What is the video memory frequency

Memory frequency refers to the frequency, in MHz (megahertz), that the display is working on the video card by default. Video memory frequency to a certain extent reflects the speed of the video memory. Video memory frequency with the type of video memory, the performance of different, SDRAM video memory generally work in a lower frequency, is generally 133MHz and 166MHz, this frequency has long been unable to meet the needs of the current graphics card.

Overview of video Memory frequency:

Memory frequency refers to the frequency, in MHz (megahertz), that the display is working on the video card by default. Video memory frequency to a certain extent reflects the speed of the video memory. Memory frequency varies with the type and performance of video memory.

Calculation of Memory Frequency:

Memory frequency and Memory clock cycle is related to the reciprocal relationship between the two, that is, video memory frequency =1/Memory clock cycle. This is for SDRAM memory, if the memory of the DDR, the calculation is the actual operating frequency, but also multiplied by an integer to be able to achieve, for example, the DDR to multiply by 2,DDR2 to multiply 4,DDR3 to multiply by 8.

How to distinguish the level of video memory frequency:

In the same type of video memory, as long as the direct comparison of the actual operating frequency or equivalent frequency on the line, generally speaking, the higher the better. If they are of different types, in general, the newer the better.
