Actually, dual-core means they have two physical cores in one package. 
Two logical cores = hyperthreading. ;P

On that note, you want the AMD dual cores as well, because they are 
much better designed (they have the crossbar architecture all ready to 
drop in additional cores, whereas the current Intel dual-core are 
really ugly hacks and perform terribly compared to the AMD ones)
