[2.4] The Pentium 4 Prescott processor, released in 2004, had a clock rate of 3.6 GHz and voltage of 1.25 V. Assume that, on average, it consumed 10 W of static power and 90 W of dynamic power. The Core i5 Ivy Bridge, released in 2012, has a clock rate of 3.4 GHz and voltage of 0.9 V. Assume that, on average, it consumed 30 W of static power and 40 W of dynamic power. a. For each processor find the average capacitive loads. Ans. Pentium 4: C = 3.2x10 Farad(F) Core i5: C= 2.9x108 F b. Find the percentage of the total dissipated power comprised by static power and the ratio of static power to dynamic power for each technology. Ans. Pentium 4: 10%- Core i5: 42.9% age be c. If the total dissipated power is to be reduced by 10%, how much should the reduced to maintain the same leakage current? Note: power is defined as the product of voltage and current. Ans.
