Dual Core Vs Single CoreBesides the obvious difference in the number of processors, there are many other differences between a single and dual core processors. A dual core processor is a computer with two separate cores on the same die. Each processor has its own cache and it is basically having two microprocessors instead of one.

It is a bit different from a single core traditional processor. The traditional CPU uses strings of information and it orders, executes and selectively stores it in its cache where it waits for a quick retrieval. In the case where data is needed that is outside the cache, the system retrieves it from random access memory or RAM or from any available storage devices.

Accessing these devices can significantly slow down performance to the allowed speed of storage device, RAM or the bus. Usually, this speed is far slower than the normal speed of the CPU. The situation slightly changes when multitasking is in question.

If a processor must execute more than one program, the performance will suffer because of the depleted CPU resources. Therefore, a dual core processor is far faster than a single core processor. It is due to its ability to handle more than one task with ease since it has more than one core.

Each core handles incoming data simultaneously, which largely improves its performance and efficiency. In a world of today, people need more computing power because almost everything they do, they do using the computers. This means that it is better to have a system with two and more cores than one.

More running applications equals more cores

If you want to run more applications at the same time, you will need more than one core for sure. However, if you feel a bit traditional and you still decide to go with a single core, here is a warm recommendation on what would be a perfect configuration for you. i7 single processor in a combination with fast DDR4 memory modules would be a good example. It is a known fact that a single i7 has a practical advantage over any dual core processor.
