Reply to comment by SoarinPastTheMoon in Better Than Fans? New 'AirJet' Chip Promises To Overhaul Laptop Cooling by Avieshek

You can't compare power usage of a x86 core and an ARM because one was designed for high performance, and the other was designed for low power consumption. It's also why every cell phone uses an ARM processor.

It's like comparing the fuel economy of a Ford 350 and a Prius. Sure, if all you want to do is drive around town, the Prius will get you there just as fast, and it'll do it for 1/3 the gas.

Why not, when ARM chips get similar or better performance? When the output is the same and one consumes far less power for it, why shouldn’t you compare the power usage?
