At What Scale Does Quantum Mechanics Impact CPU Functionality?

Click For Summary
SUMMARY

The discussion centers on the impact of quantum mechanics on CPU functionality, particularly as semiconductor technology advances to 5nm processes. Intel's 14nm Broadwell CPUs mark a significant milestone, but experts like Bob Colwell predict that the end of Moore's Law will occur in the 2020s. Quantum mechanics is essential for understanding the limitations of classical computation in semiconductor devices, such as transistors. The conversation also highlights emerging technologies, including the integration of graphene with silicon, which may address these limitations.

PREREQUISITES
  • Understanding of semiconductor physics
  • Familiarity with Moore's Law and its implications
  • Knowledge of CPU architecture, specifically Intel's 14nm and 5nm technologies

A few weeks ago I heard that Intel released 14nm CPU (Broadwell). After that I did some research and found out that by 2020s we humans will have 5nm CPUs and that will be the end of Moor's law according to Bob Colwell.

My question here is at what scale does the quantum mechanics kick in and classical computation can no longer be performed?
