29-Way GPU Comparison On Linux From Kepler & Cypress To Today's Pascal & Vega

Dota 2 at 1080p is very CPU bound, but for those wondering about the performance with the outdated graphics cards...

While still CPU bound, here are the Vulkan numbers too for going back to Kepler on the NVIDIA side with their Vulkan support while the Vulkan support on Radeon ends with GCN 1.0 when using the AMDGPU DRM driver. These results while CPU bound do show the NVIDIA Vulkan driver appearing to be faster than the RADV driver, at least less overhead.

Dawn of War III with Vulkan is another case where you can see the RADV driver still topping out lower than the NVIDIA Vulkan driver.
