“It will be known as USB 3.2 Gen 2×2 according to the USB Implementers Forum”
Names of USB systems are going to get very confusing thanks to the latest plans of the USB Implementers Forum (USB-IF). The new names are meant for the latest USB 3.2, which will double the connection speed to 20Gbps. These ports will start arriving in high-end desktop computers later this year. The USB-IF confirmed this at the Mobile World Congress in Barcelona.
Now, to prepare for the arrival of the new USB 3.2 systems, USB-IF has announced new names for existing USB 3.1 systems. The generation 1 USB 3.1 or USB 3.1 Gen 1, which currently provides speeds of up to 5Gbps, will be known as USB 3.2 Gen 1. And USB 3.1 Gen 2, which provides transfer speeds of up to 10Gbps, will be known as USB 3.2 Gen 2. So far, so good. Just replace 3.1 with 3.2 and you should be good. However, things get a little confusing after this.
Peripherals, including desktop PC’s, which will come with the new USB 3.2 port, will have a different name for these ports. They will be called USB 3.2 Gen 2×2 and these are the ones with the 20Gbps transfer speeds. The USB-IF has also announced new marketing names for all these systems. For example, the USB 3.2 Gen 1 systems will be known as SuperSpeed USB, whereas the USB 3.2 Gen 2 will be called SuperSpeed USB 10Gbps. The USB 3.2 Gen 2×2 ports will be advertised as SuperSpeed USB 20Gbps. Here’s what they have to say about all this:
“SuperSpeed Plus, Enhanced SuperSpeed and SuperSpeed+ are defined in the USB specifications, however, these terms are not intended to be used in product names, messaging, packaging or any other consumer-facing content.”
Manufacturers will have to include all these specifications when selling their products. However, it is possible that a brand could advertise its product having a USB 3.2 port, but it could end being a Gen 1 system. This is the main reason why the USB-IF has given out these new names and branding. As mentioned above, devices with USB 3.2 will start appearing later this year. It will first be available in high-end motherboard and slowly make its way to other devices. USB 3.2 will be backwards compatible with all older USB standards.
