Confused about USB-C transfer speeds of latest MacBook Pros I was reading this 
article about the next iteration to USB-C ports. It says that the new standard will double speeds from 5 Gbps to 10 Gbps. 

It also says:


if you just bought a brand new computer with USB-C port, 
like, for example, the 2016 MacBook Pro that I'm using to write this 
article, you're pretty much screwed.



But according to Apple’s website their USB-C ports 
support up to 40 Gbps data transfer speeds. So this is 4 x faster
than what the above article is saying about the new USB standard. 

Can someone explain this to me? I am confused.
The USB-C ports on your MacBook support USB 3.1 (gen 2) AND Thunderbolt 3.

USB 3.1 gives you a transfer speed of 10 Gbit/s and Thunderbolt 3 is capable of up to 40 Gbit/s.

Note however that just because a device has an USB-C connector that doesn't imply that it supports USB 3.1 gen 2 and thus 10 Gbit/s. It can also be USB 3.1 gen 1, which is basically USB 3.0, which is 5 Gbit/s.
