    Is the OpenCL support generic? As in, can it be used with Intel's Beignet or with POCL as well?

      Not sure about beignet, but I didn't see it being used when using clover(opencl for radeon).

        It is generic but due bugs in beignet/pocl (or incomplete implementations) it does not work. It was only tested against AMD and NVidia OpenCL.

          Hmm what version of opencl do they require? Blender wiki says:
          OpenCL OpenCL is supported for GPU rendering with AMD graphics cards. We only support graphics cards with GCN architecture (HD 7xxx and above). Not all HD 7xxx cards are GCN cards though, you can check if your card is here.
          Cycles requires recent AMD drivers to be installed, on all operating systems.

            The baseline for the GCN I believe is OpenCL 1.2.

              If OpenCl is supposed to work with Nvidia aswell, why don't I get an OpenCL option? GTX 670.

                You need to install cuda/opencl packages.

                  Try this:
                  CYCLES_OPENCL_SPLIT_KERNEL_TEST=1 blender

                  It might work... but then again opencl is done for gcn arch so you might better of with cuda.

                  There is updated opencl page for blender cycles:
