The NVIDIA RTX 4070 is the objective winner of this comparison, securing victory in nine out of twelve measured specifications. Its most significant advantage over the AMD Radeon RX 550 is its FP32 performance, which is 2307% higher. While the AMD Radeon RX 550 holds a lead in three categories, the sheer scale of the performance gap in computational power establishes the NVIDIA RTX 4070 as the superior component in this technical evaluation.

Choose the NVIDIA RTX 4070 if your primary requirement is maximum FP32 performance for demanding computational tasks. Conversely, the AMD Radeon RX 550 is the appropriate selection for users prioritizing a lower MSRP, as it holds an 87% advantage in that specific category. Your decision should depend on whether you value the substantial raw performance lead of the former or the cost-focused positioning of the latter.
