Sorry, I should have said USB-C/USB 3.1 gen 2.To be a bit pedantic: USB-C is a form factor, not a protocol. The protocol speeds are like this:
The USB spec tends to rebrand N-1 as N in some form e.g. USB2 'full speed' is actually USB1 speed and the 3.1gen1 thing above, so this list will probably be wrong in the future
- USB 3.1 gen 1 (rebranded USB 3.0) allows for 5gbps over a single lane
- USB 3.1 gen 2 allows for 10gbps over a single lane
- USB 3.2 gen 2x2 allows for an extra lane, so 2x 10gbps or 2x 5gbps.
- Thunderbolt 3 allows for 40gbps over an USB-C cable
However Thunderbolt 3 does not allow for 40Gbps over a USB-C cable, they might look the same (but for the lightening bolt and the 3 on them) but they don’t perform the same. If you want Thunderbolt 3 speeds you have to use Thunderbolt 3 cables.
