No. That is the point of this thread. The marketing name "Intel 64",
also known as "EM64T" *is* AMD64 aka x86-64. All modern Intel
Pentiums, Core series, and Xeons are x86-64. It is called AMD64 in
Debian because AMD invented that extension to x86; Intel copied it
when it turned out to be so successful.
IA64 (Intel Architecture 64, named long before the marketing name
"Intel 64" for x86-64) is the Itanium processor and is about as
different from anything x86 as it is possible to be. It is a VLIW
architecture, very unlike traditional CISC (x86, PDP-11, VAX, Moto
68k) or RISC (ARM, MIPS, POWER, SPARC). Itanium is a very expensive
chip that is used in very expensive servers and mainframe-type
computers. It is/was meant to compete with high-end modern SPARCs and
IBM POWER, and to some extent IBM zSeries/System Z, and it was a
replacement for HP's PA-RISC.
