The Intel Arc A770 is the objective winner of this comparison, securing victory in eleven out of sixteen measured categories. Its most significant advantage over the Intel Arc A380 is its FP32 performance, which is 368% higher. While the Intel Arc A380 maintains a lead in power efficiency with a TDP that is 67% better, the substantial computational superiority of the Intel Arc A770 makes it the clear leader in raw processing capability.

Users prioritizing maximum computational power should choose the Intel Arc A770 for its vastly superior FP32 performance. Conversely, those building systems where power consumption is the primary constraint should opt for the Intel Arc A380. By selecting the Intel Arc A380, users benefit from a significantly lower TDP, whereas the Intel Arc A770 is the appropriate choice for tasks requiring the highest level of performance across the majority of measured specifications.
