Moore’s Law: what is its essence

Moores Law was developed in 1965 by Gordon Moore, the founder of Intel. The law describes the regular improvement of computer performance. In 1997, studies confirmed it, although in fact it is not entirely correct to call the formulation in question a law.

Moore’s Law states that the performance of computers and technical devices doubles approximately every 18 months. Accordingly, it is rather not a law, but an empirical rule. The original plan was to double the capacity once a year. However, following further reviews, this period was extended to two years.

Gordon Moore in 1965 derived another rule to his theory, which states that technical and economic factors jointly influence the development of the production of technical devices or integrated circuits. The cost of the final product, however, does not change during this time. Thus, more powerful devices should appear on the market without a noticeable increase in prices. This law has been confirmed by many chip manufacturers, as they were guided by the statement of the founder of Intel. Products were made in accordance with Moore’s law, and the prediction came true.

Why Moore’s Law no longer works

Since it is possible to work on computers even with molecular and atomic processes, already several decades ago, experts believed that from 2015 the law would no longer be applied. Currently, it really no longer works, but for other reasons. In particular, because of the boundaries of the physical world.

Circuits in chips are getting smaller and eventually they will become so small that they can no longer be used. From that moment, the laws of quantum physics will begin to operate. In addition, processor clock speeds no longer increase at the rate specified by law. The clock speed indicates how many instructions a processor can execute, and constantly increasing it in accordance with the formulation of the law is hampered by problems of power consumption and overheating of processors.
