The AMD RX 6700 is the objective winner of this comparison, securing victory in seven out of thirteen measured categories. Its most significant technical advantage is its FP16 performance, which is 217% better than that of the alternative. While the AMD RX 590 maintains a notable lead in memory bus width, offering a 60% advantage in that specific area, it falls behind in the majority of the evaluated hardware specifications.

Users prioritizing raw computational throughput for modern tasks should choose the AMD RX 6700 due to its superior FP16 performance. Conversely, the AMD RX 590 remains a viable option for specific workloads that rely heavily on a wider memory bus. Your final decision should depend on whether your primary requirements favor the high-speed processing capabilities of the newer model or the specific memory architecture advantages provided by the older card.
