What is the advantage in many cores in the microprocessor?

Answer 1

Modern integrated circuit technology is reaching limits of small size and high speed that are getting harder and harder to overcome. However putting multiple processors on one chip allows microprocessor manufacturers to work around this by letting the operating system assign independent processes to different processor cores, converting a serial problem into a parallel one. The speed of an n core processor approaches asymptotically the speed of one processor running n times as fast. At a far cheaper price than that hypothetical high speed uniprocessor would cost with current technology.

Answer 2

Having multiple processor cores in your computer can help relieve some of the computing stress from a processor and equally distribute it among others, thereby increasing processor efficiency and making your computer much faster.
