"The K5 was based upon an internal highly parallel RISC processor architecture with an x86 decoding front-end." https://en.wikipedia.org/wiki/AMD_K5 https://en.wikipedia.org/wiki/AMD_K5 This was before the NexGen acquisition, so the 29k would have been the obvious RISC. "AMD purchased NexGen when AMD's K5 chip failed to meet performance and sales expectations." https://en.wikipedia.org/wiki/NexGen https://en.wikipedia.org/wiki/NexGen
