The Intel Arc A310 is the objective winner of this comparison, securing victory in seven out of twelve measured specifications. While the AMD RX 570 maintains a significant lead in memory bandwidth, the Intel Arc A310 provides the most impactful advantage with its superior AV1 encoding capability, which is 100% better than the alternative. This technical edge makes the Intel card a more modern and efficient choice for specific multimedia tasks despite the deficit in raw memory bus width.

Users prioritizing modern video processing and encoding workflows should select the Intel Arc A310 to leverage its advanced AV1 support. Conversely, those who require a wider memory bus for specific data-heavy operations should choose the AMD RX 570. The decision rests on whether your primary objective is utilizing the latest encoding standards or benefiting from the 300% wider memory bus provided by the AMD hardware.
