For a new version of processor, suppose the capacitive load remains, how much more energy will the processor consume if we increase voltage by 20percent and increase clock rate by 20percent? I do not want you to answer the question for me, but please give me the step to solve this. How do I solve this problem.

72.80 % more energy will be consumed.

Explanation:

First of all, let us have a look at the formula of energy for a processor.

Where, is the energy

is the capacitance

is the voltage and

is the clock rate.

Let be the energy of older processor.

be the capacitance of older processor.

be the voltage of older processor

be the capacitance of older processor

So, ....... (1)

and

Let be the energy of newer processor.

be the capacitance of newer processor.

be the voltage of newer processor

be the capacitance of newer processor

....... (2)

Dividing equation (2) with equation (1):

As per given statement:

Putting the values above:

Energy consumed by newer processor is 1.728 times the energy consumed by older processor.

OR

72.80 % more energy will be consumed by the newer processor.
