The article is negative about the iTanium, but my colleagues in high performance computing tell me that this is a *very* capable cpu which is going head to head with the Power4. I think Intel has stumbled: http://www.theregister.co.uk/content/61/28894.html I think I'd have to agree with

POWER4 is clearly better positioned at present. This is arguable. For the small class of problem where 64-bit system like an Itanium is really the only option, IA64 does well, although the PowerPC does about equally well (modulo operating system availability, which is getting better with

AMD may steal some of Intels play because their 64 bit chip will also be backwards compatible. Everyone associates Intel with cheap commodity processing. Itanium does not fit that bill. They will need to do some marketing to inform corporate America why they should spend more money on a

That depends on what you mean by better. Leaving out backwards compatibility makes for a cleaner design at first, but then the new design becomes the legacy over time, and the clean design becomes yet another cluttered design. My opinion is that Intel is going to have a hard time getting

This is not the real performance of Linux under VM. This is the real performance of S/390 processors in general. S/390 processors are _slow_ compared to the newer generations of Intel hardware. Don't use them for CPU intensive tasks if you can avoid it. Compressing and decompressing data are
