How to buy a good laptop? What details should be paid attention to?

Buy a well-known brand notebook mainly focus on its four major aspects: CPU, graphics, memory, hard disk. Because the famous brand of Notebook other aspects (screen, heat, sound quality, etc.) are doing a good job. And for some computers, perhaps their prices are very low, in the same configuration, than the brand is cheaper hundreds of or even thousands. They have the same configuration in large directions, but they can start with a small aspect, for example, the computer's screen, cooling system, wireless network card, keyboard, sound, optical drive, or directly to renovate the old devices and so on, so that buyers think they are taking advantage of, but in fact, they earn more than some well-known brand notebook sold more. So how to buy a good notebook computer? What details should be noted? The following small series for everyone to introduce you, a look at it!

Tools/raw Materials

Some cash

"CPU"

CPU, which functions mainly to interpret computer instructions and to handle data in computer software. In layman's terms, it is a computer running speed to see the CPU, so the CPU is a computer's soul and core. And the response CPU speed of the basis is the frequency, the higher the frequency, the CPU processing data faster. And the core frequency is when starting a running program, the processor will automatically accelerate to the appropriate frequency, and the original speed will enhance the 10%~20% to ensure the smooth operation of a program of technology. Here is the latest CPU performance ladder chart, and you can choose the CPU you want based on the performance comparisons in the diagram.

Common sense: Distinguish the meaning behind the CPU model, such as 4710M 4710HQ 4700U.

S is low power low-frequency, M represents mobile, p represents mobile subscript, u represents low voltage version (low voltage refers to sacrificing some performance on the same basis, lower voltage), MQ represents the quad-core Mobile, h on behalf of High-frequency version (is welded dead on the motherboard), HQ representative of the four-core high-frequency version, K for the overclocking version, x represents the strongest version

Generally we use M, HQ's on the line.

Graphics

Display interface card, as an important part of the computer mainframe, assume the output display graphics task. Simply put, the quality of your screen is determined by your graphics. The following is the latest graphics card performance Ladder chart, you can choose your own graphics card according to the performance comparison.

Common sense: The video card with M refers to the notebook dedicated, but not with M is the desktop use. (For example: gtx970m, GTX970)

Dual graphics card: The use of two graphics cards (integrated-independent, independent-independent) through bridge bridging, collaborative processing of image data work. The video cards produced by Nvidia and AMD are called SLI and cross Fire respectively. To achieve dual graphics cards must have motherboard support. This mode of operation can theoretically improve the image processing ability twice times, but the power consumption and cost are also very high. (Core graphics + Independent graphics) (Motherboard integrated graphics + standalone graphics)

End

Memory

The memory bar is the computer part that the CPU can address through the bus and read and write. In simple terms, the CPU must use the memory bar, so that all the contents of the external storage to play a role. The current mainstream laptops, at least have to use more than 2G of memory. Therefore, if the memory line capacity is not enough, will seriously affect the CPU processing speed, resulting in a computer screen, such as cotton phenomenon.

Configuration

According to the current notebook computer situation, if it is for students who just went to college, to use a 4 years, I recommend: I5 4210m + 4G + gtx840m/755m/850m/+ 500G/1TB price in: 3800-5000 (As for screen, Cooling effect these people consider themselves as appropriate, preferably the perfect screen + no radiator type.

Recommended several brands: Shenzhou God of war (pay attention to the screen, heat dissipation problem), Lenovo (anything is good is a bit expensive), mechanic (also line), McDull (also line), Hyun long (attention to heat problems) and so on.

I explain what is not a radiator, that is, when you use the computer to play the game, the computer will speed up, and some computer cooling system is better, you can keep the computer temperature stable in a safe value. And some of the computer's cooling system is poor, you need an external radiator, to strengthen the heat dissipation, otherwise, when the temperature reaches a critical value, out of self-protection, the computer will automatically shutdown.

If the pursuit of high-quality buyers: I recommend: I7 4710m/4720m + 8G + gtx860/870 + 1TB price in: 4800-7000 or so. This configuration has conquered the vast majority of games and software available on the market.

As for the addition of SSD solid-state drives, you can consider their own discretion. (Solid state Drive, I personally feel, the biggest function is to upgrade the boot speed, the fastest can reach about 10 seconds.) )

Recommended several brands: Thor (Everything is a bit expensive), Shenzhou God of war (pay attention to the screen, heat dissipation problem), Hyun-lung (attention to heat problems), Lenovo, Asus and so on.

"Where to buy"

"Taobao" no doubt, buy on Taobao, you can buy the lowest price to the desired products, of course, this needs to bear certain risks, and this certain risk depends on your eye.

If you buy Taobao, be sure to pay attention to the comments, see where he has any defects (such as cooling, screen, etc.) and the credibility of the store.

"Jingdong East" things generally will not be false, but the price is higher than Taobao hundreds of, if not on Taobao to buy things, it is best to come here.

"Entity shop" if not online shopping, strongly recommend to the entity shop to buy, after all, seeing for real, you can experience the computer performance, and return, maintenance is more convenient. (especially Lenovo, Asus these brands)

Attention matters

Online shopping to be cautious, everything is far below the market price of goods, there is a scam, do not be greedy to eat a big loss.

The above is how to buy a good notebook computer method introduction, hope to be helpful to everyone!
