Visualizing empirical "laws" of the industry

## Transitors

Moore's "Law" states that the *number of transistors in CPUs will double every two years* (sometimes incorrectly quoted as the speed doubling every two years).

## Bandwidth

Nielsen's "Law of Internet Bandwidth" states that users' bandwidth grows by 50% per year. This is harder to validate with open data. As a proxy, here's the download rate of popular communication technologies by release date:

## Efficiency

Koomey's law states *the number of computations per joule of energy dissipated doubles about every 2.6 years*.
Here's the numerical computing performance vs. power rating of the top 500 most energy efficient supercomputers over the last decade:
