How to distinguish the advantages and disadvantages of graphics cards, and how many types of graphic

128m 258m This is all about the size of the graphics card.

7800 refers to the graphics card model.

The important parameters of the graphics card are:

Core, bit width, most people think that video memory is very important, just like the hard disk is very large, there is no improvement in performance, that is actually not very important!

There are only two production cores in the world, NVIDIA and ATI. Called N card and A card.

Their naming convention is that the higher the number, the stronger the performance.

For example: NV: Gefore 8600GT, 9600GTATI: HD3850, HD4850

Performance is enhanced in turn!

The one you said is the first two 128m, and 256m is the size of the video memory, but there should be no 7800 model!

Brand and model The 128m and 256m you said should be cache, generally speaking, the higher the cache, the better, except for some exceptions, 7800 should be the number of hard disk revolutions.

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 file 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 a separate 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 the number is compared, the car is small to know the core advantages and disadvantages. 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.

If you say it well, do you mean the performance is high or low, or whether it is damaged? In terms of performance, just refer to the 2019 graphics card ladder chart.

It mainly depends on the larger the video memory and transfer speed, the better.

1 Graphics core: The higher, the better.

2 Graphics card core frequency: the bigger, the better.

3 graphics card memory capacity: the bigger the better Generally more than 500 yuan 512MB4 video memory type: generally GDDR3 Good GDDR45 video memory frequency: the higher the better, the lower 1600MHz and the higher 2200MHz or more.

6. Video memory speed: the smaller, the better, not greater than 1ns

7 video memory bit width: the bigger the better Most of them are 256bit8 interface type: now it is generally PCI Express X16 configuration like the landlord, and it is more appropriate to use an ATI graphics card.

Recommended **A card at 590.

See if the lines are arranged in an orderly manner. It's like doing housework. Is it not folded piece by piece.

Very well planned. Looking at capacitors again, the good capacitors now use Fujitsu's blue capacitors. Tantalum capacitors.

The simple point is to see if the capacitor has feet. Those with feet are electrolytic capacitors, and those without feet are chip capacitors. SMD capacitors can only be installed by large manufacturers.

Cottages are all made with cheap capacitors with feet. It's intuitive. The other way is to test the score of the graphics card with software such as Mark 2011.

The higher the score, the better. But in the store, you generally don't have to test it. Those installed in front of you can fool you.

So let's look at it intuitively. In the end, the easiest thing is that the heavier the graphics card, the better. This is called solid material.

Video memory and GPU... The size of the video memory determines the speed at which data can be accessed (similar to the work of memory), and the size of the GPU determines the speed at which data can be processed (similar to the work of the CPU). Compare the memory and GPU of the two graphics cards to know whether the performance is good or bad.
