Erm..... What the hell is Itanium lol? This is the first time I've heard of it. Is it some kind of laptop chip, or server chip? I thought Penryn\Nahalem was the next big thing =?

Intel's (other companies helped like HP) native 64bit chip for server/super computing, been around for a little while now.

I first heard about Itanium 8 years ago back in '99.
From what I understand EPIC IA64 is a very powerful architecture. It's downfall however, is that it doesn't natively support the more common x86 code.
Sure you can emulate but that makes for more bloat, inefficiency and general BS that people don't want to mess with (except for Intel).
Also, AMD is legally forbidden to copy the Itanium instruction set for it's chips.

The Itanium architecture is a native 64-bit architecture, it's not RISC or CISC, Intel call it EPIC; which is similar to VLIW.
Itanium is somewhat based on HP's PA-RISC. Intel and HP have cooperated on designing the Itanium architecture. The engineers that worked at HP have moved to Intel so it's pretty much a Intel Only project now. HP is the largest seller of Itanium based machines.
The architecture relies on good compilers, because the instructions are grouped so that they can be executed at the same time in parallel more effeciently than x86 CPU's out-of-order execution.
Itanium is good for crunching numbers and do scientific work. They are mainly used in high-end servers and super computers that rely heavily on floating point operations which is used in simulations.
Itanium was able to execute x86 code with a on-die emulator until rather recently, where Intel removed that part to save die space. x86 emulation is now done by user-mode software from within an operating system, such as Windows Server 2003 for Itanium 64. The emulation is quite slow, because you don't buy Itaniums to run x86 code.

I think Intel should stop the Itanium project and move on. Intel should invest their resources for designing dedicated GPU that has the ability to calculate other data besides graphics. Both nVidia and AMD/ATI GPU has like super computer speeds which can help in engineering or other scientific applications. nVidia's GeForce8 8800GTX or even better nVidia Telsa has a few hundred gigaflops which is a lot faster than the Itanium processor.
