What does game resolution have to do with graphics card? How much video memory is needed for a large

According to the normal way of 3D games, the data is cached from the hard disk to the memory in advance by the CPU control, and then the required part is called to output to the graphics card, the graphics card caches the data in the memory first, and then the GPU starts to calculate the part that needs to be displayed and output.

At the same time, the higher the resolution setting, the pre-cached data will also increase, and the capacity will also be limited, when the bandwidth or capacity of the video memory is insufficient, the GPU will not be able to obtain timely data calculation output, and the frame rate of the picture will be very low.

Maximum resolution and required video memory space.

Normal 2D screen: 8 bits of video memory (horizontal resolution, vertical resolution, number of color bits) required for each frame

Normal 3D screen: 8 bits of video memory required for each frame (horizontal resolution, vertical resolution, number of color bits, 3).

The higher the resolution, the clearer the picture, of course, the greater the requirements for the performance of the graphics card, and the greater the requirements for the existing one. Now graphics cards, 2G video memory abounds.

As mentioned upstairs, the resolution at which the game runs depends on the performance of the monitor, graphics card, memory and other hardware, not only the display parameters as a reference. The game needs to run at a high resolution, depending on whether the hardware supports it, otherwise the game will run very unsmoothly.

The amount of power consumption should depend on the load of the CPU and graphics card.

1. Play games.

The most important thing for high resolution and low resolution is that the graphics card is working, that is to say, if your graphics card is fully loaded at high resolution and 50% load at low resolution, then the power and power consumption should be 2 to 1; If the game you play is already fully loaded at low resolution, then it will not be increased at high resolution, and at this time you can only sacrifice the smoothness of the game, and the power consumption is about the same!

Second, if you are drawing, then you have to consider the CPU and graphics card together, generally the higher the resolution, the higher the requirements for the CPU, especially the rendering renderings, almost all CPUs are working at full load, the difference between good and bad CPUs is the rendering time, that is, your power consumption time!

In fact, the landlord doesn't have to think about it so much, playing cool is the last word, what is the electricity bill of dozens of dollars compared to your playing mood!

The 9800GT can be used to bring more than 400W of power supply, and my desktop at home is still 455W, and there is not so much electricity for using a laptop when surfing the Internet.

I just have a power meter on hand, and I also have a card, which is generally measured for standby and full load.

Most of the 9800GT does not have 2D crossover, so the power consumption is mostly 40 100W, the power consumption of the graphics card depends on the load of the graphics card, as for the game settings in addition to vertical synchronization, other settings generally do not affect the load of the graphics card, because the setting is high and the setting is low, the frame rate is also floating, so the load of the graphics card is not much different, in low resolution, it is necessary to turn on the vertical synchronization to limit the number of frames, in order to reduce the load of the graphics card, and at the same time, it can also effectively reduce the power consumption.

This is really no one has evaluated the graphics card standby and full load The higher the resolution, the higher the requirements for the graphics card If the graphics card has limited performance but wants to achieve high results, then there is only overclocking In the case of overclocking, the power consumption is still relatively strong.

1024*768=786432

Doubles power consumption.

The greater the allocation rate, the more processing is carried out. The more you process, the GPU will heat up.

It's not just about electricity.,The key is that the resolution is large.,Use the card.,The frame rate can't keep up.,Your 256-bit estimate is no problem.。。 If you consume power, if you have a 256-bit graphics card, it is best to use a power supply with a 400 rated power.

10%；Get a plug-in board with power display, test standby and full load to know.

The fee is a must, and I really don't know how much to calculate. There is a strongman please.

My home computer. 2G RAM. Dual-core graphics. Play with wow and asked. It means that the pear is not big.

According to the graphics card model given in the question stem, today, 5 years later, basically no games can be played.

In the case of comparable GPU performance, products with larger memory bit widths will have stronger resistance to high-resolution pressure, but the fundamental factor that determines the performance is the GPU model itself.

The so-called good horse with a good saddle, GPU is like a horse, and video memory, radiator, power supply unit and other parts are like a saddle, they are complementary to each other, forcibly give a horse (such as GT610 such as entry-level GPU) with a "good saddle" (2GB or even larger video memory, but limited by GPU performance limitations, the bit width is still only a shameful 64bit), although it looks vain, but it is meaningless.

