2G graphics card becomes 1G, what does 2G graphics card on computer mean?

Let me tell you, I accidentally deleted the system recovery disk and my system crashed. I had to go to customer service to reinstall the system, but when I came back, the hardware master detected that the GT-555 N card of 2G became a 1G integrated display, and I was confused for a long time and even suspected that my graphics card was replaced after sale. But the running score is normal, and the game response is normal.

Finally, I reinstalled the driver of the graphics card, and the result showed normal. The conclusion is that the installed driver is not exactly suitable for your graphics card, but it can be used improvised, and the 1G HD5600 driver is installed in your computer, so the hardware detection defaults to your graphics card is the 1G version. My computer is the ASUS N55 graphics card I just bought, and it is a GT-555 2G

He didn't lie to you, some graphics cards have 2G sharing. In reality, the graphics card itself only has 1G, and the other 1G of video memory is shared from memory. Also, shared video memory only has a certain effect on the game, and is not useful for other general software.

Another point,The second floor is right,Video memory is only a one-sided reaction to the quality of the graphics card,Many graphics cards with low video memory are much better than graphics cards with high video memory,Even a grade,The graphics card still depends on the comprehensive performance。

Video memory is only a one-sided reflection of the quality of your graphics card, which also has the main frequency and bit width of the graphics card, 5700 is originally 1G video memory, 128 bit wide, but it will become 2G or higher when the memory is shared.

What's so good about 2G, GTX580 is just video memory.

This means that the memory size of the computer graphics card is 2GB. Video memory is also called frame buffer, which is used to store the rendering data that has been processed or will be extracted by the graphics card chip. Like a computer's memory, video memory is the part that is used to store the graphic information to be processed.

Video memory is the component used to store the graphic information to be processed. The picture seen on the display is composed of pixels, and each pixel is used to control its brightness and color with 4 to 32 or even 64 bits of data, which must be saved through the video memory, and then handed over to the display chip and CPU for deployment, and finally the calculation result is converted into a graphic output to the display.

The main difference between the two is in the capacity of the video memory particles, from a macro point of view, the size of the video memory, 2G video memory can render twice the graphics data of 1G video memory at the same time.

As for the data: for example, the GTX 770 1G and GTX 770 2G graphics cards run the same game at 1920x1080 resolution, and all other things being equal, the 2G version runs at about twice the frame rate of the 1G version, but in most cases, there is basically no difference in the frame rate between the two when not running on a high-resolution monitor.

Video card, graphics card, also known as graphics card, is one of the most basic configuration and most important accessories of a computer.

When choosing a graphics card, you can't just look at the video memory.

It doesn't make much sense.

Look at his frequency.

Bit width process. And so on and so forth! 1G graphics cards and 2G graphics cards are literally just a matter of memory size! It's up to you how you choose!

Just like CPU and memory, it's just that the GPU and video memory of the graphics card are specially used to process graphics data, and a larger video memory will of course improve the processing performance to a certain extent, but it also depends on the corresponding bit width. If the bit width is not enough, no amount of video memory will be useful. In other words, the current 2G sounds quite bluffing, but some of them are furnishings that can't be used at all.

The video memory of the graphics card.

size, which basically has no impact on the performance of the graphics card. Large video memory is only suitable for large monitors and high image quality.

There is a difference in the size of the video memory of the graphics card.

The difference between a 1G graphics card and a 2G graphics card is the video memory, and the size of the video memory capacity determines the ability of the video memory to temporarily store data, and it will also affect the performance of the graphics card to a certain extent.

If it is the same model of graphics card, the advantage of large video memory is reflected in the high resolution and the consumption of video memory when there are many units in large scenes.

Generally speaking, the memory capacity should match the performance of the graphics core, the higher the performance of the display chip, the higher its processing power, the higher the memory capacity should be correspondingly larger, and the low-performance display chip equipped with large capacity video memory is not helpful to its performance.

Mid-to-high-end graphics cards 1G video memory is more common, enough to deal with large games, 2G video memory is mostly seen in flagship-level graphics cards, or professional graphics workstation-level graphics cards, as far as playing games is concerned, 1G and 2G are not at all different.

2G video memory?? It's really rare. For example, the video memory is like a pool that determines how much water it can hold, and the video memory width is like a water pipeline, which determines how much it can output.

It depends.

In the low-end graphics card, there is actually almost no difference between 1G video memory and 2G video memory, because the performance of low-end graphics cards is often not high, and its performance limits the use of large-capacity video memory. That is to say, in the low-end graphics card, even if it is installed with 2G video memory capacity, it is a waste, they can't give full play to the full power of 2G video memory, and some entry-level independent graphics cards even have 1G video memory is a waste.

However, the current situation does not mean that it will be the same in the future. When the performance of low-end graphics cards can catch up with the performance of current high-end graphics cards in the future, then 2G video memory can really become popular.

In the mid-range or even high-end graphics card, 2G video memory can really play its role, especially some games with high requirements for video memory capacity, this role is more obvious, such as GTA 4 This game, it has extremely high requirements for the capacity of video memory, 1G video memory can't feed it, 2G video memory is the best choice.

In addition, the larger the size of the display, the higher the capacity requirements for video memory. It is said that 27 inches is a threshold, more than 27 inches of computer monitors, 1G video memory is not enough, there must be more than the capacity of video memory to display normally. However, this statement has not been confirmed by the person himself, because even 25-inch monitors are far from popular now, let alone 27-inch ones.

The most important criterion for measuring a graphics card is not the video memory, which usually makes little difference.

