DLSS 3 not only increases the number of frames but also saves power? Comparison of actual measurements of games

With the launch of RTX 4060 Ti, RTX 40 series dual-fan short cards began to come to the fore, meeting the needs of some users pursuing low-power lightweight graphics cards.

Thanks to the excellent energy consumption ratio of the new generation of graphics cards, the new RTX 40 series products not only significantly improve the game performance compared with the previous generation, but also lower TGP power consumption.

such asThe default TGP power consumption of Yingchi RTX 4060 Ti star accolade OC is 160W, while the default TGP power consumption of 3060mm TGP is 200W, while the former can provide a stronger frame number performance.

On this basis, RTX 40 graphics cards can also greatly increase the number of frames through DLSS 3“ frame generation-rdquo; technology, providing multiple frames in some games.

And when DLSS is enabled, the power consumption is lower than that without DLSS.

Why does the number of frames increase and the power consumption become lower when DLSS is enabled?

All this depends on whether AI,NVIDIA DLSS is a & nbsp;AI  super-resolution algorithm accelerated by & nbsp;Tensor Core  based on & nbsp;GeForce RTX GPU .

Super resolution is the process of accurately predicting higher resolution output (for example, 4K) through lower resolution inputs (for example, 1080p). In this way, the game can be rendered at 1080p, thereby increasing the frame rate, and then using AI and game engine data to provide the image quality of the native 4K output.

In other words, the resolution load of the video card running the game is smaller, and the power consumption of running the game is less than the native resolution.

Similarly, DLSS 3 also uses AI, on the basis of DLSS 2, uses optical multi-frame generation technology, and can generate more frames with the help of AI.

DLSS 3 analyzes the continuous frame and motion data of the new optical flow accelerator in the GeForce RTX 40 series GPU to generate other high-quality frames without affecting picture quality and response speed.

For each frame, the DLSS frame generation AI determines how to generate intermediate frames using information from the game motion vector, optical flow field, and subsequent game frames. By using a combination of game motion vectors and optical flow to track motion, the AI network generated by DLSS frames can accurately reconstruct geometry and effects, as shown in the following illustration.

When DLSS  3 is enabled, AI reconstructs 3/4 of the first frame using DLSS super-resolution and the complete second frame using DLSS frame generation.

Taken together, DLSS 3  rebuilds 7/8 of all display frames, significantly improving performance! All this, compared with DLSS, is carried out at a lower power consumption. DLSS can bring a significant increase in the number of frames, and there is basically no difference between the frame generated picture and the original picture.

There are more than 400 games and apps that support RTX and 300 games and apps that support DLSS, including more than 50 games that have launched or are about to support DLSS 3, and cover many popular new games, such as Diablo 4, which will be released in June.

The application speed of DLSS 3 is very fast, and more games supporting DLSS 3 will be launched in the future. Please look forward to it.
