The NVIDIA RTX 5070 Ti is the objective winner of this comparison, securing victories in ten out of thirteen measured specifications. Its most significant technical advantage is its FP16 performance, which is 24311% better than that of the NVIDIA GTX 1080 Ti. While the older card maintains a lead in memory bus width, the massive disparity in floating-point processing capabilities establishes the newer model as the superior component across the vast majority of evaluated hardware metrics.

Users prioritizing raw computational throughput and modern processing efficiency should select the NVIDIA RTX 5070 Ti for their systems. Conversely, the NVIDIA GTX 1080 Ti remains a viable option for specific use cases that rely heavily on a wider memory bus, where its 38% advantage in that particular specification provides a distinct architectural benefit. Choosing between these two components depends entirely on whether your workload favors high-speed memory bandwidth or the vastly superior FP16 performance of the newer architecture.
