AI Versus Verdict
The AMD RX 6700 is the objective winner of this comparison, securing nine spec victories compared to three for the AMD RX 6400. The most significant advantage for the AMD RX 6700 is its FP32 performance, which is 217% better than the alternative. Conversely, the AMD RX 6400 maintains a distinct lead in power efficiency, offering a TDP that is 70% better than the higher-performing card.
Users prioritizing raw computational power should select the AMD RX 6700 to leverage its superior FP32 performance. This card is the clear choice for demanding tasks where processing capability is the primary requirement. Alternatively, those building systems with strict power constraints or limited thermal headroom should choose the AMD RX 6400. Its significantly lower TDP makes it the ideal option for energy-efficient builds where power consumption is the most critical factor.
