Great answer, @Pivot! For reference, this Apple doc defines these terms:

• Renderer Utilization %. The percentage of time the GPU spent performing fragment processing.
• Tiler Utilization %. The percentage of time the GPU spent performing vertex processing and tiling.
• Device Utilization %. The percentage of time the GPU spent doing any tiling or rendering work.
