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)?

Blender does use GPU to speed up its Cycles rendering engine. Larger scenes may cap out the Vram on the GPU so you may have to use CPU for rendering.
