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
