Succession
80486 K6

K5 was the microarchitecture for AMD's K5 line of microprocessors as a successor to the 80486. Launched in early 1996, the K5 microarchitecture was AMD's first x86 microarchitecture to be designed in-house from the ground up without licensing or reverse-engineering Intel's architectures. K5 was intended to serve as AMD's baseline for future x86 microarchitectures. K5 was superseded by K6 in 1997.
