Dothan is a 32 bit processor core lacking Montecito's
RAS, multiprocessing and multithreading capabilities,
and 4 DP FLOP/cycle FPU. AFAIK the Montecito CPU
has x86 compatibility logic in hardware. Build a Dothan
with ~300 SPECint2k IA64 compatbility logic and then
compare die size. ;-)

I can turn that around and ask if IA32 is really needed.
ARM is 32 bits, outsells x86 by 4 or 5 to 1, and is less
expensive/burns less power in equivalent technology.

But different architectures/implementations excel at
different tasks.
