If not then it is useless to say that things will change for chess software a lot when there is native good x86-64 compilers for opteron (and future intel x86-64 platforms which does *not* include that 3.06Ghz Xeon MP). Note that the 3.06Ghz Xeon MP you show there is about $5000 a piece. spending $16000 to get 4 of them is pretty expensive therefore. Also note that most of the benchmarks are not close to how chessprogs react onto extra registers and such. >the second graph on this page: > >http://www.anandtech.com/cpu/showdoc.html?i=1818&p=5 > >(general usage performance; business winstone 2002) > >and the 3rd graph on this page: > >http://www.xbitlabs.com/articles/cpu/display/opteron-1_19.html > >Performance: Office and Content Creation Applications > business winstone 2002 > > i have noted these bench marks correlate very well with chess benchmarks;based >on these the opteron does not seem much better than an athlon xp; infact one of >aaron's 2400 babies might thrash the opteron pretty badly; > >in all other tests the opteron is to put it mildly "pathetic" i doubt that >anyone will ever want to buy such a system esp when intel has come out with >this:http://www.gamepc.com/labs/view_content.asp?id=xeon3061MB&page=1
