Last year, Samsung released the industry’s first mobile GPU with hardware-accelerated ray tracing capability. The company teamed up with AMD to develop the Xclipse 920 GPU for its Exynos 2200 chipset, which powered the Galaxy S22 series. The two firms have continued their partnership for mobile GPUs based on AMD’s Radeon graphics technology. Meanwhile, Samsung seems to be working on a more advanced ray tracing technology on its own.
Samsung is developing ray tracing tech for Exynos chips
Ray tracing is a graphics technology that simulates the physical behavior of light. It creates realistic lighting effects and reflections on the on-screen objects while gaming. This enables a more immersive gaming experience with graphics akin to the real world. The technology was previously only available on PC graphics but is slowly making its way into mobile GPUs. It isn’t perfect but each new generation has come with improvements.
According to the Korean media, Samsung’s R&D unit SAIT (aka Advanced Institute of Technology) is developing a couple of advanced technologies to improve the ray tracing capability of its next-gen mobile GPUs: Neural Ray Reconstruction and Neural Super Sampling. The former helps fill in the light rays that are lacking in an image. This ensures a more realistic ray tracing in games and videos.
The latter tech lowers the burden on the system by speeding up image processing with upsampling. It converts low-quality images to high-quality while preserving all the details. Thanks to the anti-aliasing technology, edge lines in games and videos appear smooth for a more realistic effect. All of this works in tandem to enable more advanced ray tracing without increasing the burden on your phone’s graphics resources.
Samsung’s “dream chip” may boast this tech
SAIT is currently working on this project. The plan is to achieve better results than NVIDIA and AMD’s ray tracing tech. Unsurprisingly, it will take time. The company doesn’t expect the solution to be ready before 2025. That is when the Korean firm is expected to debut its first “dream chip” for Galaxy flagships. The 3nm SoC will be custom-built by Samsung’s smartphone division for the Galaxy S25 series.
To achieve the desired results, the SoC must feature a powerful network processing unit (NPU) too. So Samsung has a lot of work to do before realizing its dream chip. Preparations have already begun, with next year’s Galaxy S24 series touted to offer unmatched on-device AI capabilities. It remains to be seen whether the Korean behemoth will be able to fully develop its next-gen ray tracing technology by 2025.
