How does Xiaobai start the first laptop?

Many white people come to me to recommend notebooks. Think about these years, contact more, deeply feel that there are really many pits here. There are still many friends who don't understand the market. It is also a very tragic thing to be cheated in buying books. Therefore, I would like to take this opportunity to provide you with an idea of purchasing notebooks.

1. Determine the budget

Of course, the stronger the computer configuration, the better, but usually there is a rough upper limit for error-free owners, and laptops beyond this upper limit will not be considered. After all, not everyone is short of money. So my friend asked me to recommend a notebook, and the first sentence I said was usually: "What's the budget?" Don't change the budget easily after it is fixed, otherwise it will be difficult to choose after it is fixed. Because it is the first notebook, there is no need to set the budget too high and do what you can.

Understand the needs

After solving the problem of money, there is a more annoying question: "What do you need for a notebook?" Your personal preferences, such as thinness, high performance and playing games, are well known to everyone. However, people often overlook another point: what you often do often requires a notebook. For example, art design requires higher color, so it needs a screen with better color performance; The financial accounting major needs a keyboard, but only notebooks larger than 15 inch will have a keyboard and so on.

This is the 14 inch screen notebook I chose for my friend before, and there is no keypad. So you need to know in advance whether your job has any special needs for computers. Fortunately, the internet is very developed now, even though I haven't entered school yet. You can also easily get it from various sources. Ask them, and this part will be easy. This will give you more time. In addition, there are large-scale promotional activities such as Shuang 1 1 and Shuang 12, which is also a very good time to start a notebook.

Step 3 weigh and compromise

People's desires are endless, but money is limited. To meet your needs as much as possible with limited money, you need to arrange your needs at an important level. Suppose I'm doing photography in art college, and I want to buy a notebook that can be edited later, preferably light and portable. Then, I will simply sort the different requirements according to their importance, like this:

At least 1080P wide color gamut screen.

Run Photoshop with at least 8G memory.

The weight shall not exceed 1.8kg, and the thickness shall be within 2cm as far as possible.

Support electromagnetic pen, which is convenient for Lightroom to use.

As photography, it is definitely the most important to ensure the accurate presentation of colors, so it ranks first. The importance of others decreases in turn. When the pre-selection is limited and cannot be fully met, the previous demand is given priority. After completing this step, I believe you already know what kind of notebook you need.

There is a saying that if you want to buy things in China, you must first become an expert in this field. Although this statement is somewhat helpless, it is true in a sense. The so-called "know yourself and know yourself, and you will win every battle." After knowing your own needs, the next step is to know something about notebooks.

1. What do you think of the CPU model?

The central processing unit is the core of the computer. Currently, the notebook market is basically monopolized by Intel's CPU. Intel's CPU model naming is quite regular, as shown in the following figure:

Take i7-6920HQ as an example. The blue part is the model of the processor series (i7, i5, i3, I believe everyone knows). Focus on the green part:

The first number of the four digits is 6, which represents the first generation, that is, the sixth generation processor of Intel. At present, Intel has four, five and six generations of processors in the market. At present, there are very few processors with more than 4 generations, which is generally not recommended.

920 is its SKU value, which can be understood as a number. Used to distinguish CPU models with different performances.

The letter followed by the number is H, which represents the power consumption/performance category of the processor. Similarly, there are U (ultra-low power consumption 15W), M (only appeared before the 5th generation) and H (high performance 35W/45W). It should be noted that high power consumption not only means greater power consumption, but also means greater heat generation of CPU. Furthermore, there are higher requirements for the cooling system of notebook computers. Therefore, notebooks that focus on high performance (such as game books) are few, thin and durable.

The last product line suffix includes Q (quad-core processor) and K (open overclocking). Dual-core, non-overclocking processors do not have this suffix, which is also the most common.

