The AMD RX 9060 is the objective winner of this comparison, securing victory in eight of the thirteen measured categories. While the AMD RX 580 maintains a significant lead in memory bus width, doubling the capacity of its counterpart, the newer model dominates in computational efficiency. The most impactful advantage for the AMD RX 9060 is its FP16 performance, which represents a massive 627% improvement over the older hardware, fundamentally changing the processing capabilities between these two units.

Users prioritizing raw computational throughput and modern processing efficiency should select the AMD RX 9060 to leverage its superior FP16 performance. Conversely, the AMD RX 580 remains the logical choice for specific applications that rely heavily on a wider memory bus, where its 100% advantage provides a distinct architectural benefit. Choosing between these components depends entirely on whether your workload demands the high-speed memory interface of the older card or the vastly improved computational power of the newer one.
