Graphics card 128MB, 256MB What does 215Mb mean

It is recommended to encyclopedia.

Bandwidth. The memory bit width is the number of bits of data that can be transmitted in a clock cycle, and the larger the number of bits, the greater the amount of data that can be transmitted at the same frequency. In 2010, there were mainly 128 bits, 192 bits, and 256 bits of graphics cards on the market.

And the memory bandwidth = memory frequency x memory bit width 8, which represents the data transfer speed of the video memory. In the case of comparable memory frequencies, the memory bit width will determine the size of the memory bandwidth. For example:

For 128-bit and 256-bit memory with the same memory frequency of 500MHz, their memory bandwidths are: 128-bit = 500MHz * 128 8 = 8GB s; And 256 bits = 500MHz * 256 8 = 16GB s, which is twice as many as 128 bits. The video memory of the graphics card is composed of video memory chips, and the total bit width of the video memory is also composed of the bit width of the video memory particles.

Memory bit width = memory particle bit width Number of memory particles. The memory particles are equipped with the memory number of the relevant manufacturer, you can go to the Internet to find its number, you can understand its bit width, and then multiply it by the number of memory particles to get the bit width of the graphics card. For other graphics cards with the same specifications, the larger the bit width, the better the performance.

Capacity. All other things being equal, the bigger the capacity, the better, but you can't just look at the video memory when comparing graphics cards (many JSs will sell low performance cores with large video memory). For example, the 384M 9600GT is much stronger than the 512M 9600GSO because of the gap between the core and memory bandwidth.

Video memory capacity is only one of the considerations when choosing a graphics card, and factors such as cores and bandwidth are more important, which determine that the performance of the graphics card takes precedence over the video memory capacity. However, the necessary amount of video memory is a must, because in the case of high resolution and high anti-aliasing, there may be a shortage of video memory. Currently, the memory capacity of graphics cards on the market ranges from 256MB to 4GB.

Video Memory: The larger the video memory, the smoother the game.

128MB represents video memory.

It 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.

Like a computer's memory, video memory is the part that is used to store the graphic information to be processed. The image we see on the display is made up of pixels.

Each pixel controls its brightness and color with 4 to 32 or even 64 bits of data, which must be saved through the video memory, then handed over to the display chip and CPU for configuration, and finally the result is converted into a graphic output to the display.

Yes, the video memory capacity is 256MB

The graphics card is a chipset in a BGA package on the motherboard, similar to the CPU (Central Processing Unit), which is called GPU (Graphics Processing Unit) in the industry, and there are two main manufacturers in the market: NVIDIA and AMD.

The graphics chip is equivalent to the CPU of the graphics card, but its main task is to process the display information, in the process of processing the information, it will produce a large amount of temporary data (unprocessed, processed, has been processed), which requires a special place to store these temporary data, that is, the video memory, it may also be a chip, or it may only be a part of the chip, which depends on the design of the hardware (discrete graphics card and integrated graphics card).

Graphics card 256M means that the Shadow Calling Graphics Card has 256M of video memory.

The computer only occupies the main memory as texture memory, and such a second call will cause the display performance to deteriorate, so the video memory capacity as a real 3D acceleration card must be greater than.

The video memory of the workstation graphics card is more than 64MB. For example, in the case of 2D drawing applications, even in the case of 1600x1200, the maximum is 1600x1200x32bit 8bit=7680000byte=, if it is 3D drawing such as 3D Studio Max, then the capacity requirement is macro, but this is the minimum requirement.

Therefore, the 32MB capacity of video memory is suitable for this kind of 2D drawing or entertainment ****, ordinary 3D design. For workstations, because of the larger software and larger computing, the video memory is more than 256M.
