Comparison of Titan V vs. Titan RTX for ray tracing


The NVIDIA Titan V graphics card is fully capable of working with real-time ray-tracing in games, although it does not have dedicated RT cores. One of the users of the 3DCenter resource was discovered under the pseudonym TobiWahnKenobi, who also compared the performance "Titans" generations of Volta and Turing during real-time ray-tracing processing.

In fact, Titan V's ability to handle ray-tracing in real time has been known for some time, because it was this graphics card that game developers used to test the track before the appearance of Turing. However, recent tests have shown that Titan V demonstrates very high performance in ray tracing and is not so far from the Titan RTX video card.

The tests were conducted in the Battlefield V game in the resolution of 1440r (2560 × 1440 pixels) with the maximum graphic settings (Ultra). On a board called "Ridge 652" (Fjell 652) at maximum ray tracing intensity, Titan RTX provided an average of 87 frames / s, while Titan V could provide 80 frames / s. But in all honesty it should be noted that there are not too many reflecting surfaces on a snowy mountain map, so the number of beams was not very high.

In turn, on the map "Rotterdam" (Rotterdam), where there are many windows of houses, puddles and other reflecting surfaces, the difference between the two "Titans" was already more tangible. With an average intensity of beam tracking, Titan RTX showed an average result of 97 fps, while Titan V has about 67 fps. At maximum intensity, the results were 81 and 56 fps, respectively, or the difference decreased slightly.

Obviously, Titan V uses conventional CUDA ray tracing cores, which has more than Titan RTX (5120 vs. 4608 cores), which somehow compensates for the absence of RT cores. In addition, Battlefield V uses only ray tracing to create reflections, while other projects using ray tracing will also use it to create global lighting, create shadows and other activities. Thus, in such scenarios, the difference between the "Titans" of the Volta and Turing generations could be much wider.
