I am trying to compare OpenCL kernel performance on some different CPUs, and I would like to use the same device version for this. For the machines that don't have an Intel GPU, I am using the CPU only runtime (220.127.116.1116), which makes the CPU Device report "OpenCL 1.2 (Build 80752)" as the version. That's all fine and good. But one of my machines is an i7-4700EQ with 4600 Graphics. I understand that for this machine, the CPU device support is also provided through the Graphics driver. The latest graphics driver I can find (10.18.10.3412) seems to have an older CPU driver associate with it: The CPU device reports device driver version 18.104.22.16878, the device version is "OpenCL 1.2 (Build 76413)". This seems substantially older.
So here's my question: Is there anything I can do to get a newer driver for the CPU device, or am I stuck with waiting for the Graphics driver to catch up to where the CPU only runtime is now? Or should I downgrade the CPU driver on my other test machines? It would be really good to compare apples and apples here.
Thank you very much!
