The AMD RX 6400 is the objective winner of this comparison, securing a victory in nine out of twelve evaluated specifications. Its most significant advantage over the NVIDIA GeForce GTX 1050 is its VRAM capacity, which is 100% higher. This substantial increase in memory provides the AMD RX 6400 with a clear technical lead across the majority of the measured categories, establishing it as the superior component based on the provided hardware data.

Users prioritizing memory capacity should select the AMD RX 6400 to take advantage of its doubled VRAM. Conversely, the NVIDIA GeForce GTX 1050 remains the appropriate choice for those who specifically require a superior memory bus, as it offers a 100% advantage in that single metric. Your final decision should depend on whether your specific workload benefits more from the increased memory pool of the former or the wider memory bus of the latter.
