In fact, the answer to this question depends first on the bottleneck of my own computer. For example, I recently upgraded my friend's computer. His original configuration was Celeron G530+4GB memory+1TB hard disk. Seriously, I really want him to change the whole set. However, due to limited funds, I can only upgrade one thing, let him upgrade SSD first, and the others will wait.
As long as it is not an ancient computer (for example, it still uses DDR2 memory), if the computer still uses HDD, adding an SSD as a system disk will definitely improve the most. The power of SSD is that the random reading delay is only a few tenths of a millisecond, while the random reading delay of 7200RPM is about 7 milliseconds, and the hard disk of 5400RPM is as high as 9 milliseconds. Delay response is the random reading ability in performance, and the random reading ability of SSD is far from that of HDD, which lies in the switch.
The above picture shows the time required to save a 4GB PSD file in Photoshop, which better shows how much SSD is better than HDD, and basically kills it completely.
Of course, if the current computer is already using SSD, you can also consider changing to a faster one. For example, upgrading SATA SSD to the latest M.2 SSD with PCI-E 3.0 x4 will be faster, but only if other accessories are bottlenecks. In today's era, 4GB of memory is not enough, and the memory should be upgraded to at least 8GB. Of course, it is better to go directly to 16GB. However, at the current memory price,
Upgrading CPU is actually the most troublesome upgrade of the three things. First, you have to determine what kind of CPU your motherboard supports. You can see which pin the original CPU is, and then buy a CPU with the same pin. If you are using a dual-core Core i3 Pentium or Celeron, it is recommended to upgrade to a quad-core Core i5 or Core i7. LGA1155/150 platform. Friends who use a unique platform can consider Xeon E3 series. If you are using quad-core friends now, don't consider upgrading CPU. Upgrading Core i5 to Core i7 will not bring much improvement. When they can't take it anymore.
Triangular judgment
Computers before 1 and 16 have priority to upgrade their memory.
Judgment: This kind of computer generally runs win7, which is friendly to mechanical hard disk, so upgrading memory is the first choice.
2. Computers after16 will be upgraded to solid state first.
Judgment: This kind of computer generally runs win 10. Win 10 computer won't be cheated if you buy it back. It must have started with 8g memory. If I hadn't mentioned it, Win 10 was seriously fragmented when it was running, which would make Win 10 system unfriendly to the mechanical hard disk, so upgrading the solid state is fundamental.
3, Core 2 7 generation upgrade is of little significance, others you consider yourself.
Core 2 7 always uses 2-4, 4-4, 4-8, and frequently changes platforms. Now 10 generation i3- 10 100CPU is equivalent to Core 2 7 generation i7, so it is not recommended to keep the status quo unless you build a car behind closed doors, and you can find a current i7 processor in the seafood market.
Summary: The upgrade method varies from machine to machine, and cannot be generalized.
Before answering this question, we must first have a simple understanding of the above accessories, otherwise you can't judge which one is the most obvious. You should know that a computer is divided into CPU, graphics card, motherboard, memory, hard disk, power supply, chassis and peripherals. Theoretically, the bottleneck of any accessory will affect the speed of the computer. To be precise, the most obvious thing to speed up is the bottleneck on that component. Simply speaking, the speed of a component is the fastest, which doesn't seem too strict. It is estimated that the absence of any organ will affect the overall coordination of this person, and so will computers.
Next, I will talk about the specific uses of CPU, memory and SSD respectively. What role does he play in the computer? Let's talk about CPU first. This CPU refers to the central processing unit of the computer. Why is it called CPU? In fact, it is the abbreviation of his English name in the industry. His full name is CPU. His main purpose is to control the overall operation of the computer. In other words, he is the brain of the computer, and all the running commands are issued from him, which means that his speed directly determines the running speed of the whole computer, so the quality and performance of a computer are basically determined by the performance of the CPU. We can also think that CPU is the key to the computer. The reason why CPU is so expensive is that it belongs to the core component of a computer, and its performance determines the grade of this computer.
