Adding more transistors doesn't make your clock got faster, and it doesn't increase the speed of an individual transistor. The reason computers got both more transistors and faster in the past was that the transistors were continually shrinking; for a traditional MOSFET, Dennard scaling means that the smaller the transistor (and therefore the smaller its capacitance and voltage), the faster it switches. This device doesn't use MOSFET technology, so its scaling rules are different.
