The Intel 4004 is an early single chip computer chip, from 1971, and a lineal ancestor of the Pentium family of computer chips.[1][2]

intel 4004 specifications
specification value
number of transistors 2,300 transistor on die[1][2]
clock speed 108 hertz[2], 740 hertz[1]
bus speed 108 hertz[2]
instruction set 46 instructions[1]
Registers 16 4 bit registers or eight bit registers.[1]
introduction date November 1971[2]
memory 1k data memory, 4k program memory[1]
address space 4k[1]
transistor size 10 micron[2]

The computer had separate data and memory spaces. The maximum addressable memory was 4 kilobytes.[1]

According to the History of Computing website the chip "it is widely considered to be the world's first commercial single-chip microprocessor."[1]
