As a CPU, the Atom is basically the brains of your computer. Everything that goes on in your computer has to go through the CPU. If you don't have enough power in your CPU, any software you have for your computer or device will run slower or improperly.
The Intel Atom is perfect for smartphones, netbooks and entry-level desktops. With its efficient integration of graphics and memory to the processor, it has multiple voltage and frequency operating points, which results in power reduction and improved performance. It is also inexpensive.
Intel offers a line of Atom processors with varying wattage, cores/threads and prices, depending on your computer needs.
