Notebook CPUs are mainly Intel and AMD series. Intel mainly has Celeron, Pentium, Core i3, i5, i7 and Atom series. I5 is currently the most cost-effective; AMD mainly has A4, A6, A8, A10 and E series. Among them, the A8 series is more optional.
The main frequency is also called the clock frequency, and the unit is MHz, which is used to indicate the CPU's operation speed. The CPU main frequency includes two parts: the external frequency and the multiplier. The product of the two is the main frequency. Usually higher frequency notebooks can improve certain performance, but it is only one aspect, not higher is better.
The type and frequency of memory have some impact on performance, but in contrast, the impact of capacity is greater. General notebooks range from 2GB to 8GB, special games will be 16GB to 32GB, it is recommended that generally 4GB can meet daily requirements.
Different types of memory transmission types are different, and are different in terms of transmission rate, operating frequency, working method, and working voltage. Most notebooks still use DDR3, 1333MHz and 1600MHz; or DDR3L low voltage version, energy consumption and heat will be lower.
Abbreviated as SSD, due to its fast read and write, light weight, low energy consumption and small size, it is gradually replacing traditional mechanical hard drives, but high price and life limit are also one of the purchase defects. Most notebooks use SSD as the system disk. The concept of a mechanical hard disk as a storage disk.
Refers to the size of the diagonal of the notebook screen, usually expressed in inches. Generally, 15-inch and 17-inch screen sizes are used. The 15-inch screen is a relatively acceptable size and weight.
The ratio of the screen width to the height is called the screen ratio. At present, the standard screen ratios are generally 4: 3 and 16: 9. The wide screen generally refers to the 16: 9 screen ratio.
It refers to the multiplying ratio of how many pixels are divided in the horizontal and vertical directions of the screen. Due to different screen ratios and different graphics card outputs, the resolutions are all different. Common are 1920 * 1080, 1366 * 768, etc. Popularity such as 3840 * 2160 and so on.
Graphics card type
Graphics cards used in notebooks are divided into integrated display, nuclear display and independent display. The integrated display and nuclear display are mainly integrated on the motherboard or CPU to share the system memory type of graphics card; the independent display also said that the GPU has independent display memory. Graphics cards are NVIDIA series and AMD series, of which GTX series of N cards are more common.
The core chip of the graphics card, its performance directly determines the performance of the graphics card. The status of the display chip in the graphics card is equivalent to the status of the CPU in the computer and is the core of the entire graphics card. At present, only NVIDIA and ATI companies are manufacturers that design and manufacture display chips.
The video card itself has a memory for storing graphics and image data. The size of the video memory determines the size of the display resolution and the number of colors that can be displayed on the display. Generally speaking, the larger the video memory, the higher its performance.
