What are the main aspects to evaluate the performance of a computer?

Mainly through two aspects: 1. Hardware aspect: Hardware indicators determine the level of performance, such as computing speed, main frequency, and internal memory capacity; 2. Software aspect: It is the basis for all software operations , the software settings and usage habits determine our direct experience of the performance of the computer.

Hardware:
The hard indicators of the hardware determine the level of performance.
The first is the CPU. The CPU is the core component responsible for the normal operation of the computer. Its performance directly determines the performance indicators of the entire microcomputer.
The second is the motherboard. The motherboard carries the operation of the CPU, memory, graphics card, hard disk, optical drive and other equipment. Its performance must also be considered. The performance indicators of the motherboard are usually reasonably configured based on the CPU performance (including whether the CPU Upgradeable).
Then there is the memory. With good memory performance and large capacity, the normal running speed of the computer will be very fast, and it will not have much impact when running multiple software. When upgrading computers with DDR3 memory in the past to improve performance, the most effective way was to upgrade the memory. Because the computers purchased at that time generally had memory configured according to the needs of the software at that time, the memory was often enough. Now if you use DDR3 memory to run the XP system, it is more than enough. It can be said to be very fast. If you run Windows 7 and 8, it will be enough. will be enough.
The following is the graphics card. The graphics card is responsible for performing some of the display operations. Its performance directly affects the effect and speed of graphics operations. That is what we often mention, how good the display effect is when playing games, whether there will be lags in some complex scenes, whether there will be lags and slowness when running 3D rendering software, etc.
Then there is the hard disk. The performance of the hard disk determines the waiting time when the program is running. If the hard disk performance is not good, the hard disk will be read frequently when running a large program, increasing the program response time.
Other devices such as optical drives have a relatively small direct impact on the performance of microcomputers, so they will not be emphasized here.
Software:
The software settings and usage habits determine our direct experience of the performance of the computer.
The first is system software, which is the basis for the operation of all other software. Without system software, there is no performance.
The current common systems are Windows and IOS, Linux, and Unix. Among them, the software based on Windows system is the most common and has the highest penetration rate. But when it comes to system performance, each has its own merits. Usually we do not need to consider system software. Unless you have special needs, the system is selected based on the hardware configuration at the time. But in theory, the newer the hardware and the older the system, the faster it will run, unless the system can no longer run on the new hardware.
The second is application software, which is our common office software such as word documents, Excel tables, PPT slides, as well as image processing software, multimedia (watching movies, listening to music, etc.) software, etc., I will not list them all. . The capabilities of these software vary based on each company's capabilities. These are not greatly affected by hardware performance, but if the hardware is too old, it will affect the running speed
Then there is game software. This performance is actually more affected by hardware parameters, but it is also affected by system configuration. It is good for system optimization. Yes, the game will be smoother, but if there are many system problems, the game will also be affected.
In general, first choose good hardware, secondly choose a system that suits you, and optimize the system reasonably, and finally choose suitable software and use it rationally. In this way, the performance of the microcomputer can be maximized.
