The AMD RX 6400 and the NVIDIA GTX 1070 reach a stalemate in this comparison, as both components secure an equal number of specification victories. While the overall performance profile is balanced, the most significant technical disparity lies in the FP16 performance, where the AMD RX 6400 maintains a massive 7030% advantage. Conversely, the NVIDIA GTX 1070 holds a substantial lead in memory architecture, boasting a memory bus that is 300% wider than its competitor.

Users prioritizing high-speed floating-point operations for specialized tasks should select the AMD RX 6400 to leverage its superior FP16 capabilities. Alternatively, those who require a significantly wider memory bus for data throughput should choose the NVIDIA GTX 1070. Because neither card emerges as a clear objective winner across all measured fields, the final decision depends entirely on whether your specific workload benefits more from the AMD card's compute efficiency or the NVIDIA card's memory bandwidth.