What? Still don't know how to choose after reading it? Simply put, if you care about power consumption (power saving), the more you update, the more you save. For example, the sixth generation saves electricity than the fourth generation. In the same generation, U saves more electricity than H, and H saves more electricity than HQ/HK. This is easy to understand.

And if you want to know the performance, this is a bit troublesome. For example, i7 & gti5 & gtI3 is basically unreliable. Because this statement only holds true under the same generation of processors and the same power consumption level. It is difficult to understand that the performance of i5-6300HQ is better than that of i7-6600U, i3-6 100H, i7-46 10Y. Therefore, it is really unreliable to judge the performance only by the model. For the sake of convenience, I recommend a convenient (but not completely rigorous) method: check Passmark score.

Passmark score can represent the performance level of the processor to a great extent. The higher the Passmark score, the stronger the CPU performance, which can be used as a reference for everyone to buy. If you don't have any ideas, according to my own experience, a Passmark score of around 3000 can ensure the basic fluency of surfing the Internet, working and watching full HD videos. But again, this score is only a simple basis for judging and buying, and it is not completely rigorous.

In addition, since 20 15, Intel has launched the Core M series processor, focusing on the ultra-low power consumption (4.5W) without fan cooling. The naming rules of M series are similar to those of I series. I believe everyone can learn by analogy, so I won't go into details here.

2. What do you think of the graphics card model?

Similar to Intel, most discrete graphics cards on notebooks come from NVIDIA. However, in contrast, the naming of NVIDIA graphics cards is much simpler, as shown in the following figure:

The green part in the middle is the model we often say, 960M m. Among them, 9 is intergenerational, that is, the ninth generation NVIDIA graphics card. At present, the notebooks on the market are mainly 9 series, and there are also a certain number of 8 series.

The last two digits represent the grade, generally from 10 to 80. The bigger the number, the stronger the performance and the greater the corresponding power consumption. The suffix m means optimized for notebooks (performance is lower than the desktop version, so power consumption and heat generation are lower). This year, NVIDIA also added a graphics card with MX suffix, which can be understood as a minor change, and its performance is slightly improved compared with the M version. The prefix of GTX is only available for graphics cards above 850M and 950M, which is a representative of high performance. Similar to CPU, the higher the performance of graphics card, the higher the power consumption and calorific value.

In addition to the model, the memory of the notebook is also a very big pit. Many manufacturers will use low-end graphics chips with large memory, such as:

Macro? (Acer) K50 15.6-inch notebook computer (i5-6200U 8G 1T 940M 4G single monitor turned off and charged with full HD screen win 10)

This combination is very charming. In fact, allocating large memory to low-end graphics cards will not substantially improve game performance. So as long as the memory capacity is appropriate.

In addition, many notebooks are not equipped with independent graphics cards, but directly use the core graphics card (nuclear display) integrated on the CPU, which is characterized by power saving. Generally speaking, the nuclear display on the notebook can meet most of the daily needs, and you can also play online games by turning down the special effects. But I still feel reluctant to play games happily. However, correspondingly, because the nuclear display is very power-saving, the battery life of notebooks without a single display screen is generally slightly longer, making it easier to be light and thin.

3.will 3. AMD works?

Having said that, friends who pay a little attention to the PC industry will ask: how can my big AMD be ignored? As an important CPU and graphics card manufacturer. AMD still has a certain weight on the desktop. On the notebook, although Intel and NVIDIA are almost absolute monarchs, AMD can be seen occasionally. For example:

Hp Probook 455G3 15.6 inch business ultra-thin notebook computer (a10-8700p4500g r8 m350dx2g stand-alone Win 10)

An HP notebook, AMD processor+graphics card, also known as 3A combination. The embarrassment of AMD processor is that it uses an old process of 28nm, which is two generations behind Intel's latest 14nm process. Performance and power consumption are far behind by Intel processors. For an extreme example, the performance of Intel's m7-6Y75 processor is similar to AMD's A 10-8700P, but the power consumption of the former is only1/5 of the latter (7W versus 35W). Of course, this example is a bit extreme, because AMD's nuclear display is much better than Intel's.

