Not so much an increase in top end speed, as although it does give it longer legs the engine is lacking the torque to push past the other factors at play like drag.
It's similar to riding a bicycle, that sure you can slot it into a harder gear that "could" take you faster, but try as you might your legs just don't have the strength to push the pedals up to the speed that is possible.
What you do notice however with the 16T is the more practical side of things at the lower speed end, like 1st gear becomes more useable, and there's one less gear change to get up to highway speeds when giving it the berries.
