How memory speed is defined

Video memory speed is the memory clock pulse of the repetition cycle speed, is as a measure of video memory rate of the important indicators. The faster the memory speed, the larger the amount of data exchanged in units of time, in the same case the performance of the graphics card will be significantly improved.

The function of video memory speed

Video memory speed is the memory clock pulse repetition cycle speed, the faster the memory, the unit time exchange of data volume will be larger, in the same situation, the performance of the graphics card will be significantly improved.

The calculation of the clock cycle

The memory clock cycle is typically in NS (nanoseconds) and the operating frequency is measured in MHz. The memory clock cycle corresponds to the working frequency one by one, the relationship between them is: working frequency =1÷ clock cycle x1000.

With the same memory clock cycle, the equivalent output frequency of DDR SDRAM memory is twice times of that of SDRAM memory.

The method of video memory speed distinguish good or bad

The smaller the memory clock cycle is, the better. Video memory frequency and Memory clock cycle (that is, commonly referred to as XXNS) between the reciprocal relationship, that is, the smaller the memory clock cycle, it's memory frequency, the higher the performance of the graphics card is better!
