As of today, the latest Intel OpenCL drivers supports very few different image formats (only 32 formats for latest 184.108.40.20632 GPU driver and 43 formats for latest "beta" CPU driver). These are very few compared to the 80-100 formats supported by Nvidia and AMD. The lack of "full" image format support leads to undesirable introduction of Intel-specific work-arounds that both complexifies code and reduces performance. In particular, it had been a great advantage if "SNORM"-types could been supported for CL_R/CL_RG/CL_RGBA x INT8/INT16.
