Question

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 90 W of power. The Core i5 Ivy Bridge, released in 2012, had a clock rate of 3.4 GHz and voltage of 0.9 V. Assume that, on average, it consumed 40 W of power. For each processor find the average capacitive loads.

Answer 1

We know that

Where, P = consumed power

C_L = Capacitive Load

V = Voltage

f = Switch Frequency

so, average capacitive load can be calculated as

Capacitive load for Pentium 4 Prescott processor

Watt is multiple of Current and Voltage

Ampere is measured as Coulomb per second

Electrical Capacitance (Farad) is Coulomb per Voltage
