Where 4004 fits
Why 4004 is special
It ran at 740 kHz with 2,300 transistors and was built for a Japanese desk calculator. Putting a whole processor on one chip is the step everything after depends on — a modern phone chip holds billions of transistors and is a direct descendant of a component designed to add numbers on a desk.

Technology & computing
The 4004 was built in 1971 for a Japanese desk calculator, ran at 740 kHz and held 2,300 transistors. Everything since depends on the step it represents rather than on its capability: a modern phone processor holds billions of transistors and descends directly from a part designed to add numbers on a desk.
