K5 was a family of microprocessors designed by AMD and introduced in 1996. K5 models directly rivaled Intel's Pentium processors. These processors were based on AMD's K5 Microarchitecture which was their first x86 microarchitecture to be designed in-house from the ground up without licensing or reverse-engineering Intel's architectures.
Overview
K5 was a result of desperation and frustration with cloning and second-sourcing Intel-based x86 microprocessors. Rumors for the development of K5 dates back to mid-1993, however it was only officially announced in late 1994 with the goal of releasing the first batch of chips in in 1995. K5, which stands for Kryptonite 5, which as its name implied was an ambitious attempt by AMD to take on Intel (being Superman, metaphorically). The design suffered significant delays due to late problems with various x86 incompatibilities. The first few models were finally released in March of 1996.
The K5 Microarchitecture introduced many technical improvements over Intel's Pentium, although it did come a little short in terms of raw performance. Nevertheless the K5 became AMD's starting point for their future microarchitectures.
