USB-C 3.1: The Battle of Generations

USB 3.1 Generations Infographic


USB-C THE BATTLE OF GENERATIONS

What is USB-C?

  • USB-C is the latest version of Universal Serial Bus (USB).
  • It is a low-profile connector that is reversible, putting an end to fumbling with ports.
  • Its biggest advantage is the ability to provide power, video and audio output, data transfer and Ethernet all in one connector type.

Confusion: USB 3.0 & USB 3.1

  • In a nutshell, USB 3.0 is exactly the same as USB 3.1 – but only Generation 1. USB 3.1 brings with it the Type-C connector, but provides the same power and data transfer capability as USB 3.0.
  • Visible difference: USB-A 3.0 is blue inside.

Benefits of USB Type-C

USB-C knocks out the need for cables and dongles – just one cable can do so much.

  • It is slim, small and reversible
  • Ultra-fast data transfer speeds up to 10Gbps
  • Up to 100w of power that can safely charge laptops
  • Universal compatibility with all USB devices and legacy devices
  • Removes the need for legacy ports/cables

Generation 1 vs. Generation 2

  •  Gen 1: 5 Gbps data transfer speed => Supports up to 65W => Max cable length: 6ft => Thinner cable
  • Gen 2: 10 Gbps data transfer speed => Supports up to 100W => Max cable length: 3ft => Thicker cable

Who wins?

  • USB 3.1 Gen 1 is good, but Gen 2 is better. Moving 4K UHD movies, huge photo galleries, music albums and other large data is nearly instant. All it requires is a USB Type-C 3.1 Gen 2 cable.
  • As with anything USB – Gen 2 is backwards compatible.
