Did you know... Why the Athlon doesn't run at 5V

A Palomino running at 1.4Ghz is fair game for this....

It consumes about 64W at 1.75V. That means it is drawing approximately 36.57A from it's voltage regulator. (P=IV)

Modeling the CPU as a resistor would give it a resistance of 0.048 Ohms( From R=V/I which gives 1.75/36.57)

Now we have the resistance, we can calculate how much extra power would flow at 5V.

So, for 5V, using I=V/R we get 104.49A worth of current. This is easy to convert into watts, by simply multiplying by the voltage. After all that work we get...

522Watts (104.49*5)

Hence, a good reason why the Palomino does not run at 5V.

Any views, thoughts and opinions are entirely my own. They don't necessarily represent those of my employer (BlackBerry).

Well, maybe your Palomino doesn't run at 5V
