The AMD RX 9070 is the objective winner of this comparison, securing victories in nine out of fourteen measured specifications. Its most significant advantage over the Intel Arc B580 is its Ray Accelerators, which provide a 180% improvement in that specific category. This substantial lead in ray acceleration hardware positions the AMD RX 9070 as the superior choice for users prioritizing advanced lighting and rendering capabilities within their graphical workloads.

Users who require high-end ray tracing performance should select the AMD RX 9070 to leverage its significant hardware advantage. Conversely, the Intel Arc B580 is the appropriate choice for those who prioritize a higher base clock speed, as it outperforms the competitor by 101% in that metric. Choosing between these two components depends entirely on whether your specific use case benefits more from the superior ray acceleration of the former or the increased base clock of the latter.
