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)?

There are both CPU and GPU renderers for offline rendering. GPUs have massive scalability and so more and more people are using them because they can just throw in another gpu and increase their render speed whereas with a CPU you might have to change your entire system. Games are heavily optimised and rul alot better on GPU due to the amount of precomputation that is usually done to optimise loading times and things like that.
