This generational and chronological list of Intel processors attempts to present all of Intel's processors from the pioneering 4-bit 4004 (1971) to the present high-end offerings, which include the 64-bit Itanium 2 (2002), Intel Core 2, and Xeon 5100 and 7100 series processors (2006). Concise technical data are given for each product.


The 4-bit processors[edit]

Intel 4004[edit]

First microprocessor (single-chip IC processor)

MCS-4 Family:

Intel 4040[edit]

3000 Family[edit]

Intel D3002

Introduced in the third quarter of 1974, these components used bipolar Schottky transistors. Each component implemented two bits of a processor function; packages could be interconnected to build a processor with any desired word length. Members of the family:

Bus width 2*n bits data/address (depending on number n of slices used)

Intel 805xx product codes[edit]

Intel discontinued the use of part numbers such as 80486 in the marketing of mainstream x86-architecture microprocessors with the introduction of the Pentium brand in 1993. However, numerical codes, in the 805xx range, continued to be assigned to these processors for internal and part numbering uses. The following is a list of such product codes in numerical order:
