But where you see a difference is when that piece of code is tailored to that processor. You can definitely also see a difference in math processing. I'll have to run some benchmarks. Probably be some time before I don't have my hands tied behind my back though.
Personal Opinion: My AMD Athlon X2 4400+ (2.4ghz) seems to be just slightly faster then my P4 3ghz (Prescott). It takes probably almost 20-30 more minutes to build clfs-sysroot (through xorg) on my P4. Bear in mind that the LFS build on the P4 is substantially older then the CLFS build on my AMD. > > -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
