Overview
The Intel 4004, released on November 15, 1971, was the first commercially available microprocessor, marking a significant technological and economic milestone in computing. Developed by Intel Corporation for Busicom Corp, the 4-bit CPU was priced at $60, equivalent to $477 in 2025. The Intel 4004 was the first significant commercial example of large-scale integration, utilizing MOS silicon gate technology (SGT) to integrate the CPU into a single chip, enabling twice the transistor density and five times the operating speed of existing technology. This innovation paved the way for future single-chip CPUs and accelerated the adoption of SGT by the world's semiconductor industry, influencing companies like Texas Instruments and Motorola. The introduction of the Intel 4004 had a profound impact on the development of personal computers, with companies like Apple Computer and Microsoft later leveraging microprocessor technology to create revolutionary products. As of 2025, the legacy of the Intel 4004 continues to shape the technology industry, with its influence visible in modern CPUs from AMD and NVIDIA.
🎵 Origins & History
The Intel 4004 project originated in 1969 when Busicom Corp commissioned Intel Corporation to design a family of seven chips for electronic calculators, including a three-chip CPU. The team, led by Ted Hoff and Stanley Mazor, developed the 4-bit 4004 CPU, which was the first significant commercial example of large-scale integration, using the abilities of the MOS silicon gate technology (SGT) to integrate the CPU into a single chip. The MCS-4 chipset design, of which the 4004 was a part, served as a model on how to use SGT for complex logic and memory circuits, accelerating the adoption of SGT by the world's semiconductor industry, including companies like Fairchild Semiconductor and National Semiconductor.
⚙️ How It Works
The Intel 4004 CPU was a significant innovation in computing, as it marked the first time a CPU was integrated into a single chip. The 4004 used MOS silicon gate technology (SGT) to achieve twice the transistor density and five times the operating speed of existing technology, making future single-chip CPUs feasible.
