The Intel Arc A580 is the objective winner of this comparison, securing a higher number of superior specifications across the evaluated fields. Its most significant advantage is a 60% wider memory bus compared to the alternative. While the Intel Arc B570 holds its own in several categories, the A580 provides a more robust foundation in terms of raw hardware architecture, making it the more capable choice based on the total count of winning specifications.

Users prioritizing memory bandwidth should select the Intel Arc A580 for its substantial 60% advantage in that area. Conversely, those who place a higher value on software-driven upscaling technology should opt for the Intel Arc B570, which features a 54% more advanced version of XeSS. Choosing between these two components depends entirely on whether your specific workload benefits more from the memory bus capacity of the A580 or the newer upscaling capabilities of the B570.
