For years, the Sunnyvale, Calif.-based company designated its chip generations by the letter K. The company sold K-6 chips in the late ’90s, and the Athlon and Opteron were brand names for, respectively, the K7 and K8 generations of processors. AMD’s K was a counterpart to Intel’s P designation for chip families such as the P5 (the first Pentium) and the P6, which included both the Pentium II and III.
