Pay attention to the amount of cores and threads, and the values of special render-focused benchmarks, such as Corona Benchmark and CineBench. If you think your visualizations take too long, consider upgrading your CPU. So what about Corona Renderer – CPU or GPU? Corona Renderer uses only the processor (CPU) to render images. For example, V-Ray for 3ds MAX versions 4 and higher offers rendering through either a GPU or a CPU meanwhile, Cycles for Blender has a rendering mode that uses both at the same time. Each rendering engine is created to use only one of those, though some offer an option to choose which device to use. Such calculations can be done by either a GPU or a CPU. In essence, during image rendering, the computer is calculating what color to give to each pixel. However, in the realistic rendering sphere, everything is not as unequivocal. And yes, many real-time render engines (mostly used in video games) do use graphics cards for that. Then they face a question – what exactly should they buy to boost the rendering speed: a processor or a graphics card?Īt first, it may seem that creating images should be a job for a GPU. Sooner or later, every Corona Renderer user who has to wait hours for their rendering to finish starts thinking about upgrading their PC.
