Part 4 of 4 (Innovation Changers)
What is performance per Watt?
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)
[Warning: Math and physics alert! Math and physics alert!] I think that you've all seen this equation before:P = a * C * V2 * f
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.
What is a P-state?
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.
Right now we have 4 PC laptops in our house; 5 if you count the iPad 2 being a ‘personal computing’ device.
