wbmw,

Re: Intel Corporation demonstrated its latest version of the Intel® VTune(TM) Performance Analyzer with additional features that make application performance tuning easier and more efficient for Microsoft Visual Studio(1) .NET(1) developers so that their applications can run at the highest levels of performance on Intel-based platforms.

You are probably aware of that the type of applications that we will be seeing more of (.NET/CLR, Java) are the types of apps that run badly on P4, well on Athlon and Piii. And these apps will be the biggest nail in the coffin of Itanium, since the performance will be horrible.

In short, Intel has concentrated on improving performance on code that has a lot of parallelism, repetition, while the performance on ad-hoc (for lack of better term) code suffered. Now add to it Itanium's reliance on optimization by the compiler, while these emerging technologies more and more depend on Just In Time compilaton, you can imagine Itanium engineers slapping their forehead and saying "Oh Sh**!"

I guess it can be explained by the fact that Itanium development has started a decade ago, and the architects could not have predicted that the software will move in the opposite direction from what they thought.
