These processors came with all the features of the {{amd|Am486#Enhanced Am486|Enhanced Am486s}} but had the highest clock speed available. These chips, which ended up performing comparable and on occasion better than the {{intel|Pentium}}-75, became the de-facto upgrade for users with existing 486-based systems. This family solidified AMD position as the official Intel competition. |

Has a sort of a stopgap between the {{amd|Am486}} and the yet-to-be-released K5-based processors, AMD released the Am5x86 family. The name came about due to competitors selling 5th generation-based [[x86]] processors (e.g. {{Cyrix|Cyrix 5x86}}) - people were more likely to buy a system with "5" vs "4". AMD took this opportunity to utilize their latest technology and release a final, highest clocked 486 chip for much lower price than their competitor's latest chips. This is very similar to what they had done with their highly successful {{amd|Am386/Am386DX-40|40 MHz}} version of their {{amd|Am386}} family. Later, strong sales of Am5x86 played a crucial role in keeping AMD's profitability while their {{\\|microarchitectures/k5|K5}} microarchitecture was experiencing severe delays. AMD continued to sell Am5x86 chips for personal computers until 1999 and for embedded systems well into the 2000s. |
