The configuration of a computer is a measure of the performance of a computer. Mainly by the CPU, graphics card, motherboard, memory, hard disk, monitor, chassis, optical drive, keyboard, mouse and cooling system to determine. Foreign laptop brands are HP, Apple, etc., domestic laptop brands are: Asus, Hong _, Shenzhou, etc. 1. CPU, this mainly depends on the frequency and L2 cache, L3 cache, the number of cores. The higher the frequency, the larger the L2 cache, the larger the L3 cache, the more cores. The faster the CPU, only the third level cache affects the response speed. Memory access speed depends on the interface, the number of particles how much with the storage size (including the interface of the memory, such as: SDRAM133, DDR333, DDR2-533, DDR2-800,DDR3-1333, DDR3-1600, DDR4-2133), in general, the bigger the memory, the better the ability to process data, and the speed of processing data depends mainly on the which type the memory belongs to (e.g. DDR doesn't process data as fast as DDR3).
