- Definition: Frame Buffer
-
The separate and private local memory for a GPU on a graphics AIB. The term frame buffer is a bit out of date since the GPU’s local memory holds much more than just a frame or an image for display as it did when originally developed. Today the GPU’s local memory holds programs (known as shaders) and various textures, as well as partial results from various calculations, and two to three sets of images for the display as well as depth information known as a Z-Buffer.