Lenovo m4 1-70 14 inch IPS commercial ultra-thin notebook with wide viewing angle screen (I5-5200U 4G 128G solid-state 2G fingerprint recognition).

A Lenovo notebook with Intel processor and +AMD graphics card. To tell the truth, this type of notebook left a great psychological shadow on me. Several friends around me are using this I+A combination notebook, and most of them have encountered the problem of graphics card driver. Once I helped one of them install the system, the graphics card could not be driven anyway, and the blue screen was repeated. In a rage, the independent display in the BIOS was turned off, and the nuclear display was only Intel. The system is stable. AMD's drive stability is really catching chickens.

Grinding a Sword in Ten Years: AMD 14nm FinFET; A new generation of X86 micro-architecture Zen processor supports SMT multithreading, and the performance of single thread is greatly improved. Many experienced DIY players have great feelings for AMD processors, such as its classic K8 architecture and representative product AthlonX23800+, which can be said to be the most successful CPU in AMD history, and it is ahead of the "glue dual-core" PentiumD in power consumption, performance and efficiency. But the short-term advantage was surpassed by the appearance of IntelCore2 processor in 2006.

Although AMD doesn't live up to expectations on mobile platforms, I still like AMD. Recently, AMD officially launched the ZEN architecture. Whether AMD will re-emerge and whether 360 will turn over is still unknown. However, you won't see ZEN architecture processor appear in your notebook in a short time. Therefore, based on rational judgment, I don't recommend you to buy any notebook products related to AMD.

4. About memory

Compared with CPU and graphics card, memory is really much simpler. Generally, we only need to pay attention to three parameters: memory capacity, memory generation and memory frequency. Capacity is easy to understand, and it may be necessary to briefly mention the generation and frequency. At present, there are DDR3 1600 (third generation DDR memory, frequency 1600MHz) and DDR42 133 (fourth generation DDR memory, frequency 2 133MHz) commonly used in notebooks. The former is more common, and the latter is the trend of future development.

ASUS X20 1e notebook, the memory of which is welded on the motherboard, cannot be replaced or upgraded. In fact, compared with these parameters, I will pay more attention to the memory upgrade space of the notebook. Early notebooks generally had two memory slots (one occupied and the other reserved), which was convenient for users to upgrade their own memory. But now many notebooks are based on commercial considerations, or to make notebooks thinner. There is only one memory slot, or the memory is directly soldered on the motherboard. It is very difficult or even impossible to improve memory.

Then why add your own memory? The reason is simple: cheap. Now a 4G notebook memory is about 120 yuan. However, domestic notebook manufacturers often regard 8G memory as a kind of existence that distinguishes grades. Take the ThinkPad E450 of the Bank of China as an example:

Lenovo thin series E450(20DCA082CD) 14 inch notebook computer (i5-5200U4G500G2 single display win 10)

The 4G memory version of E450 is now 3699 yuan, and the 8G version of 600 yuan is more expensive than robbery. If you can upgrade your own memory, you can save 480 yuan. It is generally believed that 4G memory is basically enough, and 8G memory is more plentiful. Within the budget, it makes sense to go to 8G memory. If the budget is limited and you want to use more than 8G of memory, you can give priority to notebooks with reserved memory slots.

5. About the hard disk

In the early years, notebooks were mainly mechanical hard disks. Choosing a hard disk is simple, 500G or 1TB. Pay attention to speed and cache size. However, in the past year or two, solid state drives have sprung up everywhere. Compared with mechanical hard disk, the reading and writing speed of solid state hard disk, especially the random reading and writing speed of small files, has been greatly improved. The performance advantage is obvious, so it has also begun to be popularized in notebooks. There are four common hard disk combinations in notebook computers:

Pure mechanical hard disk (generally 500G or 1TB)

Hybrid hard disk SSHD

Double disk (solid+mechanical)

