Best Thunderbolt 4 And USB4 Cables For 2022

Best Thunderbolt 4 And USB4 Cables For 2022

Thunderbolt 4 is the new connection standard in town and you need Intel-certified cables to take advantage of all its benefits.

With the arrival of Thunderbolt 4, choosing the right cable for USB-C and Thunderbolt computers and devices has become a lot easier.

The short answer, which I’ll explain here, is that if you’re looking for absolutely the best cable to buy for USB-C, Thunderbolt 3 or Thunderbolt 4, you should aim for an Intel-certified Thunderbolt 4 cable. The same goes for USB-C and USB4.

If someone needs to buy a Thunderbolt 3 cable right now they might as well buy a universal Thunderbolt 4 cable since it is backwards compatible with everything, and they have the benefit of future-proofing their cable. 

Thunderbolt 4 is simpler and more powerful
Previously, there were USB-C cables and Thunderbolt 3 cables, and each could be “Active” or “Passive”. 

In the previous generation, it was important to distinguish between Passive and Active for backwards compatibility, but with Thunderbolt 4 it’s not as much of a consideration since the Active 2m cables are backwards compatible with Thunderbolt 3, USB4, USB 3.0, USB 2.0 etc – unlike Thunderbolt 3 Active cables that were backwards compatible with only USB 2.0.

A passive USB cable merely carries data that's transferred through it.

An active USB cable includes small electronic circuits that boost the intensity of the data carried by the cable, which can stop signal degradation due to the length of the cable. There are active Thunderbolt 3 cables that can hit 40Gbps bandwidth at 2m. But you can expect to pay a lot more for active cables than shorter passive ones – around double the price of passive cables.

Note that USB-C is just the connector. The data transfer speed or bandwidth is determined by the version of USB it uses. USB speeds range from slow USB 2.0 (480Mbps) to fast USB 3.2 Gen 2x2 (20Gbps), with Thunderbolt 3 and 4 reaching 40Gbps.
And the length of the cable matters, too.

USB-IF, the official USB Implementers Forum, dictates that passive USB 3.2 Gen 1 (5Gbps) cables should be at most 2 metres, while USB 3.2 Gen 2 (10 Gbps) cables can reach only up to 1 metre if it is to keep transferring data at its maximum speed.

An active USB-C 3.2 Gen 2 cable can be up to 3m in length.

The maximum length of a passive Thunderbolt 3 cable is just 0.8m at full 40Gbps bandwidth, or 2m at 20Gbps bandwidth.

What is Thunderbolt 4?
Thunderbolt 4 is the latest version of Intel's Thunderbolt line. It is backwards compatible with Thunderbolt 3 and USB-C, and has a range of benefits.

All certified Thunderbolt 4 cables work with everything, including USB4, USB 3.2, USB 3.1, and even USB 2.0 – no matter their length.

Thunderbolt 4 allows for up to 40Gbps data transfer, 100W power delivery (PD) and laptop charging. This was true of Thunderbolt 3, but some Windows PC and laptops used cut-down versions. To be officially certified as Thunderbolt 4 by Intel, all manufacturers have to supply the top specifications TB4 offers.

TB4 can also support high-resolution displays up to 8K (7,680-x-4,320) or any USB-C monitor. Buying a USB-C display means you can use a Thunderbolt 4 cable that’s much thinner than a DisplayPort or HDMI cable. It can also be used with many devices other than displays, unlike video cables.

Previously, 2m cables could not be used with USB-C monitors – a limitation rectified by Thunderbolt 4.

Thunderbolt 4 benefits
  • Support for two 4K displays or one 8K display
  • 40Gbps bandwidth
  • PCIe at 32Gbps for data-storage speeds up to 3,000MBps
  • Support for docks with up to four Thunderbolt 4 ports
  • Up to 100W PD charging on at least one computer port
  • Wake the computer from sleep by touching the keyboard or mouse when connected to a Thunderbolt dock
  • Intel VT-d direct memory access (DMA) protection to prevent physical DMA attacks
With Thunderbolt 3, only passive cables were backwards compatible (and then only at a feeble 480Mbps), meaning longer active TB3 cables worked with TB3 devices only.

In comparison, 2m Thunderbolt 4 cables support all versions of USB, so buying Thunderbolt 4 will future-proof your cable purchase as well as offer backwards compatibility.

With a TB4 cable, you gain the versatility to connect USB-C devices to Thunderbolt ports.

In addition, since Thunderbolt 4 supports USB4, if someone needs a USB4 cable they can use a Thunderbolt 4 cable.

One of the benefits of Thunderbolt 4 cables for USB4 users is that Thunderbolt 4 cables always support up to 40Gbps – USB4 is rated at either 20Gbps or 40Gbps, so TB4 is ready for both.

You can attach a powerful wall charger up to 100W, but note that Thunderbolt and USB-C charging functionality is dependent on your host computer’s charging capabilities. Some Windows PC manufacturers limit charging on their ports. Either way, a TB4 cable is capable of the maximum.

With Thunderbolt 4 there is no compatibility difference between passive and active, and Intel-certified 0.8m, 1m and 2.0m cables should act exactly the same.

Cables are currently available in lengths of either 0.7m (2.3ft), 0.8m (2.6ft), 1m (3.2ft) or 2m (6.6ft).

There are certainly more options on the length and looks with other recommended USB-C and Thunderbolt 3 cables, but Thunderbolt 4 cables win on features and backwards/future compatibility. 

Like Thunderbolt 3, Thunderbolt 4 ports and cables show the small lightning bolt logo, which helps to differentiate TB4 from USB4 and older USB-C 3.2 ports. Thunderbolt 4 cables include a small number 4 underneath the lightning bolt logo.

What is USB4?
USB4 takes over from the often confusing USB 3.0 to 3.2, offering either 20Gbps or 40Gbps data speeds. It uses the same rounded, reversible Type-C connector as USB-C, Thunderbolt 3 and 4.

A Thunderbolt 4 cable is also a USB4 cable, but not all USB4 cables will be certified for use with Thunderbolt 4 or even Thunderbolt 3 – which is another reason that a TB4 cable is our universal recommendation.

USB4 is more efficient than older USB variants at sharing between data and display protocols as it can dynamically monitor bandwidth requirements for connected displays and save the remaining bandwidth for data transfer. Older USB simply split the bandwidth in two for display and data.

USB4 can support Power Delivery up to 100W.

And, like Thunderbolt 4, USB4 is backwards compatible with USB 3.2, USB 3.1, USB 3.0, USB 2.0, and Thunderbolt 3.

A certified USB4 cable will feature the USB logo plus either the number 20 or 40 depending on the speed (20Gbps or 40Gbps) it is rated at.
