latest SPEC benchmark results

[Przemek Klosowski]

I have been looking at the relative speeds of CPUs of different types
(Pentium 4/Xeon/Athlon/Opteron/others). The obvious choice for a
general benchmark is the SPECmark; however, SPEC doesn't distill their
data, so I sat down and compiled this list of top SPEC Int and FP
performers, as of Nov 2003. It's interesting that Athlon FX at 2.2GHz
even competes with address@hidden in general computing tasks. Funny also
how Itanium excells for floating point but is way in the back for
generic integer computing.

Disclaimer: specmark benchmarks are a mix of various types of
computation, so they are somehow reperesentative of typical system
speeds, but of course YMMV. This is just for general orientation where
things stand. Since we have been discussing performance recently, I
present it here for your orientation and education.
