Thunderbolt three and USB-C are often talked about in the identical breath, which may make understanding the distinction between the 2 fairly difficult for the common individual.
Each are connection applied sciences, however they do perform in several methods. Right here’s all the things you want to find out about USB-C, Thunderbolt three, how they overlap, and what their specialties are.
What’s the actual distinction?
USB-C is among the newest USB designs, a really vital improve for the USB port that added some essential options, together with the power to (ultimately) join regardless of facet was up, and the power to ship as much as 100 watts of energy to cost gadgets. It could additionally present information switch speeds as much as 10Gbps, and helps video for a 4K show — though the connection does want converters to correctly output audio information.
Then we’ve got Thunderbolt. Thunderbolt was a connectivity expertise developed by way of a partnership between Intel and Apple, a mix of PCI Categorical, DisplayPort and DC energy applied sciences. This makes Thunderbolt a flexible connection choice for the gadgets that help it, and Thunderbolt three is at present the quickest, strongest model accessible. As you may count on, Thunderbolt connections are often discovered on Apple merchandise, though different manufacturers all over the world have made use of them as properly.
Now comes the sophisticated half: The 2 connection applied sciences have been separate for quite a lot of years, supporting completely different gadgets for various folks. Nonetheless, as time handed this grew to become much less possible, and the 2 applied sciences began to resemble one another extra.
By the point the USB-C port kind confirmed up, each applied sciences have been related sufficient that Thunderbolt was designed to attach utilizing solely USB-C ports. So, we noticed firms start so as to add additional Thunderbolt three to USB-C connections in order that the USB-C ports may very well be used as Thunderbolt three, primarily including Thunderbolt capabilities to the brand new USB-C ports.
What capabilities does Thunderbolt three add?
Thunderbolt three is a step up from what USB-C alone can provide. It does rather a lot, however the important thing options of the connection embrace:
40Gbps speeds, far quicker than what USB-C can provide by itself
Help for as much as 2 4K shows or a 5K show for routing video and audio out
Native audio help
Particular cables are required for longer connections, which do result in a lower in information speeds
Serial connection of a number of gadgets linked collectively and accessed by one pc
And, after all, compatibility with all gadgets that require a Thunderbolt three connection, in addition to all USB gadgets
Can a port be USB-C however not Thunderbolt three?
Sure, it may well. Many USB-C ports don’t have Thunderbolt three capabilities, and solely provide connections via the USB three.1 (Gen 1/Gen 2) protocol. That is why, in the intervening time, ports have an ungainly naming system that should explicitly state, “USB-C Thunderbolt three” so folks realize it helps each choices. Units are being made which have the power to make use of both USB-C or Thunderbolt three connections on these ports based mostly on what they want or help.
Nonetheless, observe that the reverse just isn’t true; A Thunderbolt three port, by design, may also perform as a USB-C port. There is no such thing as a separate, particular Thunderbolt three port, as there was for previous variations of the Thunderbolt connection. Nonetheless, there are particular Thunderbolt three cables which are used to entry the total capabilities of the connection, so preserve that in thoughts when shopping for. When you’re simply searching for USB-C cables, we’ve got a listing it’s possible you’ll need to take a look at.
You may inform in case your USB-C helps the Thunderbolt three normal is by searching for the small Thunderbolt emblem. Whether or not it’s ports on a laptop computer or on a cable itself, a Thunderbolt port is often accompanied by the emblem. There are some exceptions although, so all the time verify the specs of the actual product in query.
So, Thunderbolt three is best than simply USB-C?

USB-C is much from a nasty port: It’s a lot quicker than previous generations and really versatile, with the welcome skill to cost up accent gadgets. So don’t really feel like it’s important to get a Thunderbolt three port for those who don’t really want one. However sure, in a head-to-head comparability Thunderbolt three is best than USB-C in mainly each manner.
With USB4 on the best way, it’s catching up quickly. However because it stands, sure, Thunderbolt three is a quicker and extra succesful normal. So, why don’t firms simply flip all USB-C ports into Thunderbolt three?
Bear in mind, USB and Thunderbolt spent a few years as siloed, aggressive applied sciences. They’re beginning to converge, nevertheless it’s nonetheless a course of and system compatibility stays a problem in some instances (as does what to really name the brand new, unified port).
Thunderbolt three connections additionally require further, specialised , which raises the price of gadgets. Some firms won’t need to embrace this additional expense fairly but, particularly not a extra budget-oriented gadgets. Different firms might choose to save cash by making just one port on their gadgets Thunderbolt three, whereas maintaining the opposite ports USB-C. This additionally makes the system simpler to design and energy.
Lastly, Thunderbolt three requires that the system be powered by Intel, which guidelines out many merchandise proper from the get-go.
