a computer is not a machine that does computing. it is a primarily a machine that moves information around, and occasionally performs computation on it. as such, a quad core will saturday the processor - memory bandwidth much sooner than a dual core chip will, which stalls the pipeline. couple that with that four cores will abuse the cache much more than two will and you have a recipe for slowdown.
