Which one is better, one DDR5 memory or two DDR5 memory?

These days, the game circle is so lively. Intel Intel officially released the 13th-generation Core mobile processor, NVIDIA officially released the RTX 40 series notebook computer graphics card, and a large number of game books combined by strong alliances have been launched. As the first brand of Shenzhou and Mechanical Revolution to be listed on the market, it launched a “strong medicine” as soon as it came up, and the initial price of the game notebook equipped with RTX4060 was as low as 5,999 yuan. “It’s powerful, that is, stacking and volume prices.

However, judging from the configuration of the new batch of gaming notebooks, many gaming notebooks are equipped with DDR5 memory, but not two, but only one. Some friends may wonder whether a DDR5 memory has any impact on performance? Today we will analyze this problem.

The test result of a DDR5 memory

Using AIDA64’s memory and cache test program to test a DDR5 memory, the reading speed of the memory is 39229MB/s, the writing speed is 34301MB/s, the copying speed is 36047MB/s, and the delay is 85.7ns.

Test results of two DDR5 memory

From the results, the measured reading speed of two DDR5 memories is 50280MB/s, the writing speed is 55071MB/s, the copying speed is 48573MB/s, and the delay is 85.2ns.

It can be seen from the comparison results that the performance of one DDR5 memory is obviously weaker than that of two DDR5 memories. Not only the reading speed and writing speed have declined, but even the delay is slightly higher than that of two DDR5 memories. leave.

Let’s take a look at the two DDR4 3200 memory test results

It can be seen that the reading speed of the two DDR4 3200 memory is 39154MB/s, the writing speed is 32466MB/s, the copying speed is 34683MB/s, and the delay is 98.8ns.

In comparison, the performance of one DDR5 memory is almost the same as that of two DDR4 3200 memories. In other words, if you buy a gaming laptop with only one DDR5 memory pre-installed, then the memory performance is equivalent to two DDR4. It can be seen that the advantage of higher frequency of DDR5 memory is not reflected at all.

And at this stage, there are not a few people who use a single DDR5 memory. The main reason is that the capacity of a single DDR5 memory can easily reach 16GB, unlike DDR4 memory, where the common capacity of a single memory is 8GB. In gaming notebooks, the capacity of a single memory is getting bigger and bigger, and 16GB memory is already the mainstream, so many manufacturers only install a DDR5 memory.

Purchasing suggestion: If you happen to plan to buy a gaming notebook in the near future, and your favorite gaming notebook has only one DDR5 memory, and you have a demand and sufficient budget, then it is recommended that you purchase another memory with the same frequency and install it in the gaming notebook. In this way, the capacity of the memory is doubled, and the performance will also be greatly improved. After all, memory is an important factor determining the performance of the current computer. All applications run in the memory. Enough memory can allow us to use the computer smoothly. And a large capacity of memory can better meet the needs of use.

It is worth noting that the installation of memory needs to be disassembled. If you disassemble the computer yourself, there are certain risks, such as broken or not disassembled, and may also affect after-sales service. Therefore, for this type of users, it is recommended to go directly to the official after-sales service after purchasing the memory, so as to avoid some unnecessary losses, but the disadvantage is that some manual fees will be charged, and the cost is about 100 yuan.

Finally, let’s go back to our question at the beginning, whether a DDR5 memory has any impact on performance, the answer is definitely yes. At the same time, it can be seen from the comparison of the test results that the difference between one DDR5 memory and two DDR5 memories is very obvious, and it is equivalent to two DDR4 memories. Therefore, if some applications are sensitive to memory performance, the disadvantage of a DDR5 memory will be reflected.
