Hello,
One benchmark of the speed of a CPU is the number of instructions it can perform with each clock cycle. How many clock cycles will a 3.06 GHz computer have?

Clock rates should not be used when comparing different CPUs families. Rather, software benchmarks should be used. Clock rates can be very misleading since the amount of work different CPUs can do in one cycle varies. For example, superscalar processors can execute more than one instruction per cycle (on average), yet it is not uncommon for them to do "less" in a clock cycle. In addition, subscalar CPUs or use of parallelism can also affect the performance of the computer regardless of clock rate.
