Intel CPU only OpenCL benchmark.

I used John and ImageMagick to do the benchmark with the Intel OCL sdk installed.

The results (John) --

With ImageMagick convolve filter --
With OpenCL --

As we can see, the Intel SDK is of no good. Maybe they could've spend more time on developing their hardware and drivers instead of making shiny GUI on .NET.