For the same model and brand, the difference in actual life applications can be ignored, except for the high display degree, the difference can be seen.

It's hard to say! The performance of the graphics card mainly depends on the following aspects:1Brand 2Chip 3Video memory (including size and speed of video memory)4The craftsmanship of the graphics card.

Video memory is not the main thing, but also look at the video memory bit width. 128b bit width is good.

It's just a little bit, the performance is high, and it doesn't matter if the video memory is less.

The 1G and 2G versions refer to the memory size of the graphics card. One of the video memory graphics cards, which is equivalent to the memory as the CPU, is used as a data cache, and the data is lost when the power is off.

Theoretically, all other things being equal, the larger the video memory, the better the performance of the graphics card. But there are exceptions to everything, when the video memory is large to a certain extent, even if the video memory is increased, but because the core performance of the graphics card is very poor or the core performance of the graphics card has been exerted to the limit, then increasing the video memory cannot increase the performance of the graphics card.

In the market, I often see some low-end graphics cards with large video memory, such as GT610, this kind of card, I often see a 2G version, in fact, it is completely unnecessary, the main reason for the poor performance of GT610 graphics card is the poor performance of the graphics card core, even if this core gives him 20G video memory, it is just a bright card, and it can't be played.

When buying a graphics card, look at the core first, and then look at other parameters, such as: video memory, bit width, stream processor, video memory frequency, etc.

1G is real, 2G is virtual. For example, if you play a game using 1G, when you play two games, 1G will be less. But virtual 2G can show the role of 1G in the second game.

Video memory is mainly used to store image data displayed on the screen. If you have a small screen resolution, 1G of video memory will suffice.

In the case of the same core chip, 2G video memory can be turned on for larger resolutions and more games, generally 2G video memory is used on 23-inch monitors, if your monitor is 19 inches, 1G is enough, and the size of video memory has nothing to do with performance for mass applications. The performance of the graphics card still depends on the chip model, and generally the people who talk about the graphics memory are people who don't understand or are fooling you.

If the model is the same, DDR5, the bit width and bit are the same, the video memory capacity of 1G and 2G is larger. In fact, the important thing about the graphics card is the bit width, as long as the bit is wide, it doesn't matter if the capacity is smaller, generally speaking, 1G is enough, there is no need to buy 2G to spend more money, 2G capacity. The 128-bit wide graphics card does not yet have a 1G capacity. A 256-bit wide graphics card is good.

Video memory is used to store the data processed by the graphics card, which acts as a cache. The so-called screen is not big, the video memory is a waste, to be precise, the screen resolution is not large, if you often play games at high resolution, then the required video memory will be very large, but you also have to consider the processing power of the GPU, the graphics card is not good enough, the GPU can not handle more data, so the video memory required will be relatively small. Generally speaking, choosing a graphics card within 1,000 yuan, 2G video memory is indeed a waste, and high-end graphics cards need more video memory, otherwise there will be performance bottlenecks.

Of course, it's the difference in capacity. It's like your memory stick. The bigger the better!

This is an unimportant technical parameter for a merchant to deceive people who don't understand computers.

The most important thing is the chip model, and the secondary thing is to look at the memory capacity.

To give you the most rubbish entry-level graphics card like GTS 610 now, give a 100G video memory, but it can't match the performance of the GTX980 512MB graphics card 1 10.

2G is the video memory The larger the video memory, the better the performance of the graphics card The graphics card mainly depends on the chip bit width, processing stream, and power consumption.

This means that the video memory size of this discrete graphics card is 2G.

A discrete graphics card is a graphics card that exists in the form of a discrete board and can be freely plugged and unplugged on a motherboard with a graphics card interface. Discrete graphics cards have separate video memory that does not occupy system memory, and are technologically ahead of integrated graphics cards to provide better graphics and performance.

Video memory is the component used to store the graphic information to be processed. The picture we see on the display is made up of pixels, and each pixel controls its brightness and color with 4 to 32 or even 64 bits of data, which must be saved through video memory, then handed over to the display chip and CPU for configuration, and finally the calculation result is converted into a graphic output to the display.

Video memory, like motherboard memory, performs the function of storage, but it stores information about each pixel that the graphics card outputs to the display. Video memory is a very important part of the graphics card, after the graphics chip processes the data, it will save the data to the video memory, and then the RAMDAC (digital-to-analog converter) will read the data from the video memory and convert the digital signal to an analog signal, and finally it will be displayed on the screen.

2G graphics card refers to the video memory of the graphics card is 2G, merchants generally rely on this to fool people, video memory has little impact on the performance of the graphics card, unless a large display can see some differences, the performance of the graphics card mainly depends on the core architecture, video memory bit width, etc.

It's all about discrete graphics cards Discrete 2G is talking about discrete graphics cards with 2G video memory, and profiteers like to deceive people with video memory, the least important attribute of the graphics card.

Indicates the cache of the graphics card, the larger the better.

This kind of word is generally a special word that ignores people, the performance of the computer is not about G, generally this word represents the video memory of the graphics card is 2GB size, for measuring the performance of the graphics card, just looking at this parameter is obviously not enough, now many low-end graphics cards have made the video memory into 4G, 8G, the performance of the graphics card generally depends on the model of the graphics card, for example, GTX970, as long as you see this model, you can judge the performance of the graphics card, because GTX970 video memory is generally 4G, ** is 2500 yuan, Some GT610 also have a 4G version, **generally not more than 500, compare** to know who is superior and who is inferior.
