Repeat after me, there is no K9, there is only K10 now. A while back, circa Comdex 2003, there were some AMD roadmaps floating around showing K9 coming out in mid-2005. Now anyone with half a brain knows that that won't happen, the next generation core is not slated until mid-2006. What is this mystery core?
In the finest Intelesque naming traditions, the dual core K8 is now K9, and the next real core is K10. If the addition of SSE to the PII core rated an extra I, the addition of an extra K for another whole core is a forgivable PR gaffe.
