The NVIDIA RTX 5050 Mobile is the objective winner of this comparison, securing victory in six out of seven measured specifications. Its most significant advantage over the AMD RX 6400 is its shader unit count, which is 233% higher. While the AMD RX 6400 maintains a lead in power efficiency with a 47% better TDP, the substantial disparity in core processing hardware makes the NVIDIA RTX 5050 Mobile the superior component across the majority of technical categories.

Choose the NVIDIA RTX 5050 Mobile if your priority is maximizing shader unit capacity for your graphical workloads. Conversely, select the AMD RX 6400 if your primary requirement is the power efficiency provided by its superior TDP. By focusing on these specific technical advantages, you can align your choice with either the raw processing power of the NVIDIA hardware or the lower power consumption profile offered by the AMD alternative.
