The laptop CPU and memory have the greatest impact on the computer speed. Computer running speed, or computer performance, is determined and affected by the overall hardware. And the overall performance is determined by the worst-performing component. This is the so-called barrel principle.
But games are different. Current 3D games have relatively high requirements for graphics cards. The graphics cards are one level lower, and the performance in the game can be said to be completely different.
For example, RTS games, such as StarCraft 2 and Shogun, test artificial intelligence and CPU. Others, in Battlefield Island, the graphics card and CPU are both important. . In general, the CPU and graphics card are particularly important for games, followed by memory. The issue with the hard drive is the reading speed.
Mainly memory and CPU. CPU is the central processing unit of telecommunications and the brain of the computer. All data must be processed by it, and memory is equal to the channel. The data is preprocessed by the memory. As for the CPU and graphics card, as long as the screen displayed by your computer is not very complicated, the requirements for the graphics card are not very high.
Graphics card (GPU): Responsible for outputting image and video signals, and supporting 3D image processing and games. Power supply: The source of energy that powers various components to operate. Radiator: Keeps the computer cool and avoids various problems caused by overheating. Monitor: An output device that outputs computer images.
CPU: Central processing unit is a very large-scale integrated circuit with many pins. It is the core of the computer. It is the core of computer calculation and control. It processes various information calculations, just like human beings. Calculating math problems requires the same mental calculations.
The function of memory is to temporarily store some files and applications that need to be viewed or operated. The data in the memory will be lost due to power outage. The CPU needs to read data from the hard disk, and the cache of the CPU and the speed of the hard disk The difference is too big, the memory acts as a buffer, the hard disk data is placed in the memory, and the CPU reads it from the memory.
Memory generally refers to random access memory, referred to as RAM. As mentioned earlier, static memory (SRAM) is used as the system's cache, and the computer memory we usually refer to refers to dynamic memory, that is, DRAM.
The main function of the graphics card is to perform corresponding processing according to the instructions and relevant data provided by the CPU when the program is running, and then convert it into a signal that the monitor can accept, and then send it to the screen for display. .
The host looks like a whole from the outside, but when you open the case, you will know that the inside of the case is composed of a variety of independent components. The various components of the computer host include the motherboard, CPU, hard disk, memory, optical drive, graphics card, sound card, power supply and other equipment. A host is a collection of devices.
: CPU: It is a collection of calculations and instructions, with processing Instructions, execution of operations, control of time, processing of data, etc. 4: Memory: Responsible for data exchange between the data on the hard disk or motherboard and the processor. 5: Hard disk: stores and reads data processed by the computer.
The main function of the graphics card is to perform corresponding processing according to the instructions and relevant data provided by the CPU when the program is running, and then convert it into a signal that the monitor can accept, and then send it to the screen for display. .
The function of the graphics card is to process images, and then transmit the processed images to the monitor for display. The CPU is the heart of the computer, and its performance determines the speed at which the computer processes data. The hard disk is the memory center of the computer. The larger the hard disk, the more things can be stored and the faster the speed, the faster the file processing speed.
The display card (also known as the display adapter) is used to control the display mode of the monitor. There are also control circuits in the monitor, but the main function is the display card. In terms of bus type, there are four types of graphics cards: ISA, VESA, PCI, and AGP.
1. To add memory, you can buy 1G memory of the same frequency to form a dual channel with the original memory, or you can buy two 248g ddr3 memory. to upgrade. Considering that the configuration of your computer is relatively outdated, it is recommended not to buy an 8g strip to avoid excessive performance.
2. X4641 has about the same performance as I32120 and can handle LOL. Moreover, the platform has no upgrade space and cannot improve computing performance by replacing the CPU alone.
3. Because all of them have been eliminated, even if the upgrade speed will not be obvious, it is recommended to replace the motherboard, CPU, graphics card, memory, hard drive, power supply, and the others can be retained. If the family uses AM3 dual-core, all these hardware should be from first-line brands, which cost about 1,000 yuan. Five to two thousand, if you replace it with a quad-core, it will be about two thousand to two thousand five.
4. The upgrade method if the computer configuration is too low is: replace the hard disk, increase the memory, and replace the graphics card. Replacing the Hard Drive The hard drive is where your computer stores data. If your computer's configuration is too low, your hard drive may be a low-speed, low-capacity mechanical hard drive.
