Or in this >case, four single-cores rather than 2 dual-cores. Surprisingly the benchmark appears better for 1 dual-core than 2 single core in this test : http://www.tomshardware.com/cpu/20051107/single_core_cpus_aint_dead_yet-10.html except for the momery transfert where the single is 2 times faster http://www.tomshardware.com/cpu/20051107/images/image029.gif It's a bit puzzling :-s > > >> >>furthermore: >>If from >>http://www.amd.com/us-en/Processors/ProductInformation/0,,30_118_8796_8800~97051,00.html >>we may conclude that a dual AMD Opteron processor gives about 86% additional >>power in comparison with single processors at the same speed, >>Diep has an even bigger advantage. >> >>Still, a thourough analysis using chess programs as benchmark >>on the actual machines is required to prove your statement. >>Evidently the tournament organisation does not have access >>to these machines, so it is beyond their(our) scope. >> >>Can anyone present real measurements? >> >>Theo
