苹果16g内存和8g内存的差别(12g内存和16g内存区别)

However, the running speed may not be greatly improved, but there are still subtle differences. The reasons for the difference are related to the CPU, motherboard, hard disk, graphics card and other components. When people use it, the difference between 8g and 16g of notebook memory is different. In theory, the larger the memory, the smoother the operation, but it also depends on our actual situation; we must consider the maximum amount of memory supported by the motherboard. If it is 8G, then both There is no difference, 16G consumes more power. If it is 16G, 16G is better, faster and more powerful; 1. The actual available space of 16g ​​memory in different computers is less than 16g, and 8g memory is less than 8G, so 16g memory in computers has more performance improvement. 2. The performance is different in different installations. Two 8G memory sticks can generally improve performance by about 30% compared to installing one 16G memory stick, so some people who have a little knowledge are buying and assembling memory sticks.
There is no difference between the normal use of 8G memory and 16G memory, because the 8G memory of the computer can no longer be used up. However, for some large-scale 3D games and large-scale software, in the case of 2K or 4K high resolution, 16G memory is better than 8G memory is more advantageous, but you may not be using large-scale 3D games and large-scale software more than 90% of the time; the difference is as follows: 1MaxTechXcode is a test that simulates compiled code, in which 16GB has a score of 122 points, and 8GB has a score of 136 points. The lower the better2 In the test, the biggest difference between 8GB and 16GB is exporting from an 8KRAWR3D to 4K, 8GB MacBook;2 For game enthusiasts, the current maximum memory requirement for games is 6GB, so 8GB is enough for game lovers At present, there is no difference between 8G and 16G, but in the future there may be games with higher requirements, and there will be a difference. 3 For video and animation producers, 8G is very low, and 16 is just barely; the answer is yes The main function of computer memory is to provide running space for users when using computers to run systems and software. The larger the running space, the more software they can run, and the faster the running speed. Assuming that 8G memory can run 5 software at the same time, the running speed is is 5 seconds, then 16G memory can run 10 at the same time; 116G memory is better than 8G memory, because the larger the memory, the better the performance of the computer. 2 If there are many software that are frequently run or software with a particularly large memory usage is opened, use 16G memory Apple computers run better. A simple way to check the computer configuration: 1CPU mainly depends on the number of cores and frequency, the higher the above two parameters; there is not much difference between 8g and 16g of computer memory for daily use. Under the needs of office, entertainment and games, 16GB is not There will be a very obvious gap. But if you are engaged in professional use such as video and audio, 16GB of storage can bring faster processing speed. The following is a detailed introduction 1. If it is a general home or office.
The difference between notebook 8g and 16g memory is the size of the memory. The current 8GB memory of notebook products can meet most daily needs, whether it is daily text processing, simple entertainment such as watching videos, or large-scale 3D For games, 8G can provide good operation, but for video and animation producers, 8G; Hello, there is not much difference between 8g and 16g of computer memory in daily use, but there is a big difference in professional fields such as office games, such as For video, audio, etc., if it is for general home or office use, 8GB of running memory is basically sufficient, so the difference between 16GB and 16GB is not big. For most daily-use software and games, 8GB of memory is required.
Because today's large-scale 3D games are still compatible with old devices, the memory requirements are almost 8G, which is considered very good. Finally, the big difference is that if you are a film, television or animation producer, you will be rendering your work. When I discovered the hourly difference in memory gap, of course the main lag here is not the memory but the graphics card; the difference in size between 18G and 16G memory is related to the purpose of the computer. If the user uses the computer to edit documents, chat and watch movies, 8G memory is enough Even if it is equipped with 16G memory, its performance cannot be fully exerted. In terms of user experience, there is almost no difference between the two. 2 But if the user uses the computer to play with pictures; first of all, the storage of Apple computers cannot be 8G. In general, it should be The memory is 8G and Android 16G should be storage rather than running memory. The function of running memory is responsible for the running of the program. It is a key factor that determines the smoothness of the mobile phone. The function of storage memory is to store the data of the program. Simply put, it stores the memory. Equivalent to a warehouse.
1 The price is different. The price of 16g ​​memory is higher than the price of 8gn memory. 2 The capacity is different. 16GB and 8GB memory have the same brand and chip specifications. There is only a difference in capacity, that is, the capacity of 16GB memory is 8GB memory. Twice the capacity 3. The amount of data that can be processed at a time is different. The larger the memory capacity, table; 1. Different sizes. The actual available space of 16g ​​memory of computer is less than 16g, and 8g memory is less than 8G. Therefore, 16g memory of computer has more performance improvement. 2. Different performance Installing two 8G memory sticks can generally improve performance by about 30% compared to installing one 16G memory stick, so some people who know a little bit are buying and assembling memory sticks.

