This is very wrong task for GPU. Great speed of GPU is not a result of fast cores, but number of cores + ability for running huge amount processes in parallel. It need dozens of thousands of parallel processes just to supply enough work for its cores (maybe even hundreds of thousands in new GPUs). Anything less than that mean that it not fully used. And to reach its full performance you will need images of few mega pixels.
