The Intel Arc A580 is the objective winner of this comparison, securing a lead in nine out of fourteen measured specifications. Its most significant technical advantage is a memory bus that is 100% better than that of the competition. While the AMD RX 6650 XT holds its own in specific areas, the Intel card demonstrates a broader superiority across the majority of the evaluated hardware metrics, establishing it as the more robust option based on these technical specifications.

Users prioritizing raw memory bandwidth should choose the Intel Arc A580 to leverage its substantial advantage in that category. Conversely, the AMD RX 6650 XT is the preferred selection for those who specifically require superior ray tracing hardware, as it features 33% more ray accelerators than the alternative. Your final decision should depend on whether your primary workload demands the expanded memory bus of the Intel hardware or the specialized ray tracing capacity of the AMD component.
