Heh those Doom benchmarks are not consistent with other people's testing, nor my own experience. The 480 is way faster in Vulkan.
I googled the most recent benchmarks I could. My link was dated end oct 16. Like the 480 the 1060 has also had driver updates which effectively closed the Vulcan gap. Now by all means post me a more up to date set of benchmarks which shows otherwise as I'm genuinely interested!
