Graphics cards can be divided into several levels, how to look good or bad, how to look at performan

Generally speaking, it depends on the GPU, that is, the display chip, the quality of the GPU determines the grade of the graphics card, of course, there are other aspects, such as the size of the video memory, the type of video memory, which can directly affect the display quality of the graphics card.

For example, generally speaking, in NVIDIA's graphics card series, in the same grade of graphics cards, the performance of the Ti series is better than that of the MX series, for example, the performance of GeForce 4 Ti is better than that of GeForce 4 MX, and the performance of the same GeForce 4Ti series is 64M better than that of 32M, and the performance of DDR video memory is improved compared to SDRAM video memory, and so on.

As for the graphics card of the ATI series, generally speaking, depending on the GPU model, the larger the number, the better the performance, for example, 9700 is better than the graphics card.

In addition, the interface of the graphics card can also affect the performance of the graphics card, for example, AGP8X has a larger bandwidth and higher data throughput than AGP4X, which can give full play to the performance of the graphics card.

A little humble opinion.

I don't understand, but when I bought a graphics card, I had to look at the power supply.

Graphics card classification: 1. Integrated graphics card:

One refers to the motherboard chipset integrated display chip, the motherboard using this chipset can realize the display function without the need for a separate display, meet the general home audio-visual entertainment and office applications, and save the cost of purchasing a separate display.

2. Discrete graphics card:

A discrete graphics card, referred to as a discrete graphics card, refers to a graphics card that exists as an independent board and needs to be plugged into the corresponding interface of the motherboard.

3. Core graphics card:

The core graphics card is the epitome of a small host and is not highly integrated like a CPU, but has a lot of pre-made components on the motherboard.

1. How to distinguish the performance of the graphics card name:

1. Example of NVIDIA graphics card name: GTX560Ti

GTX is the graphics card version, and the performance is sorted by GTX>GTS>GT>G.

2. AMD (ATI) graphics card example: HD6870

HD is the graphics card version, and now there is no difference between the A card, and it starts with HD. The m at the end also represents the mobile version.

3. Compared with A card, the core code of N card is easy to identify, the core letters of the same series are the same, as long as you compare the size of the number to know the advantages and disadvantages of the core. The last digit is as small as possible, for example, the maximum number of stream processors for GK104 is larger than the maximum number of stream processors for GK106. The number of SPs can be directly compared with the same series, and the larger the graphics card, the better.

There are three types of graphics cards: independent graphics, core graphics, and integrated graphics.

The set display has completely disappeared, and now there are only independent displays and nuclear displays.

The most fundamental way to look good or bad is to look at the model, not the video memory that JS flickered.

For example, the GTX750TI of the N card, the independent display of 900 yuan, and the standard 2G video memory. The performance is much stronger than that of the GT730 2G.

It is completely wrong to look at the size of the video memory capacity.

First, look at the core architecture of the graphics card (N card is stronger than A card to play games), second, look at the number of stream processing of the graphics card (A card is a group of 5, N card can be processed and operated individually), and third, look at the core frequency, the higher the better.

Fourth, look at the bit width (bit) of the graphics card, all those below 128bit are ignored, and now the mainstream ones are 256bit

Fifth, look at the size of the video memory, the current video memory is basically 1G.

However, the graphics card still depends on the brand and **.

In the first-line brand, A card buys sapphire, and N card buys zotac.

**Of course, the more expensive the graphics card is more than 1,000 yuan, the better.

The best graphics card right now is AMD's HD6990, five thousand nine; The N card is GTX590, six thousand nine.

High-end graphics cards, there are no less than 2000, they are all money-throwing guys, >

Core. Number of stream processors. The memory bit width. Core frequency. Video memory rate. The size of the video memory. The above influence has gradually diminished

In many ways! Core, Frequency, Bit Width, Bandwidth, Capacitor Layout, Heat Sink, and more! **The higher the higher, the higher the high-end High-end = high heat + high energy consumption.

Upstairs is right, the main thing is the price, the more expensive the better.

1. Look at the prefix, most of the current market are GT and GTX, GT is the prefix of low-end graphics cards, the more classic GT740, GT730K, etc., the new mobile graphics card (notebook) GT920M and so on. The GTX is a mid-to-high-end graphics card, the more classic ones are GTX970, GTX980, GTX980TI, and the newer ones are GTX1060, GTX1070, etc.

2. Look at the first digit, for example, the GT740 mentioned in the first point, 7 means the seventh generation, the 9 in the GTX980 is the 9th generation, and the 1060 is the 10th generation, the larger the number, the newer.

3. Look at the second digit, which is a more important point, because the second digit of the performance of the graphics card is very decisive. For example, GTX970 and GTX980, 8 is larger than 7, so the performance of the 980 is higher than that of the 970, and the higher the second digit, the better. The older graphics card GTX460 and GTX750, although 6 is bigger than 5, but there are three generations between them, so GTX750 is better than GTX460.

But another example is the GTX780 and GTX950, the GTX780 is two or three times the performance of the GTX950, although they are separated by two generations. So the second digit is important.

So the N card is the prefix GTX, the bigger the first digit, the better, the latest is the 10 series graphics card, the bigger the second digit, the better, such as GTX1080. The most important thing is the second digit, the landlord can go to the graphics card ladder diagram.

AMD: I don't know much about AMD's graphics cards, but to briefly mention that AMD has HD series, RX series and R series graphics cards. HD used to be the mainstream of Internet café families, but due to high power consumption, it was gradually eliminated, and the current market is mainly R series and RX series graphics cards.

The recognition of AMD graphics cards is basically the same as that of N cards, such as R7 350, R9 370, the bigger the number after R, the better, in 350, the larger the second digit, the better, but AMD launched RX460 RX470 RX480 after that, of which RX480 is almost the same as GTX1060 performance, and the high-end A card is R9 390X, RX480, R9 Fury R9 Nano, etc., the specific performance is still recommended to go to the graphics card ladder diagram, sorry, The A-card is not particularly well understood.
