The next generation of USB interface, USB 3.2 is expected to hit the desktop market later this year. USB 3.2 will provide a staggering 20GBps of throughput. This is achieved by allowing for two lanes of 10GBps each, which can be achieved without reducing the cable length.

Well, this is about the only thing that’s straightforward as the naming mess around the USB speeds is going to get even worse.

The naming was quite simple and straightforward through USB 3.0:

  • USB 1.1 (12MBps)
  • USB 2.0 (480MBps)
  • USB 3.0 (5GBps)

Then USB 3.1 was introduced in July 2013, and the USB-IF (USB Implementers Forum) decided to confuse everyone . And now, with coming of USB 3.2 this year, the USB-IF is going to make things even worse.

  • USB 3.1 Gen 1 rebranded to USB 3.2 Gen 1
  • USB 3.1 Gen 2 rebranded to USB 3.2 Gen 2
  • The new 20GBps USB 3.2 branded to USB 3.2 2×2

This new confusing naming for USB speeds will allow manufacturers to state that their device supports USB 3.2 without providing any further information that will let the consumers know whether they are getting the 5,10 or 20 GBps.

This will also make buying A USB-C cable even more frustrating than it is today. Only compatible USB-C cables will be able to provide the 20 Gbbps speed as only these have the dual lanes needed to double the effective speed.
