Hardware-accelerated ray tracing appeared on desktop GPUs a few years ago. It is part of the current generation of game consoles, and this exciting technology will enter smartphones next year Samsung’s upcoming Exynos 2200 GPU is based on AMD’s rDNA 2 architecture, it will retain ray tracing support for desktop and laptop GPUs.
Ray tracing is a physically accurate simulation of how light bounces off objects. Therefore, compared with traditional 3D model lighting methods, it can create more realistic reflections, as well as more realistic lighting and shadows. However, the computational cost of ray tracing is high, so using it in games requires hardware support to achieve real-time performance.

The GPU will also support variable-rate shading, which allows it to render some objects at a higher quality than other objects (such as player characters, background texture and color calculations, or running at a quarter resolution).
The Exynos 2200 GPU is expected to be 30% faster than the current top Mali GPU, which should make it slightly ahead of the upcoming Mali-G710. The final performance will depend on the clock speed that Samsung can achieve in the final chip design.
RDNA 2 is used in the Radeon RX 6000 graphics card, PlayStation 5 and Xbox Series S/X game consoles (with some adjustments), the APU inside the Steam Deck, and even the entertainment system for the new Tesla Model S and X cars support.
