NVIDIA Perf 1080p
For the upper-low-end, to low-end video cards, we ran the benchmark first at 1080p with “Ultimate” game settings applied. None of these video cards have 8GB of VRAM, they have 6GB or 4GB. At “Ultimate” they are all in the red according to the in-game VRAM counter. This also shows here in the results as the results are a lot less than if they weren’t VRAM bottlenecked.
The GeForce GTX 1660 Ti does show that Vulkan is 8% faster than DX11. GeForce GTX 1660 SUPER shows Vulkan is 7% faster than DX11. The odd duck is the VRAM bottlenecked GeForce GTX 1650 SUPER with 4GB of VRAM. That video card actually went backwards a bit in performance. It is understandable though because it is completely VRAM bottlenecked, just like the 4GB Radeon RX 5500 XT at “Ultimate” settings at 1080p. So let’s lower settings and see what happens.
In this graph, we have now lowered game settings to “Medium” quality. This removes the VRAM limitations as it uses less than 4GB of VRAM. You can see that the GeForce GTX 1650 SUPER is now vastly improved in performance and Vulkan shows to be 9% faster than DX11. GeForce GTX 1660 SUPER shows Vulkan to be 16% faster than DX11. GeForce GTX 1660 Ti shows Vulkan to be 15% faster than DX11. These are very nice improvements in the lower quality settings.
