The Am486 is a 80486-class family of computer processors that was produced by AMD in the 1990s. Intel beat AMD to market by nearly four years, but AMD priced its 40 MHz 486 at or below Intel's price for a 33 MHz chip, offering about 20% better performance for the same price.

The AMD Am5x86 was one of the fastest, and most universally compatible upgrade paths for users of 486 systems. Introduced in November 1995, the Am5x86 is an Enhanced Am486 processor with an internally set multiplier of 4, allowing it to run at 133 MHz on systems without official support for clock-multiplied DX2 or DX4 486 processors.

The Enhanced Am486®DX Microprocessor Family is an addition to the AMD E86 family of embedded micropro- cessors. This new family enhances system performance by incorporating a 16-Kbyte write-back cache to the ex- isting flexible clock control and enhanced SMM features of a …