1. 16G memory is better than 8G memory, because the larger the memory, the better the performance of the computer.
2. If you frequently run a lot of software or open software that takes up a lot of memory, an Apple computer with 16g of memory will run better.
[Easy way to check computer configuration]
1. CPU: mainly depends on the number of cores and main frequency. The higher the above two parameters, the better the performance;
2. Memory: depends on the memory size , the larger the memory, the better the performance;
3. Motherboard: You don’t need to look at the parameters, it mainly depends on the interface. The interface can meet your needs;
4. Hard drive: whether it is a mechanical hard drive or a solid-state hard drive. The mechanical hard disk depends on the number of revolutions. The greater the number of revolutions, the better the performance;
5. Power supply: Just meet the needs of your own computer.
[Selection of computer memory usage]
1. Ordinary home users: 4GB of memory is basically enough, 8G is enough, and there is almost no change when adding 16G. Because most applications are written in a 32-bit environment, the memory usage will not exceed 4G.
2. Game enthusiasts: Currently, the maximum memory requirement for games is 6GB. Therefore, 8GB is enough for game lovers. At present, there is no difference between 8G and 16G, but in the future there may be more demanding games, and there will be a difference.
3. Video and animation producers: 8G is very low, and 16G is just barely. It is recommended that 32G or above is appropriate. In addition, be sure to set up dual channels.

Demo model: Iphone13&&Huawei P50&&Xiaomi 11 System version: iOS15&&HarmonyOS2&&MIUI12.51. Different memory capacity: under the same conditions, 16G memory capacity is 8G memory capacity double.
2. Processing efficiency is different: the larger the memory capacity, the larger the amount of data that the memory can process at a time, and the processing efficiency is higher, that is, the processing efficiency of 16G is greater than that of 8G.
3. Different preloading rates: Under the same conditions, the more things are preloaded, the faster the memory will be, and the smaller the memory will be, the more likely it will be stuck. Then the 16G preloading rate is greater than 8G.
Machine access memory:
Also called main memory, it is an internal memory that directly exchanges data with the CPU. It can be read and written at any time (except when refreshing), is very fast, and is often used as a temporary data storage medium for the operating system or other running programs. When RAM is working, information can be written (stored) or read (retrieved) from any specified address at any time. The biggest difference between it and ROM is the volatility of data, that is, the stored data will be lost once the power is turned off. RAM is used in computers and digital systems to temporarily store programs, data, and intermediate results.

The main differences between 8g and 16g computer memory are different sizes, different performances, different functions, etc.

1. Different sizes

The actual available space of computer 16g memory is less than 16g, and 8g memory is less than 8g, so computer 16g memory has more performance improvement.

2. Different performance

Installing two 8g memory sticks can generally improve performance by about 30% compared to installing one 16g memory stick, so some People who know a little bit will choose to buy two 8g ones when buying and assembling memory sticks.

Of course, dual-pass memory modules cannot be blindly selected. They should meet the following conditions at the same time: the two memory modules are the same in terms of timing, voltage, capacity, and DRAM chips, and the optimal frequency range requires Be as consistent as possible, which means that the two memory sticks should be roughly similar in terms of parameters and performance.

3. Different functions

The newly purchased game notebooks and desktop computers, with the support of 7th generation i5, 8th generation i3 and SSD, have 8g The memory can cope with daily use without any problem. Of course, except for special purposes, for PS photo retouching, video editing and other work, 32g is basically the best choice.

General gamers who use 1050Ti (4GB video memory) or 1060 (6g video memory) level graphics cards do not need to consider adding memory for the time being, but if the integrated graphics, MX150 or independent graphics memory is less than 3g, they want to run Some stand-alone games require 16g of memory.

Computer memory module selection method:

When using the same specifications of memory, it is still recommended to choose two 8g memory as much as possible, because this can form a double Channel memory thereby increases memory bandwidth. In the case of memories with the same frequency, if the bandwidth of dual-channel memory is directly doubled, the performance of the memory and even the entire system can be effectively improved. However, this cannot be achieved if there is only a single 16g memory. The memory bandwidth is only Is half of dual channel.

The most important thing for memory is still capacity. As long as the capacity is sufficient, the performance improvement brought by frequency and bandwidth is still relatively limited, so whether it is two 8g memory or a single 16g The memory capacity is the same and there is no difference at all. The only difference between the two is the bandwidth.

Two 8g memories form a dual-channel bandwidth that doubles. This can be directly reflected in the memory test software. The running score performance will be much better than that of a single-channel 16g memory, but now the frequency of ddr4 memory is already very high. , the benefits of doubling bandwidth in actual use are not as obvious as running scores. Some performance improvements will only be reflected in some games and software that are more sensitive to CPU single-core performance, commonly known as poorly optimized software.

If you look at it from the other hand, the memory slots of computer motherboards are limited. Desktops generally have at least 4 slots, but laptops generally only have two slots at most. Computers have a large demand for memory. Plugging in two 8G memory will occupy all the memory slots, completely losing room for future upgrades. However, if you only plug in one 16G memory, the remaining memory slots can still be used as backup. This is equivalent to saving the cost of future upgrades.
