两根8g内存和一根16g内存差别大吗(单根16g内存好还是两根8g内存好)

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 know a little bit 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 requirement is 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. Generally speaking, it should be The memory is 8G and Android 16G should be storage rather than running memory. The function of running memory is to be responsible for the running of the program. It is a key factor that determines the smoothness of the 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 are of 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.

Is there a difference between two 8 memory modules and one 16g memory module? Two 8-channel memory modules are dual-channel and one 16g memory module is single-channel. The difference is in the following three aspects:

Difference 1. Different concepts

1. Dual-channel memory refers to A memory method that uses two memories of the same brand and the same specification and capacity. Generally speaking, dual-channel means that two memory controllers control two memories respectively. It is theoretically better than single-channel, so it has been widely used.

2. Single-channel memory can only be read or written at the same time. Just like the entrance and exit of a parking lot, only one car can pass in and out at the same time. When the traffic flow is small, it doesn't matter. But when there are more than 100 cars, they will wait for each other.

Difference 2. Different reading speeds

Single-channel memory can only read or write at the same time; dual-channel memory refers to Memory reading and writing use different channels, which can read and write at the same time, doubling the memory bandwidth. Due to the dual-channel memory structure, overclocking is difficult. For users who like DIY, overclocking also has certain limitations.

Difference 3. Different processing capabilities

Dual-channel has advantages over single-channel in terms of reading and writing. In daily opening of software or documents, it is definitely faster than single-channel. . For example, when running some large games, it is a bit difficult due to memory bandwidth issues, and the performance improvement of dual channels can be clearly felt.

To sum up, there are still many differences between two 8G memory sticks and one 16G memory stick! Many people's understanding is very straightforward. If two 8G memory sticks add up, isn't it 16G? If we start from simple mathematical operations, this understanding is not bad. However, if we observe it from multiple aspects such as physical structure, operating efficiency, energy consumption, etc., there is a big difference between the two.

1. Physical structure

The physical structure is the easiest to understand because it is very intuitive. In terms of quantity, there are two 8G ones and one 16G one. Using 8G memory requires two memory slots, while the 16G one only requires one memory slot. Regarding the physical structure, there should be no need to waste any time talking about it.

2. Operational efficiency

This is the core difference between the two. This difference makes the choices made by knowledgeable people and those who do not know completely different. People who are inexperienced will most likely choose a single stick of 16G memory, while people who are knowledgeable will definitely choose two sticks of 8G memory. Although two 8G memories and one 16G memory are the same in capacity, there is a big difference in operating efficiency, and two 8G memories are more secure.

Some professionals have used the same platform to specifically test the operating efficiency of two 8G memories and a single 16G memory. The test results show that the operating efficiency of two 8G memory is 30% higher than that of a single 16G memory. This gap is not generally large, it is very large. You should know what choice you should make.

The main reason why there is such a big difference is that two 8G memories use dual channels, and one 16G memory uses single channels. In electronic products, generally speaking, dual channel (multi-channel) is better than single channel. Let’s make a category. Large parking lots with two (multiple) entrances and exits are better than one entrance and exit, and are less prone to traffic jams. Especially when one of the entrances and exits is faulty, it can better reflect the advantages of multiple entrances and exits. .

3. Energy consumption issues

From the perspective of energy consumption alone, 16G memory has advantages, and the energy consumption of two 8G memory is higher. However, in actual calculation, there is not much difference between the two. Using 16G for a month will not save one kilowatt hour.

4. Conclusion

From the above comparison, I believe everyone will choose two 8G memory. This choice is right. Efficiency is one aspect. More importantly, if one memory is broken, one of the two 8G ones can still be used, but the 16G one cannot be used at all. Even from the perspective of backup, you should choose two 8G ones.

Although two 8G memories have advantages, they cannot be purchased and combined casually. When purchasing memory, you must pay attention to their compatibility, and do not buy randomly from different brands. If you buy it casually, there is a high probability that the memory will be incompatible, resulting in low efficiency. In serious cases, the computer will not be able to be turned on.

Therefore, when purchasing memory, it is best to choose memory from the same manufacturer, the same model, and the same size. This is the best way to maximize the performance of the memory.
