Most operations on the GPU operate in a vectorized fashion: one operation can be performed on up to four values at once. For example, if one color R1, G1, B1 is to be modulated by another color R2, G2, B2 , the GPU can produce the resulting color R1*R2, G1*G2, B1*B2 in one operation. This functionality is useful in graphics because almost every ...
Prime also features a CPU fallback when no compatible GPU is found on the system. Unlike OptiX, Prime is not a programmable API, so lacks support for custom, non-triangle primitives and shading. Being non-programmable, OptiX Prime does not encapsulate the entire algorithm of which ray tracing is a part.
Components of a GPU. A graphics processing unit (GPU) is a specialized electronic circuit initially designed for digital image processing and to accelerate computer graphics, being present either as a discrete video card or embedded on motherboards, mobile phones, personal computers, workstations, and game consoles.
These APIs have also proved vital to computer graphics hardware manufacturers, as they provide a way for programmers to access the hardware in an abstract way, while still taking advantage of the special hardware of any specific graphics card. The first 3D graphics framework was probably Core, published by the ACM in 1977.

OCLToys, [126] [127] collection of OpenCL examples; opencl-stream, [128] OpenCL implementation of the STREAM [129] benchmark; SNU NPB, [130] benchmark; mixbench, [131] benchmark tool for evaluating GPUs on mixed operational intensity kernels
Lists of graphics cards follow. A graphics card, or graphics processing unit, is a specialized electronic circuit that rapidly manipulates and alters memory to build images in a frame buffer for output to a display.
The Videocore GPU runs an RTOS which handles the processing; video acceleration is done with RTOS firmware coded for its proprietary GPU, and the firmware was not open-sourced on that date. [92] Since there was neither a toolchain targeting the proprietary GPU nor a documented instruction set , no advantage could be taken if the firmware source ...
