In 21st Century people are more into Computers and Laptops. Buying a system is now easy as you have many options as well as online and offline stores which provide you best systems and laptops.
Before buying people only think what is the need such as that if they need gaming laptop or system or a office based type system or laptop.
Well I will say that, that's one of the main factor you think before you buy a laptop or system. On other hand you should also know that what is the specs of that system which you are willing to go for.
Today two types of processors are really in demand:-
1) AMD Quad Core
2) Intel Dual Core
Let's talk about the difference and performance of these two processor:
1) AMD Quad Core:- A multi-core processor is a processing system composed of two or more independent cores. It can be described as an integrated circuit to which two or more individual processors (called cores in this sense) have been attached.
A type of multi-core technology that includes two separate dual-core dies, where dial-core means a CPU that includes two complete execution cores per physical processor), installed together in one CPU package. In this set-up cores 1 and 2 would share a memory cache, as would cores 3 and 4. If core 1 or 2 needs to communicate with 3 or 4, it is an external communication, usually via the front-side bus. Both Intel and AMD have introduced quad-core processors, starting with Intel in late 2006.
Inetl Dual Core:- Dual-processor (DP) systems are those that contains two separate physical computer processors in the same chassis. In dual-processor systems, the two processors can either be located on the same motherboard or on separate boards. In a dual-core configuration, an integrated circuit (IC) contains two complete computer processors. Usually, the two identical processors are manufactured so they reside side-by-side on the same die, each with its own path to the system front-side bus.
