The Shape of Code » Dennard scaling a necessary condition for Moore’s law (opens in new tab)

Dennard scaling was necessary, but not sufficient, condition for Moore’s law to play out over many decades. Transistors generate heat, and continually adding more transistors to a device will eventually cause it to melt, because the generated heat cannot be removed fast enough. However, if the fabrication of transistors on the surface of a monolithic silicon semiconductor follows the Dennard scaling rules, then more, smaller transistors can be added without any increase in heat generated pe...
