Bad article: "There are multiple types of 64-bit processors – there are those based on the old x86 architectures (now known synonymously with 32-bit) which are basically 64-bit extensions, rather than native 64-bit processors, and then there are full 64-bit processors." -- [sic]. x86-64 architecture is a full native 64-bit architecture. Non-native would be something like using two DWORDs in software to emulate a 64-bit pointer -- which is not the case at all since x86-64 has native 64-bit pointers.
