Core i3 vs. Core i5 Performance Impact On OpenGL/Vulkan Linux Gaming

For a while now there have been some requests to post GPU benchmarks from some modern low-end and higher-end CPUs while testing different graphics cards, particularly to see the impact of the Vulkan API. With all the recent Kabylake testing, I've run some open-source AMD graphics tests using a Core i3 7100 and Core i5 7600K for those that may be weighing CPU options for a Linux gaming system upgrade.
