These tests are (of course) bogus
EX & EP is a ridiculous comparison. Cache structures, cores, just about everything is different and integer sensitive workloads will fly on EP and do worse on EX. Where's the compare to the other 4 Socket E5-4600 EP's? Like the IBM x440 (http://www-01.ibm.com/common/ssi/cgi-bin/ssialias?infotype=AN&subtype=CA&htmlfid=897/ENUS112-099&appname=USN). So the net result is that HP is using an exceptionally defective method of comparison. Huh... where's the Itanium compares? <crickets>
