Thunderbolt™ technology, created by Intel®, steps up USB port technology by supporting both high‐speed data and video. Harnessing Thunderbolt technology through a USB-C port created in partnership with USB-IF, Thunderbolt 3 is the fastest port available. It connects Thunderbolt devices, all HD and 4K displays, and billions of USB devices using 1 compact, reversible plug—transferring 4x the data and 2x the video bandwidth of any other cable.1

Cheat Sheet

Gbps (stands for gigabits per second)

A unit of data transfer rate measuring bandwidth speed by the billions of bits transferred per second.

Standard USB (stands for Standard Universal Serial Bus)

The most common universal connector on the “other end” of most current USB cables, Standard USB is often suitable for use with computers, car chargers, wall chargers, and many other devices.

USB port (stands for Universal Serial Bus port)

A port designed for use with an industry standard connector to communicate data and supply electric power between devices.

USB 3.1

USB 3.1 is the updated, Gen 2 version of USB 3.0. Gen 2 successfully doubled the transfer speed rate of Gen 1(USB 3.0), taking USB from 5 Gbps to 10 Gbps.

USB-C (also known as Type-C)

A new type of USB connector, hailed as the new standard. Smaller, faster, and more user-friendly than previous USB types, USB-C has widespread support from industry leaders, meaning USB-C will come to replace all other USB types.

USB-IF (stands for USB Implementers Forum)

A non-profit organization founded by the companies that developed the Universal Serial Bus (USB) specification. The USB-IF’s mission is to support and advance USB technology.

4K (short for 4,096 pixels of resolution)

Quickly becoming the new standard for high-quality digital video, 4K refers to a horizontal resolution of 4,096 pixels, or “4K” pixels.

Mini DisplayPort

A miniaturized version of the DisplayPort interface, Apple developed audio-visual digital interface Mini DisplayPort in 2008.
