Every scene draws at 1920 by 1080, whatever the screen. A scene under 8.0 ms there is too light for the chip and runs again at a heavier load: at 3840 by 2160, as the row named with _2160p, or, for compute_nbody, with 2 times the particles, as the row named with _2x. hdr runs at the larger picture only. Compare drivers on one device; across devices, compare only rows that kept the GPU busy.
Graphics chip below 90% of its top speed (GPU clock) during: compute_nbody, pipeline_barriers, pipeline_barriers_2160p. The device was holding the graphics chip back (heat or a power-saving mode), or the scene is too light to need more. Compare these numbers only with a run at a similar clock.
