Different computer processors meet different computing needs.
How well a system runs is largely dependent on the processor it is using. Companies such as Intel and AMD produce differently powered -- and therefore differently priced -- processors, depending on the user's computing needs.
Intel Centrino
The Intel Centrino processor is designed as a budget-level processor family for laptops. They have less computing power than other processors, but are more energy efficient and allow a longer battery life.
Core 2 Duo
Intel Core 2 Duo processors have two processor cores. As of 2010, the Core 2 Duo had clock speeds up to 3.33 GHz, 6 MB of cache memory and a bus speed of 1,333 MHz.
AMD
AMD is Intel's rival processor manufacturer. They produce a number of processors, including their budget level Sempron processor, the rival of Intel's budget level Celeron processor, and the Athalon II X2, the rival of Intel's Core 2 Duo processor. The Athalon II X2 has two processing cores, clock speeds up to 3.3 GHz and 2 MB of cache memory.
