USB 3.2 introduced to make USB branding even more confusing



 USB Type-C Power Cable

The USB Implementers Forum (USB-IF) has formally introduced USB 3.2 at MWC 2019 (via Tom's Hardware ). The upcoming format, which will offer the current maximum USB data transfer speeds to deliver up to 20GB per second, has brought about a rebrand for USB 3.1 products.

USB 3.2 will be known by the technical name USB 3.2 Gen 2 × 2 seeing as it uses two high-speed 10 Gbps channels. It succeeds to USB 3.1 Gen 2, which will now be called USB 3.2 Gen 2, while the previous USB 3.1 Gen 1 will be renamed USB 3.2 Gen 1.

It's a confusing name change, especially since USB 3.1 Gen 1 is also used to be called USB 3.0. However, USB-IF has suggested some marketing terms that can make the products easier to understand, if manufacturers adopt them. These are:

  • SuperSpeed ​​USB 20Gbps (USB 3.2 Gen 2 × 2)
  • SuperSpeed ​​USB 10Gbps (USB 3.1 Gen 2)
  • SuperSpeed ​​USB (USB 3.1 Gen 1, which tops out at 5Gbps)

How will USB 3.1 Gen 2 × 2 affect smartphone users?

USB 3.1 Gen 2 × 2 only works with USB-C, which most new Android smartphones will have, but we'll need to wait for next-generation chipsets to benefit from it. The Qualcomm Snapdragon 855, which will power many 2019 flagship phones, only supports 10Gbps transfer speeds through the newly named USB 3.1 Gen 2.

However, even once the supporting technology is there, this is probably not something smartphone owners need worry too much about it. Few Android users will transfer large enough files to really benefit from the 20Gbps connection. It's more something that power users on a laptop or desktop would use.
