<< I see
(http://www.intel.com/eBusiness/products/ia64/overview/bm012101.htm#5)
that Itanium has the same SPECint as UltrasparcIII practically on the
same frequency. SPECfp is 2 times better, Unlike UltraSparcII, Itanium
is only the first implementation of IA64, I would say a test
implementation. E.g. Itanium does not support multiple
branches/prefetch although IA64 does.

I would be *extremely* suspicious of SPEC values in this context, they
are far too susceptible to fiddling.
