There are pros and cons of onboard graphics??? Will the onboard graphics card eat the memory and h

As the saying goes, "Han Xin points soldiers, the more the merrier", with the rapid development of games and hardware technology, as well as the decline of video memory particles, the memory capacity of mainstream graphics cards is also rising, the first two years for mainstream graphics cards or standard configurations64MB video memory has been unable to meet the needs of practical applications, the use of 128MB video memory graphics cards are now quite common, and 256MB or larger capacity of video memory will be the main trend of future popularization. With the rise of large-capacity GDDR2 and GDDR3 video memory, the "256MB popularization style" has become a hot topic in the market and a focus of consumer debate. Is there a need for a large amount of video memory, and do we need a large amount of video memory like 256MB?

This article will explain this.

About the memory capacity.

Video memory, which means display cache, is mainly used to temporarily store the data processed by the display chip, including the data that has been processed and will be processed, so the channel between the display chip and the video memory is very important, and whether it is smooth or not is directly related to the performance of the graphics card.

When we talk about video memory, we often talk about 64MB, 128MB, 256MB and so on, which all refer to the capacity of video memory. Here is a simple calculation formula for you, video memory capacity, horizontal resolution, vertical resolution, number of color bits, 8bits. When using 2D applications, such as in the display mode of 1024 768 32, then the required video memory capacity 1024 768 32bit 8bit 3145728 byte=, this is only a 2D application, if it is a 3D application, then the required video memory capacity 1024 768 32bit 3 8bit 9437184byte , of course, these are the minimum requirements for application, There must also be a certain amount of video memory capacity to store texture data or z-buffer data, otherwise when the video memory capacity is completely occupied by the display resources, the system will automatically call the memory to be used as the texture video memory, and the memory cannot be compared with the video memory in terms of speed, so the second call will naturally lead to a decrease in display performance.

First of all, the onboard video memory must be relatively unintegrated, and the existing integrated graphics card is stronger, but the integrated graphics card is integrated after all, but it is not as good as the low-end independent graphics card, and if you want to "play well" the game, you still have to install a graphics card, but if the budget is not enough now, then go first780g After all, you can upgrade the graphics card The economic point of buying Onda and Colorful is on the line, they are all channel providers, basically made by the same factory, pasting different brands, after all, with 128m existing.

Why do people always complicate the answer to the question, who can understand it, it is recommended to choose the motherboard of Onda But it is better to choose a discrete graphics card,

Problem description: Will the onboard graphics card "eat" the memory and hard disk?? Does an onboard graphics card really reduce memory? Why??

For example, if 256 is to be "eaten" by more than 50, the result will be saved about 200?? Why?? Also "eat" hard drives to reach 5G??

Why?? Then why don't you have to be "eaten" memory and hard disk when you buy a discrete graphics card???

Analysis: The onboard graphics card has no video memory, take a part of the memory as the video memory, the memory has to run other software so it has to be occupied, what to do when the memory is not enough, then Min Hu Mo uses the hard disk to do the cache, and keeps reading back and forth, so the memory is small and the reason for playing games and other cards is that Li Naji, the onboard graphics card will "eat" the memory and the hard disk to eat, depending on how big the game you play or the program you run, the onboard graphics card has no video memory, so there is a little bit of memory to occupy, When you don't play games and run programs, he also takes up memory, and the display desktop also needs a certain amount of space.

The independent graphics card has its own video memory, such as 32m, 64m, 128m to play general games can be dealt with, the capacity can also be enough, large games are not easy to say, as for which game occupies how much memory, I think no one has tested, his video memory is not enough to occupy the memory which socks memory is not enough to occupy the hard disk, so the independent graphics card is much faster.

Running general programs, office, surfing the Internet, etc., does not use much video memory (memory), which is the most expensive to play games.

I don't know if you understand, if it's good for you, give me 30 points.

1.When you enable onboard video memory sharing system memory, you do not need to manually adjust the frequency of video memory and system memory.

2.If the onboard video memory is DDR3 and the system memory is DDR2, it is difficult to determine whether the video memory should be used at a reduced frequency, and no relevant information can be found;

3.If the onboard video memory is DDR2 and the system memory is DDR3, the system memory can also be shared as video memory.

The onboard graphics card is a graphics display chip integrated on the motherboard in terms of hardware, which is different from the traditional one, which needs to be plugged into the AGP or PCIe slot on the motherboard.

In terms of working principle, it is to divide an area from the memory as an integrated graphics card, and the traditional graphics card has integrated video memory.

In terms of performance, it is definitely the traditional graphics card that is more popular.

However, computer technology has been updated, and the performance of some integrated graphics cards has surpassed that of mid-range discrete graphics cards, such as the relatively new i-series processors, which have integrated graphics display functions, and the performance is better with the corresponding motherboards, which is no less than some discrete graphics cards.

In the past, integrated graphics cards shared video memory from memory, that is, a part of the memory was separated from the memory as graphics card storage.

Nowadays, some motherboards have onboard video memory, that is, the video memory of the integrated graphics card has been added when the motherboard is manufactured, and there is no need to share it from memory.

There is a slight increase in the frame rate of the game. You can't play a game that you can't play, and it's not particularly meaningful. When you buy a motherboard, you don't have to worry too much about whether you have onboard video memory, it's just a selling point.

But then again, something is always better than something not. **, if the brand is excellent, of course, choose the onboard video memory.
