USB 3.2 will introduce major performance boost for existing Type-C cables

The USB 3.0 Promoter Group - which includes Microsoft, Apple, Intel, HP, and others - has announced the USB 3.2 specification.

USB 3.2 will enable USB devices to use all four pairs simultaneously, providing a simple way to double performance of existing cables.

On the plus side, you won't need new cables, as the original USB-C cables were created to eventually be used with the higher speeds - that is, as long as they've been certified for SuperSpeed USB 10GBps.

"New USB 3.2 hosts and devices can now be designed as multi-lane solutions, allowing for up to two lanes of 5 Gbps or two lanes of 10 Gbps operation", the Group said.

What do you think of USB 3.2?

The only small inconvenience is that to use these new speeds you'll need brand new devices at each end of the cable.

Type-C is a reversible cable that is meant to charge all of your gadgets and even serve as a new audio jack, video output or charger. Assuming your cables are USB-C 3.1 compatible. There was much more margin for error prior to USB Type-C.

USB-C can carry data across numerous connections such as Apple's Thunderbolt, Displayport, HDMI, and, of course, USB 3.1 - which is now the official data transfer standard for USB-C. For example, a USB 3.2 host connected to a USB 3.2 storage device will now be capable of realizing over 2 GB/sec data transfer performance over an existing USB Type-C™ cable that is certified for SuperSpeed USB 10 Gbps.

Now, with the upcoming release of USB 3.2 specification by the USB 3.0 Promoter Group, the capabilities of the Type-C connectors have become greater than before. However, in the case of USB 3.2, the theoretical bandwidth cap would max out at 20Gbps. While current generation of USB only uses single-lane operations, USB 3.2 will be able to utilise multi-lane operations in order to offer the 2x performance boost. The hub specification is being changed to ensure that it can properly handle switching between two pair and four pair operation, but that's the full extent of the changes. The USB 3.2 specification is now in a final draft review phase with a planned formal release in time for the USB Developer Days North America event in September 2017.
