Some Pascal vs Turing RTX numbers in recent games:
Call Of Duty Modern Warfare (DXR shadows)
@2160p, 2080Ti is
3 times faster than 1080Ti, the 2060 is 60% faster
@1440p, 2080Ti is
2.2 times faster than 1080Ti, the 2060 is 50% faster
@1080p, 2080Ti is
2 times faster than 1080Ti, the 2060 is 25% faster
Also the 1080Ti is only 25% faster than 1660Ti at all resolutions, indicating the importance of split FP32 and INT32 units in ray tracing performance.
Control (DXR Shadows, Reflections, AO, Indirect Lighting)
@2160p, 2080Ti is
3.7 times faster than 1080Ti, the 2060 is 2 times faster
@1440p, 2080Ti is
3.7 times faster than 1080Ti, the 2060 is 90% faster
@1080p, 2080Ti is
3.2 times faster than 1080Ti, the 2060 is 70% faster
Also the 1080Ti is only 15% faster than 1660Ti at all resolutions, indicating the importance of split FP32 and INT32 units in ray tracing performance.
