The Intel Arc A380 is the objective winner of this comparison, securing victories in nine out of thirteen measured specifications. Its most significant advantage over the AMD RX 570 is its support for AV1 encoding, which is 100% better than the alternative. While the AMD RX 570 maintains a notable lead in memory bus width, outperforming the Intel card by 167%, the overall spec-based advantage clearly favors the newer architecture provided by the Intel Arc A380.

Users prioritizing modern media workflows and advanced video encoding capabilities should select the Intel Arc A380 for its superior AV1 support. Conversely, those who require a wider memory bus for specific data-heavy tasks will find the AMD RX 570 to be the more suitable choice. Your final decision should depend on whether your primary workload relies on the increased memory bandwidth of the AMD RX 570 or the modern encoding features found in the Intel Arc A380.
