At lower engine speeds the engine is already closer to the peak torque, due to a broader torque band, and also the torque is greater than a non-turbo version of the same engine. So, keeping the RPM lower while the vehicle goes at a given speed in both scenarioes (turbo and aspro) is the key for the turbocharged get a greater efficiency. The higher torque also deals better with taller gear ratios.
