What is Dennard scaling?
The rule that shrinking transistor dimensions and supply voltage by the same factor gives faster, denser circuits at constant power density. It broke down in the mid-2000s when voltages could no longer be lowered easily.
Dennard scaling in the explanations
Dennard scaling is the rule that shrinking transistor dimensions and voltage by the same ratio makes transistors faster and smaller while keeping power per unit area constant.
Which correctly describes Dennard scaling?With the end of Dennard scaling, power per transistor no longer drops enough as transistor counts rise, so running every circuit on a chip at once would exceed thermal limits and some must stay idle—dark silicon.
