GPU rendering is the computation of images from 2D or 3D scene descriptions using the massively parallel processing units of a graphics processing unit rather than the CPU. By executing shading, rasterisation, and ray-tracing workloads across thousands of cores, it delivers real-time interactive graphics and accelerates offline rendering. It is foundational to game engines, visualisation, and digital-content creation tools.

- Real-time GPU rendering rasterises geometry and runs programmable shaders per frame, while modern hardware adds dedicated ray-tracing and tensor cores for global illumination and AI denoising. Offline GPU renderers trade interactivity for physical accuracy, accelerating path tracing far beyond CPU-only pipelines. Throughput depends on memory bandwidth, VRAM capacity, and effective parallelism, making scene optimisation and level-of-detail management important.
