>From the current set of Intel docs:

"IA-32" is the traditional 32-bit i386 architecture.

"Intel 64" is the 64-bit x86-64 architecture.

The title of the arch manuals is:

"Intel(r) 64 and IA-32 Architectures Software Developer's Manual"

"Intel Itanium" is current name the 64-bit Itanium architecture.  Prior naming had IA-64 back when Intel thought that Itanium would be the 64-bit system of the future before AMD came along and pounded 64-bit features into the i386 architecture.  That IA-64 and IA64 have carried over in various pieces of software and documentation.  There was also IPF (Itanium Processor Family) as well.  And then HP made it more confusing with inventing the Integrity branding which at exclusively Itanium at the start but now includes "Intel 64" systems as well.
