80486 was the microarchitecture for Intel's 80486 line of microprocessors as a successor to the 80386. Introduced in April of 89, 80486 was initially manufactured using 1 µm process (later 800 nm). For AMD, this microarchitecture was used for their Am486 and Am5x86 families. This architecture was superseded by Intel's P5 in 1992 and K5 in 1994.