Solid state hard disk (normal 128G, 256G and 5 12G)

Among the four schemes, except the hybrid hard disk, it is not worth buying (the actual performance is very different from that of the pure mechanical hard disk). The other three can be considered. However, it is worth noting that the 1 model is generally recognized that the mechanical hard disk is the last performance bottleneck in the computer hardware system. So unless your budget is particularly tight, I strongly recommend that you add (modify) a solid-state hard disk after buying a pure mechanical hard disk. There are three corresponding upgrade schemes:

There is a good saying in the preface of SSD: if the computer is repaired well, the spare tire will be old. I don't know when the business of repairing the computer shop downstairs was transferred to me. Maybe it's because I'm better and more skilled, and more likely it's because I don't charge money. A few days ago, I received a sister's help, saying that the notebook system was not started correctly. A simple inspection shows that there are too many bad tracks on the hard disk. But this notebook uses a 7mm thin disk. If you want to change the mechanical hard disk, there are not many options.

The first type: directly remove the mechanical hard disk and replace it with a solid-state hard disk. The replaced hard disk can be used as a mobile hard disk. After modification, it is equivalent to a pure solid-state hard disk. This scheme has the best performance in theory and is suitable for friends who have little demand for hard disk capacity.

Another attempt of low-cost TLC solid state: LITEON Jianxing Su Zhi 240G solid state hard disk unpacking &; A brief comment on the preface the other day, do you believe in chairs? Start sneaking into the old one? Class a solid state drive. It seems that SSD is really becoming popular. The demand of friends is about 240G, as long as the performance is stronger than that of machinery. Life doesn't matter much, just let the notebook be used for another two years. Therefore, the TLC solid state of cheap big bowl is naturally suitable.

Second: If the notebook has an optical drive, you can remove the optical drive. Install the mechanical hard disk of notebook computer to the interface of CD-ROM drive with the hard disk bracket of CD-ROM drive. The newly bought SSD can be installed in the position of the original mechanical HDD. After the transformation, it is equivalent to the solid-state+mechanical dual-disk scheme, which takes into account the requirements of high performance and large capacity.

The third type: now many notebooks with new molds will reserve an mSATA or M.2 interface on the motherboard. As long as you buy a solid-state hard disk with corresponding specifications and install it, you can realize solid-state+mechanical dual disk. The effect is the same as the second scheme. But it's easier without disassembling the CD-ROM drive. But only some notebooks will have reserved interfaces. So you'd better ask customer service before buying. It will be more secure if we can find the disassembly diagram of the same type of notebook.

Regarding the purchase of solid-state hard disks, if you want to expand, it is a great knowledge. I won't go into details here. Again: As long as you don't want a computer card, a solid-state drive is necessary.

6. Screens that you might ignore.

Screen is the most important bridge between notebook and people, but it is also the most easily overlooked. The screen size is hard to say. Small sizes such as 12.5 and 13.3 are more convenient to carry, while large sizes such as 15.6 and 17.3 can bring better audio-visual entertainment experience. This can be selected according to personal needs.

Another important indicator of notebook screen is resolution. The higher the resolution, the better the screen display accuracy. The picture above shows several common screen resolutions. In addition to these conventional resolutions, many different resolutions are derived, such as 1440900(MacBook Air), 3200 1800(QHD+, commonly known as 3K screen), 30002000(Surface Book) and so on.

In particular, the resolution of 1366768 should be mentioned. At present, the domestic notebook market is still full of 768p resolution screens (especially low-end notebooks). This resolution has been used for a long time, and it is really out of date today when the mobile phone screen is 4 K. Similarly, unless the budget is limited, I suggest you choose at least 1080p notebook.

