The Pentium 4 Prescott processor, released in 2004, had a clock rate of 3.6 GHz

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 10 W of static power and 90 W of dynamic 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 30 W of static power and 40 W of dynamic power. 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.

Explanation / Answer

1) The average capacitive load for both of the precessors is given by the formula:

Capacitive load = Dynamic power / (0.5 * V2 * Clock rate)

For Pentium 4 Prescoott Processor, Capacitive Load = 90 / ( 0.5 * (1.25)2 * 3.6 * 109) (since 1 GHz - 109 Hz)

= 3.2 * 10-8

For Core i5 , Capacitive load = 40 / (0.5 * (0.9)2 * 3.4 * 109)

= 2.904 * 10-8

So, we can see that the capacitive load on the core i5 processor is less than that of the Pentium 4 Prescoot processor.

2) Ratio of the static power to the dynamic power for each of the technology is given as:

For Pentium 4 Prescoot processor.: Static power / Dynamic Power

= 10 / 90 = 0.11

For core i5: Static power / Dynamic Power

= 30 / 40

= 0.75

As, the question is not completely mentioned, still I've covered the neccessary concepts through numerical computations.
