Comparing the SpecInt results from a system using an Intel compiler and one using a HP compiler shows how much of Spec is a compiler benchmark rather than a CPU benchmark. Surprisingly, despite the reputation of Intel's compiler team, it seems HP make a better Itanium compiler than Intel.

Looked at another way, it says you can save yourself the cost of at least one CPU grade by using the better compiler. It's two grades by simple frequency scaling, but the differences between 4MB and 6MB L3 cache look like they're worth about 10% on SpecInt on their own, compare with above Intel result.

Itanium in general is giving some very interesting cross-platform comparisons, since it's supported by several competing hardware and software vendors.
