In regard to your inquiry about the Intel® HD Graphics 6100, I just wanted to confirm that yes, they do support OpenCL 2.0, as you can confirm on the following link:
Now, Apple has requested that all questions regarding Apple systems and software be addressed directly with Apple support.
So, I recommend checking the links below for further troubleshooting assistance on your Apple computer:
Any further questions, please let me know.
Thank you for your note.
However the question I posted in this forum wasn't specific to Apple products, but was a question directed towards OpenCL support on 5th Generation Intel Processors (e.g. Intel Iris Graphics 6100). Likely the same "2X"-graphic speed differential (below) is seen on ALL platforms (Linux, Windows, Apple), so it's important to understand the reason for this differential.
Can Intel specifically answer this question: Do 5th Generation Intel Processors (e.g. Intel Iris Graphics 6100) implement floating point support ("cl_khr_fp64" extension) ????
If NO, then a) is this a software issue that INTEL CORPORATION can resolve? or b) is this a hardware ("deficient silicon") issue that cannot be resolved ????
IF the answer to the question "Do 5th Generation Intel Processors (e.g. Intel Iris Graphics 6100) implement floating point support ("cl_khr_fp64" extension)" is YES, then certainly I will inquire of Apple why processor interrogation says differently, as documented in the following Github URL: https://github.com/cdeterman/gpuR/issues/11
You are welcome.
Thank you very much for letting us know that information.
