What can 512 graphics card do compared to 1G What are the shortcomings Seek a professional explanati

Video memory is only used to store frame cache data, and different games have different requirements for video memory under different settings.

Some games that eat video memory, such as GTA4 and Crysis, are better to need 1G under high effect, otherwise the video memory may explode.

Under normal circumstances, 1680*1050 and below resolution, 512M is sufficient, 1920*1080, 1G video memory is recommended.

There is no absolute relationship between video memory and performance. Just like the memory of a computer, running out of memory will cause problems, but memory has little to do with the performance of the CPU.

So look at the graphics card, or look at the display core first. The core and the combination of the core and the video memory are the most important.

The same 1G graphics card, there are 600 or even lower more than 400, and there are also 2000-3000 enthusiast level.

The low-end 4,500 graphics card with 1G of video memory is like the old Celeron with 2G memory, no matter how much you increase the capacity, it is a waste of money.

I hope that the whites will change the bad habit of looking at the graphics card and only looking at the video memory, so that JS can cry.

1G is slightly better than 512M video memory, in the case of the same frame, 1G is slightly better! That is to say, if you use 512 in 800*600 mode, playing games is equivalent to using 1024*768 mode in the case of 1g. To put it bluntly, it is a large video memory, which can be played to make the game play more smoothly at higher resolutions.

The most basic function of the graphics card is to display the screen, 512MB and 1GB refer to the video memory of the graphics card, because the most common use of the graphics card is to play 3D games, 3D maps and 3D materials will be used when playing 3D games, theoretically the larger the capacity of video memory, 3D games will have more space when computing 3D textures and materials, In other words, a 512MB video memory will be smoother when playing 3D games than 256MB video memory, especially for heavy 3D games. It requires a lot more memory to handle a lot of 3D textures and materials.

But if you don't play 3D games, there is basically no difference between 512MB and 1GB of video memory, which means that the amount of video memory will only show the difference when you play 3D games.

In fact, it's not that 512 is necessarily worse than 1G The first data of the reference graphics card is not the video memory but the bit width It is a large score of a highway Even if it is repaired in a gorgeous road width is not enough to still jam the traffic You will find that some of the same brand 256bit512m graphics card is much more expensive than 128bit1g 128bit512m half of the 3D games are no problem But those effects are very gorgeous It's a little hard But 256bit512m is very easy to deal with this kind of game Recommended Shadow Race Sapphire Dilan Hengjin.

Large video memory can only play its performance on a large screen and high resolution, if your screen is not 24 inches or more. There's no need to use 1g

The feeling of 512 is not very good now, the ratio is 500 and 1000, which is bigger, which performance is better.

Update 1:Generally speaking, the AMD Atlanton Phenom 4-core series can exhaust the filial piety performance of the above graphics card, right?

The HD5770 chip is an intermediate chip.

The resolution and the RAM of the graphics card do not have a big impact, and in addition, the general game 200 MB is not used.

If the same is buried if it exceeds 512MB, the graphics card will'Borrow'host ramFinally, the missing GDDR5 RAM is fast, so the 512MB is convex. AMD Athlon, Phenom supports PCI, but Intel Ivy Brige supports PCI E 2x faster.

Reference: me

AnswerQ2 The graphics card should be matched with the motherboard, the 1G graphics card is common, and the PCI slot of the motherboard graphics card should have PCI Ex16. Motherboards that have been released in the past two or three years are fine.
