this yr. In sure eventualities, it may possibly reroute knowledge to ship 120Gbps in a single route. That spec has been introduced, and two (as of this writing) laptops have been introduced with a discrete Thunderbolt 5 chip inside: a model of the Razer Blade and the Maingear ML-17. We even have one Thunderbolt 5 dock that’s shipped, too.
There’s additionally a USB 3.2 Gen 2×2 spec that may pair two 10Gbps channels collectively, creating an combination 20Gbps hub. (That is actually just for exterior gaming-class SSDs.) 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. You don’t want to fret about this.
What ought to I purchase: Thunderbolt 3, Thunderbolt 4, or Thunderbolt 5?
The brief reply: I like to recommend both a Thunderbolt 3 or Thunderbolt 4 dock for now. They’re primarily the identical factor, and you may rating a deal as retailers proceed to filter outdated Thunderbolt 3 stock.
Thunderbolt 5 is the 80Gbps model, however will probably be backwards suitable with each Thunderbolt 3 and 4. With solely a handful of laptops that assist the spec and only a single dock that does, Thunderbolt 5 isn’t one thing to fret about fairly but.
For the sake of completeness, we’re going to element a number of the variations under. However in the event you’re new to this, allow us to reiterate: Thunderbolt 3 and 4 are principally the identical, and Thunderbolt 5 gained’t be a difficulty till later in 2024.
Consider Thunderbolt 4 because the extra restrictive model of Thunderbolt 3, with much less room for any gotchas.
Basically, Thunderbolt 3 and Thunderbolt 4 permit as much as 40Gbps most bandwidth, sufficient for 2 4K/60 shows. “As much as” is the important thing phrase: Thunderbolt 3 is simply 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, nonetheless, and our really useful docks assist the complete 40Gbps 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 wish to attempt that strategy.
Thunderbolt 4 doesn’t permit 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 helpful. Thunderbolt 4 permits for longer cables and extra Thunderbolt ports on laptops, too.
Machine maker Anker has a pleasant desk of the entire technical options related to Thunderbolt 3, Thunderbolt 4, and USB4, in the event you actually wish to get into the high-quality distinctions (under). What’s USB4? We handle that additional down.
I already personal a USB-C dongle. Can I exploit it with Thunderbolt?
A 10Gbps USB-C dongle gained’t substitute a 40Gbps Thunderbolt dock, as there’s circuitry throughout the dock that enables it to work along with your laptop computer’s high-speed Thunderbolt port. Nevertheless, there’s nothing saying that you may’t join the dongle to an accessible USB-C port on the Thunderbolt dock itself so as to add much more ports. In case your laptop computer has two Thunderbolt ports, you may also connect a Thunderbolt dock to 1 port, and the dongle to the opposite.
That answer will add extra litter to your desk, nevertheless it may mean you can purchase a less expensive, finances dock, too. It’s as much as you!

My laptop computer says it has a USB4 port, not Thunderbolt. Can I exploit it with a Thunderbolt dock?
Most likely. USB4 ports usually seem on laptops with AMD Ryzen processors inside. USB4 and Thunderbolt 4 are suitable and functionally equal. (Although Thunderbolt is an open normal, Intel declines to certify non-Intel {hardware}. That signifies that Ryzen laptops find yourself with USB4 ports, and Intel Core laptops embody Thunderbolt.)
USB4 is actually a subset of Thunderbolt 4, primarily designed as an an I/O specification.
As a subset of Thunderbolt 4, a USB4 machine will run simply high-quality plugged right into a Thunderbolt 4 port. However dock makers inform us {that a} Thunderbolt 4 machine might not work as anticipated when plugged into what’s particularly a USB4 port. As an alternative, most hubs and docks are marketed as Thunderbolt 4, whereas most units (like an exterior SSD) are designed round USB4. (We check Thunderbolt docks on Thunderbolt laptops.) There are USB4 docks, nonetheless, which you’ll discover above in our listing of finest picks.
USB4 Model 2 is an upcoming normal that can propel USB4 to 80Gbps, identical to Thunderbolt 5. The primary merchandise will debut (at a guess) in early 2024, however the USB-IO hasn’t given us a precise timeline or the capabilities of USB4V2 docks.
Word that Thunderbolt 3 and 4 require not less than 15W to energy units plugged into the Thunderbolt port, akin to a bus-powered arduous drive. USB4 requires simply half that.
