Generic PC/AT 486 (c) 1989 None

The Intel 80486, also known as the i486 or 486, is a higher performance follow-up to the Intel 80386 microprocessor.

- TRIVIA -

The 80486 was announced at Spring Comdex in April 1989. At the announcement, Intel stated that samples would be available in the third quarter of 1989 and production quantities would ship in the fourth quarter of 1989.

The 80486 was the first tightly pipelined x86 design as well as the first x86 chip to use more than a million transistors, due to a large on-chip cache and an integrated floating-point unit. It represents a fourth generation of binary compatible CPUs since the original 8086 of 1978.
