title: cl_khr_gl_sharing is supported for Pentium G860 but not for Core i7-4960X
body: <p>I have two computers, one with a GTX 980 + Intel Core i7 4960X and the other one has a AMD Radeon HD 7850 + Pentium G860. I am getting device features with opencl's <code>clGetDeviceInfo</code> function. I am wondering why the Penitum G860 is supporting <code>cl_khr_gl_sharing</code> extension and Core i7-4960X is not supporting in OpenCL.</p>
  
  <p>Is that something related to difference between AMD and nVIDIA graphic cards? or it is really the difference between cpus? Because definitely, Core i7-4960 is much much more powerful than Pentium G860.</p>
  
  <p>Intel OpenCL Drivers are installed on both computers. For the nVIDIA system, I am using nvidia opencl 1.1 driver but for AMD one, I am using AMD APP SDK 3.0. Can be some difference due to that?</p>
