The "nanosecond switching" isn't really impressive either, since it wouldn't be able to keep up with a 1 GHz clock because RTL involves signals passing through several gates (and each gate is made up of multiple transistors unless it's a not gate) each cycle, so if each of those take a nanosecond, that limits the clock rate to 1 / number of transistors GHz, which it also wouldn't be able to hit because signals also take time to travel along the wires between transistors.

For 5 GHz, signals must make it from one register, through all of the logic, and latch properly into the next register in 0.2 ns.