Let's talk about memory again. This memory is a place to provide temporary running space for software running. It is characterized by faster speed than hard disk, between CPU and hard disk. In other words, when the CPU wants to execute an instruction to run an application, it will cache the required data in the hard disk for later use. When you need these data, you can read them directly from the newer and faster memory, and you will never retrieve the data from the hard disk again. The purpose of this is to improve the speed of software running, that is to say, the size of memory is directly related to the speed of software and system running. You may often hear a saying that playing a game card means that there is not enough memory. Although this is not rigorous, in a sense, too small memory will indeed lead to the phenomenon of slow card running in large games. Let me give you a simple example. This memory is like a product processing platform. If you need to produce a product, it must be done on the processing platform. If your processing table is too small, you can't finish a bigger product at once. If the volume of the product you produce is larger than the processing table can bear, it will only lead to abnormal production or mass production for many times, which will naturally slow down the whole production progress, so it is also a fact that memory affects the running speed of the computer.
Finally, SSD is a kind of hard disk. The main purpose of so-called hard disk is to store data. The biggest difference between SSD and memory is that it is larger than memory, and data will not disappear after power failure, while memory only provides temporary cache space. The data will disappear after power failure. SSD is a solid-state hard disk, and its reading speed is definitely higher than that of traditional mechanical hard disk, but at the same time, its price is also higher than that of traditional solid-state hard disk. The typical characteristics of SSD are fast reading speed, low capacity and relatively expensive price. In fact, in plain language, a hard disk is equivalent to a computer warehouse. All application data and system installation data are stored in this big warehouse. When necessary, we can take them out of this warehouse and run them in memory. In other words, the size of the hard disk determines the number of installed applications and the size of stored data, just like our usual photos and videos. It's all in the hard disk, so the hard disk is also a very important component, but it's not as good as CPU and memory. To be sure, the hard disk only affects the reading and writing speed, and the impact on the overall performance is not too obvious.
Everyone should have known their role from above, and now they should know that upgrading is the most obvious. In terms of overall performance, upgrading CPU is definitely the first, followed by the largest memory, and finally the hard disk. However, one thing here depends on where the ultimate bottleneck of the computer is. If there is a bottleneck in the CPU, upgrade the CPU first. If there is a memory bottleneck, upgrade the memory in the game. If the performance of the hard disk is insufficient, upgrade the hard disk first. Therefore, the specific upgrade is decided according to the hardware configuration of the computer itself. It is not correct to upgrade the accessories blindly. It's like a friend of mine heard gunshots from somewhere in order to play a big game, saying that the game card was too bad, so it would be good to change it to a high-end graphics card. As a result, he replaced his old Pentium with a high-end flagship graphics card, and the game performance did not improve. The reason for finding a circle is that the CPU can't meet the needs of the game and the performance of the graphics card can't be exerted. Therefore, for computers, there must be a balance between accessories and accessories, and there can be no bottleneck unilaterally. Otherwise, it's useless for you to upgrade. Well, I personally said so much. I wonder what my friends think?
CPU, memory and SSD can all improve the speed of the computer, but the effect of upgrading SSD is obvious under the same conditions. After all, upgrading CPU and memory depends on the support of the motherboard. It is better to upgrade SSD quickly. SSD can sometimes save an old notebook.
Because I have been engaged in the electronic communication industry for a long time, occupational diseases come when I see such problems.
First, the notebook angle.
Since the cpu and motherboard of most notebooks are packaged together, upgrading the cpu and motherboard is too expensive and unnecessary. Therefore, notebooks must give priority to upgrading SSD. Note that this situation mostly happened in the past, and almost all the existing or purchased notebooks in the last three years have solid-state hard disks, which can't be killed with a stick.
Most notebook combinations purchased before 12 are as follows:
4G single channel +500G mechanical keyboard
Most notebook combinations purchased after 15 are as follows:
4G dual channel+single disk position of mechanical hard disk
After 18, the combination of most notebooks is as follows:
8G Dual Channel +SSD+ Dual Disk Position
So choose the upgrade configuration according to the notebook you bought.
