Advanced Topic 51 of 51 Computer Architecture & Logic

Moore's Law and Dennard Scaling

Historical trends in transistor density and power.

How it works

Moore observed transistor counts doubling roughly every two years; Dennard scaling said power density stayed constant as transistors shrank. The latter ended around 2005, so clock speeds plateaued.

Where it is used

Explains the shift to multicore and accelerators.

Common pitfall

Treat Moore's law as a trend, not a law; it has been slowing.

Where it fits in the course

Moore's Law and Dennard Scaling is topic 51 of 51 in Computer Architecture & Logic, rated Advanced. It follows ARM and RISC-V. It is the last topic in this area.
