RX 6400 wins in 3 specs (TDP: 80% better).
Recommendation
Choose RX 7800 XT if you want the best overall performance — especially fp32 performance.
Choose RX 6400 if tdp matters more to you.
AI Versus Verdict
The AMD RX 7800 XT is the objective winner of this comparison, securing victory in twelve out of fifteen measured specifications. While the AMD RX 6400 maintains a notable lead in power efficiency with an 80% better TDP, the AMD RX 7800 XT dominates in raw computational power. The most impactful advantage for the AMD RX 7800 XT is its FP32 performance, which is 948% better than that of the alternative, representing a massive disparity in processing capability.
Users prioritizing extreme computational throughput and high-end performance should select the AMD RX 7800 XT for their builds. Conversely, the AMD RX 6400 is the superior choice for those who require a low-power solution where TDP is the primary concern. By choosing based on these specific advantages, users can align their hardware selection with either the high-performance processing needs met by the former or the power-efficient requirements satisfied by the latter.
