What determines the speed of a computer?

The factors that affect the speed of a computer are:

1. Hardware configuration.

1. CPU working frequency and cache size.

The higher the frequency of the CPU and the larger the cache at all levels, the faster the computer will run. In general, the computer should run smoothly.

The working frequency of the CPU should be higher than 2GHz, so when buying a computer, you should never buy a computer with a very low CPU working frequency.

Operating System Tutorial: Windows).

2. The capacity and working frequency of the memory.

Computers with more than 80% memory usage can make applications slow or unresponsive. If you don't open any programs, the memory usage of your computer is too high, it may be that some background programs are taking up some memory or the memory capacity is too small.

3. The read and write speed of the hard disk.

The read and write speed of a hard drive is an important factor in the performance of your computer. SSDs have much higher read and write speeds than HDDs, so computers with SSDs will run much faster.

Second, the computer system.

1. System performance.

Overly streamlined systems can affect computer performance.

2. The system is automatically updated.

Automatic system updates will increase the system background process, affecting the speed and stability of the system, Microsoft has no longer provided automatic updates to the XP system, win7 and win8 systems can be selected in the "My Computer" attribute in Windows Update to select "never check for updates".

The home version of the win10 system cannot turn off automatic updates, and the professional version requires some complicated settings to turn it off.

3. System vulnerabilities.

Patching system vulnerabilities can increase system background processes, slow down your system, and potentially make your system unstable. Therefore, there is no need to score the computer for physical examination in 360 Security Guard or PC Manager, and there is no need to patch system vulnerabilities.

3. Drivers.

Drivers that are compatible with your computer's hardware and system are the only ones that make your computer fully perform. Some computer discrete graphics card drivers are not installed, and the picture will feel stuck when playing games.

Fourth, heat dissipation problems.

There are some laptops that will automatically reduce their working frequency when the CPU is high to reduce heat generation, and the reduction of the CPU working frequency will seriously affect the running speed of the computer. Generally, you can use the software "Master Lu" to check the computer temperature, and the CPU temperature above 70 degrees Celsius is a high temperature state.

5. Boot startup items and background programs.

1、In the 360 security guard or computer manager computer acceleration item, there is a startup item management,In it, you can disable some software that is not necessary to boot up,For example:iQiyi video、Storm video、Thunder, etc。 But normal drivers in the system cannot be banned.

Frequent optimization of startup items will maintain or improve the speed of your computer's boot and operation.

2. Computer antivirus protection software is sufficient, and it is recommended to use 360 security guard or computer manager. Too much protection software can slow down your system severely.

The speed of the computer is related to the following hardware:

1. The CPU CPU computing rate directly affects the speed of the computer.

2. Memory The impact of memory on system speed is as important as CPU, at present, the XP system requires at least 256MB of memory for smooth operation, and if it can run very smoothly and can run large games, then at least 512MB memory. In addition to memory capacity, memory frequency is also important, generally DDR400 memory.

3. The graphics card mainly affects the speed of 3D games, mainly depending on the display chip, core video memory frequency, video memory bit width, video memory capacity and other indicators.

4. The speed of the hard disk is also very important, at present, the mainstream is 7200 rpm hard disk, and the old 5400 rpm hard disk affects the speed.

5. Whether the combination of each component is reasonable or not, whether it is balanced will also affect the system speed, if there is a system bottleneck, such as P4 with integrated graphics card and 128 memory, then the system bottleneck is very obvious, which will affect the overall performance.

Depending on the computer's CPU, the higher the CPU, the faster the program will run. Memory frequency.

When supported by the motherboard, the higher the memory frequency, the faster the computer will run.

The faster the speed of the processor, the faster it runs and the larger the memory, the larger the other things, and the system can use various programs at the same time.

The higher the CPU, the faster the program will be. Memory frequency, if the motherboard supports it, the higher the memory frequency, the faster the computer will run.

The speed of the computer is generally determined by the CPU, and if the CPU is relatively large and runs relatively fast, then this speed is also very fast.

In terms of hardware** processor, memory, hard disk, graphics card, and software also have an impact, such as the more software that starts at boot, the slower the boot speed.

What determines the speed of the operation of the computer, is it sure that it is a lot of convenience? Just like that memory and the previous network speed is a lot, you can let his words run, and the speed can be accelerated.

The speed of a computer is mainly determined by hardware such as CPU and memory.

CPU, the better the performance of the CPU, the faster the computer will run, and it is also one of the indicators that determine the speed of the computer.

