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 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 …

The Enhanced Am486 microprocessor family is an ad-dition to the Am486 microprocessor family of products. The new family enhances system performance by inco r-porating a write-back cache implementation, flexible clock control, and enhanced SMM. Table 1 shows avai l-able processors in the Enhanced Am486 microproce s-sor family.

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.

Am486®DX2 High-Performance, Clock-Doubled, 32-Bit Microprocessor ~ Advanced Micro Devices The following should be used as additional information to corresponding sections of the current data sheet (order# 17914). The Am486DX2 microprocessor has been extended to include 66 MHz. DISTINCTIVE CHARACTERISTICS

Am486是AMD最后一款克隆Intel产品的处理器，包括两个不同的版本，一个的微码为Intel，另一个为AMD。 AMD 486处理器中其中有一款市场型号为AMD 5x86，该处理器采用4x倍频，主频为133 MHz，支持486 主板 ，性能与Pentium 75相仿。

Using AMD’s speed-multiplying technology, the Am486DX4 CPU and cache operate two to three times faster than the external memory bus. It is manufactured using AMD’s new 3.3-V CMOS process technology to consume about 2.6 watts of power at 100 MHz or 3.2 watts at 120 MHz.
