The NVIDIA RTX 4090 is the objective winner of this comparison, securing victory in ten out of twelve measured categories. Its most significant technical advantage is its FP32 performance, which is 2671% better than that of the NVIDIA GeForce GTX 1650. This massive disparity in raw computational capability establishes the former as the superior component across the vast majority of the evaluated hardware specifications.

Choose the NVIDIA RTX 4090 if your primary requirement is maximum FP32 performance for demanding computational tasks. Conversely, the NVIDIA GeForce GTX 1650 is the appropriate selection for users prioritizing a lower MSRP, as it holds a 91% advantage in that specific category. Your decision should depend on whether you value the extreme processing power of the newer card or the significant cost efficiency offered by the older model.
