It's also because the power consumption is quadratic with the frequency.
This is important if you agree that an additional hour on battery is worth much more than few cylces per sec.
- gcb 14y agoThat's why your cpu runs on different paths to save power when not needed. Using a lower cpu is just lazy and cheap.
- Dave_Rosenthal 14y agoNo, the first-order model is that power consumption is quadratic with voltage, and linear with frequency.
- bnegreve 14y agoOk, but isn’t increasing the voltage required to keep the transistors stable as you increase the frequency ?
- Karunamon 14y agoThat's kind of irrelevant anyways, all modern CPU's have speed stepping functionality that can reduce the clock speed while on battery.
