In the era of e-commerce, the product detail page is the primary way for ordinary users to understand the product, but even if the formal platform, it is still common to deliberately conceal exaggerated or unintentionally cause misunderstanding of the publicity copy, which leads to many consumers to find that the product is far from the expectation, so this year 3 · 15 for everyone to take stock of the common 7 major misunderstandings in the past year, to help everyone accurately avoid pits, it is easier to choose their own satisfactory products.
Myth 1: The i7 must be much stronger than the i5
The processor is the core of computing power in a computer, and many people will pay more attention when buying a computer. Among them, the Intel Core series processor is the most mainstream choice on the market at present, and the naming rules of i3, i5, i7 and i9 are divided into i3, i5, i7 and i9 according to the grade from low to high. But what many people don't know is that these grade divisions actually can't 100% represent the level of performance.
That's because there are two types of Core series processors for mobile: low-power editions designed for thin and light notebooks, and high-performance editions for performance-level notebooks. Taking the 11th generation Core as an example, the significant difference between the two is that the low-power version adopts a 4-core design throughout the series, while the high-performance version has 6 or even more than 8 cores.
Specifically, if you compare the i5 and i7 with the high-performance version, the i7 with 8 cores and 16 threads can indeed lead the 6-core 12-thread i5 in multi-core performance, with an increase of nearly 30%.
But if you compare the low-power versions of the i5 and i7, the results are completely different. Since they all use a 4-core 8-thread design, the advantages of the i7 are only high frequencies of about 0.3GHz and more than 4MB L3 cache, and the performance gap between the two can be said to be minimal.
Moreover, compared with the low-power version of the i7-1165G7 and the high-performance version of the i5-11400H, the performance is 50% behind, and the i7-11800H has a completely double gap. It can be seen that the processor named i7 is not necessarily stronger than the i5.
Of course, this is not to say that the CPU performance of the low-power version is not good, in fact, the 4-core 8-thread is more than enough for most users' office entertainment, and even light online game use, and it can also bring longer battery life for thin and light costs.
However, it must be emphasized that if you are a high-performance user who often runs video rendering, engineering modeling, etc., you can't just make a decision with the name of i7, you must also pay attention to its specific model or core number. In addition, in terms of thin and light range, the model equipped with i7-1165G7 has no obvious advantage over i5-1135G7 in performance, and the price is generally 500-1000 yuan more expensive, and its own purchase value is not as good as that of i5.
Myth 2: The unique display performance must be stronger than the set display
Graphics cards are responsible for computer image processing, and also play a very important role in game performance and rendering performance. Graphics card performance is mainly determined by the GPU core, even so, but there are still quite a few manufacturers in the promotion of the wrong mistake, so that Xiao Bai mistakenly think that the single display must be stronger than the set display, or even larger video memory means better performance. But in fact, these so-called discrete graphics cards with large video memory are not necessarily more powerful than integrated graphics cards.
Today's 11th generation Core processor integrated Iris Xe graphics have been greatly improved than previous generations, with dual-channel high-frequency memory and good heat dissipation, running MOBA online games is no problem at all, and even on many productivity software also support rendering acceleration.
On the other hand, the MX330 independent graphics card, as can be seen from the ladder chart, its basic performance is even lagging behind the Iris Xe display, which is really "shielding the unique display to improve performance". From the ladder chart, we can see that the 11th generation Core must at least be paired with the MX450 level of unique display to get a more significant performance improvement, so we do not have to pay for those backward unique displays.
Myth 3: Labeling a low-blue screen can be more eye-catching
Nowadays, everyone uses computers to work and learn more and more frequently online, whether for their own use or for children, they will pay special attention to the eye protection problem of the screen. Regarding eye protection screens, the industry generally focuses on two major aspects: strobe and blue light. At present, notebooks generally use LCD screens, mainly DC dimming, and there are relatively few strobe problems, so manufacturers often focus on low blue light. So buy these notebooks marked with low blue light, must it be more eye-catching? Not really.
Carefully look at the instructions can be found that a considerable part of the model needs to manually open the anti-blue light software switch after the hand, in order to take effect, not opened is not able to play an eye protection role, we call this form of implementation for the software low blue light.
Why should you give the switch since the eye protector? Of course, because there are side effects. Its principle is to put a layer of warm color filters on the screen, in fact, it is similar to the effect of adjusting the night mode in the Windows, so that while filtering harmful blue light, the non-harmful blue light is also filtered out, resulting in the entire screen display color turning yellow, and the color accuracy performance is greatly affected.
Is there a solution that works out both? That is the corresponding hardware low Blue light technology. This technology reduces the proportion of high-hazard short-wave blue light of 415-455nm by migrating the peak wavelength of blue light, and achieves low blue light without affecting the color reproduction of the screen.
