first of all, Intel claims to have had the original idea of dual core 
which any educated hardware expert knows to be false.  AMD touted 
support for multiple cores months ahead of intel and it's apparent by 
the hyper transport technology white paper that AMD was planning this 
route when the Athlon XP was released long ago.  Intel only recently 
scrapped their processor roadmap.  rather than attempt to hit the 4GHz 
mark they re-wrote the roadmap, fabbed up a quick and dirty dual core 
solution and released it before AMD claiming that the idea was theirs... 
i hate that company...
