For example, the core frequency of 9600PRO has reached 400MHz, which is higher than the 380MHz of 9800PRO, but 9800PRO is definitely stronger than 9600PRO in terms of performance. In the same level of chips, the higher the core frequency, the higher the performance, and the overclocking of the graphics card is one of the ways to increase the core frequency. There are only two mainstream display chips, ATI and NVIDIA, both of which provide display cores to third-party manufacturers. Under the same display core, some manufacturers will appropriately increase the display core frequency of their products to make them work higher than the display core. Fixed frequency to achieve higher performance.
Video memory frequency
The video memory frequency refers to the frequency at which the video card is working on the graphics card by default, in MHz (megahertz). The video memory frequency reflects the speed of the video memory to a certain extent. The video memory frequency varies with the type and performance of the video memory. SDRAM video memory generally works at a lower frequency, usually 133MHz and 166MHz. This frequency has long been unable to meet the needs of current graphics cards. DDR SDRAM video memory can provide a higher video memory frequency, which is basically no longer used. Since the appearance of DDR5 video memory far exceeds DDR2 video memory and DDR3 video memory in terms of cost performance, DDR2 video memory and DDR3 video memory are gradually withdrawn from the market. DDR5 video memory is currently the most widely used video memory type for low, medium and high-end graphics cards. The video memory frequency that different video memory can provide is also very different, mainly 3100MHz, 3200MHz, 3400MHz, 3800MHz and so on.
