The Intel Arc B580 is the objective winner of this comparison, securing victories in ten out of thirteen measured specifications. Its most significant technical advantage is its base clock speed, which is 102% higher than that of the NVIDIA GeForce RTX 3060 8 GB. This substantial lead in clock frequency positions the Intel Arc B580 as the superior option across the majority of the evaluated hardware metrics.

Users prioritizing raw clock speed should select the Intel Arc B580 for its clear advantage in that category. Conversely, those who require a higher count of shader units should opt for the NVIDIA GeForce RTX 3060 8 GB, as it maintains a 40% lead in that specific area. Choosing between these two components depends entirely on whether your workload benefits more from the higher base clock of the Intel card or the increased shader capacity of the NVIDIA model.
