The AMD RX 580 is the objective winner of this comparison, securing victory in eight of the thirteen measured categories. Its most significant advantage over the AMD RX 470 is its VRAM capacity, which is 100% higher. While the AMD RX 470 maintains a lead in power efficiency with a 35% better TDP, the superior memory configuration of the AMD RX 580 makes it the more capable component across the majority of technical specifications.

Users prioritizing memory capacity for their graphical workloads should choose the AMD RX 580 to take advantage of its doubled VRAM. Conversely, those building systems where power consumption is the primary constraint should select the AMD RX 470. By opting for the latter, users benefit from a 35% improvement in TDP, making it the more efficient choice for power-sensitive environments despite the AMD RX 580 leading in most other technical areas.
