Computer Hardware Design - Old Questions

4. A program runs in 20 seconds on computer A, which has a 2 GHz clock. We are trying to help a computer designer build a computer, B, which will run this program in 12 seconds. The designer has determined that a substantial increase in the clock rate is possible, but thisincrease will affect the rest of the CPU design, causing computer B to require 1.4 times as many clock cycles as computer A for this program. What clock rate should the designer target? (5)
