How can you tell a graphics card from its appearance?

1. Look at the PCB, the more layers, the better, which can reduce the influence between parts.

2. Look at the capacitance, of course, the solid-state capacitor is the best.

3. Look at whether the soldering place of the component is not smooth, whether there is a gap and the smoothness of the edge of the circuit board.

4. Look at the fan, the enclosed turbine type heat dissipation is the best.

5. Look at the manufacturer, how the reputation is.

6. There is no damage to the interface.

7. The brand and quantity of video memory.

Black is the best on the board, and the core frequency is more important than the memory frequency.

If you look super cool, it must not be cheap (such as the kind with an oversized radiator).

On the surface, it is generally based on workmanship and materials.

The graphics cards of first-tier manufacturers are generally unambiguous, and the layout of cables and devices is very integrated.

It is also very textured in the hand.

Manufacturers of lines are often in order to save costs.

Therefore, the materials used will be reduced, and the wiring will be worse than that of larger factories.

The above is for your reference.

If you look at it more, you can see the difference.

Two graphics cards of the same model. Don't look at the heat dissipation capacitors, the better. The higher the memory frequency, the better.

I really can't choose it, I suggest you buy big factories and German goods, forget it, don't care about the workmanship. Just use it.

First of all, the weight is heavy, but don't buy the passive heat dissipation of the heat sink will make you regret it...

The second is to look at the brand... Look at the capacitance of the solid state and the particles.

As long as you buy a mainstream model of graphics card from a major manufacturer, you won't be fooled.

Don't buy the same German OEM on the line, Onda, rainbow, etc., the garbage is dead, the appearance is almost the same, the color is different, haha.

Graphics card is the core hardware that determines the performance of a computer game, the importance can be imagined, now there are many graphics card brands and models on the market, how to distinguish the good from the bad when choosing a graphics card? In the graphics card parameters, you can generally see several important parameters such as the graphics chip, video memory capacity, graphics card bit width, core frequency, and video memory frequency, which are the core parameters that determine the performance of the graphics card. Therefore, we can judge whether the graphics card is good or bad by these parameters.

1. Display chip.

The graphics chip is the core chip of the graphics card, which is mainly used to process the first-class information input from the system and build and render it, which directly determines the performance of the graphics card. The current graphics card chip brands are mainly NVIDIA and AMD.

Second, the core frequency.

The core frequency of the graphics card refers to the working frequency of the display core, and its working frequency can reflect the performance of the display core hole to a certain extent, but the performance of the graphics card is determined by the core frequency, video memory, pixel pipeline, pixel fill rate, etc., so in the case of different display cores, high core frequency does not mean that the graphics card has strong performance.

3. Memory bit width.

Similar to highways, the wider the road, the faster the vehicles and speeds that can pass, so the width of the memory is also an important factor in determining the performance of the graphics card. At present, the bit width of the graphics card generally reaches 128bit, and some better graphics cards reach 256bit, or even 512bit.

4. Video memory capacity.

Video memory capacity is the amount of local video memory on the graphics card, which determines the ability of the video memory to store data temporarily, so it will also affect the performance of the graphics card to a certain extent. Currently, most of the video memory capacities are 2GB, 3GB, and 4GB.

Note: A larger memory capacity does not necessarily mean that the graphics card will perform higher, because the three factors that determine the performance of a graphics card are the graphics chip first, the memory bandwidth (which depends on the memory bit width and memory frequency), and finally the memory capacity.

Generally speaking, it is reasonable to match the performance of the graphics core, and the higher the performance of the display chip, the higher the processing power, the higher the memory capacity should be correspondingly larger.

5. Video memory frequency.

The memory frequency refers to the frequency at which the graphics card is working on the graphics card by default, measured in MHz (megahertz). To a certain extent, the frequency of the video memory reflects the speed of the video memory. The memory frequency is related to the memory clock cycle, and the two are reciprocal, that is, the memory frequency = 1 memory clock cycle.

6. Video memory type.

The mainstream graphics card memory type is GDR5, some old graphics cards or entry-level graphics cards, the performance of the GDR3 video memory type is relatively poor, try to choose the mainstream graphics card type.

Summary: First look at the display chip brand and core frequency; Then look at the memory bandwidth, generally the larger the better; After that, check the memory capacity, and it is reasonable to match the performance needs of the graphics core. Continue to check the frequency and type of video memory, etc., it is recommended to choose GDR5 mainstream graphics card.
