The USB 3. 2 specification announced by the USB Implementers Forum (USB-IF) in 2017 will be arriving soon, and it'll bring a relatively convoluted new naming structure with it. As was the case when the USB 3.
1 specification launched, the new USB 3. 2 spec will absorb the previous generations before it, designating them as Gen 1 and Gen 2.
The new USB 3. 2 specification, which brings speeds up to 20Gbps, will be known as USB 3. 2 Gen 2x2. Joining this will be USB 3. 2 Gen 1, which originally launched as USB 3. 0 and was later renamed USB 3. 1 Gen 1; this specification supports transfer speeds up to 5Gbps.
Between the two will be USB 3. 2 Gen 2, which originally launched as USB 3. 1 and was late renamed USB 3. 1 Gen 2; this specification supports transfer speeds up to 10Gbps. In order to hit the 20Gbps speed, USB 3. 2 Gen 2x2 will utilize two of these 10Gbps high-speed channels.
To help consumers understand which version they're getting, the USB-IF suggests manufacturers use the following terms:
USB 3. 2 Gen 1: 'SuperSpeed USB'
USB 3. 2 Gen 2: 'SuperSpeed USB 10Gbps'
USB 3. 2 Gen 2x2: 'SuperSpeed USB 20Gbps'
According to The Verge, the new USB 3. 2 specification will hit the market sometime this year.
