Why are Intel's core 2 duo processors more expensive than others but their ghz are lower than cheaper models

Answer 1

Ghz is not everything. The Ghz tells you how quickly the clock cycles are on a computer. However there is another aspect, called Instructions Per Cycle (IPC). This is how many instructions are processed on each one of those clock cycles. The Core 2 Duos have a much higher IPC than the old Pentium Ds or Pentium 4s do, meaning that despite the fact the clock cycles on them are slower, they processes many more instructions each time, resulting in it being overall faster. Add in the fact that they also have a faster FSB and more cache, and they end up being much better.

Answer 2

its like having 2 processors in the pc. Although you have less speed, you are doubling up on processing power.

think of it like having 1 really strong guy trying to lift a fridge himself VS 1 normal guys lifting the same fridge. it'll be easier for the 2 guys cuz the weight is distributed evenly

Answer 3

good question, it's because there are two processors, they have a combined power...
