Such a small, low-detail image will not provide a case for using GPU rather than CPU, but once you start upping the image size and detail, a modern GPU will provide endless benefit over a modern CPU. + +For example, using the CPU-based fractal-gen, a 10240x10240 pixel image at +1000 iteration cutout per pixel, the image will complete in just under 4 +minutes when running on all 32 threads of a dual-Xeon E5-2670 setup.
