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 are better

Super Pi completes the standard 1 million digit test
slightly faster in a WindowsXP x64 Edition environment than it does in 32-bit,
but it's nice to see that the overclocking results from both platforms are
similar.

Pifast is
a small program that computes Pi to a set amount of decimal places and also
display's how long it takes. Since it tells you how long it takes this then
gives us a basis for charting the results giving a performance indicator for new
and old technology at a glace. Lower numbers are better.

piFast is another number crunching benchmark, and here
we see similar results for both 32-bit and 64-bit operating systems. Looks like
a faster processor equals better performance in both WindowsXP and WindowsXP x64
Edition.

I was
certainly surprised to see the multimedia benchmark numbers. While the integer
portion of the test is much lower than expected on WindowsXP x64 Edition, the
floating point section is higher. CPU benchmark numbers are similar as are
memory bandwidth scores. This version of SiSoft Sandra is compatible with both
32-bit and 64-bit Windows OSes.
