The SPEED of the core processing is not a cumulative effect...
1.2 ghz is just that. 1.2 million/million instructions per cycle!
A PROCESSOR performs a simple binary function which is to operate a switch which will be either on or off, or a 1 or a zero. The processor is measured in how many transistors it has which can perform that on/off in how many times per second, hence it's speed. Overall, they keep making chips smaller and quicker, allowing the compact placement of now 2 processors or cores within the space of a single chip. The DUAL core represents that their are TWO distinctive operations per cycle, within ONE chip. So now you have twice the computations being performed in the same cycle. Meaning the single processing chip can handle 1.2 million/million switches (transistors = on/off = binary - 1/0) per cycle then times that by two. A very powerful leap over a single core chip.
Not half that x2 to make one...
Lol... maybe a bad translation, but one I hope might help clarify what the chip is doing.

If it's truly "COMMON" sense, then why do so few possess it?
