amd 64 is just memory controler a 486 had 64 bit memory bus
but amd64 is half 64 and half 32bit so it can exucute symtaniusly i have owned intel and amd i love my amd, cause it is always faster and most benchmarks can prove that
tomshardware is anti amd
gotta have it to know
but i dont think i will ever go intel agin, because there sluggish
where talking about desktop processers here
amd64 is cisc and itanium is risc so there both officaly 64bit archatechers
theres no such thing as 64 or 32bit archtecher anyway
theres cores wich is the archtecher thats just mmx simd instructions memory controller that make up any archtecher, but theres no bits to it
