GPU (Graphics Processing Unit)

Geforce2 mx400 GPU

GPU is the processor used in a computer graphics hardware to process large and complex 3d graphics or applications. It is a single chip with integrated transform, lighting, triangle setup/clipping and rendering engines. Creating lighting effects and transforming 3d models are computationally intensive tasks which effects the performance of computer system. These all tasks are offloaded  from CPU onto the GPU for better performance of computer and so all scenes increase in detail. Transform engine creates a motion effects in 3d models by converting its frame of reference point into another frame continuously millions of times each second. Lighting engine generates lighting effects on 3d models.
