So I installed APP SDK 2.8 for Windows. But it report version of SDK 1016.4 which is version that I can found in Linux catalyst 12.10. But Linux APP SDK report 1113.2. But more importantly on Linux 2.8 brings increase in maximum 2D image size from 8192 to 16386. On Windows it still report 8192. So it leave me with question if I Windows APP SDK installer contain proper version of OpenCL runtime.
