AMD vs Intel: A Linux Bout
 

AnandTech puts the latest and greatest AMD and Intel CPUs, including 32-bit and 64-bit versions, to the test in their first ever "Linux Desktop CPU Roundup" to see which performs the best in various Linux applications including database, compiling, rendering, encryption, and more. They suggest the Athlon 64 3500+ over the P4 560 for "balancing price and performance". Very informative

Wow, the improvement from 32 to 64bit is simply amazing!

Very detail comparison; not to knock anything down, as I'm sure 64-bit Prescott version will arrive soon enough to meet WindowXP official release. AMD is more innovatiive than Intel; Intel is more business savy than AMD. If this formula would hold true, we will soon find out.
