The clock speed only refers to the frequency of instructions executed per unit time . But some CPUs can handle more complex instructions which may be equivalent to several basic instructions in the case of previous gen CPUs . Architecture also matters , hence an efficient Architecture may increase the work done per unit time , irrespective of the clock speed . So in order for a cpu to be a beast , it should have a good efficient architecture and good clock speed .
Plus in some cases lower clock speeds in some modern CPUs are also because they want it to be more energy efficient while being powerful enough to take any load which is well within its limit .
solved CPU speeds don’t make any sense
