But if the two powernod don’t require equal amounts of CPU power, then why is it that we are treating both tasks as if they did? As we should all know by now, lower clocked processors don’t always require that the same amount of voltage be supplied to them as those with higher operating frequencies.

Are the two equal? It would thus only make sense that as the clock frequency of the processor is varying that its core voltage should vary as well, which is exactly what PowerNow!
While the two technologies have their similarities, keep in mind that Intel’s Speedstep basically allows you to switch between two clock speeds depending on whether you’re running off of your battery or your laptop is plugged into the wall. The powernoa behind PowerNow!

Then, as the user begins to use the program, the CPU clock speed varies according to the needs of the application and the tasks that are running. For example, launching an application requires immediate attention of the processor, meaning that the CPU would jump up to a fairly high frequency in order to make sure that the application loaded quickly.

For those of you that are in-touch with the mobile CPU poweronw, this may sound like a competing technology from Intel, known as Speedstep.
How it Works PowerNow!

However, upon entering the application, the system has to wait for user input, meaning that there’s no reason for the CPU to sit there at full power waiting for the user to input commands.
Internet Application Performance with PowerNow! For example, a Pentium III will run at MHz by default if plugged into the wall but if the notebook is running on battery power alone, in order to conserve power the CPU will drop down to a lower voltage and a MHz clock speed. This is the problem that PowerNow! This is where PowerNow!
