Previous leaks claimed that the PlayStation 6's ray tracing performance was ten times that of the PS5, but KeplerL2 has now pointed out that the PS6's actual game frame rate improvement is about three times that of the PS5. That said, what should you know about it?
Even if there’s 10 times the improvement, it doesn’t exactly increase the frame rate
For your information, KeplerL2 used official data from Ubisoft's Assassin's Creed: Shadows as an example to estimate that the base PS5 runs stably at 30 FPS in ray tracing mode, and the rendering time outside of ray tracing is about 25ms.
Moreover, if the PS6's ray tracing performance is indeed improved by 10 times, the ray tracing time will drop from about 5ms to 0.5ms. Combined with the non-ray tracing time being reduced proportionally to about 8.33ms, the total frame time will be about 9.68ms, corresponding to about 103 FPS. From 33 FPS to 103 FPS, the actual frame rate improvement is about 3.1 times.
Additionally, the core issue is that even with a 10x improvement in ray tracing performance, ray tracing calculations only account for a portion of the total rendering time in a single frame. In games with a lighter ray tracing load, rasterisation and calculations still account for more than 50% of the frame time. Therefore, a 10x improvement in ray tracing cannot be proportionally converted into a frame rate increase.
Moreover, KeplerL2 added that the performance gap between PS6 and PS5 will be greater in games with heavier ray tracing or path tracing loads, but even then, it will be far from a 10x frame rate increase. "Rasterisation/computation typically still accounts for more than 50% of frame time, so 10x ray tracing will never bring a close to a 10x frame rate increase.
