2025年3月12日 · Am486 was a family of 32-bit 4th-generation x86 microprocessors introduced by AMD in 1993. Am486 chips were compatible with Intel 's 80486 and offered equivalent performance for cheaper prices. Just like AMD's Am386, Am486 was also delayed after expensive and lengthy litigation with Intel.

Enhanced Am486, built around the standard AMD 486 core, incorporated write-back cache and enhanced power management features. These characteristics made them a good choice for reduced power consumption desktop systems and for the portable market segment.

First we tested the Dhrystone performance of all processors. Reference is always the TX486DLC processor: UMC tops Intel, so UMC must be better than AMD.
