USB 3.2 Specification Published and Announced

USB 3.2 Specification Published and Announced

A while ago there was already word out on the street that the USB Focus group would be announcing a new draft for upcoming USB 3.2, that has now been finalized and published. To keep things really simple, we're doubling thing up once again.

Where USB 3.0 aka 3.1 Gen1 was capable of 5 Gbps connectivity, USB 3.1 Gen2 did 10 Gbps. USB 3.2 will double that up-towards 20 Gbps. Divide it by 8 bits and that would be 2500 MB/sec from which you need to deduct encoding and errors. There is a distinction though as it is based up-on two-lane operation as tweakers.net spotted today.

Key characteristics of the USB 3.2 solution include:

  • Two-lane operation using existing USB Type-C cables
  • Continued use of existing SuperSpeed USB physical layer data rates and encoding techniques
  • Minor update to hub specification to address increased performance and assure seamless transitions between single and two-lane operation

So basically using two 10 Gbit/s lanes you get towards a throughput of 20 Gbps. Obviously you will need a host and client connection that is compatible with the new standard. Current USB type C cabled would be compatible if they have been certified for 10 Gbps SuperSpeed USB. If you like to do some reading, there is a 548 page document available on the new 3.2 Spec, download here.

USB versionSpeedEncodingConnectors
USB 2.0 (incl usb 1.0 and 1.1) up to 480 Mbps 8 / 10bit Type a, b (mini, micro), c
USB 3.1 Gen 1 (SuperSpeed Usb) up to 5 Gbps 8 / 10bit Type a, b (mini, micro), c
USB 3.1 Gen 2 (SuperSpeed usb Gbps) up to 10 Gbps 128 / 130bit  Type a, b (micro), c
USB 3.2 (SuperSpeed usb 20 Gbps)

up to 2 lanes 5 Gbps
up to 2 lanes 10 Gbps

128 / 130bit  Type a, b (micro), c

This is getting annoying already. I hate what industry does nowadays by moving at such a fast pace that even consumers cannot keep up.
Why they don't just release USB 4.0 with 1Tbps, with 1KW of power and call it a day for the next 10 years? They like to create one million revisions and release them once a week, like somebody would care.
I know that shareholders are crazy for more money and that new stuff drives the market and the sales in general, but come on! Take a vacation, enjoy some wine and live the life. Computers from 5 years ago are still very much ok and USB 3.0 is still plenty enough for pretty much everything you could possibly need.

Usb specs are becoming insane.

I only recently learned there was gen 1 and gen 2 3.1.


Why can't they just make a motherboard with 6x 3.2 slots and 6x 3.2 type c slots....or is type c going to become one of those jokes where is was one of those standards no one adopted.

Most motherboards I have seen have 1x type c slot....why even bother.

That lonely USB-C port is enough for Apple's Earpods lol.

Seems like USB doesn't feel "Universal" anymore. It's a huge fragmented mess. Different protocols and different connectors at the same time.
They have to settle down and let people adopt it. USB-C should've been the new standard connector it's been a while now since it was released but still no more than 1 Type-C connector on new motherboards. No front panel C towers either. This doesn't help adoption. It's a mess.
