Rick, here is a conclusion you might find interesting. Personally I don't think you can go wrong with either.
So, after performing many tests, which is the fastest CPU -- AMD's Athlon 64 or Intel's Pentium 4? The answer depends on which software you use: there is no clear winner here.
The Athlon 64 has an advantage with mainstream office and Internet applications, and 3D games. Meanwhile, the Pentium 4 can always score with optimised software -- particularly 3D and video rendering. The multitasking tests also show an advantage for Intel's Pentium 4.
The Athlon 64 has a clear advantage in terms of cost. Although AMD's and Intel's fastest chips are comparably priced, system costs are higher for Pentium 4-based PCs with DDR2 memory. The price difference between Athlon 3500+ and Pentium 4 550 systems is even larger, because the AMD chip costs $71 less than its Intel counterpart.
Post-purchase costs should not be ignored, either. A Pentium 4-based system uses 60 to 70 Watts more power when idling and up to 89 per cent more power relative to an Athlon 64 PC. For a household with a few computers, this may not add up to a significant cost saving, but for larger enterprises with several thousand PCs the sums will look completely different.
The Athlon also supports the NX feature, which offers protection from certain viruses in conjunction with Windows XP Service Pack 2. Intel has announced that the Pentium 4 is to support the NX feature later this year. The Athlon chips' 64-bit capability is currently no advantage, as 64-bit Windows XP isn't due to ship until 2005.
Cheers, Dr. Dave
