The AMD RX 6400 is the objective winner of this comparison, securing victories in seven out of twelve measured specifications. Its most significant advantage over the competition is its FP32 performance, which is 67% higher. This substantial lead in raw computational capability establishes the AMD RX 6400 as the superior option for users prioritizing modern processing power within this specific hardware tier.

Users should choose the AMD RX 6400 if they require the highest available FP32 performance for their computing tasks. Conversely, the NVIDIA GeForce GTX 1050 Ti remains the appropriate selection for those who specifically prioritize a wider memory bus, as it offers a 100% advantage in that category. Selecting between these two components depends entirely on whether your workload benefits more from the increased computational throughput of the former or the memory architecture of the latter.
