The Intel Arc A310 is the objective winner of this comparison, securing victory in seven out of twelve evaluated specifications. Its most significant technical advantage is the inclusion of AV1 encoding, which represents a 100% improvement over the NVIDIA GTX 1660 SUPER. This superior encoding capability positions the Intel card as the more modern option for users prioritizing advanced media processing and efficient video streaming workflows over traditional hardware architecture.

Users should choose the Intel Arc A310 if their primary focus is utilizing AV1 encoding for high-quality video production and modern media tasks. Conversely, the NVIDIA GTX 1660 SUPER remains the better selection for those who require a significantly wider memory bus, which is 200% better than the alternative. Selecting between these two components depends entirely on whether your specific workload demands the latest encoding standards or the increased data throughput provided by the larger memory interface.
