Itanium may be a measly 18% faster in FP than a p4 1.7, but it is also 30% slower in integer. Who is going to buy an Itanium system when they can have a Xeon that goes nearly as fast for a fraction of the price?

And I don't consider the Itanium clock speed disadvantage to mean that it will become more competetive in the longer term. P4 was designed for high clock speed, Itanium for high IPC. Itanium will never clock as high as P4 on the same process.

It seems to me that compression and encryption are completely integer (non-floating
point) operations. The only real heavy users of floating point are structural analysis,
CFD and graphics, SGI customers' areas. Itanium sounds like the r8000 which had
strong floating point performance but dismal integer performance. The r8k really
was a flop.
