SuperPI
calculates the number PI to 1 Million digits in this raw number crunching
benchmark. The benchmark is fairly diverse and allows the user to change the
number of digits of PI that can be calculated from 16 Thousand to 32 Million.
The benchmark, which uses 19 iterations in the test, is set 1 Million digits.
Lower
numbers denote faster calculation times (seconds), and hence better
performance.

Super PI
apparently cares little for 64-bit operation or dual-core processors. It's a
pure number crunching benchmark and the Intel Pentium D 840 holds its own well.
At stock, the Intel dual-core CPU bests its single-core sibling, and when
overclocked it leads the field in this demanding test.
Pifast is a
small program that computes Pi to a set amount of decimal places and also
displays how long the calculation takes. This then gives us a basis for charting
the results.
Results are in seconds; lower results are better.

In the
second of our number-crunching tests, the Intel Pentium D 840 fares less well.
It fails to supercede its single-core cousin at stock speeds, and falls behind
the various AMD processors by five seconds even when overclocked. Again, this
benchmark seems ignorant of the benefits of dual-core and 64-bit operations.
