A couple of weeks ago we looked at the Athlon64 FX-51 and how it compared in single channel mode to the Pentium 4, Athlon XP, Opteron and Athlon64. The result was that the AFX and p4 were the clear leaders however neither really established its dominance. So today we take a look at the 2 leaders and see if there is a clear winner when the Athlon64 FX moves into dual channel mode. We?ll also take a look at how well the FX-51 overclocks.
