(not parent) Yes, since highend GPUs have 1,000's of cores, it makes sense (though I wouldn't expect one GPU core to be faster than one CPU core.)

Please, could you quote the CPU and GPU for which you got that 350x speedup? Also, for the 1000x speedup.

(also, it would be interesting to know the CPU/GPU that gave the original 1 hour to 0.2 sec (18,000x speedup) - I'm guessing other factors like network latency, low-end CPU + high-end CPU, optimized code etc were part of it.)
