Radeon RX 580: AMDGPU-PRO vs. DRM-Next + Mesa 17.2-dev

Last week I posted initial Radeon RX 580 Linux benchmarks and even AMDGPU overclocking results. That initial testing of this "Polaris Evolved" hardware was done with the fully-open Radeon driver stack that most Linux enthusiasts/gamers use these days. The AMDGPU-PRO driver wasn't tested for those initial articles as it seems to have a diminishing user-base and largely focused for workstation users. But for those wondering how AMDGPU-PRO runs with the Radeon RX 580, here are some comparison results to DRM-Next code for Linux 4.12 and Mesa 17.2-dev.
