Computer Architecture Review – Moore’s Law

This is a review on Moore’s law.

The number of components per integrated circuit will increase at a factor of two per year. The phenomenon doesn’t translate to performance doubling every two years. A graph shows that Transistor Scaling has contributed to 17% – 19% of the improved performance. Architectural Design innovation contributed additional 13-21% per year.

The problem with Moore’s law in the future is that Copper’s resistivity is increasing (instead of staying constant) because of “second order effects”. Capacitance is hard to improve. As a result, there is no near solution for continuing the doubling of transistors.
