Who is the zealots, you don't even click on shintai link. So as you're too lazy.
AMD benchmark configuration information for such kind of comparison:

# 2 Xeon 5355 processors in FSC Primergy RX300 S3, 16GB memory, 73GB SAS disk drive, Microsoft Windows®Server 2003 x64 Enterprise http://www.spec.org/cpu2006/results/...219-00524.html

And again in the barcelona simulated comparison, if you take about 3s to read the footnote:
http://multicore.amd.com/GetFile.asp...trate_040207v2
you read:
"competitive benchmark results stated above reflect results published on www.spec.org as of april 16. 2007. The comparison presented above is based on the best performing blabla... "

Best performing... Nowhere best performing using this and that blabla, just best performing, they don't care of os or compiler, they only take the "best performing"
