RT Cores are specialized hardware components found in modern graphics processing units (GPUs) designed to accelerate real-time ray tracing. Ray tracing is a rendering technique that simulates how light interacts with objects to create highly realistic images. By using RT Cores, GPUs can calculate complex lighting effects, shadows, and reflections more efficiently than traditional rendering methods. These cores are particularly beneficial in applications like video games and visual effects, where realistic graphics are essential. With the introduction of NVIDIA's RTX series, RT Cores have become a standard feature, enabling developers to create immersive environments with stunning visual fidelity.
