ALL ABOUT CPU's (Central Processing Unit)
Here are the things that deserve and need to consider when you want to choose a laptop CPU.

Clock Speed, Front Side Bus (FSB) and Chace
All CPUs have a clock speed, both in megahertz (MHz) or gigahertz (GHz), but the latter is the more common and most commonly found on modern laptops. In general, the greater clock speed, FSB and cache are owned by a CPU the better the computer performance you get.

Number of Core
There are two kinds, single core and multi core.
Single-core processor, there is only one CPU only, and of course he was not as tough martially inclined "unlike and multi-core processor. In the next generation emerged that combines Dual Core 2 processor to a separate physical package to produce a more powerful process.
Quad core, for which there are 4 processors in it but the laptop manufacturer to grow only these types of CPUs into a laptop-class specific, depending on the need for the use of the laptop itself by considering the power and long battery consumption, usually hell for gamers.
CPU Netbook or Nettop
Designed to netbook or nettop, Intel Atom processor in one, designed to meet the demand for lightweight computing, such as browse, check email, and chat. Currently Intel Atom present at speeds between 800 MHz to 2 GHz. My advice if you want to avoid buying a netbook processor with speeds below 1.6 GHz due to slow performance.

Ultrathin Notebook
New class of PC Ultrathin nih ... driven by Intel ULV (Ultra Low Voltage). This class includes CPU Celeron processor, Core 2 Solo, and Pentium. Chipset-chipset specializes in extending battery life in use.

Mainstream Notebook
If you want a notebook with more processing power, mainstream notebook can be a choice, because this notebook CPUs is a member of the class highend Intel Core2Duo. Tapi yach you can not find the body notebok with ULV-powered thin, but you still can play games and create an exciting multimedia content. But you also will get a system with long battery usage. Well if you need extra processing, I suggest you to select the CPU with a minimum clock speed of 2.4 GHz.

Hopefully the information I provided to be useful for you. Thanks
