Anonymous users2024-02-07The bit width of the video memory is the number of bits of data that can be transmitted by the memory in a clock cycle, and the larger the number of bits, the greater the amount of data that can be transmitted in an instant, which is one of the important parameters of the video memory.
Memory bandwidth Memory frequency x memory bit width 8
The memory frequency refers to the frequency at which the graphics card is working on the graphics card by default, measured in MHz (megahertz).
Core bit width refers to whether the CPU is 32-bit or 64-bit, which seems to have nothing to do with the graphics card.
The core frequency of the graphics card refers to the operating frequency of the display core.
The memory frequency refers to the frequency at which the graphics card is working on the graphics card by default, measured in MHz (megahertz).

Anonymous users2024-02-06The graphics card core and video memory are two different parts, just like the CPU and memory of the computer, if it can be the same, the CPU will not be designed with L2 cache, and the same is true for the graphics card.

For example, the CPU and memory on the motherboard.

Anonymous users2024-02-04Yes, the memory bit width, the larger the memory bit width, the stronger the performance.
The main reason is: video memory bandwidth (GB s) = actual frequency of video memory (MHz) x video memory data magnification * video memory equivalent bit width (bit) 8, then in the case of the same memory frequency, the memory bit width will determine the size of the video memory bandwidth.
For 128-bit and 256-bit memory with the same memory frequency of 500MHz, the memory bandwidth is: 128-bit = 500MHz*128 8 equals 8Gib s, while 256-bit = 500MHz*256 8=16Gib S, the memory bandwidth of the 256-bit graphics card is twice the memory bandwidth of the 128-bit graphics card.
In the same model, it is natural that the larger the video memory, the better. If it is a different model of graphics card, it should be considered comprehensively, and you can't just look at the aspect of video memory. It's like the GTX 1050Ti has 4G VRAM, but the performance is not as good as the GTX 1060 3G VRAM version.

Anonymous users2024-02-03This is a different version launched by manufacturers according to different market needs, such as GTX750, under normal circumstances, 1G of video memory is enough, but playing large 3D games requires 2G of video memory. Video memory is only one of the factors in judging the performance of a graphics card, and you also need to refer to other filial piety factors when buying a graphics card: video memory bit width:
The bit width of the video memory refers to the number of bits of data that can be transmitted in a cycle, and the larger the number of bits, the greater the amount of data transmitted in a short period of time, so the video memory is one of the important parameters of the graphics card. There are 64 bits, 128 bits, 256 bits, and 512 bits of memory width. The higher the memory bit width, the better the performance of the graphics card.
Frequency: Frequency is the speed at which the graphics card processes data, is the speed at which data is exchanged with the GPU, the unit is ns or MHz, 1ns=1000 1MHz, the faster the frequency of the video memory, the more channels there are, the larger the amount of data that can be processed at the same time, and the better the performance of the graphics card. Memory bandwidth:
Memory bandwidth is one of the indicators to measure the data transmission rate between the display chip and the video memory, generally speaking, the higher the bandwidth, the faster the data transmission speed, the unit is byte seconds. With the same frequency, the performance of the graphics card with higher bandwidth will also be better. Stream Processor:
The stream processor is the pixel rendering pipeline and vertex shading unit, also called the SP unit, the role is to process the data split chain transmitted by the CPU, and convert it into a digital signal that can be recognized by the display after processing, of course, the higher the stream processor, the better. Comments.
In fact, the parameters of the current graphics card are not as much as the previous graphics card, and there are very few shrinking graphics cards, and the indicators are already relatively balanced. >>>More
The graphics core is the most important. Responsible for handling all the calculations of the game. The second is the stream processor, each stream processor is like a group, the more groups there are, the higher the corresponding processing efficiency, and the auxiliary GPU is rendered together. >>>More
All important. For example, the GPU (graphics card core, more important than the video memory) needs to process 50GB of data per second, and the amount of data shipped to the GPU by 256 bits of video memory is 256 8=32B each time, so in order to meet the needs of the GPU 50GB of data per second, the number of times the video memory needs to deliver data to the GPU in 1 second 50GB 32B = 50*1024 32=1600M s, that is, the 256-bit video memory needs to deliver 1600 million data to the GPU per second to meet the GPU The demand for data, the number of times the video memory is shipped per second is actually the frequency of the video memory, and the frequency of the video memory is determined by the type of video memory GDDR5 has the highest frequency, so now high-end card video memory is equipped with GDDR5, the purpose is not to follow the trend, but to achieve a higher frequency. >>>More
The capacity has nothing to do with the other three, it only determines how many material library files can be held in the video memory. >>>More
Because Yan Hui really understood the knowledge and ideas that Confucius had acquired throughout his life, and he had great similarities with Confucius in terms of thought, although the other apprentices had their own achievements, their thoughts were not necessarily the same as Confucius.
