Videómemória

Videómemória, also known as video memory or VRAM, is a specialized type of random-access memory (RAM) used by the graphics processing unit (GPU) of a computer. Its primary function is to store image data that is currently being displayed on the screen. This includes textures, frame buffers, and other graphical assets that the GPU needs to access quickly to render images.

Unlike system RAM, which is used by the CPU for general computing tasks, VRAM is designed for high bandwidth and fast access by the GPU. This allows for smoother and more detailed graphics rendering, especially in demanding applications like video games and professional design software. The amount of VRAM a system has is a significant factor in its graphical performance. More VRAM generally means the GPU can handle higher resolutions, more complex textures, and more graphical effects without stuttering.

There are different types of VRAM, with newer generations offering increased speed and efficiency. The most common types include GDDR (Graphics Double Data Rate), which is widely used in consumer graphics cards, and HBM (High Bandwidth Memory), which is found in high-end professional GPUs and offers even greater performance. The architecture and speed of VRAM directly impact how quickly a GPU can process and display visual information.
