videómemóriától

Videómemória, often referred to as VRAM, is a specialized type of random-access memory (RAM) used in computers and gaming consoles to store image data that a graphics processing unit (GPU) needs to display on a monitor. It acts as a high-speed buffer, allowing the GPU to quickly access and process the textures, frame buffers, and other graphical assets required for rendering. The amount and speed of video memory directly impact the performance and quality of graphics, particularly in demanding applications like video games, 3D rendering, and video editing.

Higher resolution displays and more complex graphical elements require larger amounts of VRAM. Insufficient video memory can lead to performance bottlenecks, where the GPU has to constantly fetch data from slower system RAM, resulting in stuttering, frame drops, and reduced visual fidelity. Modern GPUs typically come with dedicated VRAM chips, such as GDDR5, GDDR6, or HBM, offering significantly higher bandwidth and lower latency compared to standard DDR RAM used for system memory. The specific type and capacity of VRAM are crucial factors when choosing a graphics card for gaming or professional graphics work.
