Please recommend me a block graphics card!The quality and efficacy must be good!It s best not to hav

Sapphire HD 4870x2 **3999

Absolutely.

Let's go to the computer city to have a look, generally speaking, of course, the more expensive the money, the better the performance.

I'm not a professional who is too detailed.,Just say something simple and practical.,It's also my own experience:

1. The performance of a graphics card does not depend on the size of the memory capacity (this is the main misunderstanding of most novices), the most critical thing for the graphics card depends on the core process, bit width, stream processor and memory particle type and other parameters, such as DDR5 and DDR3, DDR5 is 2 times faster than DD3, and under the same brand type, the DDR 5 performance of 512M is stronger than that of 1G DDR3. If it is the same DDR5, then there is no difference in performance between the 512M and 1G graphics cards;Bit width is very important, but it is not said that the higher the bit width, the stronger the performance, the current game needs more than 128 bit width, for example, GTX660 graphics card, its bit width is 192, but its memory frequency is high, making up for the lack of bit width, I believe its performance you know;The more streamers the merrier, of course.

My personal experience in choosing a graphics card is: the second digit of the N card must be above 5 to be considered a good graphics card, and the second digit of the A card must be above 7 to be considered a good graphics card. The following are all low-end entry-level graphics cards.

2. At present, the main brands of N-card first-line graphics cards are ASUS, Gigabyte, ZOTAC, MSI, HIS, Yingzhong, etc., and the first-line brands of A-card mainly include MSI, Sapphire, Dilan, Xunjing (originally made N card, but now it has been converted to A-card) and so on. The second line mainly includes: Yingla, Rainbow, Weconex, etc.

When you say that the same price is almost the same parameter, it mainly depends on the brand, and the first-line workmanship is of course better than the second-line workmanship.

I kind of understand what you mean,Actually, you said what graphics card you should choose?,To be honest,The performance of the above graphics cards is almost the same,The first one should be a sapphire brand,Because HD7750 power consumption is small,Overclocking ability is stronger,More development potential,So strictly speaking, 7750 will be better。 But in fact, the three graphics cards can only be regarded as mid-range graphics cards, slightly stronger than HD6770, it is recommended that you do not have to choose among the three, it is recommended that you go to HD6850 is the first choice, more cost-effective, stronger performance, slightly stronger than HD7770. MSI or Sapphire is recommended, about 900 yuan.

Or I have a look at the latest graphics card performance ladder chart for you to see, or it may be helpful to you:

1.It is difficult to distinguish the workmanship of graphics cards from professionals, especially if they belong to the same level of manufacturers. Usually only from outside the graphics card.

2.The cost performance is only available when comparing, which requires you to have a full understanding of the performance of various graphics cards.

3.Graphics card performance in general, mainly depends on the GPU model. The more intuitive the number, the better the performance (same manufacturer).

In terms of details, it depends on the number of GPU stream processors, the frequency of GPU cores, followed by the memory bandwidth (determined by the memory bit width and memory frequency), and finally the memory size.

4.A graphics card with the same price and parameters depends on which brand you like, and which graphics card is pleasing to the eye, that's it.

Personally, I think that Gigabyte, Asus, MSI, and Litai belong to the first-tier brands. Rainbow, Mingxuan, Xiangsheng, Yingtong, Shuangmin, Leifeng and so on belong to the second-tier brands. And Sapphire, Xunjing, Zotac, Yingla, and Dilan Hengjin are in between. That's what a lot of people say. Hehe.

1 Anyway, ASUS and Gigabyte are all big manufacturers.

2 bits wide first, video memory second.

3. The good ones are all D5 video memory with high frequency.

4. Most of the games are N cards, because N cards have physical acceleration, A cards, no 5, and workmanship and after-sales Generally, 2-3 years for large factories, large factories generally have solid workmanship, and sufficient materials are used, please adopt.

In general, the way to judge the performance of a graphics card from the parameters is as follows:

First of all, compare the graphics chip's graphics chip (usually the later it is launched, the more sophisticated the manufacturing process, the higher the performance) and the type of video memory;

Second, compare the bandwidth and memory speed of the graphics card. The higher the bandwidth and the faster the memory speed, the better the performance of the graphics card, and the higher the performance**.

Memory (core) bandwidth = memory (core) operating frequency * memory (core) bit width 8

Memory frequency (MHz) = 1000 memory speed (ns) * factor.

