Radeon Vulkan Driver Benchmarks: AMDVLK 2018.4.2 vs. AMDGPU-PRO 18.40 vs. Mesa 18.2/19.0

Released this week was AMDVLK 2018.4.2 having been released this past week as the newest open-source AMD Vulkan driver code derived from their official Vulkan driver code-base but with using the AMDGPU LLVM compiler back-end over their proprietary shader compiler. For your latest Vulkan benchmark viewing pleasure is a look at this newest AMDVLK release compared to AMDGPU-PRO 18.40 (the same fundamental Vulkan driver but with the closed-source shader compiler) and then the RADV Vulkan drivers in the form of Mesa 18.2 stable and the now in-development Mesa 19.0. These four AMD Radeon Vulkan driver combinations were tested on Fiji, Polaris, and Vega graphics processors.
