Since the emergence of laptop computers, they have been loved by many people because they are lightweight and easy to carry. When buying a laptop, most people look at their budget and then look at what laptops are available at the right price. Then I went to the store to buy it, listened to the introduction of the shopping guide, and bought the computer. Most people don't know how to look at the configuration of a laptop, and there are indeed many parameters. Today, the editor will take a look at the important configurations you should look for when buying a laptop.
1. CPU, this mainly depends on the frequency and the second-level cache. The higher the frequency, the larger the second-level cache, and the faster the speed. In the future, the CPU will have three-level cache and four-level cache. Level caching, etc., all affect response speed.
2. Memory, the access speed of memory depends on the interface, the number of particles and the storage size (including the memory interface, such as: SDRAM133, DDR233, DDR2-533, DDR3-800), generally speaking , the larger the memory, the stronger the data processing ability and the faster the speed.
3. The motherboard is mainly the processing chip. For example, the notebook i965 chip has stronger processing power than the i945 chip, and the i945 chip has a stronger data processing capacity than the i910 chip, and so on.
4. Hard disk. Hard disk is less considered in daily use, but it also has some impact. First, the speed of the hard disk (divided into: high-speed hard disk and low-speed hard disk, High-speed hard drives are generally used in large servers, such as: 10,000 rpm, 15,000 rpm; low-speed hard drives are used in general computers, including laptops). Desktop computers generally use 7,200 rpm, and notebook computers generally use 5,400 rpm. This is mainly due to consideration of performance. consumption and heat dissipation. The speed of the hard disk is different due to different interfaces. Generally speaking, it is divided into IDE and SATA (which is what we often call the serial port).Interface: Most of the early hard drives had IDE interfaces. In comparison, the access speed was slower than that of SATA interfaces. Hard disks have also developed with the market in recent years, and the cache has increased from 2M to 8M or larger. Just like a CPU, the larger the cache, the faster the speed.
5. Graphics card: This is directly related to the response speed of running very large program software, such as running CAD2007, 3DStudio, 3DMAX and other graphics software. In addition to the distinction at the hardware level, graphics cards also have "shared graphics memory" technology. Different from the general built-in graphics memory chips, this "shared graphics memory" technology requires the graphics memory to be read from the memory to handle the needs of the corresponding program. Or some people call it: dynamic video memory. This technology is more commonly used in laptops.
When buying a laptop, you mainly need to look at these configuration parameters. These parameters determine the speed of the computer and whether it is smooth and easy to use. If you have friends who need to buy a laptop, you can research some specific configurations in advance and the configurations of laptops in the same price range, which will allow you to buy a more suitable and easy-to-use laptop. The editor recommends buying a laptop. Although it only costs a few thousand yuan, it is still better to shop around.