ASUS) Vivobook 4000 15.6-inch notebook computer (i7-5500U 8G 1TB 2G Bluetooth Win 10 black UHD IPS 4K screen)

Of course, the higher the screen resolution, the better. The higher the resolution, the more calculations the CPU and graphics card need to undertake. For example, the ASUS notebook above, the combination of i7-5500U+940M is not high-end. However, it is directly equipped with a 4K resolution screen, although there will be no problem in daily use. But if you want to play games with it, I'm afraid it will be very difficult. At present, few game books have a resolution higher than 1080p, which is also the reason.

Finally, the color gamut and viewing angle of the screen are the most easily overlooked. Color gamut refers to the collection of colors that can be displayed on the screen. The wider the color gamut, the brighter the screen and the stronger the color expression. The viewing angle is the range of angles where the screen can be clearly viewed. In fact, these two indicators have a great influence on the look and feel of the screen, but it is difficult for ordinary users to detect it without comparison. Therefore, these two indicators are easily overlooked.

The screen, color gamut and viewing angle of this low-end Dell notebook are not so good. The screen with the resolution of 1366768 is basically not as good as the display effect. This is also an important reason why I don't recommend you to buy a 768p screen notebook. Of course, it does not mean that the 1080p screen must have a good display effect. There is a simple (but not necessarily reliable) way: watch advertisements!

The promotional copy of ASUS ZenBook U305FA mentioned a wide color gamut and a wide viewing angle. The promotional copy of notebook manufacturers is just like the PPT of mobile phone conference: what you have is sure to be praised. The cost of screens with better color performance is quite high, and manufacturers will naturally not miss this promotion opportunity. Generally speaking, a screen with wide viewing angle and 72%NTSC color gamut (about 95% sRGB color gamut) is not too bad. At least in the notebooks I have touched, this rule is effective. Many majors have high requirements for color, such as photography and art design. If you are in these majors, it is recommended to give priority to the display effect of the screen.

7. Valuable industrial design

Asus ZenBook U305FA, its 12.3mm extreme thinness is what I am most satisfied with Recently, various notebooks with excellent industrial design have emerged one after another. For example, the shocking narrow screen frame XPS 13, the Surface Book that breaks through imagination and so on. Although the excellent design is not as intuitive as the above parameters, it can really bring a more pleasant experience in use. This improvement in experience is difficult to quantify, but it is perceptible in use.

On the other hand, better design and workmanship are "valuable". This means that notebooks with excellent industrial design will be more expensive than other notebooks with the same configuration. Whether the money is spent well or not depends on yourself. But my suggestion is that in the case of ample budget, priority can be given to paying for better design. When the budget is tight, it is necessary to ensure smooth and meet the needs.

In fact, there is too much knowledge in the purchase of notebooks. Now, only these seven points are extracted, which is the key point that Xiaobai will consider when purchasing notebooks. With these knowledge reserves, coupled with the understanding of their own needs and budgets. You can start shopping!

Purchase actual combat

Let's take JD.COM as an example. First, we turn on JD.COM's notebook channel and choose the self-operated option. Everybody pay attention to screening. In short, find "self-employment".

At the top of the page, there is a shocking filtering tool. You can filter according to your own budget range and needs. It is recommended that you do not screen brands when screening for the first time. Because no matter who you hear about a brand, positive/negative comments. This view is likely to be very one-sided. Now there are hundreds of products under a manufacturer, among which there must be essence and dross. Like I used to, I don't particularly like Lenovo, but in recent years, Lenovo has indeed launched many boutique models in China. Let me change my view of Lenovo.

In addition, it is not recommended that you filter two: the operating system (no matter what system comes from the factory, just buy it and install it yourself) and the memory capacity (notebook rarely has the problem of insufficient memory). Others can filter according to the requirements summarized above.

If you don't meet your needs in the final budget. It is necessary to consider compromising some small demands, saving the country by curve (for example, considering adding memory for saving money in solid state), and raising the budget appropriately. If you are an advanced player, you can also consider Haitao. In short, the idea is to give priority to meeting major needs.

If you have any questions. Also welcome to communicate with me in the comments. Like my article, don't forget to like or pay attention to it.
