Actually, I'm not sure how much I do trust these results after all. Are you getting consistent output for the memory tests? Doing some testing on arcem on OSX just now (2.8GHz, OSX 8, XCode 4.4) my Main memory write varies anywhere from 372 to 481 MB/sec and cached stuff varies even more... from 2.8 to 5.46 GB/sec ! The dhrystone/whetstone figures are fairly consistent though, and seem to vary in line with the reported CPU speed, which wanders by about 5MHz from 134 to 139MHz.
