Thunderbolt

Thunderbolt
Thunderbolt simplifies connecting peripherals while also speeding up data transfers.

Thunderbolt is a high-speed hardware interface developed by Intel (with Apple’s collaboration) that combines data, video, audio, and power in a single cable.

Think of it as combining the functions of multiple other standards. Instead of needing separate ports for USB, DisplayPort, and power, Thunderbolt merges them into one versatile connection that’s very fast and flexible.

Multiple Thunderbolt versions

Data transfer speeds available from the developing standard have grown dramatically:

  • Thunderbolt 1 (2011): 10 Gbps
  • Thunderbolt 2 (2013): 20 Gbps
  • Thunderbolt 3 (2015): 40 Gbps
  • Thunderbolt 4 (2020): 40 Gbps (but with stricter feature requirements)
  • Thunderbolt 5 (2023): Up to 80 Gbps, and in some modes, 120 Gbps for video.

Thunderbolt vs. USB-C

Some people are unclear about the relationship between Thunderbolt and USB-C. If this is you, be sure to read Cult of Mac’s guide on the differences between USB-C and Thunderbolt.

Apple sometimes mixes up connector types among devices, and that might confuse people even more over the differences between USB-C and Thunderbolt. The connectors look alike, work similarly and accept the same cables. Yet they’re not the same.

Let’s look at the key differences, how the ascendant Thunderbolt 5 improves on Thunderbolt 4, and which kind of port and cable best suits your tasks like charging and data transfer.

Thunderbolt cables cost far more than standard USB-C ones, and a series of X-ray scans of various options reveals why. The virtual teardown shows that the Apple Thunderbolt 4 (USB‑C) Pro cable has far more features than one might expect for such a simple accessory. Cheaper ones are as bare-bones as could be expected.

The scans are both beautiful and informative.

Thunderbolt hubs add super-fast ports to your Mac, speeding up your workflow. But these hubs also require a really bulky power adapter … usually. The just-announced Sanho HyperDrive Thunderbolt 4 Power Hub is the exception. It’s small enough to travel with.

I tested the Thunderbolt hub in my home office for a couple of weeks to see how it stands up to real-world use.
