How to calculate the frequency of the graphics card and what are the problems of the frequency of th

It seems that this frequency is not calculated, as for 4x and 8x are the specifications of the agp graphics card interface.

AGP Specification: AGP 1x AGP 2x AGP 4x AGP 8x working voltage.

Clock frequency: 66mhz, 66mhz, 66mhz, 66mhz, working frequency: 66mhz, 133mhz, 266mhz, 533mhz, theoretical bandwidth: 266mb s, 533mb s, 1066mb s, 2100mb s

Bandwidth bits: 32bit, 32bit, 32bit, 32bit

4x 8x has nothing to do with frequency, that's the agp interface bandwidth (the bigger the better).

Now PCI-E graphics cards are all 16x.

The frequency of the graphics card mainly consists of the core frequency and the memory frequency (geforce8 and hd 2x00 also have a renderer frequency), which are determined by the graphics card itself, and there is no calculation problem.

CPU refers to the ** processor, the core processing unit of the graphics card is called GPU, and its core frequency is the clock frequency of the GPU.

The 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. At present, there are three kinds of memory widths on the market: 64-bit, 128-bit and 256-bit, and people are accustomed to calling 64-bit graphics cards, 128-bit graphics cards and 256-bit graphics cards to refer to their corresponding memory bit widths. The higher the memory bit width, the better the performance**, so the 256-bit wide video memory is more used in high-end graphics cards, while mainstream graphics cards basically use 128-bit video memory.

The active clock is the frequency at which your video memory is actually utilized. Let's say your graphics card is using DDR memory because DDR does 2 tasks in one clock. So the true frequency*2 is his effective clock frequency.

The core frequency of the graphics card refers to the working frequency of the display core, and its working frequency can reflect the performance of the display core to a certain extent, but the performance of the graphics card is determined by the core frequency, video memory, pixel pipeline, pixel fill rate, etc., so in the case of different display cores, high core frequency does not mean that the graphics card has strong performance. For example, the core frequency of 9600Pro has reached 400MHz, which is higher than the 380MHz of 9800Pro, but in terms of performance, 9800Pro is definitely stronger than 9600Pro.

In the same level of chips, the higher the core frequency is more powerful, and increasing the core frequency is one of the ways to overclock the graphics card. There are only two mainstream display chips, ATI and NVIDIA, both of which provide graphics cores to third-party manufacturers, under the same graphics core, some manufacturers will appropriately increase the frequency of the display core of their products, so that it works at a frequency higher than the fixed frequency of the display core to achieve higher performance.

The difference between the graphics card of the same core, GT GS and other models, the difference is the frequency, so the higher the frequency, the higher the **, but the manufacturers are often conservative when producing products, and those who can run 700 are often set to 600, in order to be stable, the refresh frequency is to release this part of the reserved frequency, just like the overclocking in the CPU is the same, spend the same money to enjoy higher speeds.

You can use PC Manager's hardware detection to view the information.

1. First, click on the toolbox to open the hardware detection tool.

2. Click on the graphics card information to view the frequency of the graphics card.
