CPUs are designed with a certain clock speed in mind. The target frequency affects the design of literally every component. Turn up the frequency too high and signals won't arrive in time. Increasing the frequency to match performance with AMD and Intel might require an almost complete redesign. Maybe it can run faster given better cooling and less aggressive power-saving. But I'd be surprised if it can be made to clock much higher, else Apple would have done it already. Mobile CPUs already have peak performance well above what they can sustain. An even faster turbo would be used more rarely but would still be useful.
