T-Break has posted a comparison between Pentium 4 and Athlon 64

While AMD’s CPUs have had 64-bit support for quite some time, Intel just introduced them for their desktop PCs this week. Microsoft is slowly but surely working towards the 64-bit version of Windows XP which is currently in RC2 state meaning it is almost done. Now the Athlon64 has been benchmarked on the 64-bit XP quite a few times but we’re sure that lots of people are interested in finding out Intel’s performance.

This is exactly what we’ve done for this article. We’ve taken some of the benchmarks we commonly use in our CPU testing and ran them across Windows XP in 64 bit. Keep in mind that these are 32 bit apps that are running on 64 bit XP under WoW64. We have to wait for actual 64-bit apps to see if there is any noticeable difference between them and their 32-bit versions.
