    RAM
    RAM in video cards (also known as video memory or VRAM) is a special type of memory used by a video card to store graphics data. It serves as a temporary buffer for textures, shaders, geometry, and other graphics resources that are needed to display images on the screen. More RAM allows the graphics card to work with more data and handle more complex graphic scenes with high resolution and detail. Show more

    TMUs
    Responsible for texturing objects in 3D graphics. TMU provides textures to the surfaces of objects, which gives them a realistic look and detail. The number of TMUs in a video card determines its ability to process textures. The more TMUs, the more textures can be processed at the same time, which contributes to better texturing of objects and increases the realism of graphics. Show more

    ROPs
    Responsible for the final processing of pixels and their display on the screen. ROPs perform various operations on pixels, such as blending colors, applying transparency, and writing to the framebuffer. The number of ROPs in a video card affects its ability to process and display graphics. The more ROPs, the more pixels and image fragments can be processed and displayed on the screen at the same time. A higher number of ROPs generally results in faster and more efficient graphics rendering and better performance in games and graphics applications. Show more
