Haiku OS Ported To Intel 64-Bit Architecture 101
An anonymous reader writes "The BeOS-compatible Haiku OS operating system has been ported to x86_64. As part of the Google Summer of Code, a student made a 64-bit port of the kernel and user-space and it's now working. However, not all of the BeOS apps and drivers are yet working in 64-bit mode."

The correct term for x86_64 is AMD64, not "Intel 64-bit architecture". AMD developed it, and licenses the patent to Intel. Intel64 is Itanium, to which Haiku has NOT been ported.

Summary got it wrong, think the correct term is AMD64.

Yes.
Intel64 is Itanium,
No. IA-64 was Itanium, but that architecture (which I think started out as an HP architecture) is now just called the Itanium architecture [intel.com]. "Intel64" is Intel's name for the 64-bit architecture as originally defined by AMD, modulo some differences [wikipedia.org] and modulo Intel and AMD going their own and subsequently modified by both parties with different flavors of SSE4 [wikipedia.org].
to which Haiku has NOT been ported.
Haiku was not ported to IA-64/Itanium. It was ported to whatever you want to call the 64-bit x86 architecture (I prefer x86-64, with my second choice being AMD64, although I guess if you want to include Intel's version of SSE4 rather than AMD's version, that's "Intel64").

x64 is misleading. The x86_64 still uses the underlying architecture and instruction set of the original Intel 8086. [wikipedia.org]. Changing the name to x64 would imply the instruction set is different from that of x86 - and while the instruction set has been extended it still (as far as I know) still support the instructions designed in the 70s.
I personally find x86_64 the most descriptive designation for a 64-bit x86-processor.
