GPU Performance

It is time to grab a number of cards and look per API on how the performance is. So basically what we are doing here is running the very same test, just on a different API. With NVIDIA dominating the enthusiast market, it's hard to compare really. We see a fairly good performance, however, let's move towards DirectX 12, remember this is the same workload, just rendered on a different API.

Performance jumps up significantly with the D3D12 API. But let's load up the last API we test, VULKAN below

You can clearly see the cards jump up further in performance when on Vulkan. Interestingly enough, the latest generation NVIDIA graphics card seems to go stronger on VULKAN where The last-gen Radeons seem to appreciate DX12. Is does carry a little bit here and there though. 

Above we compare DXR versus VULKAN 1.2 on the Radeon RX 6000  series cards.

Above we compare DXR versus VULKAN 1.2 on the GeForce RTX  series cards.

Concluding

That concludes this writeup; from today, basemark GPUScore is accessible for download and testing. It is a program for measuring GPU performance across many platforms. For Guru3D, testing a smartphone or tablet on Android isn't that important, thus we're more interested in the basemark GPUScore for VULKAN API testing.  We may end up utilizing Basemark GPUScore Relic of Life in our graphics card test suite because it provides a pretty good and rapid comparison across APIs that you can also test at home.
