Apple would possibly combine up connector sorts amongst its 4 iPhone 15 fashions, and which may confuse individuals much more over the variations between USB-C and Thunderbolt. They appear alike, work equally and settle for the identical cables. But they’re not the identical.
Let’s take a look at the important thing variations, how Thunderbolt 4 improves on Thunderbolt 3, and which sort of port and cable most closely fits your duties like charging and information switch.
USB-C versus Thunderbolt
USB-C and Thunderbolt are each common of their most up-to-date iterations, showing throughout several types of computer systems and different gadgets.
They appear alike and are suitable with one another. However they’re totally different in essential methods. In a nutshell, Thunderbolt is at the moment as much as 4 instances quicker for data-transfer than USB-C.
That’s excellent news for iPhone 15 Professional and Professional Max patrons, if rumors of a Thunderbolt connector on them come true.
Defining USB-C
USB-C, finalized in 2014 when the three.1 specification got here out, is an industry-standard, 24-pin connector that transfers each information and energy between gadgets. It’s turning into the usual for system charging, as Apple bids adieu to Lightning connectors in its gadgets.
USB-C’s present model is USB4, which got here out in 2019. In numerous gadgets, a USB-C connector can change (or add to) the performance of connectors like USB-A, USB-B, HDMI, DisplayPort and three.5mm audio jacks.
To confuse issues a bit extra, USB4 2.0 might come out earlier than the top of 2023 with twice the bandwidth of the present model.
Defining Thunderbolt

Thunderbolt, created in 2011 by a collaboration between Intel and Apple and initially referred to as “Gentle Peak,” provides much more performance to at least one cable and connector than USB-C does.
It combines PCI Categorical and DisplayPort alerts — information and video — plus energy, multi function cable/connector. Thunderbolt 1 and a couple of used the Mini DisplayPort connector. Thunderbolt 3 and 4 use the USB-C connector.
What’s the distinction?
Thunderbolt is quicker than USB-C and clearly the higher selection for information switch. It might additionally ship extra energy, however that isn’t mandatory for many charging purposes.
Utilizing the identical connector, USB-C, is what makes Thunderbolt and USB-C look alike. However Thunderbolt carries extra data and goes rather a lot quicker. In comparison with USB-C two-lane street, it’s like a superhighway with extra lanes.
Thunderbolt 3 doubled the capability of Thunderbolt 2, with 4 lanes of PCI Categorical basic information and 4 lanes of DisplayPort video information.
Thunderbolt 4 caught with its predecessor’s most information switch velocity of 40Gbit/s — 4 instances quicker than USB 3.2 Gen 2 — but it surely added help for twin 4K shows, safety enhancements and Thunderbolt Alternate Mode for USB hubs along with daisy chaining.
When you’re constructing a pc setup, go for Thunderbolt 4 connectivity wherever you possibly can for the quickest and most strong information switch. It’ll depend for lots everytime you’re connecting gadgets to switch information, and particularly the place video is worried.
What connectors and cables must you use?

The query above is actually answered by which sort of connector you could have. You probably have a Thunderbolt connector — it would have a lightning-bolt image above or beside it — then you could have Thunderbolt, not plain USB-C.
If there isn’t a Thunderbolt image, then it’s a USB-C connector. The identical cables will work with each, however when gadgets with totally different capabilities are linked, you solely get the bottom widespread data-transfer price.
For USB-C, cables and connectors marked USB 3.1 or “SS” (for Tremendous Velocity) would be the quickest. USB 2.0 cables will even work, however they gained’t switch information or cost a tool as quick. The truth is, they’re as sluggish as Lighting connectors, at 480Mbps.
When you could have Thunderbolt gadgets to attach, be sure to use a Thunderbolt cable. Similar to the ports, it would have a lightning bolt image on its USB-C connector at every finish. Solely a Thunderbolt cable will get you Thunderbolt velocity and strong information and energy switch.
And bear in mind, simply because you could have Apple gadgets, you don’t want to purchase (probably expensive) Apple cables. Each USB-C and Thunderbolt are common, and so are the cables that work with them.
