The Intel Arc B580 is the objective winner of this comparison, securing victory in ten out of twelve measured categories. Its most significant advantage is its FP32 performance, which is 1029% higher than that of the AMD Radeon RX 550. While the latter component maintains a lead in power efficiency, the substantial gap in raw computational capability establishes the Intel Arc B580 as the superior hardware option based on the provided specifications.

Users prioritizing raw processing power should select the Intel Arc B580 for their system builds. Conversely, the AMD Radeon RX 550 is the appropriate choice for those who specifically require a lower power draw, as it offers a 74% advantage in TDP. By evaluating these two distinct strengths, buyers can align their selection with either the high-performance output of the Intel card or the energy-conscious design of the AMD alternative.
