Intel released the 4004 in November 1971. Its design team included Federico Faggin, Ted Hoff, Stanley Mazor and Masatoshi Shima.
The chip was designed for the Japanese calculator company Busicom. Other early processor designs existed for military and aerospace uses.
The world before
Computers had processors built from many separate parts, the size of cabinets.
The human achievement
The 4004 had about 2,300 transistors and ran at 740 kHz. Intel’s 8080 (1974) powered early personal computers, and the 8086 family became the basis of the PC. Apple, Commodore and others used rival designs.
Understanding the invention
The Microprocessor, explained in two steps.
Step 01 of 02
The processor reads an instruction, works out what it means and does it, billions of times a second.
IV
The transformation
Individuals and small firms could own computers.
Embedded chips control cars, washing machines and medical devices.
Cheap, programmable processors went into computers, cars, appliances and phones.
Before and after
Before
A large institution.
After
A desktop machine at home.
