On July 25, 2017, The USB 3.0 Promoter Group comprised of Apple, HP, Intel, Microsoft and other technology firm announced the pending update to the USB 3.2 specification.
What is USB-3.2?
The new USB 3.2 supports multi-lane operation, doubling of bandwidth for existing USB-C cables.
Now the USB-C SuperSpeed certified cables i.e., USB 3.1 Gen 1 cables will allow operating at 10Gbps before it was operated on 5gbps and The USB 3.1 Gen 2 SuperSpeed+ certified cables now able to operate at 20 Gbps before it allows speed up to 10Gbps. The new USB 3.2 gives you the 2x speed on existing USB-C cables.
When a USB 3.2 host connected to a USB 3.2 recipients will capable of 2GB/sec data transfer speed over a USB-C cable certified for SuperSpeed 10Gbps USB 3.1 said by USB Promoter Group.
USB-C carries data from numerous devices such as Apple’s Thunderbolt, HDMI, DisplayPort and the of course from USB 3.1 gen 1 and gen 2 – which is the current official data transfer standard for USB-C
To take an advantage of speed gain on existing USB-C cables, you will need a new hardware which supports the USB-3.2 specifications. On the current scenario, no motherboard or laptops or any other component features a USB 3.2 connectivity. So, the new USB 3.2 specification will apply on the next generation hardware. Might be we will able to see this new speed gains on existing USB cables later this year.
When we introduced USB Type-C to the market, we intended to assure that USB Type-C cables and connectors certified for SuperSpeed USB or SuperSpeed USB 10 Gbps would as produced, support higher performance USB as newer generations of USB 3.0 was developed,” said Brad Saunders, USB 3.0 Promoter Group Chairman. “The USB 3.2 update delivers the next level of performance.”
