1. Hard drive capacity: As the data storage of the computer system, capacity is the most important parameter of the hard drive, mainly considering the hard drive capacity and speed. , the mainstream ones on the market are 500 and 1T capacity, 5400 speed and 7200 speed. As of February 2023, the graphics card with the highest computing power is the RTX4090 graphics card, which is the highest configuration graphics card.
2. CPU: A laptop with excellent performance must be equipped with an excellent CPU. The CPU controls the flow of information in the computer and collaboratively processes most of the data in the computer. It can be said to be the core of the notebook.
3. The laptop configuration list usually includes processor, memory, storage, graphics card, and screen. Processor The processor is an important part of the computer and affects the overall performance of the computer. The main parameters of the processor include model, number of cores, main frequency, etc.
The following configurations: (1)CPU: determines the running speed, such as Celeron D66G, where "66G" refers to its computing speed, but here The unit "G" is different from the "G" of the hard disk. It is not the size. The "G" of the CPU is "GHZ" which is the frequency, which means it can perform 66G operations per second.
If users often travel on business, it is recommended to choose some ultra-thin and ultra-light notebooks with screens between 12 inches and 13 inches. If the user is sitting in an office, it may be better to choose a larger size so that it looks more comfortable.
Mainly depends on the configuration of the four components of the computer: CPU (Central Processing Unit): All operations of the computer are controlled by the CPU, and the performance indicators of the CPU directly determine the performance indicators of the system. Graphics card: There are independent graphics cards and integrated graphics cards. This is directly related to the response speed of running large program software.
Look at the laptop’s CPU. The CPU determines the running speed of the computer, and its parameters are relatively simple.
When buying a laptop, you mainly look at the performance parameters of the CPU, graphics card, motherboard, memory, hard drive and other hardware. Of course, the most important thing is to consider your intended use and prepared budget, and try to be as targeted as possible within the scope of your budget. The choice should not cause a waste of performance. The performance of hardware devices is a key factor in determining the quality of a computer.
1. The Lenovo G40 series is a 14-inch full-year student notebook launched in April 2014. It has an Intel dual-core processor, the latest series of NVIDIAR5 graphics cards, and adopts Dolby certification. For sound effects, the G40 body is made of metal.

3. g40-70: memory capacity 4GB, memory type DDR3L, number of slots 2 x SO-DIMM. g40-70m: Memory capacity 8GB, memory type DDR3L, number of slots 2 x SO-DIMM.
4. The screen size of Lenovo G40-45 notebook is 14 inches, the display ratio is 16:9, the screen resolution is 1366X768, and it uses a high-definition colorful screen, with excellent overall display effect.
The screen resolution with the highest resolution is 768P, and the high-resolution screen often refers to 1080P. It can display more content, the screen is delicate, and the display effect is good. It is suitable for ordinary consumers. For readers, if the budget is sufficient, it is recommended to start with a high-resolution screen when choosing a notebook screen. It is best to choose a model with 1080P or above to avoid being eliminated after one or two years of use.
The laptop configuration list usually includes processor, memory, storage, graphics card, and screen. Processor The processor is an important part of the computer and affects the overall performance of the computer. The main parameters of the processor include model, number of cores, main frequency, etc.
The screen is the most important output component in a laptop. The higher the resolution of the screen, the clearer the display effect. Common screen sizes include 13 inches, 14 inches, 16 inches, etc. Just choose the corresponding screen size according to your needs. Battery The graphics card is the part of the laptop used to process graphics data.
The above is the detailed content of Laptop maximum configuration parameters. For more information, please follow other related articles on the PHP Chinese website!
