Using Amdahl's Law for Energy Efficient Performance Estimation?

While trying to find an answer to my previous question, I stumbled across the paper "Extending Amdahl's Law for Energy-Effic

TeraFLOP in 20W by 2020?

In 1996, a TeraFLOP was possible with only one computer in the world.  By

Visual Studio 2010 Built-in CPU Acceleration

Writing the sample code for this post I was amazed myself to see how simple it was to reach over 20 times performance improvement with so little effort.

Why P scales as C*V^2*f is so obvious (pt 2)

THE GORY DETAILS

Let’s continue from where we left off last time. Let’s figure out the why of the equation,

P = C * V^2 * (a * f)

Why P scales as C*V^2*f is so obvious

[Warning: Math and physics alert! Math and physics alert!] I think that you've all seen this equation before: P = a * C * V2 * f

So how are P-states related to power management?

This relationship between P-states, voltage and frequency is well and good, but how does this relate to power management? Power is literally, energy usage per unit of time.

There's got to be a catch

I hate moving. Nothing ever goes as it should. It takes 10 times longer than you expected. And that last box is finally unpacked just before you end up moving again.

(update) C-states, C-states and even more C-states

As I said before, a C-state is an idle state. The processor isn't doing anything useful, so why not shut some things off? Think of it in terms of your house.