Second, the desktop computer angle
The advantage of desktop computers is that they are easy to replace.
If your cpu is a 20 yuan cpu like g 16 10, even if you upgrade the solid state, the effect will not be ideal. In this case, change the i5-3 processor, and the performance will go up directly.
If the cpu is a mid-range Core series processor, changing the speed of solid-state hard disk is the most favorable.
Third, memory upgrade.
Having said so much, my memory has never been mentioned. The fundamental reason is that memory plays a less important role in speeding up than cpu and hard disk.
If your computer's cpu is average, and the mechanical hard disk and memory are 4G, the core functions of the notebook are office and desk. Then it is best to replace 8G memory in case of insufficient budget. In particular, software such as wps consumes a lot of memory.
When my client reported more information about the form, the form reached more than 500 lines, and many information could not be read. That computer processor is A8. My first idea was to add a solid state drive, but it turned out to be useless. Add 4G memory and it will be ready soon.
Ordinary people may not use so much tabular data, so this phenomenon has been ignored.
Look at the bottleneck first, and then you can know which solution is the most effective! According to my practice, if you don't play games, most old computers, especially the original ones, have high cpu (which can sell at a high price), stingy memory (which always lags behind the demand of windows and the latest application software at that time) and poor hard disk (which often uses the model with the highest capacity in the older generation series, that is to say, the performance is poor and the capacity looks quite large). These machines were not properly configured from the factory, and the problems became more obvious after many years. In actual use, the bottleneck is often hard disk, because of the lack of memory, exchanging files consumes a lot of disk performance, which is a serious drag. The detection method is simple: open the task manager, and you can see that the cpu usage is not high, the memory usage is high, and the disk usage is full for a long time. Then look at the hard disk light that flashes or even doesn't light for a long time on the chassis.
This is my most common situation, so the most effective solution is to replace or install ssd as the system disk and put all the exchange files on it at the same time. Even if you are an old machine in 2008, you can switch to win 10 after switching to ssd, which is faster than the original mechanical hard disk +winxp! Memory usage is also less (because win 10 has its own memory compression technology, but the load on the disk is higher).
Therefore, for an old machine that doesn't play games and wants to prolong its life, the most valuable and effective solution is to go to ssd without hesitation, and then add memory according to the situation and budget.
If the cpu is not enough, it is usually necessary to replace the memory of three cpu motherboards together. Maybe the power supply is not enough, and the chassis has to be changed. This whole method is not called upgrading, but changing the computer budget. So the most cost-effective thing is to change ssd! Direct result.
If there is enough memory, you can also consider increasing the primo cache to improve the performance of all mechanical hard disks with ssd. The principle is similar to intel's Otten, but the performance is a little worse, but all computers and all models can adapt, and it is immediate!
By the way, if you buy a new computer, according to last year's market, 8gb memory and 256 GB ssd are the bottom line, otherwise you will spend thousands of dollars to buy a new computer with an i7 mechanical hard disk. If you are used to SSD, it is really difficult to use! I can't find the refreshing response of ssd at all. Once you use ssd, you can never go back. A computer without ssd is not a computer. ...
What I said above is actually the improvement of operational response speed, which directly affects the experience. If the cpu is fully loaded, it still needs time to complete the operation after this action. In that case, the cpu will be changed, usually the memory of the cpu motherboard will also be changed together. It can be said that this computer is hopeless.
If the graphics card is more important to play games, you have to change the graphics card, and you have to consider the pcie version. You may have to change the motherboard, which means you may have to change the cpu motherboard memory together.
So, first of all, we must figure out where the bottleneck is. The simplest judgment method is to open the task manager at any time for long-term observation, which is simple and effective. If the latest version of win 10 has gpu load monitoring, the computer's judgment will go further and no third-party tools are needed. But if the old computer may not work at all, win10 ... ...
