The Intel Arc B580 is the objective winner of this comparison, securing victories in eleven out of thirteen measured categories. Its most significant technical advantage over the NVIDIA GTX 1070 is its FP16 performance, which is 27240% higher. This massive disparity in floating-point capability establishes the Intel Arc B580 as the superior component across the vast majority of the evaluated hardware specifications.

Users prioritizing raw computational throughput and modern hardware standards should choose the Intel Arc B580 for its comprehensive spec-based lead. Conversely, the NVIDIA GTX 1070 remains a viable option for specific use cases that rely heavily on memory bandwidth, as it maintains a 33% advantage in memory bus width. Select the former for broad performance gains or the latter if your specific workload demands the wider memory bus provided by the older architecture.
