Fixed budget
The first step in choosing a laptop is to determine the budget, without a budget in mind, anything else you consider is pointless. It is recommended that you set a maximum budget, for example, $400, and then reduce the price by $100 from this maximum budget, that is, start choosing at the $300 price point. Why do this? When choosing a laptop, among a bunch of laptops with similar budgets, if one comes up with one that is better equipped and more attractive, but more expensive, it is easy for a person to forget about the initial budget and choose the more expensive option.
Choosing the right type of laptop
Next, let's talk about the types of laptops.CPU, Graphics Card, RAM, Hard Disk ......Doesn't this hardware configuration sound a little hard to understand? Don't worry, I'll explain them one by one.
CPU, that is, the central processing unit, it is like the computer's "brain", processing data in the computer, a powerful CPU, is to ensure that the laptop good experience of the basis;
Graphics card is responsible for the task of graphics computing, mainly affecting the game and some of the software that requires graphics card computing experience, such as Pr, local AI model, and some 3D software;
Memory is mainly used to temporarily store CPU data and exchange data with the CPU, which can also affect the daily experience;
Hard disk can permanently store data, which directly determines how much can be loaded inside the computer;
The monitor mainly plays the role of displaying the screen, the laptop comes with a screen, the good and bad of this screen directly determines the comfort level of your eyes;
The motherboard carries a variety of hardware, desktop need to pick the motherboard, but laptop computers basically do not need to pay attention to the parameters of the motherboard, pay attention to the computer comes with the interface is more important;
The power supply is mainly to play the role of AC power to DC, to the role of the computer power supply, the power supply of the laptop is an adapter, the game of the book need to pay attention to the power of this adapter;
Battery affects the duration, if you have high requirements for the duration of the laptop, it is recommended to prioritize the large battery models.
Select Configuration
Now, let's dive into the details of your configuration.CPU, graphics card, RAM, hard disk ...... Each of these has a direct impact on your experience. How to choose the right graphics card for your needs, and why the capacity of your RAM and hard disk are critical.
First is the CPU, how to see the CPU performance strength? The first is the process architecture of the CPU, which is the main test of the design and manufacturing capabilities of chip makers and foundries. the more advanced the process architecture of the CPU, the more transistors can be integrated into the same size of the CPU chip, thus enhancing performance and efficiency.
With the same process technology, it's all about specifications. The more cores you have, the better the performance. In addition, there's Hyper-Threading technology, which allows a core to run multiple task lines at the same time, improving the CPU's multitasking performance.
The same process, the same number of cores, the higher the main frequency, the CPU can execute more instructions per second, the faster the computing speed. But the main frequency is not the higher the better, the laptop also need to take into account the heat and endurance, so now the CPU are supported by the RWD technology, usually running at a lower frequency, when necessary, automatically raise the frequency to a higher value, to ensure the endurance and performance.
Finally, cache, cache is a fast storage area inside the CPU, the bigger the cache, the faster it is, which can reduce the waiting time for the CPU to access the data and improve the performance performance. For games, the CPU needs a lot of real-time computing, if the cache is not large enough and fast enough, the graphics card needs to wait for the CPU, the frame rate will decline, so for gamers, you need to choose a product with a large cache and high speed cache.
Next is the graphics card. The factors affecting the performance of a graphics card are similar to those of a CPU. First of all, the process architecture, in the same size of the GPU chip integrated more transistors, naturally stronger performance, followed by specifications, the GPU chip has a lot of stream processors, the same process architecture, the more stream processors, the stronger the performance.
Then there's the graphics memory. The bit width of the graphics memory and the graphics memory have a great impact on the performance of the graphics card, first of all, the graphics memory bit width, the GPU chip and the graphics memory need to interact with the data, and the bit width represents the width of the interaction channel, the wider the channel, the faster the data transfer speed; graphics memory capacity represents the amount of image data that can be processed at the same time, the bigger the memory, the more powerful the performance. Note that both memory capacity and bit-width are very important, if only one of the parameters is beautiful, the performance improvement of the graphics card, are relatively limited. Large video memory needs to be matched with a large bit width, you can't have one without the other.
The last is the frequency, like the CPU, the higher the frequency of the graphics card, the faster the speed of processing image data, the stronger the performance.
Laptop memory comes in two forms, on-board memory and standalone memory. On-board memory is memory that is integrated directly into the motherboard and cannot be upgraded or replaced, but this type of memory tends to have more performance;
standalone memory is connected to the motherboard through a memory slot and can be upgraded or replaced, and the performance is usually not as good as on-board memory.
There are four main factors that affect memory performance. First is the capacity, if the memory is insufficient, it may lead to software lag, slow loading game scene switching, etc., so the priority is to consider the capacity; second is the frequency, the frequency mainly affects the memory read/write speed, the faster the memory read/write speed, the stronger the performance; then followed by the number of channels, the laptop is generally a dual-channel memory, a very few have a four-channel, the more the channel, the more the memory can be at the same time to carry out data transmission, which can also improve performance; finally, the timing is the number of channels. Can also improve performance; Finally, timing, timing is a set of parameters reflecting the memory reflection time, the lower the timing, the lower the latency, in some high-frame-rate online games, the lowest frame of the performance of the better, the view is more fluent.
Next look at the screen, how do you measure the quality of a laptop's screen?
First of all, the resolution, the resolution determines the clarity of the screen, the higher the resolution, the finer the screen; followed by the color gamut, the color gamut mainly determines the display screen to show the richness of the degree of color, the wider the color gamut, the richer the color. Currently the mainstream high color gamut screen is 100% sRGB, there is a wide color gamut screen is 100% DCI-P3, P3 color gamut is wider than sRGB color gamut.
For shooter gamers, the refresh rate is important, high refresh rate screen can improve the operation of the degree of agility, other computer users do not need to pursue high refresh rate.
Then is the brightness, brightness is generally expressed in nits, the higher the brightness, the clearer the bright light environment.
Finally, color accuracy, professional retouching, film cutters need to pay attention to, color accuracy with △ E, △ E, the smaller, that is, the smaller the deviation from the color, the higher the color accuracy.
