The Intel Arc A770 is the objective winner of this comparison, securing victories in twelve out of thirteen measured specifications. Its most significant technical advantage is its FP16 performance, which is 21744% better than that of the NVIDIA GTX 1080 Ti. This massive disparity in floating-point capability highlights the generational shift in architecture between the two components, establishing the Intel Arc A770 as the superior option across the vast majority of evaluated hardware metrics.

Users prioritizing modern architectural features and raw computational throughput should choose the Intel Arc A770 for its comprehensive spec-based dominance. Conversely, the NVIDIA GTX 1080 Ti remains a viable alternative for specific use cases that rely heavily on memory bandwidth, as it maintains a 38% advantage in memory bus width. Select the former for broad technical superiority or the latter if your specific workload demands the higher memory bus capacity provided by the NVIDIA card.
