    OpenCL on CPU


      when we run an openCL program on the CPU, do the kernels run parallelly? 

      If yes, then what is the special advantage of using the GPU?

        • OpenCL on CPU

          with most powerful intel core i7 965 you can get around 70 GFLOPS and 50GB/s L1 cache speed. to ram it is 13GB/s

          Radeon 5870 have 2720 GLOPS and 150GB/s from VRAM.

          so with suitable task you can get significant speed up on GPU.
