This test, provided by the University of Oklahoma State's CASE Lab, is an excellent tool for representing common computational fluid dynamic simulators. It's also an example of pure floating point math abilities. The factory overclocked Soyo wins this test, with the other Athlon64 boards all clustered together, and the P4 left in their collective dust. Among the non-cheating set, the DFI sets the mark. More performance is available, since I ripped off constant 190 second runs after dropping the timings down to the floor in the bios. The other boards didn't offer such comprehensive tweaking, and those that came close (like the AOpen) weren't as stable with those same tight timings.
This is a test to see which setup can calculate one million digits of pi the quickest. Perhaps unsurprisingly, all 6 test subjects are clustered together. It would appear AMD got their performance rating correct, at least in regards to this benchmark.