I did attempt to join a Thunderbolt 5 dock to a USB4 laptop computer, and it didn’t work. It ought to! It could simply be a driver difficulty.
What’s so vital about Thunderbolt 5?
Thunderbolt 5 debuts in 2024, each in laptops in addition to docks and units. Though we noticed a few early merchandise at CES 2024, we’ve solely seen two TB5 laptops as of this writing: a model of the Razer Blade and the Maingear ML-17. Each have discrete chips inside, fairly than being instantly built-in contained in the processor. One Thunderbolt 5 dock has shipped, the Kensington SD5000T5.
Why does that matter? If a perform like Thunderbolt 5 isn’t constructed proper into the processor, a laptop computer OEM should purchase it individually. That takes time, cash, and engineering, and most laptop computer makers assume arduous earlier than spending further.
I’m getting extra of a “it seems like 2025” vibe, consequently. Thunderbolt 5 assist isn’t included in Intel’s upcoming Lunar Lake cellular processor, and leaks counsel that Arrow Lake (which can be an Intel desktop processor in addition to a cellular chip) might not have assist for Thunderbolt 5, both. That also leaves room for the discrete Thunderbolt 5 controller, however means that built-in Thunderbolt 5 may wait till 2025 or perhaps even 2026 with Panther Lake. Nevertheless, the primary Thunderbolt 5 cable debuted not too long ago, although a number of the cable lengths are most likely too brief to be sensible.
The Thunderbolt 5 spec pushes I/O bandwidth from 40Gbps in Thunderbolt 4 to 80Gbps in Thunderbolt 5, and even to 120Gbps in some circumstances. One other great way to think about Thunderbolt 5 is within the context of what it may possibly do. Thunderbolt 4 permits sufficient bandwidth for 2 4K shows, operating at 60Hz. Thunderbolt 5 will provide sufficient bandwidth to hook up with three 4K shows, at 144Hz apiece. That helps make Thunderbolt 5 a gaming-class know-how, fairly than simply for workplace work.
Thunderbolt 5 can even permit for 64Gbps of devoted bandwidth for storage and exterior GPUs, double the 32Gbps on Thunderbolt 4.
Lastly, there’s energy. Thunderbolt 5 will present as much as 240W (140W required) of charging energy to your laptop computer. Most laptops require 65W to 90W in the present day, however gaming laptops require extra. All this implies is {that a} Thunderbolt 5 dock will probably remove the necessity to carry a gaming laptop computer’s charger round. (It gained’t be in all circumstances, however some.) Word that you just’ll want a laptop computer that helps this energy spec, nonetheless!
What’s Thunderbolt Share? How does it work?
Thunderbolt Share is a brand new means of connecting two PCs through a Thunderbolt cable. Plug one finish of the cable into one Thunderbolt port, and the opposite right into a Thunderbolt port on one other laptop computer, and voila! They’re related. Thunderbolt Share permits you to use one PC to manage one other, sync information, share information, and extra, all at Thunderbolt speeds. I clarify Thunderbolt Share and check it, right here.
It sounds easy, straightforward, and highly effective, nevertheless it’s extra sophisticated than that. Each PCs must run Intel’s Thunderbolt Share software program, and also you’ll solely have the ability to get that from a licensed PC or Thunderbolt dock. Thunderbolt 4 and Thunderbolt 5 will run Thunderbolt Share, however not Thunderbolt 3 — nicely, formally. The identical goes for USB 4; it may work, and it may not. Intel isn’t saying.
Thunderbolt Share will probably be supported by a handful of PC makers in addition to dock makers like Belkin, Plugable, and extra. Learn my story for extra particulars.
What cable ought to I exploit with a Thunderbolt dock?
Nearly each Thunderbolt dock will ship with its personal cable. We advocate that you just use Thunderbolt 3 cables with Thunderbolt 3 merchandise, and Thunderbolt 4 cables with Thunderbolt 4 merchandise. Ditto for the primary Thunderbolt 5 cables, when the know-how ships in 2024.
My Thunderbolt docking station solely has Thunderbolt connections, however I would like to attach it to my monitor. How can I join a Thunderbolt dock to my HDMI show?
You’ll want a particular USB-C to HDMI cable, rated for Thunderbolt speeds. I like to recommend and have bought this Uni Thunderbolt to HDMI cable from Amazon, which is about $16. You could find cheaper choices, however make certain they’re rated for both Thunderbolt or a 4K@60Hz show.