Therefore, when comparing, it is necessary to consider the frequency of the graphics card (including core frequency and memory frequency), bit width (core bit width and memory bit width), and the speed of video memory.

PS: The idea that "the more memory you have, the better the performance of your graphics card" is wrong.

For example, under the same conditions, the performance of a graphics card with 128MB of video memory and 256bit width is better than that of a graphics card with 256MB of video memory and 128bit width.

In addition, parameters such as the pixel render pipeline, pixel render units, and the number of vertex shading engines are also important factors in determining the performance of the graphics card.

It should be noted that the above identification methods are only suitable for general situations, and some special situations such as manufacturers optimize the board design and power supply design, or use better workmanship materials, so that the comprehensive performance of the graphics card exceeds its original level. At this time, the above methods cannot be rigidly applied. It is necessary to analyze the situation on a case-by-case basis.

First-tier manufacturers Taiwan's Asus, Gigabyte, MSI, ZOTAC, and EVGA in the United States, among which ASUS ranks first in terms of popularity and brand.

Dilan Hengjin is also good, and the poison series, the workmanship performance is good in the A card.

The workmanship of the graphics card is generally the card backplane and the power supply after removing the radiator.

However, generally well-made graphics cards** are more expensive.

Remember the stacking of these first-line ASUS, ZOTAC, and EVGA in the United States. Among them, ZOTAC is known as the king of stockpiles.

Performance options I won't talk about the old graphics card, just the new naming method.

N-card GT is low-end, GTS is mid-range, GTX is high-end, GTX+digital+TI is a strengthened version, GTX+ digital+SE is a reduced version.

gtx is an example.

There are three numbers after it.

For example, GTX560, GTX 670, GTX690

The first number "5" is the algebra of the generations of the graphics card, and the second digit is the status of the graphics card in this graphics card.

Note: The second digit of the N card is less than 5, and the number is ranked in the ranks of low-end gadgets.

The latest graphics cards are the GTX6** series, GTX650 GTX660 GTX660TI GTX670 GTX680 GTX690

Recently, the N card has released the graphics card information of the GTX7** series, and there is currently a Titan graphics card, and the performance of this graphics card is between GTX680 and GTX690.

There is also the fact that the performance of the GTX560 is about the same as that of the GTX650.

So while the 650 is 100 bigger than the 560, the performance gap is only determined by the second digit.

Now let's talk about the A-card.

The HD***A card is a 4-digit number.

The last of them doesn't count.

The first is algebra and the same goes for n-cards.

The second place is the place in the generation of graphics cards.

The third place is the rank in this position, and the bigger the better.

All hands hit, class dead.

1. Look at the memory bit width, that is, 128bit, 256bit or something, the bigger the better. Two graphics cards with different bit widths are not of the same level;

Second, look at the production process, that is, 45nm, the smaller the better;

3. Look at the core frequency and memory frequency, the bigger the better;

Fourth, it is to look at the brand, if you have N card, Zotac and Yingchi are good, and if you have a card, Sapphire and Dilan Hengjin are good.

A little deeper are the stream processors, which will be indescribable for a while.

You don't have to learn it deliberately, you will be familiar with it if you look at the evaluation more, give you a martial arts cheats, the left is the N card, the right is the A card, the higher the performance, the same level on the left and right represents the same performance, the cost performance of a graphics card depends on how much the same kind of A card or N card of this performance sells, and then the previous layer, the next layer of the graphics card than see how much more expensive it is, how much cheaper, you can estimate whether it is worth the price.

Talking a bunch of nonsense, can you see the workmanship?

It depends on whether you buy an ATI card or an NVIDIA card, and now that ATI has been acquired by AMD, if your CPU is AMD, try to choose an ATI graphics card.

ATI graphics card brands tell you several Sapphire, Dilan Hengjin, Xunjing NVIDIA graphics cards, Yingla, Gengsheng, and Rainbow.

The criteria for distinguishing graphics cards tell you a few things.

1.Display chip (gtx***gts***hd***2.)Memory type (DDR3, GDDR3, GDDR5)3Bit width

4.Video memory capacity (1G, 2G, 3G).

Complements now there are also dual-core graphics cards to consider if you are not short of money.

There is no good or bad, only suitable, and this problem is the same as how to choose a good car

Look at the performance of the graphics card and then look at the ** performance mainly depends on the video memory.

1. Open the case, 2. Install a Master Lu, etc.
