1. It looks like the 64 bit versions of Python for Windows are CPU
vendor specific, eg. it doesn't look like there's a single, universal
executable for Windows 64 bit platforms. Is this true?
It's true for ALL operating systems, not just Windows. The ia64 (Itanium)
and the amd64 are completely separate processors with VERY different
instruction sets.
Maybe I'm wrong, but I have the impression that Malcolm is a bit
confused about the different 64-bit processors from Intel and AMD. So,
to clear things up a bit:
- The Itanium (ia64) is a 64-bit processor made by Intel, mostly for use
in high-end systems (servers etc.) IIRC. It's instruction set is indeed
completely different from the i386 instruction set (though I think
there's an emulation mode)
- AMD64 (or x86-64 or x64 or EMT64 or Intel64) is a 64-bit instruction
set from AMD which is an extension to the i386 instruction set, and runs
32-bit (and 16-bit) i386-code natively. But, and this is important,
despite the name the instruction set is also used by Intel (though they
call it EMT64 and made a few minor changes).
If you have or buy a 64-bit computer, it almost certainly uses the AMD64
instruction set, even if it has an Intel CPU (if you have an Itanium or
other 64-bit CPU, I suppose you would know; it would not be something
you buy from the shelf in a regular computer store). So you almost
certainly need the AMD64 version of Python.