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 brand options prominently on the field. The important thing right here is that the DisplayLink know-how (now owned by Synaptics) makes use of knowledge 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 your PC to speak with the DisplayLink chip constructed into the dock.
The benefit right here is twofold. First, DisplayLink permits you to “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 might be able to discover a DisplayLink USB-C dock for a less expensive value than Thunderbolt. It is a viable answer, particularly in the event you don’t thoughts not enjoying PC video games.
Our separate story on DisplayLink docks has extra.
What’s HBR3 with DSC?
We’re beginning to see some USB-C docking stations reap the benefits of one other know-how: 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 gives a twin 4K60 show expertise.
The issue? It’s wonky. We’ve discovered that assist for the know-how 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). It’s turning into extra widespread, and works extra stably in the latest Intel Core laptops.
Can I exploit an exterior graphics card (eGPU) with Thunderbolt?
Thunderbolt 3? Sure, you possibly can. Sure producers (Razer is one, although there are others) have constructed enclosures that may home a regular desktop graphics card, related to your laptop computer through a Thunderbolt cable. Though a cellular gaming laptop computer with an exterior GPU does a very good job enabling cellular gaming, a desktop GPU does even higher. Thunderbolt merely connects the 2.
Exterior GPU assist kind of skipped Thunderbolt 4, nonetheless, and I might advocate utilizing a Thunderbolt 3 dock as an alternative, or wait till Thunderbolt 5. How are you going to hook up an exterior GPU to your laptop computer through Thunderbolt? Our story has extra.
The one eGPUs I’ve seen with Thunderbolt use Thunderbolt 3, not Thunderbolt 4. Why is that?
Based on a consultant for Razer, the variations between Thunderbolt 3 and Thunderbolt 4 have been too small. “After we launch any product, we solely accomplish that when there generally is a materials benefit over the earlier era,” we have been instructed.
Since Thunderbolt 4 was backwards suitable and functionally equal to Thunderbolt 3, Razer merely declined to put money into the manufacturing and testing of a Thunderbolt 4 eGPU. We presume different producers adopted swimsuit.

The overwhelming majority of Thunderbolt docks ought to embody 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.
I like a Thunderbolt docking station that’s powered sufficiently to energy my laptop computer. Nearly each dock ships with a Thunderbolt cable. However take into account the shows you personal (with usually HDMI or DisplayPort connections) and take into account whether or not the dock will accommodate them. I choose docks with devoted show ports, so {that a} show with an HDMI port, for instance, can join instantly. I am seeing a small however rising proportion of Thunderbolt docks that embody a Thunderbolt cable to your laptop computer after which devoted Thunderbolt connections out to shows. These docks are likely to cater to Mac customers. Nevertheless, you should buy a dongle or cable that converts Thunderbolt/ USB-C to HDMI or DisplayPort, or else you should buy a USB-C show.
Principally, take into account what you’ll wish to plug into the dock as a information for purchasing one. Ask your self: 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 intend to connect? Do you wish to cost your smartphone?
Examine your laptop computer’s energy provide. Does it plug into your laptop computer through USB-C? If that’s the case, a Thunderbolt dock will doubtless 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 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 gained’t include an exterior charger within the package deal, saving some price, house, and energy considerations. At the moment, these are fairly uncommon.
A dock with energy supply will provide its personal energy and cost your laptop computer and/or a cellphone through your laptop computer’s present USB-C charger. What I’ve discovered is that some docks, particularly one with a free Thunderbolt port, will provide sufficient energy for even in the present day’s most fashionable fast-charging smartphones with out specific assist for them.

Powered Thunderbolt docks, particularly those who energy your laptop computer, can ship with some fairly sizeable energy bricks.

There’s yet another consideration: the size of the Thunderbolt cable between your laptop computer and the dock itself. You could have seen or heard about USB-C ports sporting out on smartphones; a free or wobbly connector on a Thunderbolt dock may cause a monitor to unexpectedly flicker or lose connection. Think about 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!
We’re beginning to see some docks with an SSD enclosure inside. It’s doable that this can turn into extra of a viable product over time, however for now it’s nonetheless area of interest.
In the event you’re a Mac consumer who has stumbled throughout this text, welcome. However please bear in mind 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 not too long ago left destructive opinions on Thunderbolt docks on buying websites due to this. Apple additionally hasn’t explicitly dedicated to Thunderbolt 5, both.
