Solution: The most notable difference between CPU and GPU rendering is that CPU rendering is more accurate, but GPU is faster. 3ds Max offers several built-in render engines which take advantage of both CPU (Central Processing Unit) and GPU (Graphics Processing Unit) rendering.
Is rendering CPU or GPU intensive?
Though it might take hours (maybe even days) to finish rendering an image, traditional CPU-based rendering is more likely to deliver higher image quality and much clearer images that are devoid of noise. A GPU has many more cores than a CPU, but overall, each core runs slower compared to a CPU core.
Does game rendering use CPU or GPU?
Most of today's games ask a lot from the GPU, maybe even more than the CPU. Processing 2D and 3D graphics, rendering polygons, mapping textures, and more require powerful, fast GPUs. The faster your graphics/video card (GPU) can process information, the more frames you will get every second.
