I'm running Power Gadget 3.5.2 on Sierra on my late-2013 Retina MacBook Pro, as well. (You should be able to find it with a Google search if it's not on the Intel website.) From a preliminary test, it looks like my laptop throttles way, way down when doing any real work (i.e. 4Kx4K stereoscopic renders in Premiere Pro or Mistika VR).Are you sure about that? I ran the previous 3.5.2 Power Gadget release on Sierra on my 2015 MacBook Pro Retina 15".
