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 version | Speed | Encoding | Connectors |
|---|---|---|---|
| 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 |
128 / 130bit | Type a, b (micro), c |

If it finally allows for external GPUs via USB... Otherwise there will be very few people who will actually have real use for it. But hey, everyone will have to pay.

Come on guys you know trying to stick a USB connection into the back of my PC is a nightmare sometimes. That's because it's set up under my desk and by the wall.
If only they invented a USB connection that fits both ways, that would make it much easier. What's that you say, it's already invented but unlucky for me none of my devices have that type of connection. So boohoo to you. Please can you just make one USB port that fits all connections and devices and stop this BS.

I had my fair share of struggles with micro-USB orientation. That struggle was mostly solved though when I got a Galaxy S6, which has wireless charging. My current phone has a USB-C port but I rarely use it since it also has wireless charging, and I prefer the latter. Frankly, I'd welcome USB-C more if inductive charging wasn't a thing (currently, it's more of a nuisance than anything else, as I need an adapter for almost everything).
Now? Sorry, buddy, but I'm so old that most of my phones had a round power plug that had all the orientation demands of a round plug, which is none on the significant axis. Then came the micro-usb and you always had to check. Type-C is a single step back towards the original situation. Like I said, after the much needed speed increase introduced by usb3 (maybe you are so young you were never experienced the slooooooow speed of usb2), this was the only usb change that was worth noticing for me.

i dont even use the 3.1 ports i have and the 3.0 ports i have dont even run past 2.0 speed cause i dont have anything that need the speeds in first place, guess it could usful if i got external hdd that used 3.0 or higher

But, of course - we are saved from extinction now that we do not have to
