This isn't completely correct. There is actually an ia64 architecture, before 
Intel was ready to give up the "who dictates the PC 64bit architecture" 
battle. There's a handful of CPU's who use that instruction set, but later 
Intel switched to supporting AMD's instruction set and thus the PC 64 bit 
architecture now is amd64.

It'll be fun to see people asking in a few years why Oracle processors are 
called "sparc64"...
