In 2024, most mainstream game books will adopt the same configuration: a single 16GB memory. Compared with the previous 2 × 8GB memory combination, the single 16GB memory capacity remains unchanged, but it has changed from a dual socket to a single socket. The benefits are obvious: the capacity is still 16GB, which means that the notebook is sufficient for regular applications, such as daily light office work, class study, playing with 3A masterpieces/online games, watching videos and so on; At the same time, it is also easy to upgrade. In the 2 × 8GB era, if users want to upgrade 32GB of memory, they have to dispose of two 8GB of memory and buy two 16GB of memory. Now, you only need to buy one 16GB of memory, which costs half of the cost and saves a lot of things.
However, some kids worry that if they don't upgrade the memory after buying the game book, will the single 16GB memory that is standard in the factory of the notebook affect the overall performance of the notebook? Especially for games and applications that partially eat memory performance. This problem does exist objectively, so we also found a popular game book in the market at present, and compared the 1 × 16GB memory of this machine with the application performance of the measured 2 × 16GB memory to see the answer.
The measured model is ASUS Tianxuan 5 Pro, with the specific configuration of i9 14900HX+RTX 4060 core hardware combination. It is matched with a 16 inch 2560 × 1600 resolution 165Hz high brightness screen. The commercially available version carries 16GB DDR5 5600MHz memory, which is a typical game book with a top processor+dessert level display this year. In addition, the machine has reserved M.2 The hard disk bit is convenient for users to upgrade SSDs. In the following measurement, Niu Shu tested the actual application performance of the machine in 1 × 16GB memory and 2 × 16GB memory respectively.
Processor benchmark and light application performance test
Those who are familiar with computers know that the memory channel does not affect the performance release of the processor. However, we still ran the benchmark test of Cinebench R23 processor, mainly to explain this to those who do not know much about computers. As shown below, the R23 multi-core score is more than 27000 points, whether it is 1 × 16GB memory on the left or 2 × 16GB memory on the right. There is a slight difference in the value, which is a normal test error
Is there any difference in the daily office, web browsing, video playing and other light applications? PCMark10 is a test project for mild office applications, covering common basic functions (program startup, video conference, web browsing), productivity (tables and documents), digital content creation (photo editing, rendering, and video editing), etc. In 1 × 16GB memory, the total score of Tianxuan 5 Pro is 8466, and the three subprojects are 11097/11152/13304 respectively; In 2 × 16GB memory, the total score of Tianxuan 5 Pro is 8470, and the three subprojects are 10802/11464/13316 respectively; It can almost be said that there is no difference. A little difference in test scores is also a normal error.
Here is a brief summary: When the memory capacity is sufficient, 1 × 16GB is basically the same as 2 × 16GB for processor performance release and daily use.
Picture processing and video transcoding test
At present, visual applications are also commonly used. Uncle Niu examined how Tianxuan 5 Pro handles plane photos and video transcoding under different memory capacities.
The first is Ps and LrC photo processing. UL Procyon's photo benchmark test is used as an examination item. This test will call Ps and LrC to perform a series of post editing of photos, including import and export operations. In 1 × 16GB memory, the total score of Tianxuan 5 Pro is 7993, and in 2 × 16GB memory, the total score of Tianxuan 5 Pro is 8639. In these two applications, there is still some gap, but it is not big. 2 × 16GB is about 8% ahead. In addition, as a reference, the 8 core 16 thread H processor+32GB of memory scored around 6300 in this test.
The second is video transcoding test, which is relatively time-consuming in video production and basically depends on the computer's own hardware processing. The test project is to use Media Encoder CC to transcode a segment of more than 18 minutes (for personal level video production, this is a long project) of 4K video to 1080P 24fps video, using RTX 4060 CUDA acceleration. With 1 × 16GB of memory, the memory occupation rate of Tianxuan 5 Pro is about 12.4GB, which takes 2 minutes and 39 seconds; With 2 × 16GB of memory, the memory occupation rate of Tianxuan 5 Pro is about 19GB, which takes 2 minutes and 36 seconds. Although the memory usage of the latter is significantly higher, the efficiency of video transcoding has only increased by 3 seconds. It should be said that this difference can be ignored to some extent, especially when your video time is relatively short, such as within 10 minutes.
Processor full load rendering test
Next, let's take a look at the full load rendering test of the processor. The test project is the classic Blender Classroom. With 1 × 16GB of memory, it takes 3 minutes and 56 seconds to select 5 Pro; With 2 × 16GB memory, it takes 3 minutes and 51 seconds to select 5 Pro; There are differences, but they are still not obvious.
Game performance measurement
As for whether a single 16GB of memory has an impact on the notebook, the performance of the game may be the most concerned point. What about the actual situation? The Tianxuan 5 Pro is matched with a 16 inch 2560 × 1600 resolution 165Hz high brightness screen, so in the following game measurement, we set the game to 2.5K resolution preset the highest picture quality, and some games have turned on DLSS 3 quality.
From the overall measured situation of the 3A game of Tianxuan 5 Pro, 1 × 16GB has no difference from 2 × 16GB, and even the average frame rate results of benchmark tests of some games are exactly the same, such as Extreme Racing: Horizon 5, Isolated Island 6, Watchdog: The Army, etc. Other games have different levels, but that is the difference of one frame. As a test error, generally speaking, there is no difference in the average frame rate of the game test between 2 × 16GB and 1 × 16GB. Here, you can relax. It is also very appropriate to play games for game books with 16GB of memory, such as Tianxuan 5 Pro.
The average frame rate of Horror 6 is the same
Tomb Raider: Shadow, one frame higher in 32GB memory
So, what applications are the gaps between 1 × 16GB and 2 × 16GB? It is mainly about the application of memory bandwidth. The memory bandwidth of 2 × 16GB is higher. For example, in the memory bandwidth test of Aida64, the read, write and copy of 1 × 16GB are 47603MB/s, 39159MB/s and 42515MB/s respectively; At 2 × 16GB, it is 88221MB/s, 77960MB/s, 79600MB/s. In addition, in the 7zip benchmark, 1 × 16GB scored 128.229GIPS, and 2 × 16GB scored 157.153GIPS.
Summary: As for whether a single 16GB of memory in the game book currently affects the performance of daily applications, the conclusion from our comparative measurement of the Tianxuan 5 Pro is that the common daily applications, including the game performance, have little impact on the performance of the game. There is no need to worry about it, and it is more convenient for users to upgrade later, which has many benefits. So the overall conclusion is that if you don't have the application demand for special memory capacity, you can buy a game book such as Tianxuan 5 Pro without upgrading the memory for the time being, and properly meet the regular use demand.
Of course, if your daily heavy applications include video clips, 3D rendering, industrial design and other applications in addition to games, you can also spend 300 yuan earlier to upgrade a 16GB memory, or even 600 yuan to upgrade a 32GB memory for emergencies.
The above is our comparative measurement of different memory configurations of the Tianxuan 5 Pro. Is there any surprise about this result? Welcome to leave a comment~
