With the Exynos 2200, ray tracing is coming to mobile games, Samsung says

Hardware-accelerated ray tracing appeared on desktop GPUs a few years ago, it is part of the current generation of consoles and will arrive on smartphones next year – Samsung’s upcoming Exynos 2200 GPU is based on AMD’s RDNA 2 architecture and will keep the ray tracing support of the desktop and laptop GPUs.

AMD CEO Lisa Su announced earlier this year that the company was working with Samsung to bring ray tracing to smartphones. In a recent Weibo post, Samsung announced that its next-generation Exynos 2200 chipset will be the first to support ray tracing.

Highlights

  • Ray tracing is computationally expensive, however, so using it in games requires hardware support to achieve real time performance.

  • Ray tracing is a physically accurate simulation of how light bounces off objects, so it creates much more realistic reflections but also more photo-realistic lighting and shadows compared to the traditional method of lighting 3D models.

The Exynos 2200 GPU is expected to be up to 30% faster than the current top Mali GPU, which should put it slightly ahead of the upcoming Mali-G710 as well. The final performance will depend on the clock speed that Samsung is able to achieve with the final chip design.

The GPU will also support Variable Rate Shading, which allows it to render some objects (e.g. the player character) with higher quality than others (e.g. texture and color calculations for the background run at quarter resolution).

RDNA 2 is used in the Radeon RX 6000 graphics cards, the PlayStation 5 and Xbox Series S/X consoles (with some tweaks), the APU inside the Steam Deck and even powers the entertainment system of new Tesla Model S and X cars.

The microprocessor, dubbed “Pamir,” is likely to be introduced early next year. The Exynos 2200 is believed to contain a single high-performance core, three mid-tier cores, and four efficiency cores, similar to the Exynos 2100.

According to rumors, the GPU might have 384 Stream Processors, which would indicate six Ray Accelerators. In terms of gaming, Ray tracing capability will undoubtedly offer the Exynos 2200 a little advantage over Qualcomm’s anticipated Snapdragon 898. The processor will be used in international variations of Samsung’s Galaxy S22 series phones.

The Galaxy Tab S8 Ultra, Samsung’s next premium Android tablet, is also reported to have the same processor.
