A processor is the most important component of a computer system as it manipulates data and controls the execution of program instructions. The main factors while buying a processor are speed and the type of processor. Speed is an important characteristic that affects the overall performance of your system. Higher the speed, faster is the performance of your system. Our processors come in different types from Intel and . Please check the processor column in the tech specs sections for determining the processor type of this product.
