Dualcore = 2 processors machine. So a dualcore has 2 real processors (their just packaged into one container) on the machine unlike a HT.
the fact that the cpu is packeged inside one core does not change the fact. Infact its impossible for the computer to see any difference. Hyperthereading is a different thing here.
Pixar techs said they could try to guess to guess wtheter a dualcore is in place but they still havent decided whethere or not to consider a dualcore a real diual or a 1 proc machine.