However, its cost is also relatively high, and it is currently only used in notebooks above 4500 yuan, so notebooks that usually use this technology will be clearly marked "hardware low blue light" in the literature, and the supporting Rheinland low blue light certification will also be specially marked "Hardware Solution".
Myth 4: Nominal battery life
Battery life is a very important indicator for mobile office scenarios, but it is difficult to quantify accurately, and different use scenarios are prone to relatively large deviations. Many less experienced users may refer to the battery life marked by the manufacturer, but it seems that looking around, almost every model claims to provide more than ten or twenty hours of battery life, which is obviously far from our actual experience.
Why is there such a difference? In fact, manufacturers do not have false labels, but they usually choose a set of tests that ordinary users will hardly use. The following is a very common test standard, the screen brightness of 150nit (about 50%), not connected to the network, full screen playback of 1080P local video. And our actual use is usually networked to play online videos, hang communication tools and other backgrounds, run multiple office software at the same time, and even use high brightness, the result is naturally the opposite.
So what should we use as a reference standard for endurance? First of all, you can check the relevant reviews, find the PCMark 10 modern office endurance test, the load of this test is also lower than the daily, but relative to playing local videos is still much more reliable, basically the test score and then a 30% discount is close to the actual battery life performance of the continuous office. If you really can't find it, you can only divide the local playback video battery life marked by the manufacturer by two, and get a rough judgment.
Myth 5: Nominal performance release
We know that due to the reasons of heat dissipation space, most notebooks cannot completely run the performance of the CPU and graphics card, that is to say, under the same configuration, there are differences in performance between different models of notebooks.
We usually use the power that can be achieved at runtime to distinguish the performance release of different notebooks, and gradually, some manufacturers have begun to cater to everyone's habits in the product detail page. However, it should be noted that most reviews will point out that the power consumption data will eventually stabilize when the notebook is double-baked for a long time (the CPU and graphics card are full at the same time), and the manufacturer's labeling method is sometimes not the case.
For example, the following model labeled 35W processor release and 25W graphics card performance release, first of all, it labels the value of PL1 (long-term turbo frequency power consumption), but this power consumption is not guaranteed to be maintained for a long time; secondly, these two power consumption are single baked data rather than double baked data, that is, only when one of the CPU and graphics card is under a low load, the other party can achieve such nominal data, which is also not in line with the actual use scenarios of most people.
Myth 6: Vague description of the fuselage material process
With the upgrading of consumption, the texture of the fuselage of the notebook has also become an important element for many users when purchasing a machine, but this is more difficult to summarize based on words alone, which can be said to be some "metaphysical" factors, so there have been many confusing publicity here.
For example, some notebooks with metal materials only on the A side also claim to be "metal bodies".
There are still many people who hear the CNC process on the feel very tall, in fact, the notebook shell put into the CNC machine tool to walk a circle can be called CNC drill cutting, the effect formed is the edge of a circle of bright edges, can only be regarded as a small embellishment of the appearance, the cost is not high.
There are also some that claim to "use the 3D integrated molding process", but only the A side uses the process in small print annotations.
The A/C/D three-sided CNC integrated molding process commonly used in high-end notebooks (such as MacBook, XPS, etc.) is completely different, regardless of the thickness of the fuselage, the seams of the shell, or the touch will be significantly better than a grade. In short, for the thin and light cost, the texture of the workmanship is even more "penny-for-money" than the configuration, and the low price may be able to buy the flagship configuration, but it is really difficult to buy the flagship workmanship.
Myth 7: Luxury Customized Edition
Today's notebooks generally provide 16GB + 512GB memory combination, and often do not provide a larger capacity version, there will definitely be users are not enough, just in some third-party stores, we can always see some "large memory customized version" models, the price seems to be cheaper than their own purchase and installation, many people are moved.
But personally, it has always been recommended that everyone buy such products. First of all, the store to help you upgrade, it is inevitable to unseal and dismantle the process, it is bound to affect the secondary sales of this machine, so while agreeing with the customized upgrade, it is equivalent to giving up the right to return the goods for seven days without reason; secondly, some sellers may use this way to deal with the store display machine, return and replacement machine, etc. according to the price of the new machine, after all, they are all unpacking machines, and users cannot distinguish; moreover, from some evaluations, the store's so-called upgraded memory hard disk, a considerable part of it comes from the third-line miscellaneous manufacturers. Performance and quality are difficult to guarantee, and it is really impossible to replace the first-line original accessories with these accessories.
However, the ability to do it yourself is really not strong, and what if you need to upgrade? We can buy our own regular and reliable accessories, and then consult the local official after-sales service station for upgrade and installation, and some product series may also provide related free services. If there are no relevant conditions, you can also find the nearest computer repair shop for on-site installation to avoid the risk of accessories being dropped.
