While it is a 'true' 64-bit processor, it still does not have a RISC-based 
isa.  It remains a CISC isa.  See: http://sandpile.org/aa64/index.htm

(There are many definitions for processor width, so 'true' is subjective. But 
the x86_64 probably satisfies it in most of the ways you could define it.)
