Both AMD and Intel make a variety of processors, each designed for a particular type of laptop and computing, and each with its own set of upsides and downsides. The processor is the brains of the computer. It's the most important chip in a notebook, and it has power-management features that extend battery life. Notebooks use a variety of processor types depending on their focus.
For example, AMD Athlon 64 generally delivers gaming performance superior to that of Intel's Pentium 4. Conversely, the Pentium 4 generally performs encoding tasks faster than the Athlon 64. Further complicating things, a laptop's other components, such as RAM, hard drive size and speed, and graphics chip, all contribute to its overall performance.
Still, the processor (the CPU, or central processing unit) is the brains of the computer and the most important chip in a notebook. Which CPU a laptop uses is a crucial element to consider when making a buying decision.
