Why are games rendered with a GPU while Blender, Cinebench and other programs use the CPU to render high quality 3d imagery? Why do some start rendering in the center and go outwards (e.g. Cinebench, Blender) and others first make a crappy image and then refine it (vRay Benchmark)?

When images are rendered using the CPU that’s called a software renderer as opposed to a hardware renderer of a GPU, for the most part, GPUs can render images more efficiently than CPUs can, the reason that those benchmarks use software renderers are because a software renderer is very taxing on the CPU and those programs are benchmarks/stress tests.
