AMD Sempron 3000+ speed

the amd cpu tend to run at a lower frequency as you now know. im told that
regardless that amd actually runs faster than intel which is weird

Not wierd at all. AMD procs. tend to be more robust designs than Intel, so
they don't need high clock speeds to perform as much work as Intel procs.
do. It's like a V8 engine vs. an I4 engine . . . both are good designs, but
the I4 needs higher revs. to get the job done. The V8 can maintain
relatively low RPMs and still move the car quite nicely. -Dave
