The Intel Arc B570 is the objective winner of this comparison, securing victory in thirteen out of sixteen measured specifications. Its most significant advantage over the Intel Arc A380 is its FP32 performance, which is 174% higher. While the Intel Arc A380 maintains a 50% advantage in TDP, the substantial lead in raw computational power makes the Intel Arc B570 the superior choice for users prioritizing high-performance output across the majority of technical categories.

Users who require maximum computational throughput should select the Intel Arc B570 to leverage its significant lead in FP32 performance. Conversely, the Intel Arc A380 remains the appropriate choice for builds where power efficiency is the primary constraint, as it offers a 50% better TDP. By evaluating whether your specific needs prioritize raw processing capability or lower power consumption, you can determine which of these two components best aligns with your system requirements.
