I am not sure how important performance is for you, but here is
some anecdotal evidence:
A colleague just told me how he gets 150% faster performance on the
multicore AMD chipset compared to the latest Intel multicore for
his single precision floating point code. I am unfamiliar with the
various chip designs and can't comment on the details, but I suspect
that performance is dependent on the type of code you are running,
i.e., is it double or single precision, floating point, integer math,
in-cache, memory-bound, cpu-bound, etc. - lots of questions. I recommend
benchmarking your code before settling on an architecture.
