How much faster is a quad-core processor a dual core?

Comparing for example, an Intel Core 2 Quad 2.00 GHz and an Intel Core 2 Duo 2.00 GHz, the pursuit to be twice as fast or slightly faster?

Quad-Core CPUs are relatively new on the scene and have not take more than two T-core processors is very easy to understand that with a quad core CPU you generally will run faster than a single core or double. So why not taking the quad core market yet? Simply because they do not always increase performance significantly enough need four cores, because the performance of a quad-core CPU depends on the programs implemented and the algorithms used in these programs. A quad-core CPU does not always run four times faster than a single CPU at heart. When running simple programs, most people, you not see the need for a quad core. But if you play the latest games or run intensive applications multithreaded then you will have the power of four cores to succeed. Hope this helps
