The Intel 4004 is a 4-bit central processing unit (CPU) released by Intel Corporation in 1971. Sold for US$60 (equivalent to $470 in 2024 [ 2 ] ), it was the first commercially produced microprocessor , [ 3 ] and the first in a long line of Intel CPUs .
Intel Haswell Core i7-4771 CPU, sitting atop its original packaging that contains an OEM fan-cooled heatsink. This generational list of Intel processors attempts to present all of Intel's processors from the 4-bit 4004 (1971) to the present high-end offerings. Concise technical data is given for each product.
The Intel 4004 – a 4-bit CPU (central processing unit) on a single chip – was a member of a family of 4 custom chips designed for Busicom, a Japanese calculator manufacturer. The other members of the family (constituting the MCS-4 family) were: the 4001, a 2k-bit metal-mask programmable ROM with programmable input-output lines; the 4002, a ...

The 4-bit Intel 4004, released in 1971, was the first single-chip microprocessor. Modern microprocessors typically include on-chip cache memories . The number of transistors used for these cache memories typically far exceeds the number of transistors used to implement the logic of the microprocessor (that is, excluding the cache).
After the 4004, Intel designed the 8008 (architecture by Computer Terminal Corporation, design by Federico Faggin and Hal Feeney). Shima then joined Intel in 1972. [2] He was employed to implement the transistor-level logic of Intel's next microprocessor, which became the Intel 8080 (conception and architecture by Federico Faggin), released in ...
