Why Dual Core

Some of you who are either buying a new PC or upgrading may be thinking or rationalisation of why to go in for Dual Core. There are some solid reasons for it. It increases performance by 40% compared to PIV and also it is more energy efficient compared to other PC's. That means less electricity bills, great news . Also Dual Core supports Thread Level Parallelism or True Multithreading. Its a technique to increase performance where as different threads carrying out processing of different parts of a program will be execute parallely in different CPU's. In a single core CPU time sharing is used for multithreading which is not a very efficient process. Intel is developing a Quad core and also working on a 80 core processor. More cores can be used for specific purposes like a graphics processor with onboard memory for better rendition of graphics.
