I know what you are trying to prove, and it is that the cost per Power4 system to IBM is not inherently more expensive than the cost per Itanium system to IBM. This is only true if you are considering the fixed costs of the componentry, either as it rolls of the assembly line, or as it's purchased directly from vendors such as Intel. However, this is not entirely correct, since there are additional costs built in to every Power4 system that IBM makes. Those costs have to do with the research and development of the CPU and system itself. For Itanium, Intel has done most of the work. If IBM wants to differentiate the platform, they can invest in that, but if they wanted, Intel pretty much already has everything at their disposal to buy and resell a nearly complete Itanium system (or at least the processor, platform, and enclosure). For Power4, that is all up to IBM to invest the time and money into creating the processor, platform, and enclosure. Not only that, but there is additional investments needed for tools, an OS, a compiler, etc. All these costs are not trivial, so you must include them into the "per system" cost comparison between an Itanium and Power4 system for IBM to sell. The is the same reason why Compaq gave up the Alpha and HP gave up the PA-RISC. Both architectures cost those companies more to keep up than to just buy a common platform from Intel. A couple years down the road, and we'll know whether that was a good business decision. Right now, your guess is no better than mine. wanna_bmw