Correspondingly, if it is a mid-to-high-end GPU, such as R9-280X, you can choose the 6GB version, which basically eliminates the common 3GB version sometimes bursting video memory, and the performance is more incisive.

3D games do eat graphics cards, and the evaluation of graphics cards is not simply the width of the video memory bit can explain the problem.

A good graphics card depends on the following parameters.

1. Graphics card architecture, generally speaking, the new architecture will have more advantages than the old architecture 2. Video memory, the bigger the better.

3. Generally speaking, the more stream processing units, the better.

4. The frequency of the graphics card, the higher the better.

5. The lower the temperature of the graphics card, the better.

For example, for example, N card GTX760, video memory 2G, bit width 256bit, GTX960, video memory 2G, bit width 128bit, if you just one-sided think that the bit width is good, the graphics card is better, this is wrong. Because the architecture, frequency, and stream processing unit of the 960 are better than the 760, its performance will be more than 10% higher than that of the 760.

Bit width is a bit more important. The following analogy can be made:

The process of rendering a 3D game screen in real time on a graphics card is compared to a car passing through a toll station, then the bit width is like how many toll gates there are at the toll station, and the video memory is like how many cars can be accommodated on the road. Then in the case of the same number of cars, the more toll gates, the faster the car passes, and the less likely it is to get stuck in traffic. So bit width is a bit more important.

64bit is a four-lane road.

128 six-lane.

256 eight-lane.

No matter how many cars there are, the road is only so wide, what's the use.

It's just as important, but the video memory is generally 512 is enough, and the bit width is as large as possible, preferably 256bit

Bit width is important, and a lot of video memory is expanded, and generally 512 video memory is 256bit bit width.

Video memory is the temporary processing power of the graphics card. When the graphics card is working, it has to transfer the processed data into the video memory first, and then process it. Of course, the larger the video memory, the more data it processes temporarily. The better the display performance.

For general 3D games, you should use a graphics card with a minimum of 64M video memory. It is recommended to use the 128m one to play like this, which will be a little cooler. Hehe..

As for what you said about not having enough video memory. Well, it seems that there is no other good way to change a graphics card with a large video memory.

Add a separate graphics card, not enough video memory, play Warcraft, it is recommended, 256m display size, 7300gt or more, you can pull.

It seems that LZ doesn't understand very well, the four configurations are actually not very good, and the fourth is only relative.

1. AMD Athlon's LE-1640 is single-core, and it has long been discontinued.

It's dual-core, but it's hard to find now, and the performance is not good, so it's not recommended.

3. AMD Athlon's X2 BE-2300 is dual-core, and its performance is worse than 4400+!

4. Both boards are very backward, and the current standard configuration is 790GX series motherboards, and I want to use the 785G series of integrated displays.

There is a 770 series with a separate display.

5. The best is the fourth set, and the most cost-effective is also the fourth set, but there is no graphics card.

It is difficult to play large-scale 3D online games without a graphics card, and 785G on the motherboard is still a bit of a trick.

The reason why the fourth set is relatively good is because this set is still a mainstream configuration, and things are still easy to find.

The fourth set can be changed in this way, and it is relatively more in line with your use case after the change.

U on 245 is better, only 5 yuan more expensive, motherboard for Spartak BA-210, memory on DDR3

This is more mainstream,Onboard HD4200Centralized display,Play games can also be handled,LZThe board you choose is AM2 interface,U of the AM3 interface on it,And the performance is not good,The key is,I can't find the goods at all。

The other sets are backward configurations, things from a few years ago, and it is impossible to play online games now.

Don't say that the big hard disk is useless,Now the size of stand-alone games and online games is not small,Install a few of your hard disks and go to more than half,Besides, 80G hard disks have long been extinct,Now a few are on more than 320g,Generally equipped with 500G hard disk。 What's more, if you want to sell 80g hard disks now, you can sell about 200, 320g is only 300, 500g is only 350, 640g380, which one do you choose?

lz, choose the mainstream configuration, electronic products are updated quickly, don't be nostalgic for the previous electronic waste.

According to the actual requirements of the game, the official ** of the current large-scale 3D online game will be marked with the standard configuration of the game. In addition, Shanda Games has special detection software. However, in my personal opinion, if you want to play the more popular online games, you can raise the video memory to 512 or 1G.

In this way, most of the online games on the market can be played.
