The P5N32 wins by a tiny 0.3% margin, which is clearly well within experimental error; and the PF22 had a strangely low memory read rate for floating point reads. As our PF22 article showed, once we overclocked that board the anomaly went away.

WinRAR provides an excellent mixed processor speed and memory bandwidth test; and it seems to place roughly equal weight in processor speed and memory bandwidth improvements. The P5WD2 won over the P5N32 by a tiny 0.6% margin which is well within experimental error, however the PF22 lagged far behind.
