thanks for the links. I was aware that they make use of it, just not how much. I recently got a Haswell i7 and was hoping to see more perf; the devs use Intel GPUs as well, and Haswell/Iris have very good OpenCL performance. Maybe their OpenCL work will make a notable difference in future versions.

> Haswell/Iris have very good OpenCL performance. Not on Linux. Intel only supports using OpenCL on the Xeon Phi coprocessors if you're using Linux. Iris OpenCL support is restricted to Windows.

  well that sucks. I'm curious, is that a driver limitation? how do they restrict it from working in linux?

    Intel simply doesn't provide an OpenCL implementation on Linux, and there's no free one (as yet, and for the future). OpenCL support on Linux is an unmitigated disaster; I worked with it this summer in a different KDE program. I wouldn't get your hopes up.

      after reading around a bit [1], I get the impression that while the situation isn't great, it isn't a hopeless disaster, either. Apparently there's Linux drivers but only x64, and not in a Ubuntu-friendly format. Hopefully this will change. I'll play around with it a bit, to see how bad it really is first hand :-) thanks [1] http://mhr3.blogspot.ie/2013/06/opencl-on-ubuntu-1304.html http://mhr3.blogspot.ie/2013/06/opencl-on-ubuntu-1304.html Edit: apparently the drivers that are available for Linux don't support HD or Iris GPUs.
