RX 590 wins in 5 specs (Memory Bus: 300% better).
Recommendation
Choose RX 6400 if you want the best overall performance — especially tdp.
Choose RX 590 if memory bus matters more to you.
AI Versus Verdict
The AMD RX 6400 is the objective winner of this comparison, securing a higher number of superior specifications across the evaluated fields. Its most impactful advantage is its thermal design power, which is 70% better than that of the alternative. While the AMD RX 590 maintains a significant lead in memory bus width, offering a 300% advantage in that specific category, the overall spec-win count favors the newer card for its efficiency-focused design.
Users prioritizing power efficiency and lower thermal output should select the AMD RX 6400 for their system. Conversely, those who require a wider memory bus for specific data-heavy tasks will find the AMD RX 590 to be the more suitable choice. Your decision should depend on whether you value the superior power management of the former or the substantial memory bus advantage provided by the latter.