Children's shoes, your question is more difficult. Usually, you cut a configuration diagram, and then we will give suggestions according to your configuration. The general rule is the short board effect of barrel, which configuration upgrade is the worst. The general upgrade order is: memory SSD graphics card CPU(CPU is rarely replaced, because it can only be replaced by the same generation of U, and the effect of changing U is generally not obvious, depending on the configuration), and you should also consider the power acceptance ability when changing the graphics card. Each configuration is different, the motherboard environment is different, and the upgraded things are different! It is your problem!
The most obvious speed increase should be SSD solid state drive. The speed-up of the CPU of the graphics card is only the running speed of the content loaded into the memory. Now you may not feel anything about DDR3 and DDR4 in memory, because the current CPU is running multiple tasks on Core i7 and all of them are running operations, which makes you feel that DDR3 and DDR4 are different. Why do you feel this way? At present, the data throughput of software or large-scale games and CPU exchange DDR3 1333hz can completely cope with it, even more than enough, not to mention dual-channel DDR3. According to the current large-scale game Call of Duty 14, it occupies 6.8G of memory, and the data throughput bandwidth of CPU and memory is only about 1.2G per second. 1333DDR3 bandwidth 1 1.6G, which is completely sufficient. Want to see the difference, just install 32G memory DDR3 and DDR4, and play five large games to see the difference, provided that the CPU and graphics card are good.
It can be said that SSD speed is the most obvious! Take my old slag notebook as an example, the configuration is as follows: CPUi3-32 17u, memory 4GB, hard disk 500G, 5400rpm.
Under the original configuration, it takes more than 2 minutes to turn on the computer, beating more than 10% computers on the market. After turning on the computer, the icon reacts for a few seconds before it is displayed. It takes one minute for Caton to run normally! In the process of saving this computer, I also broke my heart. After various installation systems failed, I first bought a piece of Kingston's 4G memory, which did not improve after installation, and the memory ratio was not so high. I added a 120gSSD at the back, changed the optical drive into a hard disk slot, put the mechanical hard disk in the position of the optical drive, and set the SSD as a system disk. After installing the system, I started 17 seconds!
From the original boot time of more than 2 minutes to the flying of 17 seconds, 6, the software icon display does not need to be refreshed for a few seconds, and it can run normally after booting, and it will not be stuck for a long time. I feel that my scum computer can fight for another two years! In addition to boot upgrade, the startup speed of software installed on SSD has also been significantly improved. Actually, I don't need to play anything on the computer. Usually I hang a Q in the background and open a PS with video editing software, and there is no obvious jam. I used to feel stuck when I opened a PS.
It can be said that this SSD saved my computer and at least improved my computer performance by 30%! (This unprofessional evaluation only makes me feel that my computer has improved, and it doesn't mean how much performance SSD can improve! ) I always think that CPU is too rubbish! It's really rubbish. It's enough to change SSD. So I think changing a solid state drive will improve the most!
Different parts of a computer have different functions:
CPU: It is responsible for the running and execution of all instructions, and the running speed of the computer is determined by it.
Graphics card: It is responsible for converting the signals recognized by the output monitor and rendering 3D graphics. The finer the screen, the more powerful the graphics card.
Hard disk: responsible for storing all data (system, application software, game software, audio-visual files, etc. ). The greater the capacity, the more things you can hold, and its speed determines the reading and writing speed of all data.
Memory: responsible for caching data to be read by CPU. Hard disk stores the data to be used in memory in advance, which is convenient for CPU to call quickly and smoothly. The larger its capacity, the more data it can cache and the longer the CPU runs smoothly.
What are the benefits of SSD?
Motherboard: responsible for communication and transmission between components. Its bus bandwidth determines the communication efficiency between components and what level of components can be supported. From your point of view, due to the use of solid-state hard disk with fast reading and writing speed, the loading speed of data before being sent to CPU for execution will be greatly improved, which is reflected in the system startup speed, file opening speed, copy and paste speed, game loading speed and so on. When reading data, the speed of subsequent operations is determined by CPU and graphics card. So the speed of the hard disk can determine the operating experience, but it can't determine the operation speed. The comprehensive ability of a computer is still determined by comprehensive components.
