The Intel Arc A770 is the objective winner of this comparison, securing victories in eight out of fourteen evaluated specifications. Its most significant advantage over the NVIDIA RTX 3090 is its AV1 encoding capability, which provides a 100% improvement in that specific metric. While the NVIDIA RTX 3090 maintains a substantial lead in raw processing power, the Intel Arc A770 offers a superior feature set across the majority of the measured technical categories.

Users who prioritize advanced media encoding workflows should choose the Intel Arc A770 to leverage its superior AV1 performance. Conversely, those who require maximum raw graphical throughput should select the NVIDIA RTX 3090, which benefits from a 156% advantage in shader units. Selecting between these two components depends entirely on whether your primary computing needs favor the specialized encoding efficiency of the Intel card or the high-density shader architecture provided by the NVIDIA option.
