The AMD SMP chipset has something which alpha processors has too. it can get/write words out of L2 cache from other processor, without needing to wait to read/write to main memory. The intel can't do this. It doesn't have the master/slave idea from the alpha. Also when running SMP the amd's profit more from their L1 cache than the intel does, though this is less important than the alpha feature the K7 has for SMP behaviour. So even if it is *close* to each other. When you start running the things SMP, then the P4 is history. > >looking at specint2000, more precisely > >(AMD Athlon (TM) XP 2100+ ) >http://www.spec.org/osg/cpu2000/results/res2002q2/cpu2000-20020422-01326.html > >(2.53 GHz, Pentium 4 processor) >http://www.spec.org/osg/cpu2000/results/res2002q2/cpu2000-20020506-01357.html > >the crafty bench is 97,9 secs for AMD and 106 for Intel. > >So crafty on AMD seems faster there .. what I'm overlooking? > >glm
