The core clock of your GPU is the performance of your GPU’s main chip, also known as the processor of the GPU (don’t confuse it with the main processor of the computer). Memory clock (VRAM) can be overclocked Core Clock Explained.Higher and faster VRAM can offer better performance as compared to lower and slower VRAM (memory clock).It temporarily stores parts of the graphics (textures, effects, etc).Memory clock Is the RAM of your GPU also known as VRAM.Similarly, a GPU with LARGER VRAM can store more data and free up some load of the GPU.
A GPU with a FASTER VRAM can store data more quickly and increase the overall performance of the GPU. Now, the question arises “does VRAM or memory clock affect performance?” However, the difference is VRAM stores various textures, effects, objects, and elements of the graphics of the game you’re playing or the program you’re using. And quite similar to the computer RAM, the RAM of the GPU (VRAM) is also used to store data temporarily. In other words, the memory clock is the frequency of the RAM of your GPU. Memory clock refers to the VRAM (don’t mix it with the DRAM which are the sticks that we put on the motherboard) of your GPU.