Memory sticks. The better the memory module on the computer and the larger the memory capacity, the more files the computer can cache, which can make the computer run large files with less waiting time.

Graphics card, the graphics card is mainly used in the graphics display, the better the performance of the graphics card, the stronger the ability to process images, which can share some CPU workload and improve the smoothness of the display.

Hard disk, the read and write speed of the hard disk will also affect the speed of opening or depositing files, and now the solid state drive.

performance than HDDs.

Good. computer system.

The more software the platform runs, the more it slows down the overall running speed of the computer, and at the same time, cache junk or files, virus interference, etc., will affect the performance of the computer.

1. CPU: CPU is the brain of the computer and the core of the computing and control of the whole system. CPU-related parameters mainly include frequency, cores, threads, cache size, etc. The larger this parameter, the larger the other parameters, the faster the speed.

2. Memory, generally speaking, the larger the memory, the stronger the ability to process data, and the faster the speed. However, it should be noted that the maximum memory that 32 can support for the system is 4G, that is, even if you configure 6G or even larger memory, the actual available memory will not exceed 4G, and if you use a 64-bit system, you can adapt to larger memory.

3. Hard disk: Hard disk is divided into solid state disk and mechanical hard disk. In terms of speed, solid-state drives are faster than mechanical hard disks, but the cost of solid-state is much higher than that of machinery, so in most cases, you can use the combination of solid-state disks + mechanical disks to configure computers, that is, solid-state disks as system disks, mainly to improve data processing speed, and mechanical hard disks to do other data disks, which may have a certain impact on read and write speeds.

The normal running speed is mainly related to the CPU and memory.

If you are playing a large game, it is also related to the rendering speed of the graphics card, which has a lot to do with the video memory of the graphics card.

If you want to improve the running speed and add memory to change the CPU, due to the number of pins and the number of memory involved in the CPU, sometimes you have to change the matching motherboard, which is a big investment.

Of course, you can also overclock, you don't need to buy CPU and memory, but overclocking will reduce the service life of the hardware, now the book is getting cheaper and cheaper, and it is not a problem to use it for three or four years after overclocking, so it is still cost-effective to overclock, if you add configuration, it is better to use it after overclocking, and it is cost-effective to buy a higher configuration of this book in the future.

This is my personal opinion and I hope it helps.

The CPU is an important factor in determining how fast or slow a computer can be calculated.

Memory is an important factor in determining how fast or slow your computer can run.

The two are interdependent, simply referring to the computing speed depends on the configuration of the CPU, but if the memory configuration is too low, it will affect the overall running speed of the machine, resulting in a decrease in the CPU computing speed. In short, the combination of the two should be reasonable, so that their respective work can run stably and the operating system can be smooth.

Internet speed and hard drive.

Internet speed is on its own. But if the hard disk of the computer is not good, there are too many boot items. In the process of using the computer, some programs will be added from time to time, and the default settings of many programs are boot start, so we must remove the "check" before "boot start" when installing the program.

If we forgot to remove the "check" during installation, or the program did not give us a chance to choose during installation, then we can use "PC Manager" to scan out the boot startup items, and then prohibit the program that we don't want it to boot up at boot. Before using PC Manager to speed up the computer, save the unsaved programs and then close them. Double-click to open "PC Manager", click the "Little Rocket" icon, click "One-click Scan", and you can scan the accelerated items of "Boot Acceleration", "Running Acceleration", "System Acceleration" and "Network Acceleration".

We can click "One-click Acceleration" to speed up all the items that can be accelerated, or we can click "Boot Acceleration" first, and then click "One-click Acceleration" to only speed up the computer.

It is generally determined by the graphics card, CPU and memory of the computer.

CPU, memory, motherboard, hard disk, graphics card, network card network speed (if you need to surf the Internet) will all be affected, if one of them has poor performance, it can cause lag.

Memory, hard disk, CPU, all have to do with it.

The factors that affect the running speed of the computer are not only related to the hardware, but also related to the software, if the computer boots up too many self-starting programs, virus infection, etc., will greatly affect the running speed of the computer.

The hardware, CPU, motherboard, memory, graphics card, hard disk, etc. of the computer fundamentally determine the speed of the computer.

Determine the speed of the computer is the CPU frequency, memory size and graphics card performance, the computer is composed of multiple components, each part affects the speed, in fact, the price determines everything, high performance must be the best level.
