I understand that the way their bus systems are make them faster than the old Core 2 Duo series. What I don't understand, and this may seem rather simple to some, is that when someone states the clock speed for one of these processors are they talking about the total clock speed of all of the cores of just the speed at which one core runs? E.g. 2.4GHz i3 dual core processor... does that mean a total processing power of 4.8Ghz or that each core runs at 1.2GHz?
Clock is shared, so each core clocks the specified frequency.
