• The first AMD Opteron processor (single core) is
  released on April 22, 2003.
• Opteron is AMD server and workstation processor
  line, and was the first processor to implement
  the AMD64 instruction set architecture

• AMD launched its Third-Generation Quad-core
  Opteron implementing K10 architecture on
  September 10, 2007
• The new K10 architecture is based on the K8
  (a.k.a. AMD64) architecture with some
  enhancements.
• AMD never released an architecture called K9,
  from K8 they jumped to K10.
