This article mainly explains "how to choose a win7 computer". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn how to choose a win7 computer.

Matters needing attention before purchase:

1. Set a budget: do as much money as you want

Before choosing and buying notebooks, you should first confirm the purchase calculation, and confirm the scope of purchase according to your own demand for computers and economic situation.

two。 Fixed use: what is the purpose of buying a laptop?

Computers can roughly be weighed and confirmed according to their use, preferences, and appearance. For example, if you are a design major, you will have better color requirements for computers than others, so you need a screen with better color performance; if you are in the construction industry and usually need a lot of graphics, you need a better processor. Therefore, be sure to know in advance if there are any special needs for your computer in your usage scenario before you buy.

3. Tradeoffs and compromises: priority is the key!

Suppose I am a game enthusiast, hope to buy a notebook that can play mainstream large games, it is better to be a little thin and convenient to take home during the holiday, hoping to have a cool appearance. Then I will simply sort it according to the importance of different needs.

(1) High performance, priority i7 processor with high performance graphics card, preferably solid state disk and large memory

(2) appearance, it is better to have a better appearance or design or color, etc.

(3) easy to carry, it is best to consider notebooks with light and thin 1.8kg or suitable size.

As a game book, ensuring smooth game performance is the most important requirement, so it has the highest priority. Other importance decreases in turn. When the limited pre-selection can not be fully met, priority should be given to meeting the previous needs. After choosing according to your needs, I'm sure you already know what kind of laptop you need.

Computer purchase Guide:

1. CPU

1. The first four-digit number 6 refers to the intergenerational, that is, Intel's 6th generation processor. At present, the fourth, fifth and sixth generations of processors coexist on the market, and processors older than the fourth generation are now relatively rare and generally not recommended.

two。 The four digits followed by three digits of 920 are its SKU values, which are used to distinguish CPU models with different performance. In general, the larger the number, the higher the performance.

3. The letter H followed by the number represents the power consumption / performance category of the processor, similar to U (ultra-low power 15W), M (only five generations ago), and H (high performance 35W/45W). It should be noted that high power consumption not only means greater power consumption, but also means greater calorific value of the CPU. And then the notebook cooling system has higher requirements, so focus on high-performance notebooks (such as game books), there are few thin, long-lasting.

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

Second, graphics card

As shown in the figure, GTX960M,9 stands for algebra, with the latest being 10, such as GTX1060. The last two digits represent grades, usually from 10 to 90. The larger the number, the stronger the performance, and the higher the power consumption. The suffix M means optimized for laptops (performance is lower than the desktop version, so power consumption and heat are lower). This year, NVIDIA also added graphics cards with the MX suffix, which can be understood as a small change, and its performance is slightly better than the M version. Similar to CPU, the higher the performance of the graphics card, the higher the power consumption and calorific value. In addition to the model, the notebook video memory is also a hot spot of attention and sales.

In addition, many notebooks are not equipped with independent graphics cards, but directly use the core graphics cards integrated on the CPU (kernel display), which is characterized by power saving.

III. Memory

With regard to memory, you only need to pay attention to three parameters: the capacity of memory, the algebra of memory, and the frequency of memory.

At present, the most common notebooks are DDR3 1600 (third-generation DDR memory, frequency 1600MHz), DDR4 2133 and DDR4 2400. The former is more common, while the latter is the trend of future development.

At present, there are two main types of notebook memory. One is the conventional memory slot, and the second is the memory particles solidified on the motherboard. The main difference is that the former can be upgraded and the latter cannot be upgraded. The former also needs to pay attention to the number of memory slots. Some low-equipped models may have only one memory slot or there may be a combination of motherboard solidification and memory slots. For details, you can contact the official after-sales query to confirm.

Fourth, hard disk

The main types of disks are mechanical hard disk, hybrid hard disk and solid state hard disk, and there are three common combinations:

1. Pure mechanical hard disk (usually 500g or more)

two。 Dual hard disk (solid state + mechanical)

3. Pure solid state drives (common 128g, 256g and 512g)

Because it is generally accepted that the mechanical hard disk is the last performance bottleneck in the computer hardware system. So unless your budget is particularly tight, it is strongly recommended that you add (change) solid state drives. At present, the fastest SSD on the market is the SSD of PCI-E X4, which supports NVMe protocol.
