Intel's processor history: the path from the Intel 4004 to the Pentium 4

1972: The Intel 8008

Simultaneously with the Intel 4004, Intel developed the 8008. It had an 8-bit wide data bus, was clocked with 200 kHz, had 3,500 transistors and was also manufactured in 10 micron technology. The processor was mainly used in the manufacturing industry.

1974: The Intel 8080

Intel brought a real successor for the first timeof a chip, the Intel 8080. Unlike the 4004, the 8080 was an 8-bit microprocessor that had 6000 transistors and was still manufactured using 6-micron technology. The clock frequency also increased to a respectable 2 MHz and thus reached ten times the performance of the Intel 8008. The processor was mainly used in traffic lights; It was far from being thought of using it in personal computers.

1976: The Intel 8085 flops

Although the 8085 was clocked at 5 MHz, the manufacturing technology was reduced from 6 to 3 microns and the number of transistors could be increased further to 6,500 the 8085 was not a success and could not establish itself in the market.
