The NVIDIA GeForce RTX 4090D is the objective winner, securing victory in ten out of twelve comparable specifications. Its most significant advantage over the competition is its FP32 performance, which is 1362% better. While the NVIDIA GTX 1660 SUPER maintains a lead in two categories, the massive disparity in raw computational power highlights the substantial technical gap between these two graphics processing units.

Users prioritizing maximum computational throughput should select the NVIDIA GeForce RTX 4090D for its superior FP32 performance. Conversely, the NVIDIA GTX 1660 SUPER is the appropriate choice for budget-conscious buyers, as it offers an 86% advantage in MSRP. Choosing between these components depends entirely on whether the user requires the highest possible performance ceiling or the most cost-effective entry point based on the provided manufacturer suggested retail price.
