Why did high-volume production lower the cost of microprocessors?

High-volume production lowered the cost of microprocessors primarily because of the significant demand generated by their initial applications in small electronic equipment and industrial devices. This surge in demand necessitated large-scale manufacturing, which allowed producers to achieve economies of scale, where the average cost per unit decreases as total output increases.12

Beyond the efficiencies gained through volume, the cost reduction was further supported by:

• Improved Manufacturing Methods: Advancements in production techniques helped streamline the creation of integrated circuits, making the process more efficient and less expensive over time.1
• Technological Progression: Continued innovation, such as the development of very large-scale integration (VLSI), allowed for greater circuit density on the same size silicon chip. This enabled more powerful microprocessors to be produced without a proportional increase in manufacturing costs.13

These factors created a cycle where lower costs encouraged the integration of microprocessors into a wider range of consumer and industrial products, further driving demand and enabling even greater production efficiencies.1
