Sorry, you are right. Dual Itanium2/1.3GHz/3Mb cache cost ~$7.5k http://www.smb.compaq.com/MiddleFrame.asp?page=config&ProductLineId=433&FamilyId=1431&BaseId=9079&oi=E9CED&BEID=19701&SBLID=&AirTime=False I cannot find its SpecFP Rate on SPEC web site, but dual Itanium2/1GHz/3Mb cache system has score 30.7, so 1.3GHz system's score should be something like 38-39. $7.5 / 38 == less than $200. Comparable not only to Opteron server (Itanium is slightly better), but to the workstation as well (Itanium is slightly worse). >But still, what software are you going to run on it other than an OS? You have C/C++/Fortran compiler, and most of FP applications need just recompilation. I worked with some ISPs (they reported bugs in our compiler), and there *are* some large CAD-like applications available on NT for Itanium. >I will admit, I like Opteron.

Tell >me, how many Microsoft applications are available for IPF natively? Most important *server* ones: NT and SQL Server.
