The NVIDIA GTX 1660 Ti is the objective winner of this comparison, securing victory in eight out of twelve measured specifications. Its most significant advantage over the AMD Radeon RX 550 is its FP32 performance, which is 349% higher. While the AMD Radeon RX 550 holds a 72% advantage in MSRP, the NVIDIA GTX 1660 Ti dominates the technical landscape by providing substantially greater raw computational power across the majority of the evaluated hardware categories.

Users prioritizing maximum computational throughput should select the NVIDIA GTX 1660 Ti to leverage its superior FP32 performance. Conversely, the AMD Radeon RX 550 is the appropriate choice for budget-conscious buyers who prioritize a lower MSRP above all other technical specifications. By evaluating these specific advantages, users can align their purchase with either a focus on high-end processing capabilities or a strict adherence to the lower cost profile offered by the alternative.
