In computer graphics, a video card's pixel fillrate refers to the number of pixels that can be rendered on the screen and written to video memory in one second. [1] Pixel fillrates are given in megapixels per second or in gigapixels per second (in the case of newer cards), and are obtained by multiplying the number of render output units (ROPs) by the clock frequency of the graphics processing ...
If a computer has two video cards that combine their outputs into a single video monitor, then one of four methods could be used to create the images. Alternate Frame Rendering (AFR): One graphics processing unit (GPU) computes all the odd video frames, the other renders the even frames. (i.e. time division)
In computer graphics, double buffering is a technique for drawing graphics that shows less stutter, tearing, and other artifacts.. It is difficult for a program to draw a display so that pixels do not change more than once.
In computer graphics, the render output unit (ROP) or raster operations pipeline is a hardware component in modern graphics processing units (GPUs) and one of the final steps in the rendering process of modern graphics cards.
Common graphics drawing commands (many of them geometric) are sent to the graphics accelerator in their raw form. The accelerator then rasterizes the results of the command to the framebuffer. This method frees the CPU to do other work. Early accelerators focused on improving the performance of 2D GUI systems. While retaining these 2D ...
A graphics library or graphics API is a program library designed to aid in rendering computer graphics to a monitor. This typically involves providing optimized versions of functions that handle common rendering tasks.

A stencil buffer is an extra data buffer, in addition to the color buffer and Z-buffer, found on modern graphics hardware. The buffer is per pixel and works on integer values, usually with a depth of one byte per pixel. The Z-buffer and stencil buffer often share the same area in the RAM of the graphics hardware.
