RTX and DLSS
Being an RTX card I also like checking out the performance of some of Nvidia’s features. Namely the ray tracing performance and the performance improvements you can see by using DLSS combined with the tensor cores. My first test goes back to our synthetic benchmarks with 3DMark where I check out their Port Royal benchmark. This is the one test that does also have AMD Ray Tracing support which is great to get a look at how different cards including older non-RTX cards perform. The Zotac RTX 4070 Amp Airo improved on the 4070 scores with its 11340 which got extremely close to the 11364 score of AMDs last generation flagship, the AMD 6950 XT.
3DMark also has added in a few feature tests, one being a look at DLSS performance. For this one, I have the resolution set to 4K and I test with all three versions of DLSS as well as with it off completely. All DLSS are set to their performance setting as well to keep the results comparable. This gives us a great look at the performance improvements that DLSS has given with DLSS 3 also including frame generation. The Zotac RTX 4070 Amp Airo once again is at the top of the chart for the RTX 4070s. This chart though is mostly just a good look at the performance improvements possible with DLSS especially through the generations with having it off to DLSS 1 doubling performance, DLSS 2 tripling the original frame rate, and DLSS 3 with frame generation doing four times the frame rate going from 23.26 FPS up to 86.05 FPS.
I then jumped into game tests, this time with Watch Dogs: Legion. For this one, I wanted to get an idea of the performance you will see when taking advantage of Nvidia’s RTX and DLSS features. I tested at 4k with the ultra detail setting and with ultra being the setting for DLSS and RTX when they are on as well. I then test with no RTX or DLSS on and then with RTX DLSS on and off and on together. Here the Zotac RTX 4070 Amp Airo matched the other 4070s with the no RTX or DLSS test and with RTX on. It's one FPS lower than the Founders Edition on the combined result and then matched the Ventus with the DLSS-only result.
Next, I wanted to check out the performance in Metro Exodus which we have used for testing for a long time now. This test is similar as well with it set to 4K and Ultra detail, I use the included benchmark to test DLSS and RTX individually and then with them both on and both off to give us a look at overall frame rates depending on which direction you go. I should point out that this is using the Enhanced Edition where our normal benchmark uses the standard version for testing with AMD but that version DLSS no longer works. That said the Zotac RTX 4070 Amp Airo does edge out the other 4070s in all of these tests.
