PowerNow! – AMD’s K+ in Notebooks – Evaluating Performance with PowerNow

Are the two equal? This is the problem that PowerNow! The whole idea behind PowerNow! 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.

The premise behind PowerNow!

But if the two tasks don’t require equal amounts of CPU power, then why is it that we are treating both tasks as if they did? Internet Application Performance with PowerNow!

AMD’s K6-2+ in Notebooks – Evaluating Performance with PowerNow

How it Works PowerNow! Log in Don’t have an account? Content Creation 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 akd MHz clock speed. This is where PowerNow!

It would thus only make sense that as the clock frequency of the processor is varying that its core techology should vary as well, which is exactly what PowerNow! 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. 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.

Think about how much power your CPU must devote to running a word processing application, now think about how much power is required for a CPU to playback a DVD video stream. For those of you that are in-touch with the mobile CPU industry, this may sound like a competing technology from Intel, known as Speedstep.

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.
