The Intel Arc B580 is the objective winner of this comparison, securing victories in twelve out of fourteen measured specifications. The most impactful advantage for this card is its AV1 Encoding capability, which is 100% better than that of the AMD RX 6650 XT. While the latter component maintains a lead in ray tracing hardware, the Intel Arc B580 dominates the majority of the technical categories evaluated, establishing itself as the superior option based on the provided data.

Users who prioritize advanced video encoding workflows should choose the Intel Arc B580 to leverage its significant lead in that specific area. Conversely, the AMD RX 6650 XT remains the preferred selection for those who specifically require superior ray tracing performance, as it offers a 60% advantage in Ray Accelerators. Buyers should weigh these two distinct hardware strengths against their primary computing needs to determine which of these graphics cards best aligns with their intended use case.
