It is amazing to think that the Athlon64 X2 processors are now 2 years old while the original Athlon64 architecture is 4 years old. For so many years the Athlon64 processors made Intel’s numerous versions of the Pentium 4 and Pentium D processors look somewhat silly. Only in the last 7 months or so has Intel been able to take the performance crown from AMD. Of course, to do so they had to completely redesign the Core 2 architecture from the ground up and while the result is incredibly impressive, it hardly makes the existing AMD processors look silly.
