I have two laptops with AMD APU+GPU combination, one is A6-5200M(8450G)+8570M, the other is A10-5757M(8650G)+8750M. Operating system is Windows 7 Professional(x64) with latest Catalyst driver(14.4) and latest DirectX runtime installed.
I'm currently learning C++ AMP programming and I want to use the delicated GPU for better GPGPU performance. Unfortunately the C++ AMP runtime only recognizes APU integrated graphics. Then I run GPU-Z 0.78 and find out 'DirectCompute' checkbox on 8570M and 8750M are unchecked(a C++ AMP-enabled device must support DirectCompute).
Question: Do 8500M/8700M series GPUs support DirectCompute? If they do support, how can I enable it?
