The list price for our 2 X >2.0Ghz Opteron system is around $6000. For the two-way 1.5Ghz Madison system >that gets 30 SPEC FP rate it's $26,000. Here is dual Itanium2/1.5GHz/6Mb L3 for ~$15k: http://www.smb.compaq.com/MiddleFrame.asp?page=config&ProductLineId=433&FamilyId=1431&BaseId=9443&oi=E9CED&BEID=19701&SBLID=&AirTime=False And I believe exactly such system (zx6000 with dual Itanium2/1.5GHz/6Mb L3) has Spec FP rate of 42: http://www.spec.org/cpu2000/results/res2003q3/cpu2000-20030630-02327.html Thanks, Eugene >>For integer performance story is different, but that thread was about FP >>performance, right? :-) >> >>Thanks, >>Eugene
