September 1st is approaching, and millions more students will enter colleges and universities, into their long-awaited university life. Choosing a laptop for study is one of the important preparations for their start of school, so how to choose a notebook that suits you?
It is believed that most of these students will choose to buy from e-commerce channels such as Jingdong, Tmall, and manufacturers' official websites, on the one hand, it saves time and effort, and there are also preferential prices; In addition, the e-commerce platform has a rich variety of products, which is convenient for comparison and selection; In addition, you can check the experience of the purchaser from the evaluation.
However, in the e-commerce detail page, all the details of the laptop will not be displayed one by one, but targeted publicity made by the manufacturer according to product positioning and selling points. Many details will not be mentioned, and even hidden in a "targeted".
Below, the editor will sort out some hidden knowledge points of some selected books, which even ChatGPT may not know!
Is dual-channel memory having a big impact on performance?
Dual-channel memory technology is not a new technology, so many manufacturers may not have much publicity in the publicity. When performing some procedures, the dual-channel technology has great advantages.
Simply put, dual-channel memory technology is to double the bandwidth by using two memories, so that performance can be improved, and the advantages are mainly reflected in applications such as graphics processing, video editing and games.
At present, the mainstream new notebook memory starts at 16GB, and most of them use a single 16GB memory, so users cannot experience the performance improvement brought by dual-channel memory technology.
Therefore, before purchasing, you can confirm whether the notebook supports memory expansion, if there are 2 memory slots, you can buy another 16GB memory of the same type, so that you can experience the performance improvement (part of the performance improvement comes from the increase in memory capacity).
However, in order to pursue thinness, some laptops use onboard memory, so that users cannot upgrade operations, so friends who want to upgrade must consult customer service.
In addition, to add a knowledge point, PConline has done some research, in addition to individual notebook products, most notebooks if disassembled on the grounds of "upgrading memory", even if they are new, they will not affect the warranty policy, you can rest assured.
Focus only on resolution, ignoring screen materials and color gamuts
In the introduction of e-commerce, manufacturers may use large fonts and bright colors to impact your vision to attract your attention, but after careful observation, you will only find that there will only be 2.5K, 2.8K (high resolution), and 120Hz high brush, but you can't see any introduction to the screen material, because it only uses IPS material, not OLED.
The above illustration is for illustrative purposes only and does not represent any product
Compared with IPS, OLED has better color accuracy, response speed, color gamut coverage and other advantages, and the screen brightness will be higher. Generally, IPS is around 400 nits, while OLED can reach 600 nits, and the advantages are obvious.
The picture above is from Zhihu@Humu
In addition, many notebook screens use sRGB color gamut, but in fact, sRGB is only a relatively basic one, as shown in the figure above, and there are color gamut standards such as P3 and Rec2020 with a wider color range.
Fan noise, escalated to "pollution"
In the promotion of many game books, manufacturers will use various numbers to promote the heat dissipation capacity of the product, such as fan speed / number of air outlets / number of heat pipes / number of heat dissipation fins increased, how much heat dissipation capacity has increased, etc., and will also show the body temperature under full load operation, which can facilitate everyone to understand the heat dissipation of the game book.
However, there is a problem that cannot be ignored is the noise caused by the fan, the noise of individual game books is intolerable, even if it can have a good heat dissipation performance, but the "noise pollution" caused by excessive noise can definitely not be ignored.
As far as the experience of Xiaobian is concerned, the problem of excessive noise mainly appears in some second- and third-tier brands, if you are more concerned about the impact of noise on the experience, it is recommended to check more reviews and reviews before purchasing.
Power adapters help you work out
This situation is also mainly focused on gaming products, which provide users with better performance, so larger adapters are also needed to meet the release of performance.
Taken from JD.com user reviews
This is an unavoidable problem, so it can only be recommended that you can roughly evaluate whether you can accept a larger and heavier power adapter before buying a game book, especially when you choose an RTX4080/4090 level game book, when it provides more powerful performance, the power adapter will theoretically be larger than the RTX4070/4060/4050.
Brief summary:
In addition to the above, there are many aspects that cannot be understood through the "online" form: the trackpad is not as big as possible, and it is easy to touch by mistake; The keyboard has short key travel, which makes long-term typing feel uncomfortable; The visual effect of the matte screen and the mirror screen is quite different, and so on.
Today, e-commerce channels make it easier for us to understand information and buy products, but they do lack some realism in the experience. You can go to PConline to learn more about the details of the products and the hot events in the technology industry.
Finally, I added: under the premise of limited budget, fish and bear's paw are not both, you should not expect "both, also, also", but find the "most suitable" in it, thank you for browsing, I hope it can help you in your purchase.
