Although it is the case that processor core-counts have risen in recent years, there are no hard or fast rules about how many cores an Intel Core i5 or i7 processor should have in it.

So, what is the difference between an Intel Core i3, i5, i7 and i9? What do vendors mean when they talk about generations of chip-sets?

Are there many differences between the i3, i5 & i7 mobile processors? I am looking at performance and battery life. Does a i7 chew through more power than a i5?

From a technical perspective, the main difference between an APU and a CPU is that the latter does not include any integrated graphics.
