Bruno, you can make benchmarks say whatever you want - and this one seems to
be one of the worst distortions I've seen in a while.
I know from personal experience that this isn't even close. dual xeon
2.0Ghz/4GB is about the same performance as a quad 450Mhz E4500/4GB in
everything we're doing...
The TPC-C benchmarks (only official, impartial benchmarks I could find) are
even worse:
dual 3.6Ghz scored 63464
14 way 464Mhz E4500 scored 67103
Oracle has a word doc on their website talking about performance of a E4500 vs
a Dell box (http://download-west.oracle.com/owsf_2003/Oracleworld2003.doc)
where a quad xeon beats a quad E4500 by about 60% - and that was a quad
700Mhz P3 based Xeon...
Go search google for Xeon and E4500 and you'll see tons more of these
benchmarks - and they all tell the same story...
Peter.
