One additional thing to keep in mind is that the atom cpu's are made for low 
power consumption and not optimized for performance in scientific computing. 
So I simply think an atom cannot compete with a sempron, but I do not know 
about  concrete benchmarks for that.
The second thing is that you will not have any benefit from the dual core as 
long as you do not use explicit parallelization in your script to make use of 
the two processor cores. So it is very likely that you only used one of the 
cores.
I don't think it is a 32 vs 64 bit issue.
