My recollection was that components (there are a number of support chips needed for each Itanium, not just a north bridge and a south bridge. Q1000 prices worked out to well over $1,000 per CPU. OEMs usually double prices (at least). The OEM BOM cost difference between Itanium and Opteron 4-way, for motherboard and CPUs, will likely be $10,000 vs. $3,000. For 8-way, $25,000 vs. $6,000. Similarly configured (with the same hot swap disk arrays and memory) 8-way Opterons will likely sell for less than 4-way Itaniums. 4-way Opteron will be much cheaper to produce than 4-way Itanium. The chipset docs are here: ftp://download.intel.com/design/Itanium/Downloads/24870301.pdf Look at pages 12 and 13 of the pdf. Besides the 4 Itaniums, it appears that in Itanium motherboard will require a SAC, SDC, GXB, PXB, PID, IFB, and WXB chip. Multiple MAC, MDC, and FWH chips are also required. Intel has invested design time, development time, and FAB time for each of these specialized components of the Itanium chipset. They've had to develop masks etc. for each one. The volume of each of these chips won't be very big for some time, depending on whether or not they intend to recover costs for the next few generation of Itanium, the components for an Itanium motherboard will be quite expensive. Opteron will also require several chips, but fewer, and simpler chips than Itanium. Opteron isn't just a less expensive chip to build and write software for, it's a less expensive hardware platform - which should make it practical for higher volume, low end servers, as well as high end servers.
