    OpenCL features per video card

    greenman

      Is there more detailed info of OpenCL features supported per video card?

      http://developer.amd.com/sdks/AMDAPPSDK/pages/DriverCompatibility.aspx

       

      For example, my HD 6870 does not support "cl_khr_fp64".

      When querying with clGetDeviceInfo and CL_DEVICE_EXTENSIONS, neither cl_khr_fp64 nor cl_amd_fp64, are listed.

      It would be useful to know if FP_CONTRACT is supported as well.

       

      I would consider upgrading to a newer video card if it has full cl_khr_fp64 support.

       

      cheers,
