This change in clock speed is very important for running any software on the computer or laptop.
The dual-core has lesser clock speed when compared to the core 2 duo. The lower the clock speed the higher will be the performance of the processors as well as the computer.So when the bus speed is high then the more data is moved and executed in the processor. The speed at which the data moves in a bus is called bus speed and in dual-core it is more than compared to the core 2 duo. During the processing, data is transferred or moved across the bus.In the dual-core, the pipeline storage is more than in the core 2 duo processor. Whenever there are instructions given to the processors, the instructions get accumulated in a pipeline and this is called the pipeline storage.Whereas in the core 2 duo processor the CPU speed is faster which makes the core 2 duo run faster. The dual-core processors the number of cycles that a CPU can execute a task in a second is low.Main Differences Between Dual Core and Core 2 Duo
